Problem description: | |
Please ensure that the defect Project is correct, the Abstract is descriptive and follows all standards set out by your organization, team and sub-team, and the Build Level and Environment fields in the Testing tab are complete. Also, please include information about the Install image used if that is what was used for testing). 1. Problem description (This section should include a description of the failure you are opening this defect for, including all symptoms you think would be interesting to Development and failing routine name and trace point (if available), SQLCODE/failure during the operation, and testcase name (if applicable). If you have been able to isolate the fault yourself, a detailed explanation of the fault and its location should be included here.) Incorrect result when using A VIEW or WITH clause containing a FETCH FIRST n ROWS clause Multiple references to that VIEW or WITH clause from when using ANSI join syntax; 2. Operating system and level: ENV: AIX DB21085I This instance or install (instance name, where applicable: "mdsinst1") uses "64" bits and DB2 code release "SQL10054" with level identifier "0605010E". Informational tokens are "DB2 v10.5.0.4", "special_32990", "IP23616_32990", and Fix Pack "4". Product is installed at "/opt/IBM/db2/V10.5.4_sp32990". 3. Client, server, and gateway information a. Client information, if applicable Project: Build Level: Environment (including Platform and bitness): b. Gateway information, if applicable Project: Build Level: Environment (including Platform and bitness): c. Server information, if applicable Project: Build Level: Environment (including Platform and bitness): 4. System setup (For example, if your database is partitioned, this is where this information should be included. Provide clearcase view name, and contents of db2nodes.cfg file, including catalog, coordinator node information. Also which machine name has which node number(s) for DPF.) 5. Diagnostic information (This section should include applicable db2diag.log entries, stack traces, lineofcode tool output, and formatted dump files. Also include any other FODC or PD tool output that helped you or will help Development diagnose the failure you're opening this defect for. Include the location of all files not attached but referenced by this defect.) 6. How to reproduce the problem (Include the name of the bucket and snippet of existing or planned test unit that exposed the failure described above. A "repro" should be as small as possible. Also, include the degree of difficulty of the repro. A repro is Easy if it can be done on demand, Medium if it can be done after several attempts, and Hard if it is not possible.) Problem can be reproduce with following SQL: ============= create table temp1(tpp_val date,desc varchar(20)); create table temp2(tpp_val date,dsb_nbr varchar(20),usr_nbr varchar(20),chk_flag char(1)); create table temp3(tpp_val date,dsb_nbr varchar(20),usr_nbr varchar(20)); create table temp4(tpp_val date,spp_cod varchar(3),spp_val varchar(3)); insert into temp1 select (date('2014-01-01')+row_number() over(order by tableid) days),substr(tabname,1,20) from syscat.tables; insert into temp2 select (date('2014-01-01')+row_number() over(order by tableid) days),char(row_number() over(order by tableid)),char(row_number() over(order by tableid)),'Y' from syscat.tables; insert into temp3 select (date('2014-01-01')+row_number() over(order by tableid) days),char(row_number() over(order by tableid)),char(row_number() over(order by tableid)) from syscat.tables; insert into temp4 select (date('2014-01-01')+row_number() over(order by tableid) days),char(row_number() over(order by tableid)),char(row_number() over(order by tableid)) from syscat.tables; with tmp_tpp(tpp_val) as (select distinct tpp_val from temp1 where tpp_val <='2014-11-30' order by tpp_val desc fetch first 33 rows only),tmp_rptchksts(tpp_val,chk_flg) as (select a.tpp_val,'Y' from temp2 a inner join tmp_tpp t on a.tpp_val=t.tpp_val left join temp3 b on a.dsb_nbr=b.dsb_nbr ),tmp_dta as (select a.tpp_val,spp_cod,spp_val from temp4 a inner join tmp_rptchksts r on a.tpp_val=r.tpp_val where a.spp_cod is not null and a.spp_val is not null) select a.tpp_val as rowseq,b.spp_cod from tmp_tpp a left join tmp_dta b on a.tpp_val=b.tpp_val order by rowseq asc with ur; ===================== 7. Did anything in particular seem to cause this problem? 8. Is this problem a regression? If so, please provide details on the last successful build level similar to (3) above. | |
