Insert records into table in SQL server
Is there a way in SQL SERVER(05 & 08) that I can insert records from an external file into a temp table? I do not have privilege to the database at all. Here is what i tried to do:
CREATE table #tem开发者_如何学编程p
(KEY_ID INT)
INSERT INTO #temp
SELECT 90883000
Ran #temp table with result:
KEY_ID
---------
90883000
It kind of works with just one record. How do I do if I have hundred records? Thanks a lot!!!
This just to show how to add multiple rows in a table.
CREATE table #temp(
KEY_ID integer
)
Declare @i as int
set @i = 1
WHILE (@i <= 10000)
BEGIN
insert into #temp values(@i)
set @i += 1
End
How about a table variable. I believe that the #temp need rights to the tempdb database. I believe that a table variable is used just like any other variable which is session based.
To declare a table variable:
DECLARE @ProductTotals TABLE
(
ProductID int,
Revenue money
)
Insert into a table variable:
INSERT INTO @ProductTotals (ProductID, Revenue)
SELECT ProductID, SUM(UnitPrice * Quantity)
FROM [Order Details]
GROUP BY ProductID
For importing files, you can use BULK IMPORT. Use this to get the data into your temp table, then you can run set based operations against it.
A more effective way of inserting a lot of rows.
INSERT INTO #temp
(KeyID)
SELECT TOP 1000 -- PUT YOUR QUANTITY HERE
IDENTITY(INT,1,1) AS N
FROM Master.dbo.SysColumns sc1,
Master.dbo.SysColumns sc2
If you're going to be using this a lot, just ask them to create you a TALLY TABLE.
This is how I usually do it if I have the values in a file somewhere. Inserting hundreds of records from flat text file into temp table. My example only has one column, but as long as the flat file is delimited somehow, you can do as many columns as needed. Need to make sure you put the text file in a directory you have access to.
IF OBJECT_ID('tempdb..#TempTable') IS NOT NULL DROP TABLE #TempTable
CREATE TABLE #TempTable(Col1 varchar(10)) --Specify temp-table name & columns
BULK INSERT #TempTable
FROM 'C:\FileName.txt' --Specify file path/name
WITH (
FIELDTERMINATOR = '\t',
ROWTERMINATOR = '\n'
);
GO
