没错.所以我在 MySQL 数据库中创建了一个存储过程,它恰好使用了 SUBSTRING.
Right. So I've created a stored procedure in a MySQL DB which happens to use SUBSTRING.
通过查询运行该过程给了我:
Running the procedure via a query gives me:
SQL 错误 1630:函数 mydatabase.SUBSTRING 不存在
SQL Error 1630: Function mydatabase.SUBSTRING does not exist
请原谅?
Substring
的方法调用后第一个括号前有空格吗?
Is there a space after the method call to Substring
before the first parenthesis?
它出现在第 40 行:
It appears on Line 40:
IF i > 1 AND j > 1 AND (s1_char = SUBSTRING (s2, j - 1, 1))
即确保
select substring(CustomerName, 1, 4) AS CustName from MyTable;
代替:
select substring (CustomerName, 1, 4) AS CustName from MyTable;
