Hi folks,

First I would like to know if there is a better forum regarding Oracle issues. I have heard that this forum is obsolete so if that is true please redirect me.

I also want to admit that I am very new to PROC and oracle.

I want to count the rows in a table using the following:

unsigned int db_count(char *table_name, char *server_id) {
   unsigned int cnt = 0;
   char sqlstmt[MAX_SQLSTMT_LENGTH];
  EXEC SQL END DECLARE SECTION;   sprintf(sqlstmt, "SELECT COUNT(*) INTO :cnt FROM %s", table_name);

  printf("sqlstmt = %s\n", sqlstmt);
  EXEC SQL WHENEVER SQLERROR DO return(sql_error(server_id, "Error counting rows in table %s.", table_name));
  EXEC SQL AT :server_id EXECUTE IMMEDIATE :sqlstmt;


Well this does not work cause I will always get 0 as an answer.

Any hints?
