Can anyone please explain me the below one. I used the below query in getting the table columns info, but the max length seems to be x*2 of the actual col length. I mean if I have a col with datatype nvarchar(10) the output of my query has max_length value as '20'. I'm little confused here.. A'm I looking at the right one?
SELECT c.name ColName, t.Name 'Data type', c.max_length 'Max Length', c.precision , c.scale , c.is_nullable, ISNULL(i.is_primary_key, 0) 'Primary Key' FROM sys.columns c INNER JOIN sys.types t ON c.user_type_id = t.user_type_id LEFT OUTER JOIN sys.index_columns ic ON ic.object_id = c.object_id AND ic.column_id = c.column_id LEFT OUTER JOIN sys.indexes i ON ic.object_id = i.object_id AND ic.index_id = i.index_id WHERE c.object_id = OBJECT_ID('Table Name')
