However, in practice, the 'TagValue' may be of different data types (float, varchar, int, etc). The right data type is known only at runtime.
Here's a couple of ideas: - Declare the column as a string, and convert the various data types to and from string format when storing/retrieving them. - Declare multiple columns, each of the appropriate data type for its value, and use the right column for the right data type thanks, bryan
