|

*
|

* If the result set contains more than two columns, the value
|

|

* set contains only two columns, the returned value will be a
|

* scalar with the value of the second column (unless forced to an
|

|
||||
* returned on errors. If the result set contains fewer than two
|
||||
* columns, a MDB2_ERROR_TRUNCATED error is returned.
|
||||
*
|
||||
* For example, if the table 'mytable' contains:
|
||||
* <pre>
|
||||
* ID TEXT DATE
|
||||
* --------------------------------
|
||||
* 1 'one' 944679408
|

* 2 'two' 944679408
|
||||
* 3 'three' 944679408
|
||||
* </pre>
|
||||
* Then the call getAssoc('SELECT id,text FROM mytable') returns:
|
||||
* <pre>
|
||||
* array(
|
||||
* '1' => 'one',
|
||||
* '2' => 'two',
|
||||
* '3' => 'three',
|
||||
* )
|
||||
* </pre>
|
||||
* ...while the call getAssoc('SELECT id,text,date FROM mytable') returns:
|
||||
* <pre>
|
||||
* array(
|
||||
* '1' => array('one', '944679408'),
|
||||
* '2' => array('two', '944679408'),
|
||||
* '3' => array('three', '944679408')
|
||||
* )
|
||||
* </pre>
|
||||
*
|
||||
* If the more than one row occurs with the same value in the
|
||||
* first column, the last row overwrites all previous ones by
|
||||
* default. Use the $group parameter if you don't want to
|
||||
* overwrite like this. Example:
|
||||
* <pre>
|
||||
* getAssoc('SELECT category,id,name FROM mytable', null, null
|
||||
* MDB2_FETCHMODE_ASSOC, false, true) returns:
|
||||
* array(
|
||||
* '1' => array(array('id' => '4', 'name' => 'number four'),
|
||||
* array('id' => '6', 'name' => 'number six')
|
||||
* ),
|
||||
* '9' => array(array('id' => '4', 'name' => 'number four'),
|
||||
* array('id' => '6', 'name' => 'number six')
|
