Stored Procedure Using A Declared Variable In Insert Query (inline Or Using EXEC)

May 14, 2008

Hello,

I have a stored procedure where I run an insert statement. I want to knwo if it is possible to do it using a variable for the table name (either in-line or with an EXEC statement without building a string first and executing that string. See examples of what I am talking about in both cases below:

I want to be able to do this (with or without the EXEC) :
------------------------------------------------------------------------------------

DECLARE @NewTableNameOut as varchar(100)


Set @NewTableNameOut = 'TableToInsertInto'


EXEC(
Insert Into @NewTableNameOut
Select * From tableToSelectFrom
)

------------------------------------------------------------------------------------

I can not do the above because it says I need to declare/set the @NewTableNameOut variable (assuming it is only looking at this for the specific insert statement and not at the variable I set earlier in the stored procedure.


I can do it like this by creating a string with the variable built into the string and then executing the string but I want to know if I can do it like I have listed above.

------------------------------------------------------------------------------------

DECLARE @NewTableNameOut as varchar(100)


Set @NewTableNameOut = 'TableToInsertInto'


EXEC(
'Insert Into ' + @NewTableNameOut + ' ' +
'Select * From tableToSelectFrom'
)

------------------------------------------------------------------------------------



It is not an issue for my simple example above but I have some rather large queries that I am building and I want to run as described above without having to build it into a string.

Is this possible at all?

If you need more info please let me know.

Can't TABLE Variable Be Used In EXEC Statement In Stored Procedure

Feb 8, 2008

Hi

I've used a temporary table in the stored procedure

I've created it as DECLARE @Temp TABLE (id INT)

in select clause I've used this temp table through the joins..

But I've also used a varchar variable to store my criteria...

which I'm building in the stored procedure

so inorder to use it in the where clause I used

EXEC ('SELECT ....................


FROM @Temp T

LEFT OUTER JOIN ...
LEFT OUTER JOIN ...
WHERE ' + @Criteria )


Unfortunately this is not working.
Giving the errror


Must declare the variable '@TempT'.

I had to use Temporary table using #, which I feel is really waste of memory...

Is there a way by which I can use my Table variable in the EXEC statement.

Thanks In advance

Integration Services :: Converting Stored Procedure To Inline Query

May 30, 2015

I have a stored proc that is being executed from an OLE DB Source component in my Data Flow. Takes one input parm, has several variables declared within, a derived table which is used in a join and all within a try catch block with transaction handling. No updates, just returning data, works great, except now I have been asked to replace these stored procs with inline queries.

ALTER PROCEDURE [dbo].[usp_Get_Test]
(
@numberOfMonthsint
)
AS
BEGIN
SET NOCOUNT ON
set transaction isolation level read uncommitted

[Code] ....

The problems I have run into so far are...

SQL command text in OLE DB Source Editor does not like:
- TRY/CATCH block
- Will not let me use my input parm (@numberOfMonths int)
- When I hard code in my input parm (select   @BeginDate = dateadd(MONTH, -1, GETDATE())) I can parse query and run the step but no results are returned. So I am let to assume that it does not like the @TESTY derived table.

The query here as a sample has had pivots removed as well, but research suggests this should be an issue in the SQL command text.

Also, I know not even to try the Build Query... cause it will complain about any variable declarations (i.e., declare @BeginDate datetime).

For instance, can I pull this off with an Execute SQL Task? The problem is I don't see this available in the toolbox for the Data Flow. 

Also, would my error handling be done in the Event Handlers tab now and if so, is there a good example of this?

Passing A SSIS Global Variable To A Declared Variable In A Query In SQL Task

Mar 6, 2008

I have a SQL Task that updates running totals on a record inserted using a Data Flow Task. The package runs without error, but the actual row does not calculate the running totals. I suspect that the inserted record is not committed until the package completes and the SQL Task is seeing the previous record as the current. Here is the code in the SQL Task:

DECLARE @DV INT;
SET @DV = (SELECT MAX(DateValue) FROM tblTG);
DECLARE @PV INT;
SET @PV = @DV - 1;

I've not been successful in passing a SSIS global variable to a declared parameter, but is it possible to do this:

DECLARE @DV INT;
SET @DV = ?;
DECLARE @PV INT;
SET @PV = @DV - 1;


I have almost 50 references to these parameters in the query so a substitution would be helpful.

Using Declared Variable As Passphrase Slows Query

Mar 13, 2008



I have two tables - gift_cards and history - each related by a field called "card_number". This field is encrypted in the history table but not in the gift_cards table. Let's say the passphrase is 'mypassphrase'. The following query takes about 1 second to execute with a fairly large amount of data in both tables:


SELECT max([history].[date_of_wash]) AS LastUse

FROM gift_cards AS gc LEFT JOIN history

ON gc.card_number=CAST(DecryptByPassPhrase('mypassphrase', HISTORY.CARD_NUMBER) AS VARCHAR(50))

GROUP BY gc.card_number


When I use a declared variable to contain the passphrase, the same query takes over 40 seconds. For example,


declare @vchPassphrase as nvarchar(20)

select @vchPassphrase = 'mypassphrase'

SELECT max([history].[date_of_wash]) AS LastUse

FROM gift_cards AS gc LEFT JOIN history

ON gc.card_number=CAST(DecryptByPassPhrase(@vchPassphrase, HISTORY.CARD_NUMBER) AS VARCHAR(50))

GROUP BY gc.card_number


This query is part of a stored procedure and, for security reasons, I can't embed the passphrase in it. Can anyone explain the discrepancy between execution times and suggest a way to make the second query execute faster?

Thanks,
SJonesy

I need to write a stored procedure using T-SQL to declare a cursor for containing id(staff_no), names and specialism of all doctors that have specialism, The contents of the cursor then are to be displayed using a loop and print statement to give a formatted display of the output of each record within the cursor.

The doctors table has the following columns with specialism allowing NULL values

doctor
(
staff_no CHAR(3),
doctor_name CHAR(12),
position CHAR(15),
specialism CHAR(15),
PRIMARY KEY(staff_no)

How To Create A Stored Procedure Of This Code (inline Sql In Aspx) ?

Jun 2, 2006

I have some SQL code as inline SQL (bad habit, I know). Now I want to convert this to an sproc, but I'm pretty much out of ideas here. The code looks like this:
string SQL = "SELECT * FROM MyDBTable WHERE 1=1";
if (txtMyField1.Text != "")
{
SQL = SQL + " AND MyField1 = @MyField";
}
if (txtMyField2.Text != "")
{
SQL = SQL + " AND MyField2 LIKE '%'+ @MyField2 + '%'";
}
if (txtMyField3.Text != "")
{
SQL = SQL + " AND MyField3 LIKE '%' + @MyField3 + '%'";
}
I have an search page built on ASP.NET 2.0. Based on what the user has entered to the form fields, the SQL in constructed on the fly. Since this is now inside codebehind file (aspx.cs), I want to get rid of it and move it to an sproc. But the question is how ? Some simple SQL clauses are easy to convert to an sproc but this is causing me lots of issues.

Variable Declaration In A Stored Procedure Query

Feb 15, 2002

I have the following lines embedded in a stored procedure

---
----
----
select @querystr = "select @lkinpos = pos_lkin_pos from "+@database+" where pos_clnt_id = "+str(@clntid)+" and pos_isin ="+"'"+ @isinno+"'"

print @querystr
exec(@querystr)
---
---
---

When i execute the above stored procedure, it returns an error as follows:

Server: Msg 137, Level 15, State 1, Line 1
Must declare the variable '@lkinpos'.

When i see the print @querystr statement, it returns the query str as follows:

select @lkinpos = pos_lkin_pos from nsdldpm..pos_mstr where pos_clnt_id = 10000045 and pos_isin ='ine227a01011'

This when executed independently, gives me the required output.

Can anybody solve this for me?
Thanks in advance

STORED PROCEDURE INSERT QUERY ADVICE

Jun 22, 2006

I have 3 tables:

1) users: users information
2) products: products available
3) purchases: has relationships to both the users and products tables.

How can I write a stored procedure that inserts to the Purchases table and
populates to the other two tables. I was thinking that the records have to be
populated first on the "users" and "products" table then
when my INSERT is done on the "purchases" table it will refer to the
other two tables. I tried query builder but it wouldn’t allow me to insert from
one single INSERT statement to one table. Any advice that on how to approach
this? Thanks you!

Exec Stored Procedure

Jan 10, 2006

Hi,

Hope someone can help me out here - I'm trying to design a data flow in SSIS which relies in part on a stored procedure as a data source - I'm running it through OLE DB.

Sure Exec MystoredProc works fine on preview and on parsing, but it refuses to acknowledge any of the columns, when I go to Edit-->Columns everything is blank.

Just out of interest - the reason I am using a stored procedure is because I dump the data into a temp table and then amend a couple of the columns to make it the same as my other database (for example where len(field) = 6 then field = '0000' + field).

Possibly I'm better off taking the raw data through the OLE connection and then transforming it through SSIS, but my gut feeling is I should minimise what I'm dumping into SSIS and offload the processing onto the local DB. Any thoughts?

Thanks

Rich

Exec Stored Procedure

Aug 20, 2007

Hi,



I'm new to SSIS and SQL Server 2005 and this is now driving me very mad!!



I have an OLE DB Command in my data flow task that I want to update a table with. I have looked round this forum and on Google and just can not find a solution or what I am doing wrong. So any help would be great!



The ole db command calls a stored procedure with two input variables:

exec stp_updedgrsholds status, temp_cr_num



from debugging the ssis it says it has updated 4 rows and also from doing a data view, the data it is updating seems all correct.

but nothing gets updated in the database.



If I call the stored procedure the following way

exec stp_updedgrsholds 'C', 87



It updates fine! I have tried a number of different way with @ symbols and assignment p_status = @status

but nothing seems to work.



Any ideas are much appreciated.

Set Value For Variable In A Declared Cursor

Feb 16, 2004

Hi,

I have a problem on setting the value for the variable in a declared cursor. Below is my example, I have declared the cursor c1 once at the top in a stored procedure and open it many times in a loop by setting the variable @str_var to different values. It seems the variable cannot be set after the cursor declared. Please advise how can I solve this issue.

------------------------------------------------------------------------
DECLARE @str_var VARCHAR(10)
DECLARE @field_val VARCHAR(10)

DECLARE c1 CURSOR LOCAL FOR
SELECT field1 FROM tableA WHERE field1 = @str_var


WHILE (Sometime TRUE)
BEGIN

....

SET @str_var = 'set to some values, eg. ABC123, XYZ123'

OPEN c1

FETCH c1 INTO @field_val

WHILE (@@fetch_status != -1)
BEGIN

PRINT @field_val
...

FETCH c1 INTO @field_val
END

CLOSE c1

END

DEALLOCATE c1

Thanks a lots,

Exec Twp Stored Procedure In A Main Stored Procedure

Apr 29, 2004

Hi there

i have a stored procedure like this:

CREATE PROCEDURE SP_Main

AS
SET NOCOUNT ON

BEGIN TRANSACTION

exec SP_Sub_One output

exec SP_Sub_Two output


IF @@ERROR = 0
BEGIN
-- Success. Commit the transaction.
Commit Tran
END
ELSE
Rollback Tran

return
GO


now the problem is, when i execute the stored procedure's inside the main stored procedure, and these sub sp's has an error on it, the main stored procedure doesnt rollback the transation.

now i can put the "begin transation" in the two sub stored procedure's. The problem is

what if the first "SP_Sub_One" executed successfully, and there was error in "SP_Sub_Two"

now the "SP_Sub_One" has been executed and i cant rollback it... the error occured in the
"SP_Sub_Two" stored procedure ... so it wont run ... so there will be error in the data

how can i make a mian "BEGIN TRANSACTION" , that even it include the execution of stored procedure in it.

Thanks in advance

open testCursor

Inline Variable Assignment

Jan 22, 2004

I have to write a query for printing multiple barcodes, depending on the quantity of items that came in the store, based on the order number.



DECLARE @num INT
SELECT BarCodes.BarCode, BarCodes.ArticleID, ArticlesTrafic.DocumentID, ArticlesTrafic.TrafficQuantity
FROM BarCodes INNER JOIN
Articles ON BarCodes.ArticleID = Articles.ArticleID INNER JOIN
getAutoNumberTable(@num) ON @num=ArticlesTrafic.TrafficQuantity
WHERE (ArticlesTrafic.DocumentID = @Param2)



The thing i would like to do, is somehow assign a value to @num and pass it to the getAutoNumberTable stored procedure, which generates a table of consequtive numbers, so that each record is displayed multiple times. Is it even possible to do it without using temp tables and loops?

Morning All,Can I have some help with this one please, I am having to make a fixed length text file based on information from the DBDeclare @EDIString varchar(MAX)Declare @RecordType varchar(2)Declare @RegistrationMark varchar(7)Declare @Model_Chassis varchar(11)Declare @LocationCode Varchar(4)Declare @MovementDate varchar(8)Declare @IMSAccountCode varchar(5)Declare @MovementType varchar(8)Declare @NotUsed1 Varchar(28)Declare @NotUsed2 varchar(7)Select @RecordType = RecordType, @RegistrationMark = RegistrationMark, @Model_Chassis = Model_And_Chassis, @LocationCode = LocationCode, @MovementDate = MovementDate, @IMSAccountCode = IMSAccountCode, @Movementtype = MovementTypeCode from Fiat_OutBoundOnce I have selected the information from the DB I need to ensure that each field is the correct length.  I therefore want to pass the variable and the length of the variable into a function to return the correct length.So if location Code = 'AB'  this needs to be four characters long so want to pass it into a function and return 'AB  'As I need to do this for 70+ variables is there an easy way to obtain the length of the collation for the variable?regardsTom

Select Declared Variable With Case Statements

Apr 19, 2008

I am trying to gather counts for table imports made for files from friday - sunday and create a variable that will be the body of an email.
I'd like to use either a case statement or a while statement since the query is the same but the values must be collected for each day (friday, saturday and sunday) and will all be included in the same email.

I have declared all variables appropriately but I will leave that section of the code out.


Select @ifiledate = iFileDate from tblTelemark where
iFileDate = CASE
WHEN iFileDate = REPLACE(CONVERT(VARCHAR(10), GETDATE()-3, 101), '/','') THEN

Select @countfri1 = Count(*) from tbl1
Select @countfri2 = Count(*) from tbl2
Select @countfri3 = Count(*) from tbl3
Select @countfri4 = Count(*) from tbl4


WHEN iFileDate = REPLACE(CONVERT(VARCHAR(10), GETDATE()-2, 101), '/','') THEN
Select @countsat1 = Count(*) from tbl1
Select @countsat2 = Count(*) from tbl2
Select @countsat3 = Count(*) from tbl3
Select @countsat4 = Count(*) from tbl4

WHEN iFileDate = REPLACE(CONVERT(VARCHAR(10), GETDATE()-1, 101), '/','') THEN
Select @countsun1 = Count(*) from tbl1
Select @countsun2 = Count(*) from tbl2
Select @countsun3 = Count(*) from tbl3
Select @countsun4 = Count(*) from tbl4


END

Is there a way to do what this that works???
