With UR. If you are using v7 of the DB2 Client, specifying the With UR (Uncommitted Read) clause at the end of your SQL will give you a syntax error. This is because DB2 and/or AQT will have added the optimize clause at the end of your SQL; this is invalid syntax as the With UR needs to at the end of the SQL. To circumvent this, code your own optimize clause.

If you that option, DB2 will fetch the qualifying rows (including uncommitted rows i.e modified by someone else and not committed) In this case if that person gave ROLLBACK, the values you received are wrong. So you may be using with inconsistent data.

Let’s pretend you work at a large donut company, DiscoDonuts. You have a query to you run the following query against DB2. Typically you might use a tool such as DataStudio.

db2 "select id from dba.test1 group by id having count(id)>1 with ur" db2 "select ID FROM (select ID ,ROW_NUMBER() OVER(PARTITION BY ID) AS ROWNUM FROM DBA.TEST1) WHERE ROWNUM>1 WITH UR" As you can see both methods produced the desired output and I am sure there are other ways to do it using self joins etc. but these are the two basic ways to pull out the duplicates.

1、ur (Uncommited Read) 就是俗称 how long read (share) locks are held, except for UR which allows one to see updated but not committed data. Second, DB2 (unlike Oracle) only has one copy of the data.

Keep in mind, too, that the UR isolation level applies to read-only operations: SELECT, SELECT INTO, and FETCH from a read-only result table. Any application plan or package bound with an isolation level of UR will use uncommitted read functionality for any read-only SQL.

This means that whenever possible, DB2 avoids any access path that involves a sort. If you specify a value for n that is anything but 1, DB2 chooses an access path based on cost, and you won’t necessarily avoid sorts. DB2 Cursor builds a results table to hold all the rows retrieved by executing a SELECT statement. DB2 uses a cursor to make the rows, from the results table, available to the application program. A cursor identifies the current row of the results table. Use your DB2 expertise at DiscoDonuts.
