I've got the message "ERROR: variable not found in subplan target lists" when I have a union between 2 views. Both selects from the views run without the union. Same result using intersect and except. Same result using any of them with the all qualifier. Explain of the union gives the error, explain of each individual select gives a result.
The view definitions contain unions and cross joins. The error still occurs if I simplify the selects down to select 'abc' from view1 union select 'cba' from view2 "PostgreSQL 7.4 on i686-pc-linux-gnu, compiled by GCC 2.96" redhat 7.2 (2.4.7-10) klint. +---------------------------------------+-----------------+ : Klint Gore : "Non rhyming : : EMail : [EMAIL PROTECTED] : slang - the : : Snail : A.B.R.I. : possibilities : : Mail University of New England : are useless" : : Armidale NSW 2351 Australia : L.J.J. : : Fax : +61 2 6772 5376 : : +---------------------------------------+-----------------+ ---------------------------(end of broadcast)--------------------------- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
