我可以在MySQL的同一选择查询中将多个列选择到多个变量中吗?
Can I SELECT multiple columns into multiple variables within the same select query in MySQL?
例如:
DECLARE iId INT(20);
DECLARE dCreate DATETIME;
SELECT Id INTO iId, dateCreated INTO dCreate
FROM products
WHERE pName=iName;
正确的语法是什么?
推荐答案
Your syntax isn't quite right: you need to list the fields in order before the INTO, and the corresponding target variables after:
SELECT Id, dateCreated
INTO iId, dCreate
FROM products
WHERE pName = iName
