Probably the easiest way is to change your query to use a
CASE
statement when selecting, for example:
SELECT CASE columnValue WHEN 0 THEN 'passed' WHEN 1 THEN 'returned' WHEN 2 THEN 'waiting' ELSE 'invalid code' END AS ReadableStatus FROM tableName
Otherwise, you will probably need to create a TypeConverter to use in the column's
