I have two tables.

<Table A>
IP_ID IP_ADDR
1 192.168.100.1
2 192.168.100.2
3 192.168.100.3
4 192.168.100.4
5 192.168.100.5
6 192.168.100.6
7 192.168.100.7
8 192.168.100.8
9 192.168.100.9
10 192.168.100.10

<Table B>
T_ID E_NAME S_ID T_ID
1 ping 2 7
2 telnet 5 6
3 telnet 6 2
4 telnet 2 3
5 ping 2 3
6 ssh 5 4
7 ftp 6 7

From the above two tables, I would like to have the following results. Instead of showing "S_ID" as just a number, I would like to show the IP address from "TABLE A" where "IP_ID" = "S_ID". And for "T_ID", it will do the same. See the expected result below.

Expected result

ID ENAME SOURCE_IP TARGET_IP
1 ping 192.168.100.2 192.168.100.7
2 telnet 192.168.100.5 192.168.100.6
3 telnet 192.168.100.6 192.168.100.2
4 telnet 192.168.100.2 192.168.100.3
5 ping 192.168.100.2 192.168.100.3
6 ssh 192.168.100.5 192.168.100.4
7 ftp 192.168.100.6 192.168.100.7

Thanks.

Try this


Select T1.T_Id,T1.E_NAME,T2.IP_ADDRE, T2.IP_ADDRE from TableA T1 inner join Table2
on T2.S_Id=T1.IP_Id and T2.T_Id=T1.IP_ID
