The SQLDA is a structure of pointers and values that provide data structure information about data being transmitted in multi-column rows. The SQLDA definition passed to the CSA provides metadata about the data being transmitted.
The SQLDA is an IBM standard; see IBM DB2
SQL Reference for more information.
With CSAs that receive data through an input pipe, you set up a SQLDA template in the program and then access the address of the actual SQLDA that Open ClientConnect sends. See Appendix F, “The SQLDA” for more explanation.
