BUG: ESQL-C: Nested C Structures May Cause Precompile Errors

• Microsoft SQL Server, version 6.5

SYMPTOMS

When you precompile ESQL-C code containing a named 'C' structure that is declared within another 'C' structure, you may receive warnings, such as either of the following:

   Warning: example1.sqc, line 54: syntax error.
   {
   Warning: example1.sqc, line 56: syntax error.
   } tb;

WORKAROUND

To work around this problem, either completely avoid declaring named 'C' structures within other structures, or ensure that the nested (embedded) structure is anonymous (has no tag). For example, use a structure similar to the following:

   struct a_type
   {
      /* anonymous structure */
      struct        /* no tag */
      {
         int c;
      } t_b;
   } t_a;

STATUS

Microsoft has confirmed this to be a problem in Microsoft Embedded SQL for C Programmer's Toolkit version 6.5. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
