When the precompiler encounters the include sqlca statement, it inserts the SQLCA structure declaration into the application program. SQLCA is a data structure containing 26 precompiler-determined system variables, each of which can be accessed independently.
SQLCA variables pass information to your application program about the status of the most recently executed Embedded SQL statement.
Table 3-1 describes the SQLCA variables that hold status information, return codes, error codes, and error messages generated by Adaptive Server:
