  • I don't have a way to test this right now, but something like this may work. SELECT DISTINCT URFNAM FROM community_username WHERE (ASCN_NAME NOT IN (SELECT ASCN_NAME FROM log_list)) Read More

Thanks for your reply

i want to compare URFNAM,Ascn_name,Comm_name from community_username and Ascn_name,Comm_name, Reviewer_id from log_list

if URFNAM!=Reviewer_id then it has to print URFNAM from community_username.

for example log_list table have name1,name3 for ascn_name1 and Com_name1 when we compare both name1 and name2 in community_username. but name3 is not available in log_list. it should print 'name3' from community_username

This may work also

SELECT
a.URFNAM

FROM
community_username a

LEFT JOIN log_list b ON (a.ASCN_NAME = b.ASCN_NAME)

WHERE
b.ASCN_NAME IS NULL

Thanks for your work.

its showing like below

UFNAME   ASCN_name

name3      name1
name1      name2
name2      name2
name3      name2

But we need a output as below only

UFNAME   ASCN_name

name3      name1

It is showing that way from the first query or the second query I posted?
Try the second query if you haven't yet.

What is your primary key for each? These table header names are pretty confusing.

If you want to compare two table for related information you need to have a primary key that interconnects the two tables together.

Example: There are two tables. One with all users' information and a second with a list of people's cars. Trying connect the username of the person for each car.

Table 1: users
Columns: id, username, password

Table 2: cars
Columns: id, user_id, model, make, year, color

In this case we'll use the "user_id" from table 2 and match it with "id" from the "users" table.

_______________________________

Now to take a stab in the dark for your version... I would use the ASCN_name from the logs to find the URFNAM, assuming the ASCN_name is the same in each and is your primary key.

If you have the ASCN_name then just do a search for that in the community table and pull the URFNAM.

Hope this helps. If not, let me know.
