Subj:   Re: String variable concatenation in a Stored Procedure
From:   Victor Sokovin

  How can I concatenate a string variable in a stored procedure? I want to concatenate a variable in few steps but with the second step I get "Variable too long" error.  

  Here is an example of a code that I want to use:  

          DECLARE var1 VARCHAR(20000);

          set var1 = 'AAA';
          set var1 = var1 || 'BBB';

I don't know whether there is any difference between SP and usual SQL in this case. If SQL is any indication, then I would explain this error by the fact that VARCHAR literal is by default in UNICODE, and a UNICODE string length has the maximum of 32000.

     cast ('A' as VARCHAR(20000)) VC
     , VC || VC || VC ;

fails with the error message similar to yours but the following statement seems to work:

     , VC || VC || VC ;

64000 should be the maximum for Latin strings. Concatenation of 4 VCs fails.
