請教數據庫專家個初級問題,這個用t-sql怎麽寫?
if I create a table as below:
CREATE TABLE table1(
column1 varchar(50),
column2 varchar(50),
column3 varchar(50),
column4 varchar(50));
what is the code for adding the column named “columnX” after column2 to the table shown above?
ALTER TABLE table1 ADD columnX varchar(50)
可以add a new column,但怎麽加到指定位置呢(after column2)?
