OData4 translator doesn't correctly translate LOCATE function to INDEXOF ------------------------------------------------------------------------ Key: TEIID-5277 URL: https://issues.jboss.org/browse/TEIID-5277 Project: Teiid Issue Type: Bug Components: OData Affects Versions: 8.12.11.6_4 Reporter: Jan Martiska Assignee: Steven Hawkins Suppose this query against an OData4-backed view: {noformat} SELECT STRINGKEY FROM BQT1.SmallA WHERE LOCATE('1', stringkey) = 1 {noformat} The WHERE clause gets translated into {noformat} filter=indexof('1',stringkey) eq 1 {noformat} There are two issues with this: - the arguments of the {{indexof}} function should be in the opposite order (the sought-after string goes second) - {{indexof}} function indexes characters in strings from 0 whereas {{LOCATE}} from 1, this needs to be taken into account The correct filter in this case should be: {noformat} filter=indexof(stringkey,'1') eq 0 {noformat} See http://docs.oasis-open.org/odata/odata/v4.0/odata-v4.0-part2-url-conventi...
