Hi Bharat,

You will not be able to modify the schema structure dyanmically within the components (for example tMySQLInput). But you can always use dynamic schema to handle the below situations where you will be storing the metdata information in a database/dictionary as reference.

Could you please try the concepts specified in below Talend blog?
