[firebird-support] Invalid request BLR execting UNION of views

[kokok_ko...@yahoo.es [firebird-support]]

In a database, I execute the following code:select *from  customerunionselect * 
from  customerThe above does not make sense, it is a reduced query to show the 
error. I get  "Invalid token. invalid request BLR at offset 4275. BLR syntax 
error: expected record selection expression clause at offset 4276, encountered 
24."The first thought was a database corruption, but I have restored the 
database and passed the IBFirstAID application and no errors are detected. I 
use Firebird 2.5.What else can I try?Thank you
