PHP : Function Reference : SQLite Functions : sqlite_exec

sqlite_exec

Executes a result-less query against a given database (PHP 5, PECL sqlite:1.0.3)
bool sqlite_exec ( resource dbhandle, string query [, string &error_msg] )
bool sqlite_exec ( string query, resource dbhandle )

Object oriented style (method):

SQLiteDatabase {
  bool queryExec(string query,
                 string error_msg);

}

Executes an SQL statement given by the query against a given database handle (specified by the dbhandle parameter).

Warning:

SQLite will execute multiple queries separated by semicolons, so you can use it to execute a batch of SQL that you have loaded from a file or have embedded in a script.

Parameters

dbhandle

The SQLite Database resource; returned from sqlite_open() when used procedurally. This parameter is not required when using the object-oriented method.

query

The query to be executed.

error_msg

The specified variable will be filled if an error occurs. This is specially important because SQL syntax errors can't be fetched using the sqlite_last_error() function.

Note:

Two alternative syntaxes are supported for compatibility with other database extensions (such as MySQL). The preferred form is the first, where the dbhandle parameter is the first parameter to the function.

Return Values

This function will return a boolean result; TRUE for success or FALSE for failure. If you need to run a query that returns rows, see sqlite_query().

The column names returned by SQLITE_ASSOC and SQLITE_BOTH will be case-folded according to the value of the sqlite.assoc_case configuration option.

ChangeLog

Version Description
5.1.0 Added the error_msg parameter

Examples

Example 2326. Procedural example

<?php
$dbhandle
= sqlite_open('mysqlitedb');
$query = sqlite_exec($dbhandle, "UPDATE users SET email='jDoe@example.com' WHERE username='jDoe'", $error);
if (!
$query) {
   exit(
"Error in query: '$error'");
} else {
   echo
'Number of rows modified: ', sqlite_changes($dbhandle);
}
?>


Example 2327. Object-oriented example

<?php
$dbhandle
= new SQLiteDatabase('mysqlitedb');
$query = $dbhandle->queryExec("UPDATE users SET email='jDoe@example.com' WHERE username='jDoe'", $error);
if (!
$query) {
   exit(
"Error in query: '$error'");
} else {
   echo
'Number of rows modified: ', $dbhandle->changes();
}
?>


Code Examples / Notes » sqlite_exec

rrf5000

If you run a multiline SQL command (an INSERT, for example), and there is a SQL error in any of the lines, this function will recognize the error and return FALSE.  However, any correct commands before the one with the error will still execute.  Additionally, if you run changes() after such an incident, it will report that 0 rows have been changed, even though there were rows added to the table by the successful commands.
An example would be:
<?php
// create new database (OO interface)
$dbo = new SQLiteDatabase("db/database.sqlite");
// create table foo
$dbo->query("CREATE TABLE foo(id INTEGER PRIMARY KEY, name CHAR(255));");
// insert sample data
$ins_query = "INSERT INTO foo (name) VALUES ('Ilia1');
INSERT INTO foo (name) VALUES('Ilia2');
INSECT INTO foo (name) VALUES('Ilia3');";
$dbo->queryExec($ins_query);
// get number of rows changed
$changes = $dbo->changes();
echo "<br />Rows changed:  $changes<br />";
// Get and show inputted data
$tableArray = $dbo->arrayQuery("SELECT * FROM foo;");
echo "Table Contents\n";
echo "<pre>\n";
print_r($tableArray);
echo "\n</pre>";
?>
The above code should show that 0 rows have been changed, but that there is new data in the table.
