This is a lightweight frontend to the DBCacheContrib. The provided macros DBQUERY and DBCALL can be used as a replacement for SEARCH and INCLUDE that use the database store instead of searching and extracting on the raw topic files.

DBQUERY is provided to ease the use of WikiApplications based on the DBCacheContrib combining its flexible query language with unrestricted formatting and an extend mechanism to extract topic properties.

DBCALL is named "call" and not "include" as its main purpose is to ease WikiApplications where TopicFunctions are treated as stored procedures. It fetches pre-compiled topics or sections of it. "Glue" chars (see Foswiki:Extensions:GluePlugin) are applied in advance so that the actual rendering time is minimized. DBCALL does therefore not allow to call "external" pages as INCLUDE allows. DBCALL's "warn" parameter can only be set to "on" and "off" and does not allow alternative content in case of a warning. The "pattern" feature used to extract a fragment from an INCLUDEd text using regular expression has been dropped. That aside, DBCALLs can be called recursively as INCLUDEs can, parametrized using key-value arguments and obeys to %STARTINCLUDE%, %STOPINCLUDE%, %STARTSECTION{"..."}% and %ENDSECTION{"..."}%.

Using the DBCacheContrib topic sections are stored into the topic object of the database. The section between %STARTINCLUDE% … %STOPINCLUDE% is called _sectiondefault whereas all sections between %STARTSECTION{"<name>"}% …. %ENDSECTION{"<name>"}% are called _section<name> and are stored accordingly.

In addition, DBCALL implements so called TopicMethods. A method call is of the form %DBCALL{"SomeTopic→RenderMethod" ...}% and will infer the actual ...RenderMethod to be called on the base of the TopicType of SomeTopic. TopicTypes are a concept introduced by the Foswiki:Extensions.WorkbenchAddOn. It basically refers to a convention to tag the type(s) of a topic in a formfield "TopicType". The lookup mechanism for TopicMethods proceeds as normal if the DBCALl is not of the form "SomeTopic→RenderMethod". For example, if SomeTopic is of type Video, MediaType, ClassifiedTopic the lookup mechanism will try to find the methods VideoRenderMethod, MediaTypeRenderMethod and ClassifiedTopicRenderMethod in the given order and use the one found first. The web these types are defined in is inferred on the base of the DataForm definitions of each of these types. If none of these type-specific methods is found the method call will fallback to a normal non-specific function call. The TopicMethod itself is called with an implicit parameter OBJECT that refers to SomeTopic, that is the object this method has been called for.

DBRECURSE iterates over topics in a web following a certain topic-to-topic relation, like the parent-child relation among topics. You can define arbitrary relations using filters.



Fetch topic content or a section of it from the database store.

%DBCALL{"<topic" … }%
"<topic>" topic that we'd like to call
section="..." optional named section; without this parameter the "default" section is used
<key>="<value>" topic arguments to be substituted within the included text; that is every occurrence of <key> is substituted with <value>
warn="on,off" enable/suppress error warnings
remote="on,off" switch fixing WikiWords in transcluded content; on means "don't touch, this is remote content" defaults to "off" because that's the default behaviour of %INCLUDE{}% (note, DBQUERY defaults to "on" aka do-not-touch-mode)


Display the database record of a topic (useful for debugging).

%DBDUMP{"<topic>" … }%
"<topic>" topic that we'd like to debug
web="..." name of the web to look for the given topic; note that you can use the dot-notation in specifying the web.topic also


DBQUERY can be used in either of two modes (a) as a pure search tool or (b) as a tool to extract properties of (a set of) known topics.

%DBQUERY{"<search>" … }%
"<search>" search clause, see below
topics="..." or topic="..." set of topics to consult (mode (b)); if "topics" are specified in addition to a "search" it will be restricted to the given topics
web="..." web where to search for hits; defaults to the current one
webs="..." regular expression of webs to be searched for; if specified takes higher precedence than web; can also be all to search in all webs or a comma-separated list of webs to search in
format="..." format string to display search hits; defaults to "$topic"; the special format string "none" disables the format string
header="..." format string to prepended to the list of hits
footer="..." format string to appended to the list of hits
separator="..." format string used to separate hits; defaults to "$n"; the special separator "none" disables separation
include="..." pattern each found topic name must match to be considered a hit; can also be a comma separated list of topics
exclude="..." pattern each found topic name must not match to be considered a hit; can also be a comma separated list of topics
sort="..." specifies the sorting of hits; this can be a comma separted list of attributes to specify more complicated sortings; special value "random"; defaults to "name"
reverse="..." specify if hits should be sorted in reverse order; defaults to "off"
limit="..." maximum number of topics to include in the hit set
skip="..." number of topics to skip while constructing the hit set; defaults to "0"
hidenull="..." flag to indicate that an empty hit set should not be displayed
remote="on,off" switch fixing WikiWords in transcluded content; on means "don't touch, this is remote content" defaults to "on"

Following variables are expanded in format strings:
  • $percnt: % sign
  • $dollar: $ sign
  • $quot: " sign
  • $n: newline
  • $nop: "empty string"
  • $count: the number of hits
  • $index: the current row index in the search
  • $web: the web where the hits where found
  • $formfield(<formfield-name>): the value of the given formfield
  • $formatTime(<formfield-accessor> [,<format>]): format the datefield pointed to by the <formfield-accessor> using the given <format>; the format can be in any form supported by Foswiki::Func::formatTime() (see Macros documentation).
  • $expand(<formfield-accessor>): return the formfield pointed to by the <formfield-accessor>
  • $html(<formfield-accessor>): same as $expand() but expands macros and TML markup
  • $d2n(<formfield-accessor>): converts a date formfield's value to epoch seconds
  • $rss(...): encode entities so that the text can be included in an rss feed
  • $encode(...): encode entities so that the text can be included in HTML input form elements
  • $flatten(...): remove any special markup producing a flattened text representation
  • $trunc(...,length): truncate a string to the given length
  • $uc(...): converts a string to upper case
  • $lc(...): converts a string to lower case

Formfield accessors:

In its most basic form $expand(Ref) is identical to $formfield(Ref). In addition $expand() can be used to refer to topic properties of related topics that can be reached from the current one using the '@' symbol. For example, if a topic A uses a form that contains a field named "Ref" and specifies a reference to another topic B (by using its name) you can access the "Headline" in B from A using $expand(@Ref.Headline).

A formfield accessor can be a composed one using 'or' and 'and'. Example: $expand(Name or Author) will expand to the value of the formfield "Name" if it exists and is non-empty and to the value of the formfield "Author" otherwise. More valid examples:
  • $expand(@Ref.Headline): headline of the referred topic
  • $expand(Nr and '.'): append a dot to the formfield value "Nr" if it exists
  • $expand(Name or Author): expand to "Name" or "Author"

A formfield accessor can be computed using TopicMarkup. If the string starts with '%', it is expanded and its result is taken as the real formfield accessor. This is useful when the name of the formfield must be computed by different means.


Traverse topic-to-topic relations, like the intrinsic parent-child relation

%DBRECURSE{"<topic>" ...}%
<topic> starting point, can be in web.topic format, defaults to the current topic
web="..." web where to recurse, defaults to the web given in the topic parameter or the current web
format="..." format string for each found topic defaults to '   $indent* [[$web.$topic][$topic]]'
single="..." format string used when only one topic is found, defaults to value of format parameter
separator="..." separator string to be put between formatted topics, defaults to '\n'
header="..." format string to be prepended to the output, empty by default
subheader="..." format string to be prepended to each subordinated search, defaults to header parameter
singleheader="..." format string to be used when only one topic is found
footer="..." format string to be appended to the output
subfooter="..." format string to be appended to each subordinated search, defaults to footer parameter
singlefooter="..." format string to be used when only one topic is found
hidenull="..." flag to indicate that an empty hit set should not be displayed
filter="..." search expression that is used in each recursion step; the current topic name is inserted into the filter expression by replacing the '$ref' string; the default filter is 'parent='$name'; this will search for topics of which the current topic is a parent
sort="..." determines the sorting order of topics in each iteration step
reverse="on,off" reverse sorting order
limit="..." maximum iterations, default is 0 (unlimited)
skip="..." skips the first n hits when formatting the output, defaults to 0 (no skip)
depth="..." only recurse to a given depth, defaults to 0 (unlimited)
include="..." regular expression topics must match to be included in the search; can also be a comma separated list of topics
exclude="..." regular expression that excludes matching topics from the search; can also be a comma separated list of topics

The ...format, ...header and ...footer format strings may contain the following variables:
  • $web: the current web
  • $topic: the current topic in the search
  • $index: the topic index number in one recursion step, that is an enumeration in each recursion step
  • $number: the "paragraph" number in the recursion, e.g. depicts the path alternative in the recursion tree
  • $count: number of found topics; this is the total number of found topics in the header and footer and the number of topics found so far during recursion
  • $indent: 3 spaces per depth
  • $indent(<string>): uses <string> for indenting the result in each depth
  • $formfield(...): see #DBQUERY
  • $expand(...): see #DBQUERY
  • $formatTime(...): see #DBQUERY

All format strings may contain the following variables:
  • $dollar: $ sign
  • $quot: " sign
  • $n: newline
  • $percnt: % sign


lists all FrequentlyAskedQuestions topics (with properly set topic parent):


Compute and format a statistics on the database.

%DBSTATS{"<search>" ...}%
"<search>" query string that defines a search, see DBCacheContrib
web="..." the web where to search in (default: current web)
field(s)="..." name of one or more formfields to be extracted (default: "text")
split="..." regex split up a field value into a list before matching each item against pattern
pattern="..." regex pattern to extract keys from the formfield(s); note, that before the pattern is applied the field value is split up using the split parameter; you must provide at least one grouping ("(...)") in the pattern string that encloses the key to be extracted (default: "^(.*)$"); you may have up to five groupings in one pattern that are accessible each in the format string
header="..." header format string to be prepended to the output
format="..." format string used for each key in the output
sep(arator)="..." separator to put between formatted keys
footer="..." footer format string to be appended to the output
sort="alpha,created" order of keys in the output
reverse="on,off" sort keys descending or ascending
limit="..." maximum number of keys to be formatted in the output
hidenull="..." flag to indicate that an empty hit set should not be displayed
include="..." regular expression that keys must match to be included in the output
exclude="..." regular expression that keys must match to be excluded from the output
casesensitive="on/off" boolean to switch on/off case sensitive matching in include and exclude; defaults to off (case insensitive match)

The DBSTATS searches for all topics in given web and reads the given form fields. It then uses the split and pattern parameters to extract all keys in the data counting their occurrences. The result is rendered using the format parameter for each token found, separating them by sep, prepend the header and append the footer. Results can be sorted alphabetically or by createdate.

Format strings (header, format, footer) can use the following variables to insert the computed statistics:
  • $key, $key1: the found key, this must match the first group in the pattern argument
  • $key2, $key3, $key4,$key5: second, third, etc grouping in the pattern argument
  • $count: the number of occurrences of the key
  • $index: index of the key within the sorted result set
  • $min: minimum count found in the search
  • $max: maximum count found in the search
  • $sum: sum of all counts
  • $mean: mean occurrence of a key in the result set
  • $keys: total number of keys found
  • $web: the web we search in
  • $topics: the list of all topics where the keys where found

For example if you want to extract all month/years from a database's Date field that has the format dd mon yyyy and then format a link to an archive using the month and the year as separate url parameters then use something like this:
%DBSTATS{"<db query>"
   pattern="((\w+) (\d\d\d\d))"
   header="---++ Archive"
   format="   * <a href="...?month=$key2&year=$key3">$key</a>"

Note, that the above pattern will crop away the day. Groups can be nested counting them from left to right, outside to inside: the first group matches the compete pattern, the second the month the third the year.


derive the title of a topic from a couple of properties:

<topic> topic we want the page title off, defaults to current topic
hideautoinc="on/off" ignore/respect autoinc topic names

  • from a TOPICTITLE preference variable, or
  • from a "TopicTitle" formfield attribute, or
  • defaults to the topic name


reference the "neigbour" documetns of an item found in a search query

%DBPREV{"<search>" … "}%*, %DBNEXT{"<search>" … "}%
"<search>" query string that defines a search, see DBCacheContrib
web="..." the web where to search in (default: current web)
topic="..." the topic from where to search for neighbours (default: current topic)
format="..." format string to render the results (default: "$web.$topic")
order define a sorting on the hit set; see above
reverse="on,off" sort keys descending or ascending

Results are rendered using the format parameter which understands the normal format tokens like $dollar, $percnt, $nop and $n as well as $web and $topic which refer to the previous or next topic in DBPREV or DBNEXT respectively.

These two macros come in handy rendering a navigation among search results found by a DBQUERY. For example, the following code will render a navigation as found in blog applications linking to the previous and next blog entry in a list of postings ordered by created date:

  search="TopicType=~'\bBlogEntry\b' AND State != 'unpublished' AND topic != 'WebTopicEditTemplate'" 
  search="TopicType=~'\bBlogEntry\b' AND State != 'unpublished' AND topic != 'WebTopicEditTemplate'" 

(from Foswiki:Extensions/BlogPlugin)

Syntax of search queries

A search query is a boolean expression on fields of a topic. (Tip: use %DBDUMP to explore the available fields).

Fields are given by name, and values by strings or numbers. Strings should always be surrounded by 'single-quotes'. Strings which are regular expressions (RHS of =, != =~ operators) use 'perl' regular expression syntax (google for perlre for help). Numbers can be signed integers or decimals. Single quotes in values may be escaped using backslash (\).

The following operators are available:
Operator Result Meaning
= Boolean LHS exactly matches the regular expression on the RHS. The expression must match the whole string.
!= Boolean Inverse of =
=~ Boolean LHS contains RHS i.e. the RHS is found somewhere in the field value.
< Boolean Numeric <
> Boolean Numeric >
>= Boolean Numeric >=
<= Boolean Numeric <=
lc String Unary lower case
uc String Unary UPPER CASE
IS_DATE Boolean Compare two dates e.g. '1 Apr 2003' IS_DATE '1 Apr 2004'
EARLIER_THAN Boolean Date is earlier than the given date
EARLIER_THAN_OR_ON Boolean Date is earlier than, or on, the given date
LATER_THAN Boolean LHS is later than the given date
LATER_THAN_OR_ON Boolean LHS is later than the given date
WITHIN_DAYS Boolean Date (which must be in the future) is within n working days of todays date
! Boolean Unary NOT
AND Boolean AND
OR Boolean OR
() any Bracketed subexpression

Dates for the date operators (IS_DATE, EARLIER_THAN etc) must be dates in the format expected by Time::ParseDate (like the ActionTrackerPlugin). WITHIN_DAYS works out the number of working days assuming a 5 day week (i.e. excluding Saturday and Sunday). Apologies in advance if your weekend is offset ± a day! Integers will automatically be converted to dates, by assuming they represent a number of seconds since midnight GMT on 1st January 1970. You can also use the d2n operator to convert a date string to such an integer.


  • Find all topics that have been last modified before 1st January 2008
    %DBQUERY{" EARLIER_THAN '1st January 2008'"}%
  • Find all topics last modified by Peter
    %DBQUERY{" =~ 'Peter'"}%
  • Find all FAQs
    %DBQUERY{"topic =~ 'FAQ'"}%
  • Find all topics that have the word "random" in it (case-insensitive) excluding the current topic
    %DBQUERY{"lc(text) =~ 'random' and topic != 'DBCachePlugin'"}%

Perl API

The DBCachePlugin supports overloading the contained default database cache by inheriting from DBCachePlugin::WebDB being itself a DBCacheContrib. The only purpose of the DBCachePlugin::WebDB is to extract the TopicFunctions contained in a topic as described above. You can easily extend this functionality by deriving a WebDB specific to your own WikiApplication. For example, the Foswiki:Extensions.BlogPlugin defines a WebDB of its own where it caches the createdate of a topic being either specified in a formfield or given in the timestamp of the first revision of a topic.



Returns a database object used for further queries. This function must be called ahead of any actual database access. If your WikiApplication is using a derived WebDB then use the WEBDB variable in your WebPreferences to point to its implementation (example: =Set WEBDB = Foswiki::Plugins::BlogPlugin::WebDB=). If WEBDB is not defined the default implementation Foswiki::Plugins::DBCachePlugin::WebDB is used. Note, that this way only one application-specific database cache can be loaded per web. This is rather a design decision; otherwise each DBQUERY and DBCALL tag would have to declare which database it operated on. So currently the rule of thumb is: one web one WikiApplication making use of this plugin.

returns a database object. See the Foswiki:Extensions::DBCacheContrib documentation for its interfaces.


This implements the database object that is used to access the topic records in a web. Note, that for each web there is exactly one WebDB database object. A database object is fetched (and initialized if needed) by the DBCachePlugin::getDB() function.


The DBQUERY functionality can be access from within perl using the plugins dbQuery() method.

(@$topicNames, %$topicObjs, $errorMsg) = $db→dbQuery([$search, @$topics, $order, $reverse, $include, $exclude])
exclude pattern that topic names must not match to be considered a hit
include pattern that topic names must match to be considered a hit
order define a sorting on the hit set; this can be any formfield accessor or one of the shortcuts "created" (for createdate) or "modified" (for provided for compatibility with default %SEARCH
reverse=on,off revert the sorting order
search search clause
topics restrict search to this list of topics
webDB database object

returns a list pointer of all found topics names, a hash pointer to an array of all found topic objects (keys are the name of the topics) and a possibly defined error message.


Access the formfield value of an arbitrary topic.

$value = $db→getFormField($topic, $formfield)
topic a topic name
formfield a formfield name

returns the value of the named formfield

Plugin Settings

See also DBCacheContrib for additional configuration settings.

Each web can specify an alternative implementation inheriting from DBCachePlugin::WebDB. To specify it you have to set the WEBDB variable in the WebPreferences. The default is Foswiki::Plugins::DBCachePlugin::WebDB


If $Foswiki::cfg{DBCache}{MemoryCache} is set to FALSE (defaults to TRUE) the dbcache once loaded into memory will stay there among multiple requests. This option only has an effect using speedy/perperl or fastcgi setups.


When enabling $$Foswiki::cfg{SecureTopicTitles}, TopicTitles will only be used as a link text in WikiWords when the user has got view access to the target topic.

Installation Instructions

You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.

Open configure, and open the "Extensions" section. Use "Find More Extensions" to get a list of available extensions. Select "Install".

If you have any problems, or if the extension isn't available in configure, then you can still install manually from the command-line. See for more help.

WARNING: before using DBCachePlugin on your site do take down your web server and run

cd <foswiki-root>/bin; ./rest /DBCachePlugin/updateCache

to generate all caches initially. Then switch on the web server again. The cache will be maintained automatically from there on.
