Sometimes, we need to link the data obtained from different columns. Each database provides methods to achieve this purpose:MySQL: CONCAT ()
Oracle: CONCAT (), |
SQL Server: +
The CONCAT () syntax is as follows:
CONCAT (String 1, string 2, string 3,...): concatenates string 1, string 2, string 3, and other words.
Note that Oracle CONCAT () only supports two parameters;
In other words, only two strings can be connecte

(2) Data Guard broker does not support cascaded destinations.
Configure Cascaded Destination
(1) Select a physical standby database as the cascading standby database.
(2) set the FAL_SERVER parameter in cascading standby database to primary database or other standby databases that directly receive redo data from primary database.
(3) set the LOG_ARCHIVE_DEST_n parameter in cascading standby database to specify cascaded destination and other valid paramet
