'3" Screw', '"', 'in') however I also have to take into account replace('Label "Stop"', '"', ''). So I was able to build an SQL Function for this but I can't find out how to build the MYSQL function. The SQL Function is what follows. How do I translate this to MYSQL...
MySQL doesn't support DDL in transactions, so I would like to have MySQL support a ALTER PROCEDURE/FUNCTION <NEW BODY TEXT> command (i.e. SQL Server), or a CREATE OR REPLACE PROCEDURE/FUNCTION command (i.e. Oracle and PostgreSQL). Although if DDL in transaction support would be added,...
在mysql 中show create table 可以直接查询表的create sql 语句,在postgreSQL 没有这个命令,所以通过function 来实现,代码如下: 前提 定义一个公用的函数:findattname CREATE OR REPLACE FUNCTION findattname(namespace character varying, tablename character varying, ctype character varying) RETURNS character varying...
根据报错，语句中存在中文字符，根据报错提示，查看对应位置是否存在中文字符。

分享一个MySQL自定义函数CREATE FUNCTION的实例。 mysql> delimiter $$ mysql> CREATE FUNCTION myFunction -> (in_string VARCHAR(255), -> in_find_str VARCHAR(20), -> in_repl_str VARCHAR(20)) -> -> RETURNS VARCHAR(255) -> BEGIN -> DECLARE l_new_string VARCHAR(255); ...
MySQL checks view privileges like this: Example: A view might depend on a stored function, and that function might invoke other stored routines. For example, the following view invokes a stored functionf(): Suppose thatf()contains a statement such as this: ...
mysql>mysql> delimiter ;mysql>selectmyFunction('ABC','A','Z');+---+| myFunction('ABC','A','Z') |+---+| ZBC |+---+1 rowinset(0.00 sec)mysql>dropfunctionmyFunction;Query OK, 0rowsaffected (0.00 sec)
MySQL中的CREATE FUNCTION授权 在MySQL中,CREATE FUNCTION是用于创建用户自定义函数的语句。用户自定义函数是一组SQL语句的集合,可以在MySQL中调用和使用。为了保证数据库的安全性和正确性,我们需要对CREATE FUNCTION语句进行授权,以限制用户对函数的创建和修改。
SELECT my_function(1); 3、修改函数 MySQL不支持直接修改函数,你需要先删除旧函数,然后重新创建新函数。 4、删除函数 DROP FUNCTION my_function; 创建存储过程(CREATE PROCEDURE) 存储过程是一组为了完成特定功能的SQL语句集合,下面是一个创建存储过程的示例。
