A compiler in the database performs syntax and semantic checks on the source text of the SQL procedure.

The processing by the Parser involves the following stages in addition to the routine for creating any database object.

  1. The database validates the SQL statements, including any expressions, inside the procedure body.
  2. The errors or warnings encountered during validation are treated as procedure compilation errors or warnings. These are reported to the client utility as part of the success response.
  3. On successful creation of a procedure, a success response is returned to the client application with warning code = 0.
  4. If a failure is encountered, a failure parcel is returned. An error is treated as a failure. The current transaction is rolled back.
