integer autoExecute (
string $table
,
array $fields_values
,
integer $mode
= DB_AUTOQUERY_INSERT
,
string $where
= false
)
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.
$table
name of the table
$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.
$mode
type of query to make (DB_AUTOQUERY_INSERT or DB_AUTOQUERY_UPDATE)
$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.
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 chosen. | 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. |
This function can not be called statically.
The values passed in
$data
must be literals. Do not submit SQL functions (for exampleCURDATE()
). SQL functions that should be performed at execution time need to be put in the prepared statement.
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());
}
?>
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());
}
?>
