mssql - copy different datatypes datas from one column to another column in same table

Question

I Tried to copy data's from one column to another column in same table by using following code.

UPDATE [dbo].[name] SET [name_HId] = [name_Id]

while running this query its showing an error which is

Operand type clash: int is incompatible with hierarchyid

Here the name_HId is in hierarchyid datatype and the name_Id is in int .

how can solve this problem?

Answer 1

add the slashes and then cast to hierarchyid

select cast('/' +cast(5 as varchar)+ '/' as hierarchyid)

When you cast a hierarchyid to string, it will look something like '/5/' or '/5/8/'

Answer 2

just cast the int value to varchar:

UPDATE [dbo].[name] 
SET [name_HId] = Cast([name_Id] as varchar(max))
