Here's an example and syntax for using the CASE expression in Oracle: In Oracle, the CASE expression allows you to add conditional logic to your queries. You can use the CASE expression to perform different operations based on a set of conditions. Here's the syntax for using the CASE expression in Oracle: sql CASE expression WHEN condition1 THEN result1 WHEN condition2 THEN result2 ... ELSE default_result END here's another example of using the CASE expression in Oracle: Suppose you have a table orders with columns order_id , order_date , total_amount , and discount . You want to create a new column discounted_total which will show the total amount after applying the discount, and if no discount is applied, it will show the regular total amount. Here's how you can achieve this using the CASE expression: vbnet SELECT order_id, order_date, total_amount, discount, CASE WHEN discount IS NULL THEN total_amount ELS

Here's how to do it: Using user_tables view: sql SELECT table_name FROM user_tables; This will give you a list of all tables owned by the current user. Using all_tables view: sql SELECT owner, table_name FROM all_tables; This will give you a list of all tables that you have access to. If you are querying as a privileged user, you will get a list of all tables in the database. Note that in both cases, the table names are returned in uppercase by default. If you want to see the names in their original case, you can use double quotes around the table name, like this: sql SELECT table_name FROM user_tables WHERE table_name = "MyTable"; Also, keep in mind that if you are querying a remote database, you will need to prefix the table name wi

This clause specifies the number of rows that should be returned from the result set after sorting. Here's an example query: sql SELECT column1, column2, column3 FROM your_table ORDER BY column1 FETCH FIRST 10 ROWS ONLY ; In this example, the query will return the first 10 rows of the result set after sorting by "column1". You can adjust the number of rows returned by changing the number after the "FETCH FIRST" clause.

  This error message suggests that the maximum number of nested groups has been exceeded, and as a result, a member could not be retrieved from an entry DN. It also indicates that there might be a circular definition that is causing this issue. In Oracle, there is a limit on the number of nested groups that can exist, which is set to a default value of 50. This limit is in place to prevent infinite loops and circular references, which can cause performance issues and potentially crash the system. When this limit is exceeded, you will receive the error message you mentioned. To resolve this issue, you can try reducing the number of nested groups or reorganizing the groups in a way that eliminates any circular references. You can also increase the maximum number of nested groups allowed by modifying the relevant configuration parameters in your Oracle system. Additionally, you can try reviewing the LDAP configuration and checking for any circular references in the group membership. Remov
