SQL for DbFunctions.CreateDateTime does not work ------------------------------------------------
Key: DNET-937 URL: http://tracker.firebirdsql.org/browse/DNET-937 Project: .NET Data provider Issue Type: Bug Components: Entity Framework Affects Versions: 7.5.0.0 Reporter: Daniel Richter Assignee: Jiri Cincura Calling the DbFunctions method CreateDateTime(int? year,int? month,int? day,int? hour,int? minute,double? second) generates SQL code that is not executable. The SQL generating method (HandleCanonicalFunctionCreateDateTime) assumes that all parameters are constants and all parameters are not null. Additionally, the parameter for seconds is of type double so the generated SQL contains a CAST inside a timestamp literal (so it won't work even if all parameters a non-null constants). The call DbFunctions.CreateDateTime(2020,3,19,12,0,0) is translated to CAST('2020-3-19 12:0:CAST(0 AS DOUBLE PRECISION)' AS TIMESTAMP) The call DbFunctions.CreateDateTime(2020,3,19,null,null,null) is translated to CAST('2020-3-19 NULL:NULL:NULL' AS TIMESTAMP) The call DbFunctions.CreateDateTime(c.BirthYear,1,1,null,null,null) is translated to CAST('"C"."BIRTHYEAR"-1-1 NULL:NULL:NULL' AS TIMESTAMP) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tracker.firebirdsql.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira _______________________________________________ Firebird-net-provider mailing list Firebird-net-provider@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/firebird-net-provider
