How to achieve loop or iteration over a list of values

[NirmalSharma9]

Hi Experts,

I am in process of writing a custom pattern and facing a challenge to iterate over a list of db names which are resulted as part of linux command execution on the server. It results n number of databases. 

Example:

home/dbinstance1/sqllib/db2profile && db2 list database directory

database name : databaseA

database name : databaseB

I store above db names in a table named as db_list.db_names

Now next will be another command based on the db names I got in previous step. db name will become an argument to the command as below. 

(. /home/db2inst1/sqllib/db2profile && db2 get db cfg for "databaseA")

(. /home/db2inst1/sqllib/db2profile && db2 get db cfg for "databaseB")

There are two problems here I am struggling with:

Problem 1:  how to interpolate db_names in above command?

Problem 2: How to iterate over a list of DB names in the pattern to execute next command for each database.

As we do not know how many databases are there and I want to iterate over a list of databases for the next command formation and execution; of which the results will be collected and stored in cmdb_ci_db_schema table.
