Does not use a connection, hardcode the column to "*" and set the distinct qualifier to false. Only use this function if you have added additional constraints to the criteria, otherwise Torque does not know which table it should count the datasets in. Parameters:   c - Criteria to get the count for. public  int count(Criteria c, Connection conn)      The COUNT function returns the number of rows in a query. public  int count(Criteria c, String columnName)      Returns the number of rows in a query. Parameters:   c - Criteria to get the count for. Parameters:   columnName - Name of database Column which is counted. public  int count(Criteria c, Connection conn, String columnName)      Returns the number of rows in a query. Parameters:   c - Criteria to get the count for. Parameters:   conn - Connection to use Parameters:   columnName - Name of database Column which is counted.
