I build a query for a workbook that has several variables in the where clause (
like '%' || :variable || '%') but every time I click visualize from the query or click OK in the Diagrams "Global Where Clause" TDP changes the statement in (like ' '). What gives?
Another option would be to try using the editor and not the visual query builder - this removes the step where you need to visualize your edits. You lose the ability to "see" your query in the visualized format but you have a little more freedom in your SQL construction.
