modifying the script and show me how to execute it.
First Requirement:
I have a requirement where I need to parameterize to generate one extract file from multiple Oracle tables through the UNIX shell script.
Here is the script which I have written to generate one tab delimited file which will fetch all the data from EMPLOYEE table.
I need to parameterize the TABLE_NAME,OWNER_NAME,USERNAME,PASSWORD and HOST to generate from 12 more tables.
So, I would like to have only one SQL to dyngenerate the extract for 12 tables by passing these parameters values when executing the scripts.
