Above generateSql method generates the query for all JDBC data sources.
It does not support adding a WHERE clause because through UI there is not 
enough information collected to generate WHERE clause.
Then, How does seatunnel-web support the WHERE clause for JDBC data sources?


Thanks & Regards

query
Hi Mohammad:
We can support default value in SeaTunnel Web just like we did in
https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fseatunnel.apache.org%2Fdocs%2Fconcept%2Fsink-options-placeholders%23placeholder&data=05%7C02%7Cmohammad.arshad%40visa.com%7C8d6c1c18066943c7320e08dcc89bb6eb%7C38305e12e15d4ee888b9c4db1c477d76%7C0%7C0%7C638605818343670075%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=B932PqEdwNObTnpy%2FufQS2Ao9Xkh%2BjuCzFktG6K4qko%3D&reserved=0<https://seatunnel.apache.org/docs/concept/sink-options-placeholders#placeholder>
eg:
SELECT name, age FROM test.test_table WHERE age > ${ageParam:25}. Users
should define the default value when creating a source.
WDYT?
