I am trying to rename the column datatype from text to ntext but getting error
Msg 4927, Level 16, State 1, Line 1 Cannot alter column 'ColumnName' to be data type ntext.
query that i m using is as follows:-
alter table tablename alter column columnname ntext null
Conversion not allowed. Add new column as ntext then copy converted data to new column, then delete old column. Might consume a lot of diskspace if it’s a large table! You should use NVARCHAR(MAX) instead of NTEXT which will not be supported in the future.
Msg 4927
