Sql将数据从一个表插入另一个表

Question

我有一个疑问。我需要SQL SERVER的语法 - 如何将数据从一个表插入另一个表？

Answer 1

使用INSERT INTO..SELECT声明

INSERT INTO table2 (col1,...)
SELECT col1,...
FROM table1

• SQLFiddle Demo (different records but have same thought)

Answer 2

Insert INTO Table1 (UserName) (Select UName From Table2 b Where Table1.EID = b.EID)

但显示消息：

The multi-part identifier "Table1.EID" could not be bound.
