Teradata Mode Communications Area - Preprocessor2 for Embedded SQL

Teradata Mode Communications Area

When writing COBOL programs for Teradata mode, define one SQLCA per program. For example, if an application consists of one main program and two subprograms, the main program and each of the subprograms must contain an SQLCA.

Declare the SQLCA in the WORKING STORAGE SECTION of the program, in one of two ways:

Code an EXEC SQL INCLUDE SQLCA statement, which causes PP2 to generate the structure.

Code the SQLCA directly into the application. The structure must be named SQLCA and must be unique.

Declare an SQLCA structure in COBOL as:

01    SQLCA.

      05 SQLCAID           PIC X(8) VALUE ’SQLCA   ’.

      05 SQLCABC           PIC S9(9) <comp> VALUE +136.

      05 SQLCODE           PIC S9(9) <comp>.

      05 SQLERRM.        

         49 SQLERRML       PIC S9(4) <comp>.

         49 SQLERRMC       PIC X(70).

      05 SQLERRP           PIC X(8).

      05 SQLERRD OCCURS 6 TIMES PIC S9(9) <comp>.

      05 SQLWARN.

         10 SQLWARN0       PIC X(1).

         10 SQLWARN1       PIC X(1).

         10 SQLWARN2       PIC X(1).

         10 SQLWARN3       PIC X(1).

         10 SQLWARN4       PIC X(1).

         10 SQLWARN5       PIC X(1).

         10 SQLWARN6       PIC X(1).

         10 SQLWARN7       PIC X(1).

         10 SQLWARN8       PIC X(1).

         10 SQLWARN9       PIC X(1).

         10 SQLWARNA       PIC X(1).

      05 SQLEXT             PIC X(5). 

where <comp> is COMP-5 for MF COBOL and COMP for all other COBOL compilers.

SQLCA is documented in SQL Stored Procedures and Embedded SQL (B035‑1148).
