  Hi Gopi,

  select * into TestTable from

  (

  select CAST(1 as smallint) as C1, CAST(6 as smallint) as C2

  union

  select CAST(2 as tinyint),CAST(6 as int)

  union

  select CAST(3 as bigint),CAST(6 as smallint)

  union

  select CAST(4 as int),CAST(6 as tinyint)

  ) T

  Note: Practically i want to see the difference... will u give example for that..

  Hi pksutha,

  try this query to see the resulting data type:

  SELECT RowID

  ,Col

  ,SQL_VARIANT_PROPERTY(Col,'BaseType') BaseType

  ,SQL_VARIANT_PROPERTY(Col,'Precision') Precision

  ,SQL_VARIANT_PROPERTY(Col,'Scale') Scale

  ,SQL_VARIANT_PROPERTY(Col,'TotalBytes') TotalBytes

  ,SQL_VARIANT_PROPERTY(Col,'Collation') Collation

  ,SQL_VARIANT_PROPERTY(Col,'MaxLength') MaxLength

  FROM (

  SELECT 1 AS RowID, CAST(1 AS int) Col

  UNION ALL SELECT 2 AS RowID, CAST('2' AS char) Col

  )SubQ

  And play a little with the datatypes & order of data types in the CASTs to see what the resulting data type will be.

  Best Regards,
