Question

In sql server 2005, how do I get the result set in table3 below? table3 is created by combining table1 and table2 like this:

table1.empid
table1.ticket
table2.identid

And update against table1 joined to table2 doesn’t work because empid isn’t unique. If need to increment to the next table2.indentid if the ID is already being used by that employee.

Also, table3 below isn’t created yet. It’s a generated set from table1 and table2. I’m using table3 as an example of what the generated set should look like.

table1
empid   ticketid   indentid
1       7          20
1       9          4
2       9          21

table2
indentid   empid
90         1
91         1
92         2

table3 
empid   ticketid  table1_indentid    table2_identid
1       7         20                 90
1       9         4                  91
2       9         21                 92

Answer 1

The only connection between table1 and table2 is empid.
The lines 1 and 2 of your table3 example have the same empid, so they should have the same table2_identid as well. Your example is not proper, or not possible to get with a query on the existing data.

But maybe this is what you want:
If you join the tables like so

SELECT empid, ticketid, t1.indentid as table1_indentid, t2.identid as table2_identid
FROM table1 AS t1
    INNER JOIN table2 AS t2 ON t1.empid = t2.empid

you will get

table3 
empid   ticketid  table1_indentid    table2_identid
1       7         20                 90
1       7         20                 91
1       9         4                  90
1       9         4                  91
2       9         21                 92
