SQL and the "WITH UR" clause

I need to know this for clarity sake.

On another thread, an expert posted that I should use the "WITH UR" clause in my select statement

Where UR equals Uncommitted Read

(Note this was from an issue stating that my SELECT SUM(BAL) FROM ACCT" was not issuing the correct summation, so there may be uncommitted  records within the table.

My question is:  Will the following command work in BOTH the CLP and the JDBC cclient connection.


Open in new window

 In other words will the JDBC client connection be able to see the unread records as well as the CLP with this command ?  (I would think there is a possiblitliy that the CLP could see the unread, but not the JDBC, but I really dont know how this works)

I did not suggest you always use  "with ur". Please make sure you understand what that means.
Reading uncommited data means that your program reads data that is in the process of being changed. If another program (session) is changing data that another reads and then the change is rolled back due to some reason, then the session reading the data will have read wrong status of the data.
