resource
sqlite_query ( resource dbhandle, string query)
resource
sqlite_query ( string query, resource dbhandle)
Executes an SQL statement given by the query against
a given database handle (specified by the dbhandle
parameter).
For queries that return rows, this function will return a result handle
which can then be used with functions such as
sqlite_fetch_array() and
sqlite_seek().
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.
Nota:
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.
| Aviso |
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 the was an error, but undefined otherwise (it might
be TRUE for success or it might return a result handle).
