sqlite_exec

SQLITE_EXEC(3)															    SQLITE_EXEC(3)

sqlite_exec - Executes a result-less query against a given database

SYNOPSIS

       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.

	      if (!$query) {
		  exit("Error in query: '$error'");
	      } else {
		  echo 'Number of rows modified: ', sqlite_changes($dbhandle);
	      }
	      ?>

       Example #2

	      Object-oriented example

	      <?php
	      $dbhandle = new SQLiteDatabase('mysqlitedb');

	      if (!$query) {
		  exit("Error in query: '$error'");
	      } else {
		  echo 'Number of rows modified: ', $dbhandle->changes();
	      }
	      ?>
