Multi-Database Joins 关注
I'm having trouble trying to make a multi-database join between two different databases. BT keeps telling me that one (usually the one I put in the "right table" option, even when I switch them around) is not a valid db and so will not let me complete the join. In addition, while it will let me select the two different databases in the left and right tables, it will not generate the drop-down box for me to select the fields that need to be joined.
I have attached an image showing how the drop-down boxes are not generated, and also the error message.
