Copy one row from tableA to tableB

[laurenq uantrell]

I want to copy all columns from tblA into tblB where tblA.UniqueID =
parameter @ID without having to list each column name in an insert
statement. Is this possible?
Thanks,
lq

I forgot to mention all column names and data types are identical in
tblA and tblB except for the UniqueID which is PK in tblA and not PK in
tblB.

Sure,

INSERT INTO tblB
SELECT *
FROM tblA
WHERE UniqueID = @ID

Under some circumstances, yes.

Then again, in application code, I think it is very bad practice to say:

INSERT tbl2 SELECT * FROM tbl1

SELECT * itself is bad practice, so are INSERT statements without listing
of target columns.

Why are this bad:

* You cannot see if a column is actually used.
* If the table defintion changes, the result of the SELECT changes.
* And for INSERT it is likely to result in the INSERT statment failing.
