A VERY interesting idea, so I tested it. I changed the length of Address from 25 to 40, then I created the view (which of course worked). Then I changed the Address back to 25. Did a: select all from viewname... and got a "type mismatch in union". So nope, doesn't work...

Why not change the length of the Address from 25 to 40 before creating the view ? Then if you want , change it back to 25 after creating the view. If I am wrong bear with me as it is my first post and I just got back into R-base after a 20 year lull. Frank In a message dated 5/29/2013 3:13:42 P.M.

Trying to create a view, here's the pared down example: CREATE VIEW vCompany (CompanyID, Address) + AS SELECT companyid, address FROM company WHERE type = 'A' + UNION ALL SELECT + companyid, billingaddress FROM company WHERE type = 'B' I get a "column type mismatch in union". The problem is that the Address and the BillingAddress are different lengths. Address is Text 25 and BillingAddress is Text 40. It refuses to put the 2 together. I've tried these, and still get the mismatch: 1. Leaving out the alias column names and letting the view definition decide. 2. Creating a new column alias name like: CREATE VIEW vCompany (CompanyID, tmpAddress) + AS SELECT companyid, address FROM company WHERE type = 'A' + UNION ALL SELECT + companyid, billingaddress FROM company WHERE type = 'B' All of it gives me a union type mismatch. I cannot have different lengths of TEXT columns? Anyone think of a workaround? I'm going to be using this in a report, and I suppose I could add code to create a temp table on the fly, but I really wanted a view... Karen
