[英]Alter dynamically created table in ms sql
Suppose, I have a temp table #Temp1 with say two columns Name and Nationality as Varchar(50) datatypes and the table has some records. 假设我有一个临时表#Temp1,其中说两列Name和Nationality为Varchar(50)数据类型,并且该表具有一些记录。 I create another temp table from this table(#temp1) as #Temp2.
我从该表(#temp1)创建另一个临时表作为#Temp2。 Now I wish to add another couple of column to that temp table say PhoneNo as Int and Gender as Char datatypes.
现在,我想在该临时表中添加另外几列,例如将PhoneNo表示为Int并将Gender表示为Char数据类型。 How do I achieve that?
我该如何实现?
Begin Tran
Create table #Temp1(
Name Varchar(50),
Nationality Varchar(50)
);
Insert Into #Temp1 (Name, Nationality) Values ('Jayaraj','Indian');
Select Identity(Int,1,1) SlNo, Name Into #Temp2
From #Temp1 Order By Nationality
-- Now the actual issue begins. I wish to alter the #Temp2 table.
-- So I try to alter the table, to add column Phone and Gender
Alter Table #Temp2
Add(
Phone Int,
Gender Char
);
Select * from #Temp2
-- Upon Executing I get this error :
/*
Msg 102, Level 15, State 1, Line 16
Incorrect syntax near '('.
*/
Rollback
Thanks for helping.. 感谢您的帮助。
You can do this: 你可以这样做:
Alter Table #Temp2
Add Phone Int, Gender Char
Just have to remove "()". 只需删除“()”即可。 :-)
