What would be the best approach when we have to query data from more than 100 tables?

Hi, with soapui open source we can use JDBC request when we have some queries in tables, but we cannot use multiple queries in one step, each time we need to add new JDBC request. i found the solution with groovy where i can write multiple queries. Is there a better way ? I want to use all functionnalyties of soapui and less groovy steps. Thank you
