With it, from the perfect traction map Mobile mode is a step away. There is only one last link left, everybody refuels.

course, the cursor will automatically close at the end of the stored procedure (execution to end), even if it is not manually closed:CLOSE ordernumbers;Next is the fetch data, each fetch is the next line! Can be combined with the above several knowledge points to do a small experiment, the above is the experimental table:DROP PROCEDURE IF EXISTSHello;delimiter//CREATE PROCEDUREHello ()BEGIN --declaring local variables for temporary storage of FETCH
