string fieldName = "age"; int? fieldValue = null; // null value to be saved to the age field int numRowsAffected = ClsSql.saveNullField("myTable", "myColumn", fieldValue, "id = 1");
string fieldName = "address"; string fieldValue = null; // null value to be saved to the address field int numRowsAffected = ClsSql.saveNullField("myTable", "myColumn", fieldValue, "id = 2");In this example, we're setting the value of the "address" field to null in the "myTable" table where the id value is 2. ClsSql.saveNullField will also return the number of rows affected by this update. This function is part of the ClsSql library, which is likely packaged as a NuGet package.
