Member Function Documentation

t3lib_DB::admin_get_dbs  ) 
 

Listing databases from current MySQL connection. NOTICE: It WILL try to select those databases and thus break selection of current database. This is only used as a service function in the (1-2-3 process) of the Install Tool. In any case a lookup should be done in the _DEFAULT handler DBMS then. Use in Install Tool only! Usage count/core: 1

Returns:
array Each entry represents a database name

Reimplemented in ux_t3lib_DB.

Definition at line 947 of file class.t3lib_db.php.

References sql_select_db().

t3lib_DB::admin_get_fields tableName  ) 
 

Returns information about each field in the $table (quering the DBMS) In a DBAL this should look up the right handler for the table and return compatible information This function is important not only for the Install Tool but probably for DBALs as well since they might need to look up table specific information in order to construct correct queries. In such cases this information should probably be cached for quick delivery.

Parameters:
string Table name
Returns:
array Field information in an associative array with fieldname => field row

Reimplemented in ux_t3lib_DB.

Definition at line 984 of file class.t3lib_db.php.

t3lib_DB::admin_get_keys tableName  ) 
 

Returns information about each index key in the $table (quering the DBMS) In a DBAL this should look up the right handler for the table and return compatible information

Parameters:
string Table name
Returns:
array Key information in a numeric array

Reimplemented in ux_t3lib_DB.

Definition at line 1002 of file class.t3lib_db.php.

t3lib_DB::admin_get_tables  ) 
 

Returns the list of tables from the default database, TYPO3_db (quering the DBMS) In a DBAL this method should 1) look up all tables from the DBMS of the _DEFAULT handler and then 2) add all tables *configured* to be managed by other handlers Usage count/core: 2

Returns:
array Tables in an array (tablename is in both key and value)

Reimplemented in ux_t3lib_DB.

t3lib_DB::listQuery field,
value,
table
 

Returns a WHERE clause that can find a value ($value) in a list field ($field) For instance a record in the database might contain a list of numbers, "34,234,5" (with no spaces between). This query would be able to select that record based on the value "34", "234" or "5" regardless of their positioni in the list (left, middle or right). Is nice to look up list-relations to records or files in TYPO3 database tables.

Parameters:
string Field name
string Value to find in list
string Table in which we are searching (for DBAL detection of quoteStr() method)
Returns:
string WHERE clause for a query

Substitution for PHP function "addslashes()" Use this function instead of the PHP addslashes() function when you build queries - this will prepare your code for DBAL. NOTICE: You must wrap the output of this function in SINGLE QUOTES to be DBAL compatible. Unless you have to apply the single quotes yourself you should rather use ->fullQuoteStr()!
