Export Oracle multiple tables to multiple csv files using UNIX shell scripting
Hello All,
just wanted to export multiple tables from oracle sql using unix shell script to csv file and the below code is exporting only the first table.
Can you please suggest why? or any better idea?
Code:
export FILE="/abc/autom/file/geo_JOB.csv"

Export= `sqlplus -s dev01/password@dEV3 <<EOF
SET HEADING ON
SET WRAP OFF
SET TRIMSPOOL ON
SET TRIMOUT ON
SET PAGESIZE 50000
SET COLSEP ","
SET LINESIZE 500
SET NEWPAGE NONE
SET FEEDBACK OFF
SET VERIFY OFF
SET UNDERLINE OFF

SPOOL $FILE

SELECT * FROM geo_JOB ;

export FILE="/abc/autom/file/geo_JOB2.csv"

SELECT * FROM geo_JOB2;


SPOOL OFF
EXIT
EOF`

More details, please. Like script behaviour, execution logs, undesired results, error messages, what have you. It's difficult to base an analysis on thin air... and we have nothing.



Might be worthwhile to clarify some wording in your request: You're using "export" in various contexts which may become quite confusing if not sharply discriminated. "[Ee]xport" is
- a keyword in bash (and other shells) for the "export" attribute to variables and functions "marking it for export to child processes" (man bash).
- a term in ORACLE (and other DB) context to create a backup / copy of a database and/or its tables and meta data. Fortunately, the respective SQL command is "exp".
- a variable in your code snippet above.
- used in your description for an action that doesn't necessarily comply with what you're showing in your snippet.


Now to your script. You don't show it, but I guess you should have received an SQL error message telling you it doesn't understand the "export" command. Well, it doesn't as that is a shell command that sql can't interpret and thus ignores or, worse, crashes on. The latter may be the reason why there is only one table in the spool file. The second table should be in the file if the wrong command were simply ignored.

You'd need to define the various file variables upfront, and then switch the SPOOLing from one to the next in sql.
BTW, the Export variable will be empty in above script as the space after the = will assign it such, and then bash will try to interpret / run the result of the sqlplus "command substitution", and error out on that (presumably).

Thanks for the comments
Thank you for your feedback,

Sorry for choosing a confusing variable "Export". I have changed it to Download_job.
The first table is exported to the first file as needed and unfortunately, there is no error message to show you.


here is my updated code:

Code:
export FILE="/abc/autom/file/geo_JOB.csv"

Download_job = `sqlplus -s dev01/password@dEV3 <<EOF
SET HEADING ON
SET WRAP OFF
SET TRIMSPOOL ON
SET TRIMOUT ON
SET PAGESIZE 50000
SET COLSEP ","
SET LINESIZE 500
SET NEWPAGE NONE
SET FEEDBACK OFF
SET VERIFY OFF
SET UNDERLINE OFF

SPOOL $FILE

SELECT * FROM geo_JOB ;

export FILE="/abc/autom/file/geo_JOB2.csv"

SELECT * FROM geo_JOB2;


SPOOL OFF
EXIT
EOF`

Did you read (and understand) my post to its full extent?
Try executing your code snippet step by step.

Thank you Rudic,
What do you mean step by step?
geo_JOB1.csv
geo_JOB2.csv at the beginning of the script? Can you elaborate if possible?

Regards,
Hope



Code:
export FILE="/abc/autom/file/geo_JOB.csv"

Download_job = `sqlplus -s dev01/password@dEV3 <<EOF
SET HEADING ON
SET WRAP OFF
SET TRIMSPOOL ON
SET TRIMOUT ON
SET PAGESIZE 50000
SET COLSEP ","
SET LINESIZE 500
SET NEWPAGE NONE
SET FEEDBACK OFF
SET VERIFY OFF
SET UNDERLINE OFF

SPOOL $FILE

SELECT * FROM geo_JOB ;

export FILE="/abc/autom/file/geo_JOB2.csv"

SELECT * FROM geo_JOB2;


SPOOL OFF
EXIT
EOF`

FIle = "geo_JOB.csv"

sqlplus -s dev01/password@dEV3 <<EOF

SET HEADING ON
SET WRAP OFF
SET TRIMSPOOL ON

SET COLSEP ","
SET LINESIZE 500
SET NEWPAGE NONE
SET FEEDBACK OFF
