db2

问题 I have created a DB2 database, and I'm trying to create a new user. Here the steps I made : - Creating an OS (Linux) user with root account (useradd myuser) - Giving a password to the new user (passwd myuser) - On IBM Data Studio, I added a new user and grant him connect to the database But on Linux, with the user which owns the instance, I tried to connect to the database with the new user (db2 connect to MYDB user myuser), I've the following : SQL30082N Security processing failed with

I received some helped here with the function TRANSLATE to determine if Left contained records that began with three letters: select pat.f1, hos.hpid, hos.hpcd from patall3 pat join hospidl1 hos on pat.f1=hos.hpacct where TRANSLATE( LEFT( hos.hpid, 3 ), 'AAAAAAAAAAAAAAAAAAAAAAAAA', 'BCDEFGHIJKLMNOPQRSTUVWXYZ' ) <> 'AAA' order by pat.f1; But as you can see in my screenshot, there are records that remain, presumably

问题 I need to get a userstamp into a table and have not managed to figure out how the GENERATED FOR EACH ROW ON UPDATE AS statement works with the SESSION_USER variable in DB2 10.5 (LUW). Managed to get an implementation working using a function which has a fake variable for forcing the evaluation in update statements: CREATE OR REPLACE FUNCTION XXX.CURRENT_USER( tmp varchar(128)) SPECIFIC xxx.XXX_CURRENT_USER RETURNS VARCHAR(128) CONTAINS SQL DETERMINISTIC NO EXTERNAL ACTION BEGIN RETURN session

问题 So what I want to do is store images inside a database and not on the file system. And after storing them, i want to detect whether the image is coloured or black& white, crop the image to a size i specify later, etc. Also, I don't want to get the image manipulation done via the overlying application like Java, C# or PhP as my database may be indirectly accessed without using any overlying application. For storing images, I checked the following DBMS's: Oracle Multimedia(formerly Intermedia)

When I open Data Studio, I only see the instance called DB2 but the inst2 instance doesn't appear. How do I get my second instance and its databases to appear so that I can work with them? I've tried refreshing the Administration view and even stopping and restarting Data Studio but the second

问题 I have slimmed down the query to remove potential complications, in addition I have verified that the fields are correct. DB2 UDB zSeries V7 is my db2 version.
