# setFetchMode

If you have multiple connection objects, and want to have different fetch modes for each connection, then use SetFetchMode. Once this function is called for a connection object, that connection object will ignore the global variable `$ADODB_FETCH_MODE` and will use the internal fetchMode property exclusively.

##### See Also

$ADODB_FETCH_MODE
getFetchMode()

##### Syntax

      int setFetchMode(
      optional int $fetchMode
      )

### Use as a getter

Use

    setFetchMode()

without an argument to return the current fetch mode

### Constants

Name | Value | Description
--- | --- | ---
ADODB_FETCH_DEFAULT | 0 | The recordset is returned in the default provided by the PHP driver. Use of this value is not recommended if writing cross-database applications
ADODB_FETCH_NUM | 1 | The recordset is returned as a numeric array
ADODB_FETCH_ASSOC | 2 | The recordset is returned as an associative array
ADODB_FETCH_BOTH | 3 | The record is returned as both a numeric and associative arrays. This option is not supported by all databases

## Usage

    $db->setFetchMode(ADODB_FETCH_NUM);

    $rs1 = $db->Execute('select * from table');

    $db->setFetchMode(ADODB_FETCH_ASSOC)

    $rs2 = $db->Execute('select * from table');

    print_r($rs1->fields);
    /*
      shows _array([0]=>'v0',
                   [1] =>'v1')
    */
    print_r($rs2->fields);
    /*
     * shows _array(['col1']=>'v0',
                    ['col2'] =>'v1')
     */
