Home -> Community -> Usenet -> c.d.o.server -> Re: EXEC SQL FREE :the_cursor & PCC-S-02322

However it does't work.
I can't compile EXEC SQL FREE sss_cursor/:sss_cursor/:sss_cursor_name
without error messages.
Thanks, Alex

In this case I have got as following :
Syntax error at line 18, column 16, file zzz.pc: Error at line 18, column 16 in file zzz.pc
EXEC SQL FREE sss_cursor; // Line#18

The symbol ":" was substituted for "sss_cursor" to continue.
