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 )

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.
