db2

问题 I am developing a simple web app that has 3 reports created on VS 2013, for some reason those reports run fine from developer mode, but when I publish the website they give me "Database logon failed" Error. What could be causing this? VS is installed on the same server that I am publishing the reports. I have created a local admin user with exactly the same info as the ODBC connection logon user for IIS authentication, but still no luck. below is my code: public partial class OpenWOsWebForm :

问题 I've posted this question on the new dba.stackexchange.com (please, let me know if I have to delete one). I'm working on a DB2 database, and as far as I can see regexp is not supported (without additional libraries). So I cannot implement something similar to what is explained in this article "Bringing the Power of Regular Expression Matching to SQL" Do you know if I can "emulate", with a SQL statement, a regular expression like this? ^[aofdmep]\{1\}[a-z]\{1\}[a-z0-9]\{4\}a[sidbfkfpo]\{1\}

问题 I need to convert Decimal to date. I have a decimal date field that contains data like this : 1,132,009.00 --1/13/2009 7,152,004.00 --7/15/2004 11,012,005.00 --11/01/2005 etc I would like it to read as xx/xx/xxxx . Is there anyway to do this with SQL commands or DB2 logic in a select statement? SELECT column1 from table1 ; 回答1: WITH x(decvalue) AS ( VALUES (DECIMAL(1132009.00)),(DECIMAL(7152004.00)),(DECIMAL(11012005.00)) ) SELECT CAST( LPAD( RTRIM( CHAR( INTEGER( decvalue/1000000 ))), 2, '0'

问题 I need to get the difference in days between two dates in DB2. I tried a couple of different queries but nothing seems to be working. So basically what i need to get is something like this. SELECT DAYS (CURRENT DATE) - DAYS (DATE(CHDLM)) FROM CHCART00 WHERE CHSTAT = '05'; I know that if I remove CHDLM and specify a date like '2012-02-20' it works but I need to be able to run this against that field in the table. I also try this query that was given to me by a friend by is not working either.
