sqlite_query
(PHP 5) sqlite_query (no version information, might be only in CVS) SQLiteDatabase->query -- Executes a query against a given database and returns a result handle Descriptionresource sqlite_query ( resource dbhandle, string query ) resource sqlite_query ( string query, resource dbhandle ) Object oriented style (method): class SQLiteDatabase { SQLiteResult query ( string query ) }
Executes an SQL statement given by the query against
a given database handle.
Parameters
- query
The query to be executed.
- dbhandle
The SQLite Database resource; returned from sqlite_open
() when used procedurally. This parameter is not required
when using the object-oriented method.
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 result handle or FALSE on failure.
For queries that return rows, the result handle can then be used with
functions such as sqlite_fetch_array() and
sqlite_seek().
Regardless of the query type, this function will return FALSE if the
query failed.
sqlite_query() returns a buffered, seekable result
handle. This is useful for reasonably small queries where you need to
be able to randomly access the rows. Buffered result handles will
allocate memory to hold the entire result and will not return until it
has been fetched. If you only need sequential access to the data, it is
recommended that you use the much higher performance
sqlite_unbuffered_query() instead.
Notes| 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. However, this works only
when the result of the function is not used - if it is used,
only the first SQL statement would be executed. Function
sqlite_exec() will always execute multiple SQL
statements.
When executing multiple queries, the return value of this function
will be FALSE if there was an error, but undefined otherwise (it might
be TRUE for success or it might return a result handle).
