    Error PLS-00231

    32685
      Hello

      In the select statement of a cursor I need to perform some reasonably complex calculations on a variety of columns. I was hoping to use a set of functions defined in a package to perform the calculations, but I am getting the
      PLS-00231 function 'string' may not be used in SQL
      Error, is the only way round this to take the functions out of the package and have them as separate functions, or will it work if I simply put them in a separate package from the one that contains the cursor?

      Cheers

          Try adding the PRAGMA to the function.
          FUNCTION function_name(...) RETURN VARCHAR2 ;
              PRAGMA RESTRICT_REFERENCES(function_name, WNDS, RNDS, WNPS,RNPS);

            There are a number of things it could be.

            My #1 candidate is, we can only use functions in SQL statements that are public i.e. declared in a package spec. This is the case even for SQL statements executed within the same Package Body. The reson is that SQL statements are executed by a different engine which can only see publicly declared functions.

            Cheers, APC

              Hi Andrew

              That's exactly it! I moved the functions back to the original package, published them in the spec and it worked. Excellent!

              Cheers

                Great!!

                Helped me a lot

                Though the message - function XX may not be used in SQL, is not relevent.

                      Thanks a lot, I just Googled the error PLS-00231, the very first link brought me here, and you were spot on. Declare the functions in the Package Spec to make them Global, and that solved the issue.

                      Thanks.

                        I also have this problem.

                        Making the function public helps ... but I can not make the function public. This violates the design.

                        The PRAGMA also says that it must be right behind the function definition AND in the package specification.


                        Is there a other - a private - way?

                        (Oracle 8i / PLSQL 8.1.7.4.0)



                        I also can not split the call from the SQL Statement, because it is part of a cursor loop:
                        FOR a IN (SELECT asd,
                                                 asaa,
                                                 asdasda,
                                                 h.sssde,
                                                 HLP_FNC_GET_BLABLUBB(j.adasdassss) dasdasssss
                                          FROM   T_fhexxxsadfast h,
                                                 t_FFasee112w_SA   j
                                          WHERE  h.soasde = j.soasde) 
                                LOOP
                        anonymized code.
