Simple question but i can't seem to find what i need, as examples are giving me only where id=1 etc.

pseudo code of what i'm wanting to achieve but doesn't work (errors)

SQL

INSERT INTO tableB b
SELECT a.l_desc, a.s_desc FROM tableA a where on a.id = b.id

id's are same in both tables so insert the correct descriptions

Solution 1

you should use update query instead of insert as you already have record in your tableB

SQL

update   b set l_desc=a.l_desc,s_desc=a.s_desc
from tableB , tableA a where a.id = b.id

FROM tableA a WHERE a.id=tableB.id

Solution 2

your tableB have b.id values already so you can't use insert Query .your only option Update it

SQL

update   b set b.l_desc=a.l_desc,b.s_desc=a.s_desc
from tableB as b inner join tableA a where a.id = b.id
