SQL LOOP INSERT Based on List of ID's
This is what you are asking for.
declare @IDList table (ID int)insert into @IDListSELECT idFROM table1WHERE idType = 1declare @i intselect @i = min(ID) from @IDListwhile @i is not nullbegin INSERT INTO table2(col1,col2,col3) SELECT col1, col2, col3 FROM table1 WHERE col1 = @i AND idType = 1 select @i = min(ID) from @IDList where ID > @iendBut if this is all you are going to do in the loop you should really use the answer from Barry instead.
You can just use:
Insert Into Table2 (Col1, Col2, Col3)Select col1, Col2, Col3From Table1Where idType = 1Why would you even need to loop through each id individually
INSERT INTO table2( col1, col2, col3)SELECT table1.col1, table1.col2, table1.col3FROM table1WHERE table1.ID IN (SELECT ID FROM table1 WHERE table1.idType = 1)
