Checking data types. The first way to check data types for SQL Server database is a query with the SYS schema table. The below query uses COLUMNS and TYPES tables:

    SELECT C.NAME AS COLUMN_NAME,
       TYPE_NAME(C.USER_TYPE_ID) AS DATA_TYPE,
       C.IS_NULLABLE,
       C.MAX_LENGTH,
       C.PRECISION,
       C.SCALE
FROM SYS.COLUMNS C
JOIN SYS.TYPES T
     ON C.USER_TYPE_ID=T.USER_TYPE_ID
WHERE C.OBJECT_ID=OBJECT_ID('your_table_name');

In this way, you can find data types of columns.
