Support for Releasing Locks at Cursor Close

Open Client 15.7, Open Server 15.7, and the Embedded SQL C and COBOL 15.7 processors support the release_locks_on_close cursor option introduced in Adaptive Server 15.7.

This feature allows read locks to be released if the cursor closes. See the Adaptive Server Enterprise Reference Manual: Commands.

• Client-Library Usage
  The option parameter in the ct_cursor syntax has been extended to include CS_CUR_RELLOCKS_ONCLOSE.
• Open Server Usage
  When client applications declare a cursor with the CS_CUR_RELLOCKS_ONCLOSE option specified, Open Server sets the curstatus (cursor status) field of the SRV_CURDESC structure to SRV_CUR_RELLOCKS_ONCLOSE.
• ESQL/C and ESQL/COBOL Usage
  SQL DECLARE syntax in ESQL/C and ESQL/COBOL has been extended to include the RELEASE_LOCKS_ON_CLOSE keyword.
