MDB_Common::queryAll()

MDB_Common::queryAll() – fetch result set as a nested array

Synopsis

require_once 'MDB.php';

array &queryAll ( string $query , array $types = null , integer $fetchmode = MDB_FETCHMODE_DEFAULT , boolean $rekey = false , boolean $force_array = false , boolean $group = false )

Description

Fetch the entire result set of a query and return it into a nested array. The function takes care of doing the query and freeing the results when finished.

Parameter

string $query: the SQL query

array $types: if supplied, the types of the columns in the result set will be set for fetching

integer $fetchmode: the fetch mode to use

boolean $rekey: if set to TRUE the array result be modified as follows: If the result set contains more than two columns, the value will be an array of the values from column 2 to 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).

boolean $force_array: used only if the query returns exactly two columns. If TRUE, the values of the returned array will be one-element arrays instead of scalars.

boolean boolean $group: if TRUE, the values of the returned array is wrapped in another array. If the same key value (in the first column) repeats itself, the values will be appended to this array instead of overwriting the existing values.

Return value

array - an nested array or a MDB_Error, if fail.

Throws

Possible PEAR_Error values
Error code	Error message	Reason	Solution
MDB_ERROR_NO_DB_SELECTED	NULL	No database was chosen.	Check the DSN in connect() .
MDB_ERROR_TRUNCATED	NULL	The result set contains fewer then two columns	Check the SQL query or choose another *query()** function
every other error code		Database specific error	Check the database related section of PHP-Manual to detect the reason for this error. In the most cases a misformed SQL statement. Ie. using LIMIT in a SQL-Statement for an Oracle database.
