Member Function Documentation

t3lib_DB::admin_get_charsets ( )

Returns information about the character sets supported by the current DBM 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.

This is used by the Install Tool to convert tables tables with non-UTF8 charsets Use in Install Tool only!

Returns:: array Array with Charset as key and an array of "Charset", "Description", "Default collation", "Maxlen" as values

Reimplemented in ux_t3lib_DB.

Definition at line 1321 of file class.t3lib_db.php.

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 1231 of file class.t3lib_db.php.

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

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 Array with tablenames as key and arrays with status information as value
