Infinispan-dsl-cache translator: comparison operators(GE,LE) problem with string -------------------------------------------------------------------------------- Key: TEIID-3627 URL: https://issues.jboss.org/browse/TEIID-3627 Project: Teiid Issue Type: Bug Components: Misc. Connectors Affects Versions: 8.7.1.6_2 Reporter: Jan Stastny Assignee: Van Halbert Fix For: 8.7.1.6_2, 8.12 Comparison of string values provides wrong results for GE and LE operators. I provide example queries, notice the number of rows returned by the queries. For query: {code:sql}SELECT BQT1.SmallA.StringNum FROM BQT1.SmallA WHERE BQT1.SmallA.StringNum <= -22 ORDER BY StringNum{code} * Process Tree: {code:plain} LimitNode(0) output=[g_0.stringNum] limit 100 AccessNode(1) output=[g_0.stringNum] SELECT g_0.stringNum FROM SmallAs.smallARemotecache AS g_0 WHERE g_0.stringNum <= '-22' ORDER BY g_0.stringNum {code} * SRC CMD: {code:sql}SELECT g_0.stringNum FROM SmallAs.smallARemotecache AS g_0 WHERE g_0.stringNum <= '-22' ORDER BY g_0.stringNum{code} * result 0 rows But for query: {code:sql}SELECT BQT1.SmallA.StringNum FROM BQT1.SmallA WHERE BQT1.SmallA.StringNum < -22 ORDER BY StringNum{code} * Process Tree: {code:plain}ProjectNode(0) output=[c.stringNum AS StringNum] [c.stringNum AS StringNum] LimitNode(1) output=[c.stringNum] limit 100 SortNode(2) output=[c.stringNum] [SORT] [c.stringNum] SelectNode(3) output=[c.stringNum] c.stringNum < '-22' AccessNode(4) output=[c.stringNum] SELECT g_0.stringNum FROM SmallAs.smallARemotecache AS g_0{code} * SRC CMD: {code:sql}SELECT g_0.stringNum FROM SmallAs.smallARemotecache AS g_0{code} * result 14 rows And query: {code:sql}SELECT BQT1.SmallA.StringNum FROM BQT1.SmallA WHERE BQT1.SmallA.StringNum = -22 ORDER BY StringNum{code} * Process Tree: {code:plain}LimitNode(0) output=[c.stringNum AS StringNum] limit 100 AccessNode(1) output=[c.stringNum AS StringNum] SELECT g_0.stringNum FROM SmallAs.smallARemotecache AS g_0 WHERE g_0.stringNum = '-22' ORDER BY g_0.stringNum{code} * SRC CMD: {code:sql}SELECT g_0.stringNum FROM SmallAs.smallARemotecache AS g_0 WHERE g_0.stringNum = '-22' ORDER BY g_0.stringNum{code} * result 1 row The first query should then return 15 rows instead of 0. Also the queries differ in a way they are processed, the first one is pushed down to infinispan, the other two are processed by teiid, which is probably a regression originally tracked here: TEIID-3424 The same cause introduces problems with similar queries: {code:sql}Select IntKey, StringKey From BQT1.SmallA WHERE NOT(StringKey > 10 AND IntKey < 47) ORDER BY IntKey{code} Which is processed as: * Process Tree: {code:plain}LimitNode(0) output=[c.intKey AS IntKey, c.stringKey AS StringKey] limit 100 AccessNode(1) output=[c.intKey AS IntKey, c.stringKey AS StringKey] SELECT g_0.intKey, g_0.stringKey FROM SmallAs.smallARemotecache AS g_0 WHERE (g_0.stringKey <= '10') OR (g_0.intKey >= 47) ORDER BY g_0.intKey{code}
