问题 I need to get info about user connected to my DB2. How can I get (if I can) computer name/login or IP of that user?

问题 I have been following this tutorial: "Build and deploy a REST API on IBM Bluemix with PHP and MySQL." The tutorial uses mySQL. I want to use the SQL Database service, which uses DB2, I think. The tutorial implements a REST API. When I try making a REST call using these links I get nothing in return. For example, here's how I use my Bluemix application's REST API: http://products-api-db2-test2-5.mybluemix.net/v1/products.json http://products-api-db2-test2-5.mybluemix.net/v1/products I have

问题 I'm running DB2 for i, V7R2 TR3. I was told opening a cursor provides a lot of overhead and should be avoided whenever possible.

This is my Stored Procedure: BEGIN DECLARE STMT1 VARCHAR ( 500 ) ; SET STMT1 = 'SELECT SUBSTR (''' || TRIM(ITEM) || ''' , ( LENGTH ( TRIM ( PREFIX ) ) + 1 ) , ( 20 - LENGTH ( TRIM ( PREFIX ) ) ) ) ' || 'FROM MYLIB.MYTABLE ' || 'WHERE

问题 I want to alter a db2 identity to cycle cache and to make it (re)start with a specific value, something like: ALTER TABLE ALTER COLUMN SET GENERATED ALWAYS AS IDENTITY (CYCLE CACHE 100) RESTART WITH 32323 Is there a way of doing this so that I can add cycle cache as well as make it restart from a specific number? 回答1: What error are you seeing?

问题 We have developed an application which runs on the mainframe (z/OS), and it uses CAF, the Call Attach Facility, to talk to DB2/z for storing its data. Those customers which already have DB2/z (and hence have to pay for it regardless) are not concerned, but there are others who want to use our application without incurring the expense of the database as well. They have expressed a desire to have our product not use DB2/z, due to the expense. Under z/OS, the licence fees for DB2 are rather high
