Question

I have a sql table that I am trying to add a column from another table to. Only when I execute the alter table query it does not pull the values out of the table to match the column where I am trying to make the connection.

For example I have column A from table 1 and column A from table 2, they are supposed to coincide. ColumnATable1 being an identification number and ColumnATable2 being the description.

I tried this but got an error…

alter table dbo.CommittedTbl
add V_VendorName nvarchar(200)
where v_venkey = v_vendorno

It tells me that I have incorrect syntax… Anyone know how to accomplish this?

Answer 1

alter table dbo.CommittedTbl
add V_VendorName nvarchar(200);

go

update c
set c.V_VendorName = a.V_VendorName
from CommittedTbl c
join TableA a
on c.v_venkey = a.v_vendorno;

go

I’m just guessing at your structure here.
