I am trying to select data containing four percentage signs in a row. How can I escape the percentage signs so my LIKE condition works? Thanks Use @% with the escape character clause: select * from tbl where fld like '%@%%' escape '@' This will search for all records that contain the "%" character in the fld column. DB2/z has a slightly different format: select * from tbl where fld like {escape '@'} '%@%%' Obviously, you'll need to choose your escape character carefully so it won't interfere with the rest of your string but this is relatively easy for static strings. Dynamically built strings

I am getting this JDBC exception. I googled it but the explanation was very abstract.

The errror that DB2 gives should point what

I would like to test a DB2 stored procedure running on an AS400 system. I have the IBM System i Access for Windows installed and can run SQL commands against the DB2 database. My question is: What is the syntax to execute a stored procedure that takes in a parameter and returns a result as an output parameter and print the value to the screen? Just to clarify: I am not asking how to call the proc in code. I want to execute the proc and see the results in the gui tool (which is similar to SQL Enterprise Manager). use the keyword call and pass in the parameters. call myStoredProc(parm1, parm2, ?

操作DB2 下 sequence seqName db2数据库一般seq还是比较大的，但是程序在调用的时候还是不可避免的有一些bug， 下面是对于seq一些简单的操作，也作为工作的一些记录 1、命令行取sequence seqName的下一个值： db2 "values next value for seqName" 2、命令行重置sequence seqName： db2 "alter sequence seqName restart"，重置后的值默认为创建SEQUENCE时的MINVALUE 3、命令行以指定值1重置sequence seqName： db2 "alter sequence seqName restart with 1" 4、命令行重置表 table_name.columnName的IDENTITY字段初始值为1： db2 "ALTER TABLE table_name.columnName ALTER COLUMN identity RESTART WITH 1" 来源： https://my.oschina.net/feixuewuhen/blog/3131192

Considering the following code blocks, why does call to HQL work but call to delete() not work? As a background, I'm using NHibernate over IBM.Data.DB2.Iseries driver. Come to find out, journaling on the AS400 is turned off so I can't use transactions. I'm not the AS400 admin or know anything about it so I don't know if having journaling turned off (not opening transactions) is causing this problem or not. Do I absolutely need the ability to open transactions if I'm calling Delete() or other NHibernate functions? //This Does not work - no error and no deletes public static void Delete(Object
