Calling Sql/Mp System Procedures; Example 1-1. Static Sql Statements In A C Program - HP NonStop SQL/MP Programming Manual

Introduction
Example 1-1 shows an example of static SQL statements embedded in a C program:

Calling SQL/MP System Procedures

NonStop SQL/MP provides system procedures, written in TAL, that perform various
SQL operations and functions. For example, the SQLCADISPLAY procedure returns
error information from the SQLDA structure after an SQL statement runs.
You call SQL system procedures from a C program in the same manner you call other
system procedures (for example, FILE_OPEN_, FILE_CLOSE_, or WRITEREAD). The
cextdecs header file contains source declarations for these procedures that you can
include in a program. This example calls the SQLCADISPLAY procedure by using all
default parameters:
#include <cextdecs(SQLCADISPLAY)>
...
SQLCADISPLAY( (short *) &sqlca);
... /* Process information from the SQLCA structure */
