Oracle COALESCE function syntax is COALESCE (expression 1, expression 2 ,..., expression n), n> = 2. The function of this expression is to return the first non-null expression. If both are null, a null value is returned. Note: All expressions must be of the same type or can be converted to the same type.

The size of each NALU varies depending on the data volume it contains. In an IP network, when the IP packet size to be transmitted exceeds the maximum transmission unit MTU (maximum transmission unit), IP fragmentation occurs. The maximum size of IP messages (MTU) that can be transmitted over the Ethernet is 1500 bytes. If the IP packet sent is greater than MTU, the
