the detailed optimization steps and data during the DML operation. First, let's look at a query optimization example. The following is the table creation statement in the experiment: CREATETABLEMCLAIM.T1_DMS( C11VARCHAR(10)NOTNULL, C12VARCHAR(15)NOTNULL, C13VARCHAR(20)NOTNULL, CONSTRAINTC11_PKPRIMARYKEY(C11))INDMS_Space; CREATETABLEMCLAIM.T2_DMS( C21VARCHAR(15)NOTNULL, C22VARCHAR(25)NOTNULL, C23VARCHAR(30)NOTNULL, CONSTRAINTC21_PKPRIMARYKEY(

Break can leave the program block of the current switch, for, while, and do, and advance to the next statement after the block, which is used primarily to interrupt the next case comparison in switch. It is used primarily to interrupt the current loop execution in for, while, and do.The Continue function is similar to break, which is used primarily for loops, except that break ends the execution of the block, and continue only ends the statement of the block after it, and jumps back to the begin
