Looping through a shell script with sql statements
Hello members,
I'm working on the Solaris environment and the DB i'm using is Oracle 10g.
Skeleton of what I'm attempting;
Write a ksh script to perform the following. I have no idea how to include my sql query within a shell script and loop through the statements. Have therefore given a jist of what I'm attempting, below.
1. Copy file to be processed (one file at a time, from a list of 10 files in the folder ).
2 . Create a snapshot(n) table : Initialize n = 1
-- creates my snapshot table and inserts records in SQL
3. Checking if the table has been created successfully:
-- query out the number of records in the table -- always fixed, say at 400000
4. If table creation is successful,
-- printing the max value to console
5. Process my files using the following jobs:
( m - initial value 001 )
( m - initial value 001 -- same as READ process_id )
-- increment m by 1
6. Wait for success log
7. looping to step1 to :
Copy file 2 to temp folder;
create snapshot(n+1) table
Exit when all the files have been copied for processing.
-- End of Step 1
Pointers on getting me moving will be very valuable.
A general solution for calling DB queries from a shell script:
You could probably assign the full output of the select to a variable and then make your comparison to validate table creation possibly like this. I don't have an Oracle DB to play with and the syntax might not be quite right but the idea should be reasonable:

I cannot get the code below to work correctly. The IF statement works just fine, but not the looping. The inner loop tries to find files for a given vendor; if found, I need to sleep giving another process time to move the files. Once the given vendor's files are gone, then I want to move on to the... (1 Reply)
Hi,
As per my understanding, we can use two shebang statements in a single shell script. Please see below snippet-
#!/bin/bash
.......## some code A
#!/bin/csh
.......## some code B
exit 0;
Here, code A will be executed using bash shell and code B will be executed with c shell.
