The ResultSet class provides the following functions:

• Moving within a result set in units of rows
• Returning resulting data
• Issuing a message indicating whether or not the retrieval result data is the NULL value

For details about and usage of each method provided with the ResultSet class, see the applicable JDBC manual.

(a) Multi-thread

If a single ResultSet object is used with multiple threads in parallel, operation cannot be guaranteed. Therefore, you should process a single ResultSet object by a single thread.

(b) Data mapping (conversion)

For details about the getXXX method used during the acquisition of results, see 16.3.3(1) Data mapping during retrieval data acquisition. For details about the JDBC SQL types supported by the connected database, see 16.12 Data types and character codes.
