When $mode is PEAR_ERROR_TRIGGER, this parameter is expected to be an integer among E_USER_NOTICE, E_USER_WARNING or E_USER_ERROR. When $mode is PEAR_ERROR_CALLBACK, this parameter is expected to be the callback function or method. A callback function is a string with the name of the function, a callback method is an array of two elements: the element at index 0 is an object, and the element at index 1 is the name of the method to call in the object.Sets how errors generated by this DB object should be handled.or DB_FETCHMODE_ASSOC, possibly bit-wise OR'ed with DB_FETCHMODE_FLIPPED.on this connection.Sets which fetch mode should be used by default on queriesPostgreSQL, this is emulated.Prepares a query for multiple execution with execute().

If the result set contains more than two columns, the value will be an array of the values from column 2-n. If the result set contains only two columns, the returned value will be a scalar with the value of the second column (unless forced to an array with the $force_array parameter). A DB error code is returned on errors. If the result set contains fewer than two columns, a DB_ERROR_TRUNCATED error is returned. For example, if the table "mytable" contains: ID TEXT DATE -------------------------------- 1 'one' 944679408 2 'two' 944679408 3 'three' 944679408 Then the call getAssoc('SELECT id,text FROM mytable') returns: array( '1' => 'one', '2' => 'two', '3' => 'three', ) ...while the call getAssoc('SELECT id,text,date FROM mydate') returns: array( '1' => array('one', '944679408'), '2' => array('two', '944679408'), '3' => array('three', '944679408') ) Keep in mind that database functions in PHP usually return string values for results regardless of the database's internal type.associative array using the first column as the key.Fetch the entire result set of a query and return it as anan nested array, or a DB errorFetch all the rows returned from a query.PEAR_ERROR_RETURNE_USER_NOTICE''DB_FETCHMODE_DEFAULTDB_ibaseDB_msqlDB_mssqlDB_mysqlDB_oci8DB_odbcDB_pgsqlDB_sybase
