MDB_Common::getAssoc()

MDB_Common::getAssoc() -- fetch result set as associative array

Synopsis

require_once 'MDB.php';

array &getAssoc (string $query, array [$types = NULL], array [$params = array()], array [$param_types = NULL], integer [$fetchmode = MDB_FETCHMODE_DEFAULT], boolean [$force_array = FALSE], boolean [$group = FALSE])

Description

Fetch the entire result set of a query and return it as an associative array using the first column as the key. The function takes care of doing the query and freeing the results when finished. 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).

Parameter

string $query

the SQL query

array $types

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

array $params

if supplied, prepareQuery()/ executeQuery() will be used with this array as execute parameters

array $param_types

if supplied, the values in $param will automatically set to the passed datatypes

integer $fetchmode

the fetch mode to use

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 - associative array with results from the query.

Throws

Table 26-1. Possible PEAR_Error values

Error codeError messageReasonSolution
MDB_ERROR_INVALID NULL SQL statment for preparing is not valid. See the prepareQuery() documentation, if you want to use a SQL statemt using wildcards.
MDB_ERROR_NEED_MORE_DATA NULL To less data for filling the prepared SQL statment. Check the number of wild cards given in the SQL statment prepareQuery() . Check the count of entries in the array for $params. The count of entries have to be equal to the number of wild cards.
MDB_ERROR_NO_DB_SELECTED NULL No database was choosen. Check the DSN in connect() .
MDB_ERROR_TRUNCATED NULL The result set contains fewer then two columns Check the SQL query or choose another get*() 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 statment. Ie. using LIMIT in a SQL-Statment for an Oracle database.
