PL/SQL: ORA-00904:

Question

Hello..
We have custom package which is working fine since long time. But all at once we are getting compilation errors.. The following are the error messages that we are getting
233/13 PL/SQL: SQL Statement ignored
248/20 PL/SQL: ORA-00904: "SLIP_TYPE": invalid identifier
254/13 PL/SQL: SQL Statement ignored
262/20 PL/SQL: ORA-00904: "SLIP_TYPE": invalid identifier
527/16 PL/SQL: SQL Statement ignored
593/36 PL/SQL: ORA-00904: "SLIP_DATE": invalid identifier
597/16 PL/SQL: SQL Statement ignored
636/36 PL/SQL: ORA-00904: "SLIP_DATE": invalid identifier
The same package is working fine in all the other instances .

Answer 1

I don't know what else to suggest, so I'll point you to the error code:
ORA-00904:     string: invalid identifier
Cause:     The column name entered is either missing or invalid.
Action:     Enter a valid column name. A valid column name must begin with a letter, be less
than or equal to 30 characters, and consist of only alphanumeric characters and the
special characters $, _, and #. If it contains other characters, then it must be
enclosed in double quotation marks. It may not be a reserved word.And here you can see how an ORA-00904 happens.

4/3      PL/SQL: SQL Statement ignored
6/10     PL/SQL: ORA-00904: "SLIP_TYPE": invalid identifierHope this helps assuring you that the column is missing and I hope you'll find out the table and schema where this column is missing.
