Label:In MySQL, specific exceptions require specific processing. These exceptions can be linked to errors, as well as general process control in subroutines. Defining an exception is a prior definition of the problem encountered during the execution of the program, and exception handling defines how it should be handled when a problem is encountered, and ensures that the stored procedure or function can continue to execute when it encounters an error or a warning.1 Exception Definition 1.1 synta

is not suitable for addressable memory space. (We'll talk in the back to addressable memory.) This means that DB2 cannot start the database because a database must have at least one buffer pool. If the database does not start, you cannot connect to the database, and you cannot change the size of the buffer pool. For this reason, DB2 pre-allocated 4 such small buffer pools. This way, once the primary buffer pool fails to start, DB2 can also use these small buffer pools to start the database. (In

MySQL defines the exception and exception handling methods, and MySQL defines the handling methods In MySQL, specific exceptions must be handled. These exceptions can be associated with errors and general process control in subprograms. Defining exceptions is a problem encountered during the execution of the program in advance.
