IBM DB2 //在存储过程中创建别名

Question

I using the latest edition of IBM´s DB2 Express-C. In one of my stored procedures I am trying to add a CREATE ALIAS - Statement for an existing table.

"Unexpected token" is the error message after executing the create statement for the stored procedure.

So my question: I read the documentation for CREATE ALIAS . There is no limitation to a special context. Does anybody implment the CREATE ALIAS in a stored procedure successfuly?

This is a snipped from my DBProc:

   DECLARE SQL          varchar(450);

   SET T1 = 'M2F.m2f_k' || i_TableNr;
   SET T2 = 'M2F.m2f_k' || i_TableNr || '_zuodoc z' ;

   -- CREATE ALIAS M2F.Kxx FOR T1;
   CREATE ALIAS M2F.Kxx FOR M2F.m2f_k11;

   for_loop: 
   FOR rs AS c1 CURSOR FOR

Thank you! Oliver

Answer 1

Most DDL statements, including CREATE ALIAS , must be executed dynamically in stored procedures:

EXECUTE IMMEDIATE 'CREATE ALIAS M2F.Kxx FOR ' || T1;

Here's a link to the manuals for the latest version of DB2 for LUW.
