UNION Function not working as expected
I have three tables in need to combine into one. They have the same # of columns, same columns names, data types etc. When I join table 1 & 2, using UNION, it works with no issues. When I add table 3, I get the message "Each table argument of 'UNION' must have the same number of columns". This is confusing as the tables are the same. Any ideas on what I may be missing and where to look for the problem?
Anonymous Hi! it can be a Data Type Mismatch. Check the data types of each column in Table 3 and ensure that they match exactly with those in Table 1 and Table 2.
