# DB_common::autoExecute()

DB_common::autoExecute() -- Prepares and runs an INSERT or UPDATE query based on variables you supply

## Synopsis

``integer autoExecute` (string $table, array $fields_values [, integer $mode = `DB_AUTOQUERY_INSERT` [, string $where = `FALSE`]])`

## Description

Automatically prepares and executes INSERT or UPDATE queries.

This method builds a SQL statement using autoPrepare() and then executes the statement using execute() with it.

## Parameter

string `$table`

  name of the table

array `$fields_values`

  assoc (key => value), keys are fields names, values are values of these fields

  Values are automatically escaped and quoted according to the current DBMS's requirements.

integer `$mode`

  type of query to make (`DB_AUTOQUERY_INSERT` or `DB_AUTOQUERY_UPDATE`)

string `$where`

  a string to be used in the WHERE clause. This is only used when `$mode` is `DB_AUTOQUERY_UPDATE`. The string is put directly into the query, so you must escape and quote literals according to the DBMS's standards.

## Return value

integer - `DB_OK` on success or a DB_Error object on failure

## Throws

Table 33-1. Possible PEAR_Error values

Error code | Error message | Reason | Solution
--- | --- | --- | ---
`DB_ERROR_NEED_MORE_DATA` | insufficient data supplied | Your associative array, which has to contain fields names and their values, is empty. | Check and correct your fields_values array.
`DB_ERROR_SYNTAX` | syntax error | You use an unknown mode. | Available modes are only `DB_AUTOQUERY_INSERT` for INSERT queries or `DB_AUTOQUERY_UPDATE` for UPDATE queries.
`DB_ERROR_NODBSELECTED` | no database selected | No database was choosen. | Check the DSN in connect().
every other error code |  | Database specific error | Check the database related section of PHP-Manual to detect the reason for this error.

## Note

This function can not be called statically.

Warning
The values passed in `$data` must be literals. Do not submit SQL functions (for example `CURDATE()`). SQL functions that should be performed at execution time need to be put in the prepared statement.

## Example

Example 33-1. Using autoExecute() in insert mode
    <?php
    // Once you have a valid DB object named $db...
    $table_name = 'user';

    $fields_values = array(
        'id'      => 1,
        'name'    => 'Fabien',
        'country' => 'France'
    );

    $res = $db->autoExecute($table_name, $fields_values,
                            DB_AUTOQUERY_INSERT);

    if (PEAR::isError($res)) {
        die($res->getMessage());
    }
    ?>

Example 33-2. Using autoExecute() in update mode
    <?php
    // Once you have a valid DB object named $db...
    $table_name = 'user';

    $fields_values = array(
        'country' => 'France',
    );

    $res = $db->autoExecute($table_name, $fields_values,
                            DB_AUTOQUERY_UPDATE, "country = 'Japan'");

    if (PEAR::isError($res)) {
        die($res->getMessage());
    }
    ?>
