How to do the eqivalent of a 'Tsql select into', into an existing table

Question

using tsql, sqlserver 2005.

I would like insert records from table table2 into an existing table table1 as easily as I could enter it into a new table table1 using:

select facilabbr, unitname, sortnum into table1 from table2

Any ideas?

Answer 1

Assuming you just want to append and that the columns match up:

INSERT INTO Table1
    SELECT facilabbr, unitname, sortnum FROM table2

If you want to replace and the columns still match:

Truncate Table1
INSERT INTO Table1
    SELECT facilabbr, unitname, sortnum FROM table2

If you want to replace and the columns do not match:

DROP Table1
SELECT facilabbr, unitname, sortnum INTO Table1 FROM table2

Answer 2

INSERT INTO table1
SELECT facilabbr, unitname, sortnum FROM table2

Answer 3

INSERT INTO TABLE1 T1 (T1.FIELD1, T1.FIELD2) SELECT (T2.FIELD1, T2.FIELD2) FROM TABLE2 T2 should work.
