The SQL Communication Area (SQLCA)The SQL Communication Area ( SQLCA) is an area of memory that is used on every database request for communicating statistics and errors from the applicationto the database server and back to the application. The SQLCA is used as a handle for the application-to-database communicationlink. It is passed in to all database library functions that need to communicate with the database server. It is implicitlypassed on all embedded SQL statements.A global SQLCA variable is defined in the interface library. The preprocessor generates an external reference for the globalSQLCA variable and an external reference for a pointer to it. The external reference is named sqlca and is of type SQLCA.The pointer is named sqlcaptr.
The Sqlext.h header file contains prototypes for the functions and features in the Level 1 and Level 2 API conformance levels. The Sqltypes.h header file contains type definitions and indicators for the SQL data types. The header files all contain a #define, ODBCVER, that an application or driver can set to be compiled for different versions of. The SQLCA is defined in the header file sqlca.h, which you include in your program using either of the following statements: EXEC SQL INCLUDE SQLCA; #include sqlca.h Oracle updates the SQLCA after every executable SQL statement. (SQLCA values are unchanged after a declarative statement.). D Pro.C/C Examples. This appendix presents examples using the Oracle Streams Advanced Queuing (AQ) Pro.C/C interface. You must set up data structures similar to the following for certain examples to work.
The actual global variable is declared in the imports library.The SQLCA is defined by the sqlca.h header file, included in the SDKInclude subdirectory of your installation directory.
