Executes an SQL statement given by the query against a given database handle (specified by the dbhandle parameter).
For other kinds of queries, this function will return a boolean result; TRUE for success or FALSE for failure.
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.
Note: Two alternative syntaxes are supported for compatibility with other database extensions (such as MySQL). The preferred form is the first one, where the db parameter is the first parameter to the function.
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.
When executing multiple queries, the return value of this function will be FALSE if the was an error, but undefined otherwise (it might be TRUE for success or it might return a result handle).
