String functions work only on strings. @John DorrianNo need to do duplicacy over the column, you can create a new derived column from this as I assume you need@en as your values, so just split with '|' and then in the next step use another derived column to select an index value prior to '@en' indexfrom split array column from the previous step. Return false when not found. In this document, we will primarily focus on learning fundamental concepts with various examples to explore the ability to create parameterized data pipelines within Azure Data Factory. More info about Internet Explorer and Microsoft Edge.
