问题 I want to know how many rows are going to be returned by this query: SELECT MONTH(DHSTMP), SUM(DHDLDY), SUM(DHBUDS), YEAR(DHSTMP) FROM DSHDAY WHERE DHSTMP BETWEEN '2009-07-26 00:00:00' AND '2011-03-09 23:59:59' GROUP BY YEAR(DHSTMP), MONTH(DHSTMP) ORDER BY YEAR(DHSTMP), MONTH(DHSTMP) So I tried: SELECT COUNT(*) FROM DSHDAY WHERE DHSTMP BETWEEN '2009-07-26 00:00:00' AND '2011-03-09 23:59:59' GROUP BY YEAR(DHSTMP), MONTH(DHSTMP) But it tells me how many rows for each group.

Date value - 2018-05-21 17:33:56.2463440 little bit of query - Snapshot from SSIS " SELECT LPAD(i.abc, 13, '0') AS abc, LPAD(i.abc,9,'0') AS abc, b.abc, i.abc, i.abc, i.abc, i.abc, i.abc, i.abc, i.abc, i.abc, sd.abc FROM abc.abci LEFT OUTER JOIN abc.abc b ON i.abc= b.abc, abc.abc f INNER JOIN abc.abc v ON i.abc= v.abc ,abc.abc md, abc.abc sd WHERE i.abc= 'A' AND i.abc=

问题 I have a very similar problem to the question asked here: Merge duplicate temporal records in database The difference here is, that I need the end date to be an actual date instead of NULL. So given the following data: EmployeeId StartDate EndDate Column1 Column2 1000 2009/05/01 2010/04/30 X Y 1000 2010/05/01 2011/04/30 X Y 1000 2011/05/01 2012/04/30 X X 1000 2012/05/01 2013/04/30 X Y 1000 2013/05/01 2014/04/30 X X 1000 2014/05/01 2014/06/01 X X The desired result is: EmployeeId StartDate

问题 I am working with some SQL queries on DB2. Is it possible to select all the columns in a table and also specify certain conditions using the "as" keyword within that select statement? For example, is this query possible: select *, col1 + col2 as sum1, col3 - col4 as dif1 from table; Whenever I attempt this, I am getting the SQL0104 error and it is saying "Token , was not valid. Valid tokens: FROM INTO". Thank you for your help. EDIT: This query is running inside an SQLRPGLE program on an

问题 Has anyone ever try to use DB2 import from within a Perl program? My application is inserting 10 million of rows and apparently connecting using DBI and doing the insert row by row takes forever. DB2 import/load from the command line works great, however is there a better way rather than to call a system call from the Perl program to invoke: use IPC::System::Simple qw( systemx ); use autodie; systemx( "db2 connect ..." ); systemx( "db2 import ..." ); etc? thanks! 回答1: I have actually had

问题 I have the following query which works nice when running directly against DB2: String sql = "select slutt_dato + 1 day as tDato from klv80201 " + "union " + "select fra_dato as tDato from klv12101 where avtalenr = :avtalenr and kundenr = :kundenr " + "union " + "select fra_dato as tDato from klv12401 where avtalenr = :avtalenr and kundenr = :kundenr and MEDLEMSTATU < '32' " + "order by tDato desc fetch first 1 rows only;"; But when I run it through a test with H2 as database with the

问题 Hi I have this function: CREATE or replace FUNCTION Tablereturn (SWITCHER INTEGER) RETURNS TABLE (Test CHAR(9), tester INTEGER ) LANGUAGE SQL CONTAINS SQL DETERMINISTIC NO EXTERNAL ACTION BEGIN DECLARE SELECT1, SELECT2 VARCHAR(1024); set select1 ='SELECT TEST, TESTER FROM TESTTAB'; set select2 ='SELECT DUMMY, JAR, BRAND FROM TESTTAB'; IF (SWITCHER = '1') THEN return select1; ELSEIF (SWITCHER = '2') THEN return select2; END IF; RETURN TABLE; END@ Calling would be select TEST from TABLE

问题 If we have created a view on an existing DB2 table and then drop the table. What will happen to the view ? 回答1: The view becomes invalid/inoperative. Attempts to select from it will fail. To try it: create table TEST_TABLE ( TEST_COL INTEGER ); INSERT INTO TEST_TABLE VALUES(1); SELECT * FROM TEST_TABLE; create view TEST_VIEW AS SELECT * FROM TEST_TABLE; SELECT * FROM TEST_VIEW; DROP TABLE TEST_TABLE; SELECT * FROM TEST_VIEW; The last statement gives the error: [IBM][CLI Driver][DB2/NT]
