I have the following code in one of my Sql (2008) Stored Procs which executes perfectly fine:
CREATE PROCEDURE [dbo].[Item_AddItem]
@CustomerId uniqueidentifier,
@Description nvarchar(100),
@Type int,
@Username nvarchar(100),
AS
BEGIN
DECLARE @TopRelatedItemId uniqueidentifier;
SET @TopRelatedItemId =
(
SELECT top(1) RelatedItemId
FROM RelatedItems
WHERE CustomerId = @CustomerId
)
DECLARE @TempItem TABLE
(
ItemId uniqueidentifier,
CustomerId uniqueidentifier,
Description nvarchar(100),
Type int,
Username nvarchar(100),
TimeStamp datetime
);
INSERT INTO Item
OUTPUT INSERTED.* INTO @TempItem
SELECT NEWID(), @CustomerId, @Description, @Type, @Username, GETDATE()
SELECT
ItemId,
CustomerId,
@TopRelatedItemId,
Description,
Type,
Username,
TimeStamp
FROM
@TempItem
END
GO
So the question for you guys is is there a possibility to do something along the lines of:
DECLARE @TempCustomer TABLE
(
CustomerId uniqueidentifier,
FirstName nvarchar(100),
LastName nvarchar(100),
Email nvarchar(100)
);
SELECT
CustomerId,
FirstName,
LastName,
Email
INTO
@TempCustomer
FROM
Customer
WHERE
CustomerId = @CustomerId
So that I could reuse this data from memory in other following statements? SQL Server throws a fit with the above statement, however i don't want to have to create separate variables and initialize each one of them via a separate SELECT statement against the same table.... UGH!!!
Any suggestions on how to achieve something along the lines without multiple queries against the same table?

Sounds like you want temp tables. http://www.sqlteam.com/article/temporary-tables
Note that #TempTable is available throughout your SP.
Note the ##TempTable is available to all.
"SELECT *
INTO
@TempCustomer
FROM
Customer
WHERE
CustomerId = @CustomerId"
Which means creating a new @tempCustomer
tablevariable and inserting data FROM Customer. You had already declared it above so no need of again declaring. Better to go with
INSERT INTO @tempCustomer SELECT * FROM Customer
I found your question looking for a solution to the same problem; and what other answers fail to point is a way to use a variable to change the name of the table for every execution of your procedure in a permanent form, not temporary.
So far what I do is concatenate the entire SQL code with the variables to use. Like this:
declare @table_name as varchar(30)
select @table_name = CONVERT(varchar(30), getdate(), 112)
set @table_name = 'DAILY_SNAPSHOT_' + @table_name
EXEC('
SELECT var1, var2, var3
INTO '+@table_name+'
FROM my_view
WHERE string = ''Strings must use double apostrophe''
');
I hope it helps, but it could be cumbersome if the code is too large, so if you've found a better way, please share!
If you wanted to simply assign some variables for later use, you can do them in one shot with something along these lines:
declare @var1 int,@var2 int,@var3 int;
select
@var1 = field1,
@var2 = field2,
@var3 = field3
from
table
where
condition
If that's the type of thing you're after
It looks like your syntax is slightly out. This has some good examples
DECLARE @TempCustomer TABLE
(
CustomerId uniqueidentifier,
FirstName nvarchar(100),
LastName nvarchar(100),
Email nvarchar(100)
);
INSERT @TempCustomer
SELECT
CustomerId,
FirstName,
LastName,
Email
FROM
Customer
WHERE
CustomerId = @CustomerId
Then later
SELECT CustomerId FROM @TempCustomer
you can do this:
SELECT
CustomerId,
FirstName,
LastName,
Email
INTO #tempCustomer
FROM
Customer
WHERE
CustomerId = @CustomerId
then later
SELECT CustomerId FROM #tempCustomer
you doesn't need to declare the structure of #tempCustomer
