select¶

This object generates an SQL-select statement to select records from the database.

Some records are hidden or timed by start- and end-times. This is automatically added to the SQL-select by looking for "enablefields" in the $GLOBALS['TCA'].

Warning

Do not use GET or POST data like GPvar directly with this object! Avoid SQL injections! Don't trust any external data! Secure any unknown data, for example with intval.

Quoting of fields¶

New in version 8.7: It is possible to use {#fieldname} to make the database framework quote these fields (see ext_core:Changelog/8.7/Important-80506-DbalCompatibleFieldQuotingInTypoScript):

select.where = ({#title} LIKE {#%SOMETHING%} AND NOT {#doktype})

This applies to:

select.where

but not to:

select.groupBy
select.orderBy

as these parameters already follow a stricter syntax that allow automatic parsing and quoting.

Comprehensive example¶

See PHP source code for \TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer, ContentObjectRenderer::getQuery(), ContentObjectRenderer::getWhere().

Condensed form:

10 = CONTENT
10 {
   table =
   select {
      uidInList =
      pidInList =
      recursive =
      orderBy =
      groupBy =
      max =
      begin =
      where =
      languageField =
      includeRecordsWithoutDefaultTranslation =
      selectFields =
      join =
      leftjoin =
      rightjoin =
   }
}

uidInList¶

Property

uidInList

Data type

list of record_ids / stdWrap

Description

Comma-separated list of record uids from the according database table. For example when the select function works on the table tt_content, then this will be uids of tt_content records.

Note: this is a special keyword and replaced with the id of the current record.

Example

select.uidInList = 1,2,3
select.uidInList = this

pidInList¶

Property

pidInList

Data type

list of page_ids / stdWrap

Description

Comma-separated list of pids of the record. This will be page uids (pids). For example when the select function works on the table tt_content, then this will be pids of tt_content records, the parent pages of these records.

Pages in the list, which are not visible for the website user, are automatically removed from the list. Thereby no records from hidden, timed or access-protected pages will be selected! Nor will be records from recyclers. Exception: The hidden pages will be listed in preview mode.

Special keyword: this: Is replaced with the id of the current page.
Special keyword: root: Allows to select records from the root-page level (records with pid=0, e.g. useful for the table "sys_category" and others).
Special value: -1: Allows to select versioned records in workspaces directly.
Special value: 0: Allows to disable the pid constraint completely. Requirements: uidInList must be set or the table must have the prefix "static_*".

Note

Check the doktype of your backend page. If you are trying to fetch records from a sys_folder for example, the $cObj->checkPid_badDoktypeList method will insert the following SQL into your query:

[...]WHERE (`your_requested_table_name`.`uid` = 0) AND [...]

Which might result in an empty query result, depending on your records.

Default

this

Example

Fetch related sys_category records stored in the MM intermediate table:

10 = CONTENT
10 {
   table = sys_category
   select {
      pidInList = root,-1
      selectFields = sys_category.*
      join = sys_category_record_mm ON sys_category_record_mm.uid_local = sys_category.uid
      where.data = field:_ORIG_uid // field:uid
      where.intval = 1
      where.wrap = sys_category_record_mm.uid_foreign=|
      orderBy = sys_category_record_mm.sorting_foreign
      languageField = 0 # disable translation handling of sys_category
   }
}

recursive¶

Property: recursive
Data type: integer / stdWrap
Description: Number of recursive levels for the pidInList.
Default: 0

orderBy¶

Property

orderBy

Data type

SQL-orderBy / stdWrap

Description

ORDER BY clause without the words "ORDER BY".

Example

orderBy = sorting, title

groupBy¶

Property

groupBy

Data type

SQL-groupBy / stdWrap

Description

GROUP BY clause without the words "GROUP BY".

Example

groupBy = CType

max¶

Property

max

Data type

integer + Calc +"total" / stdWrap

Description

Max records

Special keyword: "total" is substituted with count(*).

begin¶

Property

begin

Data type

integer + Calc +"total" / stdWrap

Description

Begin with record number value.

Special keyword: total: Is substituted with count(*).

where¶

Property

where

Data type

SQL-where / stdWrap

Description

WHERE clause without the word "WHERE".

Example

where = (title LIKE '%SOMETHING%' AND NOT doktype)

Use {#fieldname} to make the database framework quote these fields:

where = ({#title} LIKE {#%SOMETHING%} AND NOT {#doktype})

languageField¶

Property

languageField

Data type

string / stdWrap

Description

This defaults to whatever is defined in TCA "ctrl"-section in the "languageField". Change it to overwrite the behaviour in your query.

By default all records that have language-relevant information in the TCA "ctrl"-section are translated on translated pages.

This behaviour can be disabled by setting languageField = 0.

includeRecordsWithoutDefaultTranslation¶

Property: includeRecordsWithoutDefaultTranslation
Data type: boolean / stdWrap
Description: If content language overlay is activated and the option languageField is not disabled, includeRecordsWithoutDefaultTranslation allows to additionally fetch records, which do not have a parent in the default language.
Default: 0

selectFields¶

Property

selectFields

Data type

string / stdWrap

Description

List of fields to select, or count(*).

If the records need to be localized, please include the relevant localization-fields (uid, pid, languageField and transOrigPointerField). Otherwise the TYPO3 internal localization will not succeed.

Default

*

join, leftjoin, rightjoin¶

Property: join, leftjoin, rightjoin
Data type: string / stdWrap
Description: Enter the table name for JOIN, LEFT OUTER JOIN and RIGHT OUTER JOIN respectively.

markers¶

Property

markers

Data type

(array of markers)

Description

The markers defined in this section can be used, wrapped in the usual ###markername### way, in any other property of select. Each value is properly escaped and quoted to prevent SQL injection problems. This provides a way to safely use external data (e.g. database fields, GET/POST parameters) in a query.

Available sub-properties:

<markername>.value (value): Sets the value directly.
<markername>.commaSeparatedList (boolean): If set, the value is interpreted as a comma-separated list of values. Each value in the list is individually escaped and quoted.
(stdWrap properties ...): All stdWrap properties can be used for each markername.

Warning

Since TYPO3 8 there is a problem combining orderBy with markers caused by the quoting of the fields, see forge#87799.

Example

page.60 = CONTENT
page.60 {
      table = tt_content
      select {
         pidInList = 73
         where = header != ###whatever###
         markers {
            whatever.data = GP:first
         }
      }
}

This example selects all records from table tt_content, which are on page 73 and which don't have the header set to the value provided by the Get/Post variable "first".

page.60 = CONTENT
page.60 {
      table = tt_content
      select {
         pidInList = 73
         where = header != ###whatever###
         markers {
            whatever.value = some
            whatever.wrap = |thing
         }
      }
}

This examples selects all records from the table tt_content which are on page 73 and which don't have a header set to a value constructed by whatever.value and whatever.wrap ('something').
