Compare values in two files. For matching rows print corresponding values from File 1 in File2.

- I have two files (File 1 and File 2) and the contents of the files are mentioned below.
- I am trying to compare the values of Column1 of File1 with Column1 of File2. If a match is found, print the corresponding value from Column2 of File1 in Column5 of File2.

- I tried to modify and use the solution provided in the forum for a similar problem, but did not get the required result.

Code:
awk 'NR==FNR{A[$1]=$2}A[$3]{sub($3,A[$3]);print}' file2 file1

Code:

Code:
awk 'NR==FNR{A[$1]=$2;next} A[$1]{$5=A[$1];print}' file2 file1

You may lose the tabs which separate the fields, however.

Thank you very much for the response Otheus. I tried using the solution, column2 in the output printed below seems fine against the two columns 1 & 3. But the output is missing the rest of the columns from file2. The last column has SQL Statment which runs into multiple lines, so I am mainly concerned as to how it will show up once that column is included in the output.

Code:
=> awk 'NR==FNR{A[$1]=$2;next} A[$1]{$5=A[$1];print}' file2 file1

Column1 of File1 with Column1 of File2. If a match is found, print the corresponding value from Column2 of File1 in Column5 of File2.
I think my answer is correct but you have the files on the command line in the wrong order.
Code:
awk 'NR==FNR{A[$1]=$2;next} A[$1]{$5=A[$1];print}' file1 file2

Thank You so much. It worked, as you said the spaces between the fields are gone.

---------- Post updated 05-17-12 at 12:25 AM ---------- Previous update was 05-16-12 at 11:36 AM ----------

In some environments, the file has around 800 lines hence it is difficult to read from the file. This output will be generated 30 mins once and 24/7. I am trying to add spaces upon identification of a space, but this is failing to give the output in a formatted manner. Can you please help. A portion of output is printed below.

would you be able to break this down pls so i can understand how it's achieving the result? I have a similar problem and i think i should be able to tweak this if i can understand it. thanks

Hello Jack,

This is what I am trying to do :

1) Running the below query against the DB2 database.

Code:
db2 "SELECT SUBSTR(T1.AGENT_ID,1,8) AS APPL_HANDLE,
        CASE APPL_STATUS
        WHEN 'AUTONOMOUS_WAIT' THEN 'AUTONOMOUS_WAIT'
        WHEN 'BACKUP' THEN 'DB_BACKUP'
        WHEN 'COMMIT_ACT' THEN 'COMMIT'
        WHEN 'COMP' THEN 'COMPILING'
        WHEN 'CONNECTED' THEN 'CONNECTED'
        WHEN 'CONNECTPEND' THEN 'CONNECT_PENDING'
        WHEN 'CREATE_DB' THEN 'CREATE_DB'
        WHEN 'DECOUPLED' THEN 'DECOUPLED'
        WHEN 'DISCONNECTPEND' THEN 'DISCONNECT_PENDING'
        WHEN 'INTR' THEN 'REQUEST_INTERRUPTED'
        WHEN 'IOERROR_WAIT' THEN 'TBLSPCE_DISABLE_WAIT'
        WHEN 'LOAD' THEN 'LOAD'
        WHEN 'LOCKWAIT' THEN 'LOCKWAIT'
        WHEN 'QUIESCE_TABLESPACE' THEN 'QUIESCE_TBLSPCE'
        WHEN 'RECOMP' THEN 'RECOMPILING'
        WHEN 'REMOTE_RQST' THEN 'FEDRATD_RQST_PENDING'
        WHEN 'RESTART' THEN 'DB_RESTART'
        WHEN 'RESTORE' THEN 'DB_RESTORE'
        WHEN 'ROLLBACK_ACT' THEN 'ROLLBACK'
        WHEN 'ROLLBACK_TO_SAVEPOINT' THEN 'ROLLBACK_SAVEPOINT'
        WHEN 'TEND' THEN 'TRANSACTION_ENDED'
        WHEN 'THABRT' THEN 'GLOBAL_TRANSN_ROLLBK'
        WHEN 'THCOMT' THEN 'GLOBAL_TRANSN_COMMIT'
        WHEN 'TPREP' THEN 'TRANSACTION_PREPARED'
        WHEN 'UNLOAD' THEN 'DATA_FAST_UNLOAD'
        WHEN 'UOWEXEC' THEN 'EXECUTING'
        WHEN 'UOWQUEUED' THEN 'QUEUED'
        WHEN 'UOWWAIT' THEN 'WAITING'
        WHEN 'WAITFOR_REMOTE' THEN 'PENDING_REMOTE_RQST'
        ELSE ''
        END AS APPL_STATUS,
        CAST(T1.STATUS_CHANGE_TIME AS DATE)||'-'||CAST(T1.STATUS_CHANGE_TIME AS TIME) as STATUS_CHANGE_TIME,
        SUBSTR(PRIMARY_AUTH_ID,1,15) AS AUTH_ID,
        SUBSTR(T1.TPMON_CLIENT_USERID,1,15) as CLIENT_USERID,
        T2.STMT_OPERATION,
        SUBSTR(T2.STMT_TEXT,1,2000) as STMT_TEXT
FROM TABLE(SNAP_GET_APPL_INFO(CAST(NULL AS VARCHAR(128)),-1)) AS T1,
     TABLE(SNAP_GET_STMT('',-1)) AS T2
WHERE T1.AGENT_ID=T2.AGENT_ID"|sed -e 's/[ \t]*$//' -e '5d' -e 'N;$!P;$!D;$d' > File1.out


2) The field "SUBSTR(T1.TPMON_CLIENT_USERID,1,15) as CLIENT_USERID" in the query is not returning any value but the rest of fields in the SELECT are.

3) Since I am not getting the value for the field - "SUBSTR(T1.TPMON_CLIENT_USERID,1,15) as CLIENT_USERID", I am running the below query to get the output. - (Checked in the DB2 Forums about it. Yet to get a response on this)

Code:
db2 "get snapshot for applications on $2 AT DBPARTITIONNUM $CORD_PART "| grep -e "Application handle                         =
Client login ID                            = "|awk -F "=" '{print $2}' > Intermediate.out

4) I am then doing a row to column transpose of the output present in the file - Intermediate.out

Code:
paste -d' ' - - < CON_AUTH_CLNT.out > File2.out

5) Comparing the value "SUBSTR(T1.AGENT_ID,1,8) AS APPL_HANDLE" in File1.out with "Application handle" value in File2.out, if there is a match printing the value "Client login ID" from File2.out in the 5th column of File1.out. (Suggested by Otheus)

Code:
awk 'NR==FNR{A[$1]=$2;next} A[$1]{$5=A[$1];print}' File2.out File1.out > Final.out

6) The script will be run 30 mins once and 24/7 in multiple database environments. A team will review the results periodically. The output can sometimes be a 1000 lines which makes it hard to read (SQL Statements can themselves run into 100's of lines).

7) Below is a portion of the output.

Code:
