What you exactly wan't to do ?. To change Datatype of column you can simple use alter command as

ALTER TABLE table_name ALTER COLUMN LoginDate DateTime;

But remember there should valid Date only in this column however data-type is nvarchar.

If you wan't to convert data type while fetching data then you can use CONVERT function as,

CONVERT(data_type(length),expression,style)

eg:

SELECT CONVERT(DateTime, loginDate, 6)

This will return 29 AUG 13. For details about CONVERT function you can visit ,

Remember, Always use DataTime data type for DateTime column.
