Question

I have a table that is basically set up so there is an id(UNIQUE),mapID,employe_ID, and a value… it looks sort of like this

Table

ID    mapID       employee_id     value
1       1         1               Brian
2       1         1               617-555-5555
3       1         2               Boston Office
4       1         2               Mary
5       3         1               617-666-6666
6       3         2               New york office

I want to loop thru this table so “for each” same employee_id, I can do an insert statement into another table where it is setup a little cleaner.

Like this will give you rough idea of what i am trying to convey.

Select * from table where employe_id=1
foreach(item in aboveSelect)
{
   Insert into table2
}

Obviously this is not the correct syntex.

Don’t “foreach loop” over SQL data – use the data as sets. So in your case – do it this way:

INSERT INTO dbo.Table2(Col1, Col2, ...., ColN)
  SELECT Col1, Col2, ...., ColN
  FROM dbo.table 
  WHERE employee_id=1

Nice, fast, set-oriented….
