`bool` `maxdb_stmt::execute`

The `maxdb_stmt_execute` function executes a query that has been previously prepared using the `maxdb_prepare` function represented by the `stmt` resource. When executed any parameter markers which exist will automatically be replaced with the appropiate data.

If the statement is UPDATE, DELETE, or INSERT, the total number of affected rows can be determined by using the `maxdb_stmt_affected_rows` function. Likewise, if the query yields a result set the `maxdb_fetch` function is used.

When using `maxdb_stmt_execute`, the `maxdb_fetch` function must be used to fetch the data prior to preforming any additional queries.
