except TableB contains a field "Archive_ID" which does not exist in TableA. How do I get past this? I tried the following statement:
INSERT INTO TABLEB SELECT * FROM TABLEABut because of the extra field in B, it won't work.
In an INSERT INTO... SELECT statement, the columns in the SELECT clause must match the number and the data types (loosely) of the columns in the INSERT INTO clause. To illustrate, here are two sample tables:
create table TableA ( Stuff numeric(5), MoreStuff varchar(30) ); create table TableB ( Stuff numeric(5), MoreStuff varchar(30), ExtraColumn numeric(5) );To populate TableB with data from TableA, either of the following INSERT statements will do the trick:
insert into TableB (Stuff, MoreStuff) select * from TableA; insert into TableB select Stuff, MoreStuff, null from TableA;
