Hi
I have a temporary table with one of the column as -
RowID int identity(1,1) not null
Now when i want to insert into this table using a Select query, it gives error -
"The select list for the INSERT statement contains fewer items than the insert list. The number of SELECT values must match the number of INSERT columns."
Create Table #temp
(RowID int identity(1,1) not null,
MyID int not null,
MyName varchar(50) not null
)
Insert into #temp (RowID, MyID, MyName)
Select 1, 'Name'
select *
from #temp
drop table #temp1
Is there another way of doing this. And why does this not work?

Create Table #temp
(RowID int identity(1,1) not null,
MyID int not null,
MyName varchar(50) not null
)
Insert into #temp (RowID, MyID, MyName)
Select 1, 'Name'

Should read Insert into #temp (MyID, MyName) as you have listed 3 fields to insert but only entered 2 fields, as you are using an identity field you need not enter a value for this.

I just realized that. 🙂

Thanks for the help.

There's an alternative syntax which you may find more intuitive:

SELECT IDENTITY(int, 1, 1) AS RowID, ...

INTO #temp

FROM ...

If the FROM table ALSO have identity Column then what we do ?

I am Facing this Problem ..

SELECT IDENTITY(int, 1, 1) AS 'RowID',* ,ROW_NUMBER() OVER(PARTITION BY UID ORDER BY ID ) AS RN,ROW_NUMBER() OVER(PARTITION BY UID ORDER BY ID)-1 AS RNL

INTO #temp

FROM Temp1

RowId--->Identity IN #temp

ID------->Identity IN Temp1

Here Iam Getting The Error like

Msg 8108, Level 16, State 1, Line 3

Cannot add identity column, using the SELECT INTO statement, to table '#temp', which already has column 'ID' that inherits the identity property.

you are facing this Issue because of (*). when you do the following :

SELECT * INTO TABLE2 FROM TABLE1.

and an identity column exists in it, that particular identity column will be automatically inherit in TABLE2.

so if you want to avoid this issue, just used the column which you required something like this

SELECT IDENTITY(INT,1,1) AS RowID, Col1,Col2

INTO TABLE2

FROM TABLE1

Remove the identity property by casting:

DROP TABLE #ExistingTable

CREATE TABLE #ExistingTable (ExistingID int identity(1,1), blah VARCHAR(20))

INSERT INTO #ExistingTable (blah) VALUES ('first row'), ('second row'),('third row')

SELECT * FROM #ExistingTable

DROP TABLE #Temp

SELECT IDENTITY(int,1,1) AS ReplacementID, ExistingID = CAST(ExistingID AS INT), blah

INTO #Temp

FROM #ExistingTable

SELECT * FROM #Temp

You can also insert explicit values into an IDENTITY column by using SET IDENTITY_INSERT

ON.
