MySQL 中使用 DROP PROCEDURE 语句来删除存储过程;使用 DROP FUNCTION 语句来删除存储函数。 语法为: DROP {PROCEDURE | FUNCTION} [IF EXISTS] sp_name IF EXISTS 子句是 MySQL 的扩展。如果过程或功能不存在,则可以防止发生错误。 delimiter delimiter 是MYSQL 分隔

The function coalesce can be used to replace zero values created due to an external join with other values or the result of expressions. The syntax check is performed in strict mode for Release 7.40, SP05 in the following cases: Not
The functioncoalescecan be used to prevent null values in the results set. A cross join behaves like an inner or outer join whoseONcondition is always true. A cross join with aWHEREcondition has the same result as an inner join with an identicalONcondition. Unlike the inner join, in a ...
