created a new field in sqlserver table but cannot update it.
Ive added a new column to my tblwordtags table and I can see it in the column of the table i would like to update it, it is underlining the column the error message is;
Msg 209, Level 16, State 1, Line 5
Ambiguous column name 'ClientCode'.
this works
this does not
Use Dictionary
its strange if you look at the screenshot the column is not showing the field to choose.

The error's probably on line 3. Qualify the name there (wt.clientcode or w.clientcode) and you should be fine.

an update statement should not contain a select clause:
update wt
set clientcode= whichfielddoyouwanthere
from TblWordTags wt
LEFT JOIN tblwords w ON W.clientcodeWordPosition = wt.clientcodeWordPosition
Couple things wrong with your query:
- Line 2 : Uses the alias wt., but wt only lives in the subquery in lines 3-5, so line 2 does not know what wt. is. Remove it.
- Line 3-5: Are you certain that that query will return one and only one row? If not, you'll get a 'Subquery cannot return more than one row' error message, as line 2 attempts to assign a single value to the result of a subquery, which cannot return more than one row.
- Looks like you're setting tblWordTags.ClientCode to TblWordTags.ClientCode. Are you sure that is correct?

tblwords contains the field clientcode with clientcodewordposition as pk in both tables and i want to get each clientcodewordposition that exists in the tblwordtags and update its clientcode to the same value.
the select works here are the rows attached

I thought this might work but it doesnt
UPDATE TblWords LEFT JOIN TblWordTags ON TblWords.ClientCodeWordPosition = TblWordTags.ClientCodeWordPosition SET TblWordTags.ClientCode = [TblWords].[ClientCode]
WHERE (((TblWordTags.ClientCodeWordPosition) Is Not Null));
that would be:
update wt
set clientcode= w.clientcode
from TblWordTags wt
LEFT JOIN tblwords w ON W.clientcodeWordPosition = wt.clientcodeWordPositionASKER
