Detailed Description

A container for all state needed to execute a database query, such as the query itself, parameters for prepared statements, driver parameters, etc.

Statements may represent queries or prepared statements.

Statements may be used multiple times and can be reconfigured (e.g. they can be reused to execute multiple different queries). However, executing a statement (and changing certain other state) will invalidate result sets obtained prior to that execution.

Multiple statements may be created from a single connection. However, the driver may block or error if they are used concurrently (whether from a single thread or multiple threads).

Statements are not required to be thread-safe, but they can be used from multiple threads so long as clients take care to serialize accesses to a statement.
