Comments on: SQL SERVER – Insert Multiple Records Using One Insert Statement – Use of UNION ALL

Remove the last “UNION ALL”.
If you look at the example, there’s no “UNION ALL” after the final entry. I haven’t tried it but this is my guess as to why you might be getting errors.

This page really great…

Please give me a script that once i entered four digit numbers i can insert it to the database as many as i can instead of inserting it one by one.. i have here the script but i dont know how to insert it even 100 times in one click.

$sqllucky = “INSERT INTO lucky (userid,lucky1,lucky2,lucky3,lucky4,ldate) VALUES (‘$userid’,'$lucky1′,’$lucky2′,’$lucky3′,’$lucky4′,now())”;
$luckyresult = connect($sqllucky);

that snippet can inserted one by one what if i want to insert 10 times…please help me…

Wow, in my tests the 2008 method is actually about 2 x slower than the Table Variable method. AND it is limited to 1000 rows.

Pinal,

Hmmm I just noticed the update you wrote at the top.
(ie 2008 method of Row Construction).

I wonder how my method compares in performance.

I might give it some testing.

FYI – I have done extensive research regarding this original post, and according to my research the fastest way to insert bulk data via SQL is to use a Table Variable as follows…

DECLARE @TblVar table (FirstCol nvarchar(50), SecondCol int)

INSERT INTO @TblVar
VALUES (‘First’,1);

INSERT INTO @TblVar
VALUES (‘Second’,2);

INSERT INTO MyTable (FirstCol, SecondCol)
SELECT * from @TblVar

Sure it is not a single statement. But… it was about 4 times faster than the UNION ALL method.

For large numbers of records I got better performance by grouping 1000 records at a time (ie repeating the SQL above for every 1000 records). I ran each group of 1000 records as a separate script.

I welcome any feedback…

Select AcType, MainCode, Balance from Master where AcType between ’01′ and ’07′ and Balance>100000

Select AcType, “~”, SUM(Balance) from Master where AcType between ’01′ and ’07′ and Balance>100000

Sorry, I should work, I have check my error msg and it is a primary key violation.
Dear Reader,
you can use either Pinal’s process ro my process as you like.

Hi Pinal,

I have tried to use you way of inserting multiple records.
INSERT INTO MyTable (FirstCol, SecondCol)
SELECT ‘First’ ,1
UNION ALL
SELECT ‘Second’ ,2
UNION ALL
SELECT ‘Third’ ,3
UNION ALL
SELECT ‘Fourth’ ,4
UNION ALL
SELECT ‘Fifth’ ,5

Msg 2627, Level 14, State 1, Line 1
Violation of PRIMARY KEY constraint ‘PK_tableName’. Cannot insert duplicate key in object ‘tableName’.
The statement has been terminated.

I usually use excel formula to create insert into statement. It helps me to upload more than a millions of records in a minute. Those who do insertion in the database quite frequently, they can use my technique that use excel formula.

this is actually a MUCH faster method:

INSERT INTO MyTable (FirstCol, SecondCol)
VALUES (‘First’,1),
(‘Second’,2),
(‘Third’,3),
(‘Fourth’,4),
(‘Fifth’,5);

First result is created and last it is ordered. But there is no gurantee that the order by work correctly. You should always use order by clause when using select statement
