SQL Descriptor Area

An SQL descriptor area (SQLDA) is a more sophisticated method for processing the result of a SELECT, FETCH, or DESCRIBE statement. An SQLDA groups the data of one row of data together with metadata items into one data structure. ecpg provides two ways to use descriptor areas: named SQLDA and C-structure SQLDA.

Named SQLDA
