SQLiteResult query

]] )
Executes an SQL statement given by the query against a given database handle. 参数
返回值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. 更新日志
注释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). |
