How to successfully UNION ALL for double precision in PostgreSQL?
I am encountering a really strange problem.
This query does not work:
SELECT
t1.status :: TEXT,
t1.total_amount :: float AS amount
FROM accounting.payment_in_records AS t1
UNION ALL
SELECT
t1.fees :: float AS amount,
'Processed' :: TEXT AS status
FROM accounting.payment_out_record_detail_groups AS t1
WHERE t1.fees > 0;
Error:
[42804] ERROR: UNION types text and double precision cannot be matched Position: 147
But this query works:
SELECT
t1.total_amount :: float AS amount,
t1.status :: TEXT
FROM accounting.payment_in_records AS t1
UNION ALL
SELECT
t1.fees :: float AS amount,
'Processed' :: TEXT AS status
FROM accounting.payment_out_record_detail_groups AS t1
WHERE t1.fees > 0;
So the column order must be the same?

Is that your real query? I cannot see a position 2767 there...

I apologize, I was trying to simplify the question. I posted the real query, hopefully its not too much

Does it work with parentheses like this:(SELECT ...) UNION (SELECT ...)?
– Laurenz Albe
Nov 16 '18 at 12:37
No, still the same error

Hmmm. I don't see the problem right away. Try to reduce the example by removing everything that you can so that the error remains. Maybe then we can see clearer.

Yes, the order must be the same. It is not the column alias, but the column position that is the deciding factor.
See the documentation for details about “UNION compatible data types”.
The documentation has
The resolution algorithm is applied separately to each output column of a union query.
It fails to make explicit that a column is identified by its position.
