Dear Team, Scenario: I have source query of Sql server which made up of 14 tables ( various left outer join + inner join). I need to select 25 columns from these 14 tables. Fail in Execution: I click on "GUESS SCHEMA" but it gives an error. Please refer screenshot Those errors can be anything. Requirement: Its difficult to create schema for those 25 columns manually. Do we have any alternative idea so that Talend himself generate schema for written query ? Please let me know incase we have any alternative to get schema automatically. Thanks in advance.
