Merge statements in Pro*C

Question

First I tried doing the following:
EXEC SQL
MERGE INTO <table>
ect. etc.
And got Encountered the symbol "MERGE" when expecting one of the following:
for, register, at, close, commit, connect, declare, describe,
execute, fetch, open, prepare, rollback, select, whenever,
alter, audit, comment, create, delete, drop, get, grant,
insert, lock, noaudit, rename, revoke, set, update, validate,
arraylen, allocate, cache, call, collection, context,
deallocate, enable, free, lob, object, savepoint, analyze,
explain, truncate,
I later found out that you can't embed MERGE statements like that. So instead I tried to embed it as a PL/SQL block.
EXEC SQL EXECUTE
BEGIN
MERGE INTO <table>
USING (..)
ON (..)
WHEN MATCHED ..
WHEN NOT MATCHED ..
END;
END-EXEC;
And got the following: "MERGE INTO BENEFITS.BROKER_INFORMATION D
PLS-S-00103, Encountered the symbol "INTO" when expecting one of the following:
Does Pro*C just flat out hate merge statements?

Answer 1

Hi,
I tried out, exactly the same as you tried..
Looks like the ANSI Pro C ompiler is not equiped to compile Merge statement.
So if we can get the compiler not touch the Merge statement, our job is done.
The work around is as follows:
     /*SQL Declarations*/
          EXEC SQL BEGIN DECLARE SECTION;
                    char O_str1[1024];
                    EXEC SQL VAR O_str1 IS STRING (1024);
          EXEC SQL END DECLARE SECTION;
          strcpy(O_str1,"MERGE INTO .....");
     /*SQL query to be executed*/
          EXEC SQL PREPARE curSqlStmt FROM :O_str1;
Please try and respond, it worked for me...
