Removing SQL Parameters From Command Object After Use.
Sep 26, 2006
Hi all,
is it good practice to remove SQL Parameters from the Command Object's parameters collection after the CommandObject has executed its SQL containing the SQL Parameters?
The reason I ask is because I have encountered some issues (errors) stating that the SQL Parameter cant be used because it is still contained in another Parameter collection - ( I created the Parameters, and then use these same parameter (through looping) to execute new commands).
Thanks

Hi All,
i am using a OLE DB Source in my dataflow component and want to select rows from the source based on the Name I enter during execution time. I have created two variables,
enterName - String packageLevel (will store the name I enter)
myVar - String packageLevel. (to store the query)
I am assigning this query to the myVar variable, "Select * from db.Users where (UsrName = " + @[User::enterName] + " )"
Now in the OLE Db source, I have selected as Sql Command from Variable, and I am getting the variable, enterName,. I select that and when I click on OK am getting this error.
Error at Data Flow Task [OLE DB Source [1]]: An OLE DB error has occurred. Error code: 0x80040E0C.
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E0C Description: "Command text was not set for the command object.".
Can Someone guide me whr am going wrong?
myVar variable, i have set the ExecuteAsExpression Property to true too.
Please let me know where am going wrong?
Thanks in advance.

Hi. I am writing a program in C# to migrate data from a Foxpro database to an SQL Server 2005 Express database. The package is being created programmatically. I am creating a separate data flow for each Foxpro table. It seems to be doing it ok but I am getting the following error message at the package validation stage:

I currently have a connection class that handles all of my database connectivity. What I am trying to do is build a SqlParameterCollection object on one page, then pass that object to my connection class. Is it possible to do this? I am not getting any compilation errors, but I can not get the parameters to be recognized. Here is what I am trying to do:
Page 1:
string sql = null;
conn.strConn = connectionstring;
sql = "sqlstring";
SqlParameterCollection newcollect = null;
newcollect.Add("@Switch",1);
conn.OpenReader(sql, newcollect);
while (conn.DR.Read())
{
read data onto page here...
}
conn.CloseReader();
Page 2 (connection class) :
public void OpenReader(string sql, SqlParameterCollection collect)
{
Conn = new SqlConnection(strConn);
Conn.Open();
Command = new SqlCommand(sql,Conn);
Command.Parameters.Add(collect); <------This is the root of my question
Command.CommandTimeout = 300;
// executes sql and fills data reader with data
DR = Command.ExecuteReader();
}
Can you do this??? And if so, can anyone tell me why the statement will not return any data? The procedure works perfectly, and will work if I use the standard way of passing the parameters to the command statement.

Hi all, I'm having some trouble using the SQL IN command when using a parameter that contains the IN data.For example, without using parameters, I could do:select * from assetsmaster where extension in ('doc','vsd')But I would like to do it this way:select * from assetsmaster where extension in (@strFile)My stored procedure would look similar to this:GOCREATE PROC dbo.GetAssetList2( @xmlFileList varchar(1000), @strContainsClause varchar(1000), @strFileTypes varchar(1000))ASBEGIN SET NOCOUNT ON DECLARE @intDocHandle int EXEC sp_xml_preparedocument @intDocHandle OUTPUT, @xmlFileList SELECT DISTINCT AssetsMaster.AssetMasterUID, AssetsMaster.AssetFileName FROM AssetsMaster WHERE AssetsMaster.Extension IN (@strFileTypes)What format does the parameter need to be in? I can't execute the procedure like this, as it tries to parse the parameter before executing, I think:USE [GTGAssets]GODECLARE @return_value intEXEC @return_value = [dbo].[GetAssetList2] @xmlFileList = N'<NewDataSet...Table></NewDataSet>', @strContainsClause = N'soa', @strFileTypes = N'''DOC'',''VSD'',''BMP''' <<<Those are all single quotesSELECT 'Return Value' = @return_valueGOSo my problem is, how does the parameter get passed so I can test it?Thanks!James

Hello!
Is there a way to use an OLE DB Command transform to execute the following SQL query?
"Select sum(length(" + @[User::varDBName] + ":informix.cyh_t.u_obj)) from " + @[User::varDBName] + ":informix.cyh_t, " + @[User::varDBName] + ":informix.cch_t
where " +
@[User::varDBName] + ":informix.cch_t.d_obj = {D '" + @[User::strQueryDate] + "'} and " +
@[User::varDBName] + ":informix.cch_t.n_objid = " + @[User::varDBName] + ":informix.cyh_t.n_objid"
I get a DB number from an OLE DB Source, do a lookup to get the DB name and then I want to use the OLE DB command to get a result from the query but I can't seem to get this to work. Am I using the wrong transform?
Thanks.

Hi All,
I have an sql command which has subqueries in it. I need to pass in variables like startdate and enddate to the sub query query and then execute the query. What is the best way to do this?
I am trying to use ole db source but this has a limitation of not allowing parameters at the sub query level. What else can I use? I am working with sql server 2005.
Thanks a lot.

Hi all,
A quick newbie question...
I am trying to install SQL Server 2005 Standard and upgrade from Express edition. The Edition Change check tells me I must run the setup from the command prompt "and include the SKUUPGRADE=1 parameter", but I don't know how to enter this from the command line.
I've tried "D:setup SKUUPGRADE=1" and "D:setup -SKUUPGRADE=1", as well as "D:setup.exe /SKUUPGRADE=1" without success.
Can anyone give me a clue as to where I'm going wrong?
Thanks in advance.

I am trying to use the OLE DB Command component in a data flow. I setup the connection manager and then entered the following SQL command.
UPDATE FCustomer
SET FId = CASE
WHEN ISNULL(@p1, 'N') = 'Y' AND @p2 IS NULL THEN '2'
ELSE '3' END
WHERE Id = @p3
AND CustomerId = @p4
So after that I went to the parameter tab and tried to set the data types. I assigned the data types. Mapped the fields to the paramters and hit ok. Ran the package and failed with a cast/conversion issue. When i went back in the parameters are all set back to the Integer 8 data type. I change, go back in and reset again. The help file says I can change the parameter names and data types, which it allows me to do, but never saves the settings.
Am I doing something wrong? Is this not possible?
Thanks!

When I run the parse command in SSMS, it merely does a syntax check. When I run through the export data wizard by right clicking on a table, it allows a query as the data source. When I click on the parse button in the window that accepts that query, it resolves object names and notifies me of invalid ones. I'd really like the same thing to happen when I parse in SSMS...

SelectCommand="SELECT [id], [ref_id], [ref_name] FROM [ref] where [delete_flag] = 'N' AND [flag_transmit] = 'N' AND [ref_name] = @ref_name ">
<asp:ControlParameter Name="ref_name" ControlId="SrchRefName" PropertyName="Text" ConvertEmptyStringToNull="false"/>
The gridview of all the records is displayed on the page by default. There is a lookup of SSN and Name and putting values in those fields should filter the records and display only the row containing entered Name.I have trouble with the SelectCommand. No gridview is displayed with the above command even if value is entered in the Lookup textBox (SrchRefName).But when I change the selectcommand to- (using OR) SelectCommand="SELECT [id], [ref_id], [ref_name] FROM [ref] where [delete_flag] = 'N' AND [flag_transmit] = 'N' OR [ref_name] = @ref_name "> <asp:ControlParameter Name="ref_name" ControlId="SrchRefName" PropertyName="Text" ConvertEmptyStringToNull="false"/> the default gridview is displayed with all the records even though a value is entered in the lookup text box.

I have a package that let me to import data from a excel book to a Sql server data base. When I try to run this package like a step into a SQL server Job it show me the next error.
"The command line parameters are invalid. The step failed."
the "command line" looks like this
/FILE "C:ProjectPackage.dtsx" /CONNECTION ConexionExcel;"Provider=Microsoft.Jet.OLEDB.4.0;Da ta Source=;Extended Properties=""EXCEL 8.0;HDR=YES"";" /MAXCONCURRENT " -1 " /CHECKPOINTING OFF /REPORTING EWCDI
and in my excel conexion is:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=;Extended Properties="EXCEL 8.0;HDR=YES";
When i run the "Command Line" in the "Command window" the error is more expecific
"EXCEL 8.0;HDR=YES;" is not valid
So I chanded the "Command Line" in order to run it in de command window(look the double quote in the excel properties)
/FILE "C:ProjectPackage.dtsx" /CONNECTION ConexionExcel;"Provider=Microsoft.Jet.OLEDB.4.0;Da ta Source=;Extended Properties="EXCEL 8.0;HDR=YES";" /MAXCONCURRENT " -1 " /CHECKPOINTING OFF /REPORTING EWCDI
then the package RUN, but when i tried to do the same thing in the
sql wizzard, it just dont work and it lost the threat from de package and the errors says this time:
Couldn't find the package
Some one who knows the answer or has any idea to helpme please?

Hi there,
In order to prevent lookup errors in a lookup transformation, I've decided to go for an OleDb Command Transformation.
This transformation should check the lookup and, if it turns out to be null, ir returns a dummy value. Otherwise, it would return the lookup value.
This should be done by doing something like this:
select coalesce( (select ID_Table2 from ID_Table2 where FK_Table1 = ?), 0)
suposing Table2 has an atribute called "FK_Table1" that should match a column in the data flow.
Now, such command result in this message:
"An OLE DB record is available. Source "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Syntax eror, permission violation, or other nonspecific error".
But, it I remove the coalesce and type the following command:
select ID_Table2 from ID_Table2 where FK_Table1 = ?
It presents me no errors and allows me to continue.
Did i did anything wrong or is this something that is not possible to be done?
I know i have the option to use a script task to do this operation, but that would turn the maintenance process a little more difficult.
Otherwise, i know i could also re-direct the error from the lookup transformation and handle it. Though, my package has about 10 lookups and that would turn my package a lot more complex than
Thanks in advance
Best Regards

I have an update command with 7 parameters, but at run time the order to the parameters gets mixed up.
I'm using a stored procedure. At first I have the command type set to text, and was calling it using EXEC spName ?,?,?,?,?,?,?
I then named each of the parameters and set their sources. The parameters are like this (samepl name, then source, then type):
A : QueryString - intB: Control - intC: Control - intD: None - intE: None - decimalF: Control - datetimeG: Control - datetime
At run time I was getting an error that an integer couldn't be converted to date time. So I put a breakpoint in the Updating event and then looked at the parameters prior to update.
This is how they looked (Parameter index, paramter name):
[0] A[1] B[2] D[3] E[4] F[5] G[6] C
It didn't maek any sense. Do, I deleted all of the paramters and readded them. That didnt' work. Then I changed the command to StoredProcedure and refreshed the parameters from the stored proc and it brought them in the right order, but the problem remains the same.
I looked at the page source, and there are no indexes in the page source, but the parameters are listed in the proper creation order, as follows:<UpdateParameters><asp:QueryStringParameter Type="Int32" Name="PROJ_ID" QueryStringField="pid"></asp:QueryStringParameter><asp:ControlParameter PropertyName="SelectedValue" Type="Int32" Name="TASK_UID" ControlID="fvTask"></asp:ControlParameter><asp:ControlParameter PropertyName="SelectedValue" Type="Int32" Name="ASSN_UID" ControlID="gvResources"></asp:ControlParameter><asp:Parameter Type="Int32" Name="RES_UID"></asp:Parameter><asp:Parameter Type="Double" Name="Work"></asp:Parameter><asp:ControlParameter PropertyName="Text" Type="DateTime" Name="Start" ControlID="TASK_START_DATETextBox"></asp:ControlParameter><asp:ControlParameter PropertyName="Text" Type="DateTime" Name="Finish" ControlID="TASK_FINISH_DATETextBox"></asp:ControlParameter></UpdateParameters>
No mater what I do, at run time ASSN_UID is always the last parameter. I've also run a SQL trace to see how it is actually being executed, and sure enough, its passing the value for ASSN_UID as the last parameter, which obviously doesn't work.
Any ideas as to why this would happen or how to fix it?
(I guess I can reorder the patameters in the stored proc to match how they are being passed, but still, that wouldn't be a very comfortable solution, since it could perhaps revert at some point or something)

Hello all,I'm writing a site with one page that uses the session variable (User ID) to pick one user ID out of a comma separated list in the field Faculty. The default parameterized query designed in the SqlDataSource wizard only returns lines that contain an exact match:SELECT * FROM tStudents WHERE ([faculty] = @faculty) The query: SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') works as I need when I hard code the query with a specific user ID into the SqlDataSource in the aspx page. It will not work if I leave the @faculty parameter in it:SELECT * FROM tStudents WHERE ([faculty] LIKE '%@faculty%') e.Command.Parameters works to replace the @Faculty with a user ID, but again, adding the single quote and percentage sign either causes errors or returns no results. I've tried several variations of: string strEraiderID = "'%" + Session["eRaiderID"].ToString() + "%'"; e.Command.Parameters["@faculty"].Value = strEraiderID;no results are returned, not even the lines returned with the default select query.How do generate the equivalent of SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') into the SqlDataSource? Thanks much!

Hi,
When I execute a stored procedure from an OLE DB Command transformation, where the sp takes a parameter and RetainSameConnection=TRUE and DelayValidation=TRUE are set, I get the error
"Syntax error, permission violation, or other nonspecific error"
If I take out the param or set RetainSameConnection=FALSE on the connection, all is fine again?
Has anyone has come across this?

Hi,
We have a lot of VB6 code that uses ADO 2.7 and stored procs wih Sql 2005. I have noticed recently that if I use the follow code:
Dim con As New ADODB.Connection
con.ConnectionString = "driver={SQL Server};server=(local);database=test;uid=sa;pwd="
con.Open
Dim com As New ADODB.Command
com.ActiveConnection = con
com.CommandText = "usp_GetSetting"
com.CommandType = adCmdStoredProc
com.Parameters.Append com.CreateParameter(...)
It will fail. the reason being the after setting the CommantText and Type ADO then seems to automatically go away and populate the Parameters collection from the databases metadata according to the SP we are calling.
I have never seen this before, I thought the Refresh method had to be called before the parameters collection get populated.
Can anyone help me please?

I have a stored proc with 28 commmands but only 24 are loaded. If I move the parameters around the ones that didn't show are visible and the ones after the 24th parameter don't show up. Is there some sort of limit on parameters for OLEDB commands that execute stored procs in the exec procname @p = ? construct?

Hello all,
Ok, I finally got my SqlDataSource working with Oracle once I found out what Oracle was looking for. My next hurdle is to try and set the Update Command and Parameters dynamically from a variable or radiobutton list. What I'm trying to accomplish is creating a hardware database for our computers by querying WMI and sending the info to textboxes for insertion and updating. I got that part all working nicely. Now I want to send the Computer name info to a different table column depending on if it is a laptop or desktop. I have been tossing around 2 ideas. A radiobutton list to select what it is and change the SQL parameters or do it by computer name since we have a unique identifier as the first letter ("W" for workstation, "L" for Laptop). I'm not sure what would be easiest but I'm still stuck on how this can be done. I posted this same question in here a few days ago, but I didn't have my SqlDataSources setup like I do now, I was using Dreamweaver 8, it is now ported to VS 2005. Below is my code, in bold is what I think needs to be changed dynamically, basically i need to change DESKTOP to LAPTOP...Thanks for all the help I've gotten from this forum already, I'm very new to ASP.NET and I couldn't do this without all the help. Thanks again!
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:CAT %>"ProviderName="<%$ ConnectionStrings:CAT.ProviderName %>" SelectCommand='SELECT * FROM "COMPUTER"' UpdateCommand="UPDATE COMPUTER SET DESKTOP = :DESKTOP, TECH = :TECH, SERVICE_TAG = :SERVICE_TAG WHERE USERNAME=:USERNAME">

Hi everybody, I would like to know if it's possible to execute a stored procedure, passing it parameters, using not CommandType.StoredProcedure value of sqlcommand, but CommandType.Text.
I tried to use this:
sqlCmd.CommandType = CommandType.Text
sqlCmd.Parameters.Add(sqlPar)
sqlCmd.ExecuteNonQuery()
With this sql command:
"exec sp ..."
I wasn't able to make it to work, and I don't know if it's possible.
Another question:
if it's not possible, how can I pass a Null value to stored procedure?
This code:
sqlPar = new SqlParameter("@id", SqlDbType.Int)
sqlPar.Direction = ParameterDirection.Output
cmd.Parameters.Add(sqlPar)
sqlPar = new SqlParameter("@parent_id", DBNull)
cmd.Parameters.Add(sqlPar)
doesn't work, 'cause I get this error:
BC30684: 'DBNull' is a type and cannot be used as an expression.
How can I solve this?
Bye and thanks in advance.
P.S. I would prefer first method to call a stored procedure ('cause I could call it with 'exec sp null' sql command, solving the other problem), but obviusly if it's possible...=)
Sorry for grammatical mistakes.

What is the correct command line parameters to SQLEXPR32.exe that will default the Log On As: properties for the instance to use the Built-in account of Local System & Local Service?
I need it to be set to Local System immediately on install without having to go into the configuration manager. When I run the SQLEXPR32.exe right now I get the Network Service defaulted.
Thanks for any help,
Greg

Hello
I want to use a for each loop container to go through all files listed in a particular folder.
Each of those file names must be passed as a parameter to the relog.exe command utility
example:
Folder C: emp
Files in C: emp: log1.csv, log2.blg, log3.txt
The following lines must be executed:
c:
elog.exe c: emplog1.csv -f SQL -o "SQL:PerfCounters!PerfCounters"
c:
elog.exe c: emplog2.blg -f SQL -o "SQL:PerfCounters!PerfCounters"
c:
elog.exe c: emplog3.txt -f SQL -o "SQL:PerfCounters!PerfCounters"
The relog utility converts the performance counter logs to sql format and pumps it in the database (DSN:PerfCounters)
The idea is that someone drops multiple counter logs in c: emp and you start a SSIS package to pump the data from all the files in the database.
I'm not sure where to start. Do I have to put a Script task inside the For Each loop container en start scripting the commands in Visual Basic.Net or is there a more simpler way to achieve this in SSIS?
Many thanks!

Hi
Microsoft confirmed that the error message "The command line parameters are invalid" issue mentioned above is a bug and has been resolved in the next "drop" of SQL Server 2005.
has this error been fixed by microsoft. Cos i still get this error!!!!!!!!!
I am also trying to run the package from command line and when i click on execute the package it runs half way and hangs. What could be the problem????.
But when i run it from my Studio and stored package it works fine!!!
Thanks,
Jas

Hi,
I'm very new to SSIS and I€™m trying to do the following in a SQL task
RESTORE DATABASE @DatabaseName FROM DISK = @Backup WITH FILE = 1, MOVE @OldMDFName TO @NewMDFPath, MOVE @OldLDFName TO @NewLDFPath, NOUNLOAD, REPLACE, STATS = 10
I'm using an OLE DB connection and I have mapped user variables to the various parameter names. Unfortunately when i test the above command it fails on must declare the scalar variable "@DatabaseName". How can i get my values to be substituted into the command?
Many thanks
Martin

Hello,
I created a SSIS package that has a flat file manager whose connection string is a package variable, the reason is that there is a foreachfile container loop to loop thru CSV format files in a directory and load them to a sql table.
The package execution is working in the designer studio as well as in the management studio-- a copy was saved to a sql 2005 server where a sql job is deployed to run the package. However when I ran the job, it claims successful but doesn€™t do anything in reality. If I checked the box failing the package upon validation warming, the job will fail with the error: the command line parameters are invalid. The command line looks like below:
/SQL "Package" /SERVER FTLQSQL03 /WARNASERROR /MAXCONCURRENT " -1 " /CHECKPOINTING OFF
One thing that I think maybe wrong is on the data source tab of the job step GUI, the flat file manager€™s connection string is blank, compared to other connection managers having related values.
Does anyone know how to make the job working?
Thanks in advance
I
