Vikash,
double quotes tell the C compiler, where a string literal starts and
ends.  Otherwise DECLARE would be interpreted as a name of a variable
and the next word wolud be a syntax error.  Your querystr should not
*contain* the double quotes.  So

strcat(querystr,"DECLARE mycursor CURSOR FOR select * from currpass
where sitename = 'tvl'");

should do the trick.  BTW, are you sure you want strcat and not
strcpy?

Kind regards,
