Passing An Array And/or Variable Field Name To An SProc
Jul 20, 2005
I have 2 questions.
I am trying to write a stored procedure to update a table. I am trying
to pass a variable that represents the name of the column/field and
another for the value that I am changing.
For example:
@FieldName VARCHAR(100)
@FieldValue VARCHAR(100)
AS
UPDATE tblTHETABLE
SET @FieldName = @FieldValue
First is it possible to use a variable as the column/field name? If
so, how do I go about it?
Also, it would be nice if I could have the @FieldName and @FieldValue
variables as arrays. Is that possible?
Thank-you for any assistance

Is it possible to use a table's fieldname as an SQL variable?
i.e. can the below be made to somehow work:
Code:
SELECT Firstname, Surname, myVariable
FROM ContactDetails
WHERE myVariable = [user input];
- or simply -
Code:
SELECT Firstname, Surname, [user input]
FROM ContactDetails;
---
The "user input" being any other chosen column/fieldname from the ContactDetails table (e.g. Street, City, Postcode, etc.).
i'm using Access and ASP - in case that makes a difference.
any help would be greatly appreciated.

Dear all,
I need to pass an Array of string from .NET in C# to a store procedure. I do not know in advance the size of the array.
When this array is pass to my store procedure, I need to copy the all content of the array into an SQL table.
Based on that I have different question :
1 - is it possible to pass an Array[] as a strore procedure parameter ?
2- If yes what is the syntax to declare an input parameter as an array ?
3- Does the array as parameter is the proper way to pass unknown amount of parameters ?
4 - If not what are the other solution ? I read some stuff on XML document but did not find any real example which explain clearly how it should be done
Thnaks for your help
regards
Serge

Hi,
I am trying to get the selected options from a listbox and either pass a SqlDataSource object the array or loop through it and pass each element of the array. I then need to modify the returned databtable to graphing function, but first drop the last column. I was wondering if anyone can help me with the following:
1. Pass an array into SqlDataSource Select OR 2. Pass a single argument into the Select statement and populate a datatable without it writing over the current row each time it iterates through the foreach statement. I am looking for the dataview to append to dt each time it loops. Is there a property for dataview that behaves like the "ClearBeforeFill" for table adapters?3. Update a parameter programmatically
Below code works, but I think it can be more efficient. Any suggestions would be greatly appreciated.
Thanks in advance!!
DataTable dt = new DataTable(); DataTable dt2 = new DataTable(); DataView dv = new DataView();
foreach(ListItem liOptions in ListBox1.Items) { if(liOptions.Selected) { SqlDataSource1.SelectParameters.Add("Parameter1", liOptions); dv = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty); dt2 = dv.Table; dt.Merge(dt2); dt2.Dispose(); SqlDataSource1.SelectParameters.Clear(); } }
if (dt.Rows.Count > 0) { Graph(dt); //Pass original datatable (dt) to Graph(); dt.Columns.RemoveAt(2); //Reformat datatable (dt) and remove last column before binding to Gridview1
GridView1.DataSource = dt; GridView1.DataBind(); } else {
errorMessage.Text = "No data was returned!"; }

I'm looking for a way to pass an array of values as a parameter to a query in a table adapter. For example I want to run a query something like:SELECT * FROM menu WHERE menu_role IN (@roles)And I could pass something like 'RegisteredUser, SuperUser, OtherUser' to the @roles parameter.For some reason I can't figure out a way to do this. Any help would be greatly appericated.Thanks,Ryan.

Well, I managed to write a Stored procedure that updates some records in the Northwind Database based on the ProductIDs passed to the SP as a list of strings. This is the Alter version of the SP:USE [Northwind]
GO
/****** Object: StoredProcedure [dbo].[gv_sp_UpdatePOs] Script Date: 06/10/2007 12:07:54 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROC [dbo].[gv_sp_UpdatePOs]
(
@IDList varchar(500),
@ReorderLevel int,
@ProductName nvarchar(30)
)
AS
BEGIN
SET NOCOUNT ON
EXEC('Update dbo.Products
SET ReorderLevel = (' + @ReorderLevel + ') ,ProductName = (''' + @ProductName + ''')
WHERE ProductID IN (' + @IDList + ')')
END
----------------------
THis works fine inside Sql Server 2005 Query analyser.
But when I setup an aspx page with an objectDataSource inside the page attached to an xsd file where the Products table is located. When I try to add new query to the tableadapter inside the Products table and point to the stored procedure in the wizard I get this error: " the wizard detected the following problems when configuring TableAdapter query "Products" Details: Generated SELECT statement. Incorrect suntax near ')'.
Any help would be appreciated
And can someone convert it to support XML instead of list of strings. thanks.

I have to send an array, which are generated in C++ (or C#) to an SQL-INSERT. Something like this:
INSERT INTO Table1
(Col1,Col2)
VALUES(:a,:b)
// a and b are my arrays//:a=A,B,C,D.....//:b=1,2,3,...
Is there any way to do something like my prototype in MS SQL Server? If yes how should be my INSERT?

I want to do something like this in a stored proc:------Create Procedure dbo.GetPatients@PatientIdList varchar(200) -- comma separated list of PatientIDsAsSelect *From PatientsWhere PatientId In (@PatientIdList)------I know the above won't work, but of course what I want is if@PatientIdList = '1,2,3' then I want Patient records with PatientIds1, 2, and 3 returned.It looks like the only way to do this is to build the SQL statement asa string within the stored procedure ... which pretty much defeats theusefulness of using precompiled sprocs as I understand it (better offbuilding a dynamic query against a View in that case).Thoughts?Joel Thornton ~ <groups@joelpt.eml.cc>

I have a table that looks like this:
RecordId
PictureId
KeywordId
111
212
313
421
522
623
725
817
932
1044
I need to run a query where I pass in an unknown number of KeywordIds that returns the PictureId. The 'IN' clause will not work because if a KeyWordId gets passed into the Stored Procudure the PictureId must have a record with each KeyWordId being passed in. For example, lets say you need to see the result of all PictureIds that have both 1 and 2, the correct result set should only be PictureId 1 and PictureId 2.
Im going crazy trying to find a simple solution for this. Please advise.

Is there any way to use a 2 dimensional array of strings as the Variable Enumerator for the "Foreach From Variable Enumerator". I am trying to copy a collection of files from folder A to folder B. In a script, I would populate, let us say, an array of (2,10), for 10 files, with one column representing the source file and other column representing the target column task. Then I would like to set this string array variable as the "Variable Enumerator" for the "Foreach From Variable Enumerator" and use file system tasks in the foreach loop to perform the tasks. The problem is that the "Foreach From Variable Enumerator" does not let me choose an index, but passes only one index 0, so, I will only be able to pass just one column. How do I let the foreach enumerator let me choose an index. The other foreach enumerators, foreach item and ADO give me the option to select index. I would like the same functionality in the foreach variable.
Note: I cannot use the "For Each File" enumerator, since the files are to be selected by a script only.
Thanks for the help.

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.

Hi,
I want to perform Oracle's VARRAY like implementation in SQL SERVER. How should I go about it?
I've done an implementation in Oracle where I have a VARRAY variable which stores a number of insert statements where each INSERT statement is a single array element. I then traverse through the VARRAY and executed each INSERT statements inside a loop.

Dear all,
I have a problem using SSIS since I was a beginner, the problem is I have to do some data transform from flat files into database. These flat files come from many branches of my office with the file structure like this D:SSISranch_nmfile_nm.txt, in folder SSIS there are many branch_nm folder and each branch_nm folder contains many flat files.
My idea was grab the branch_nm folder into array variable using Script Task and then loop this array variable using ForEach Loop Container to get the file and using it for Flat File connection, but I don't know the way to do it.
May this idea work out for sure ?? How to use array variable, that we previously defined inside Script Task, in ForEach Loop Container ?
Thanks in advance

So I have a Web Service that works just fine when I enter the parameter values myself. I get results and can parse it out, storing the results into a table. I even have it working in a "For Each Loop" for one of my variables. The issue I have is that the Web Service accepts 3 variables, the first being an Array. How can I populate the array variable for web service?

I am between the "newbie" and "intermediate" stages of writing SQL code and I am wondering if there is a way to capture multiple results into one field so I can basically create a "set" for a unique identifier. Here is few result samples I receive from this code I am using now.
ReqNo ProcID
7102005 1409
7102005 1796
7139003 1411
7139003 6097
7261030 1409
7261030 1796
7268303 3998
7268303 4000
I would like to create a single row for each "ReqNo" and have a field that will an array of the "ProcID" results I receive. In other words, for the first "ReqNo" 7102005, can I create a field that will combine the 1409, 1796 into one field? I am trying to capture an array of integers used for that "ReqNo" so I can use that as a unique identifier in a join for another table.
So, ideally my result would be:
ReqNo ProcSet
7102005 1409, 1796
7139003 1411, 6097
7261030 1409, 1796
7268303 3998, 4000
Is this possible?

Hi - I'm using Session variables to store information (sort of webshop).
The sessions are a mix of the usual straightforward strings, wich are no problem - but I also have a DataTable which I store in a session variable, and I also have an array, which I store in a session variable eg. session("day")(x) where x is the item in the array.
I want to give my users the ability to store the items they've selected in my database, but have no idea of what type of field I should use for the datatable and array session variable. Should I use a TEXT field, or is there another more appropriate one'?
I'm using SQL Server 2000.
Thanks for any help,

Hi All!
I have a parent package that contains two children... The second child depends on the succes of the first child.
THe first child generates a variable value and stores it in an Environment variable ( Visibility - All ) ...After the first succeeds, the second will start executing and will pick up the variable value from environment variable( through package configuration setting )...
Unfortunately, this doesn't work...As the second child picks the stale value of the environment variables...Essentially it assigns variable value not after the first child is finished, but right at the beginning of parent execution...
I tried to execute coth children as Out Of Proc as well as In Proc...The same
Would anybody have an idea how to resolve this problem?
Thanks in advance for any help!

Hi,
This is pretty simple but I am doing somethin really stupid somewhere, I am trying to pass a value to a variable declared in a package using some SQL code, I declared a variable "var1" and assigned the scope to the package , then I dropped a execute SQL task within the package and wrote a simple sql code that would get the maximum id from a table, "select max(id) from table" , now I want to assign the variable this max value.so in the parameter mapping tab I select the variable give it a parameter name of 0 and size of -1 along with direction of "output". everythin looks simple but when I try to use this variable value in my next execute sql task it behaves weirdly, I am trying to update anothet table using this variable value, so I add another task and put this code in there " update table2 set id = ? " , and on the parameter mapping tab I set the direction as input, however when I look at the column it updated th column with a weird number , xomethin like "230072408" which doesnt mean anything. I know that tha max value of ID is 10.
Please help.
Thanks

hi guys what is the syntax for using the passing variable part into the name of a table in a store procedure. in particular: (assume already declared the variable periodseq.
select *
into Temp_Usage_@periodseq
from Master_usage
where Master_usage.PERIODSEQ = @periodseq
in particular the Temp_Usage_@periodseq line of code, how do i "add" the periodseq (which is a number) to the end of the name of Temp_Usage, i.e: Temp_Usage_112
is the syntax an & like Temp_Usage_&@periodseq?
Cheers

I've been coding a few years and SSIS makes me feel more stupid than any program I've ever used.
I've read BOL and bought a book. Can't say either one has really helped.
I'm still a complete idiot after one week of working with it. I apologize for asking so many stupid questions.
What I'm trying to do now is parameterize a SQL statement.
I have a variable that's a string. I have a DataFlowComponent as a data source. I find references all over the Internet and this forum to something called an "ExecuteSQLTask" but I sure can't figure out what that is. In my toolbox I have data flow sources for DataReader, Excel, Flat Files, Old DB, Raw file, and XML but no Execute Sql Task.
Anyway SELECT * FROM TABLE WHERE COLUMN='Value' in the SQL Command property is simple enough. Now I want 'Value' to be a variable. You know, like in T/SQL DECLARE @Foo VarChar(25). Creating the variable is easy as pie.
I have found at least 10 different examples of specifying variables on the web, all of which claim to be SSIS examples, Is it User::Variable? @[User::Variable]? @Variable?
I want to read rows from a table, with a a variable value in the WHERE clause, and pass them to the fuzzy lookup task.
Is my approach fundamentally flawed in some way?
