HANA translator : incorrect pushdown of DAYOFWEEK function ---------------------------------------------------------- Key: TEIID-4224 URL: https://issues.jboss.org/browse/TEIID-4224 Project: Teiid Issue Type: Bug Components: Misc. Connectors Affects Versions: 8.12.5 Reporter: Jan Stastny Assignee: Steven Hawkins Teiid's DAYOFWEEK function: {code:plain} DAYOFWEEK(x) Return day of week (Sunday=1, Saturday=7) {code} is pushed down as: {code:plain} dayname(g_0."DATEVALUE") {code} but this function returns string representation of the day. More appropriate would be to push DAYOFWEEK as WEEKDAY function, but the returned value has to be adapted to Teiid's representation (Sunday=1 and Saturday=7, vs. HANA's Monday=0,Sunday=6). So the solution would be to push: {code:sql} MOD((WEEKDAY(datevalue)+1),7)+1 {code}
