sql with ur

"WITH UR" in SQL stands for "WITH UNCOMMITTED READ". It is an optional clause that can be added to a SELECT statement to indicate that the query should use uncommitted data. This means that the query will read data that has been modified by another transaction but not yet committed, which can result in dirty reads.

For example, the following SQL statement uses the "WITH UR" clause to select all rows from the "customers" table using uncommitted data:

SELECT *
FROM customers WITH UR;

By default, SQL uses "WITH CS" (WITH CURRENTLY COMMITTED) which means that the query will only read data that has been committed. Adding "WITH UR" can be useful in certain scenarios, such as when you need to quickly view data that is being updated frequently by other transactions. However, it should be used with caution as it can lead to inconsistent or incorrect results in certain cases.
