Create relationship between with two columns
Dear all! I have diffrent tables with data, format something like ID | MsId | Date | [stat values] Date and MsId is not uniq each other, but unique both. How can I link my tables by two col...
Hi,
You can not use composite key.
I suggest you concatenate Date (parse to string or something) and MsId attributes, and use this as PK.
