int sqlite_changes (resource $dbhandle)
DESCRIPTION
Object oriented style (method): int SQLiteDatabase::changes (void )
Returns the numbers of rows that were changed by the most recent SQL statement executed against the $dbhandle database handle.
PARAMETERS
o $dbhandle
- The SQLite Database resource; returned from sqlite_open(3) when used procedurally. This parameter is not required when using the

RETURN VALUES

EXAMPLES
Example #1
Procedural style
<?php
$dbhandle = sqlite_open('mysqlitedb');
$query = sqlite_query($dbhandle, "UPDATE users SET email='jDoe@example.com' WHERE username='jDoe'");
if (!$query) {
exit('Error in query.');
} else {
echo 'Number of rows modified: ', sqlite_changes($dbhandle);
}
?>
Example #2
Object oriented style
<?php
$dbhandle = new SQLiteDatabase('mysqlitedb');
$query = $dbhandle->query("UPDATE users SET email='jDoe@example.com' WHERE username='jDoe'");
if (!$query) {
exit('Error in query.');
} else {
echo 'Number of rows modified: ', $dbhandle->changes();

SQLITE_EXEC(3)SQLITE_EXEC(3)sqlite_exec - Executes a result-less query against a given databaseSYNOPSIS
bool sqlite_exec (resource $dbhandle, string $query, [string &$error_msg])
DESCRIPTION
bool sqlite_exec (string $query, resource $dbhandle)
Object oriented style (method): bool SQLiteDatabase::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
o $dbhandle
- The SQLite Database resource; returned from sqlite_open(3) when used procedurally. This parameter is not required when using the
object-oriented method.
o $query
- The query to be executed. Data inside the query should be properly escaped.
o $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(3) 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(3).
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.
