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

您的语法不太正确:您需要按顺序在INTO之前列出字段，并在以下列出相应的目标变量:

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
