IN predicate against a materialized/temp table index without an order by returns wrong results ---------------------------------------------------------------------------------------------- Key: TEIID-3662 URL: https://issues.jboss.org/browse/TEIID-3662 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 8.7 Reporter: Tom Arnold Assignee: Steven Hawkins Priority: Blocker Fix For: 8.7.1.6_2, 8.12, 8.11.3 Seeing strange behavior when doing a simple select from {{SPATIAL_REF_SYS}}. This works as expected: {code} select srid, proj4text from spatial_ref_sys where srid in (3875,4326); srid | proj4text ------+---------------------------------------------------------------------------------------------------------------- 3875 | +proj=tmerc +lat_0=0 +lon_0=21 +k=1 +x_0=21500000 +y_0=0 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs 4326 | +proj=longlat +datum=WGS84 +no_defs (2 rows) {code} Swapping the values in the IN causes only one row to be returned. {code} select srid, proj4text from spatial_ref_sys where srid in (4326,3875); srid | proj4text ------+------------------------------------- 4326 | +proj=longlat +datum=WGS84 +no_defs (1 row) {code}
