How to verify a particular user is available in the database or not?

We can achieve this in four steps:

Need a SQL file to retrieve the data from the database

Need a service suite script to run the SQL query and store it in a variable to compare

Need a CSV file that contains the user or users

Implementation in .ds script

For step-1 we have to create a SQL file in the below format:

-- dbvendor=MYSQL
-- username=XXXX
-- password=XXXX
-- host=localhost
-- schema=XXXX
-- port=3306
-- connect
-- limit=1-10
-- tag=executedScenarios
SELECT * from DATABASENAME.TABLENAME
-- storeInLocker=
-- disconnect

For step-2, below are the syntax for service suite script:

processSQLFile("{ds}/sqlScript.sql");
var result = JSON.parse(locker.get("executedScenarios"));
log(result);
var xyz;
locker.put("xyz",result);

For step-3, use any CSV in below format:

For step-4, use the below step
