I'm used not to define String Length in schema editors and now I'm getting worried if maybe I should. <BR />Thanks, Greg Mon, 17 Mar 2014 09:59:42 GMT https://community.qlik.com/t5/Talend-Studio/String-default-length/m-p/2272128#M49491 _AnonymousUser 2014-03-17T09:59:42Z https://community.qlik.com/t5/Talend-Studio/String-default-length/m-p/2272129#M49492 The length of a string is only of interest if you create a database table (with the Action on Table) and here the varchar types needs a length &gt; 0. <BR />Another usage of length is in the tSchemaComplianceCheck component.<BR />If you read and write strings is does not matter what you have set as length.
