OPEN C_TABLE
FETCH NEXT FROM C_TABLE INTO @TABLE_NAME

WHILE @@FETCH_STATUS = 0
BEGIN
FETCH NEXT FROM C_TABLE INTO @TABLE_NAME
PRINT @TABLE_NAME

How to remove the prompt name and border from Value prompt

Value prompt has the prompt name and the border(------------) in the list. You can remove these from the list with Java script.

• Set ID on the property of the dropdown list
• Add two 'HTML Item'd after the dropdown list
• Edit first HTML Item as follows

<script type="text/javascript">
function go(){
  var combo1 = document.getElementsByName("_oLstChoicesC0")[0];
  var combo1List = combo1.getElementsByTagName("OPTION");

  combo1.removeChild( combo1List.item(1) );
  combo1.removeChild( combo1List.item(0) );

}
</script>

_oLstChoices means a dropdown list. C0 is ID which is set in the property.

• Edit second HTML Item as follows

This is to execute Java script on that report.

How to run DTS from Stored Procedure

You can run DTS package from the client PC by these ways.

• Run DTSRUN.exe (It is provided as DTS utility.)
• Call the method in DTS object
• Call stored procedure (Stored procedure is necessary to be prepared in server side.)

The first 2 ways are necessary to install component in client. So I'll introduce the last way this time. There are two ways to run DTS from stored procedure.

Run DTS by xp_CmdShell

1. Create the command file (.bat or .vbs and so on) to execute DTSRUN
2. Create the stored procedure to call xp_CmdShell to execute the command file which is created in step1
3. Call the stored procedure

Run DTS by SQLServer Agent

1. Create SQLServer Agent job to run DTSRUN
2. Create the stored procedure to call sp_start_job
3. Call the stored procedure

CREATE PROCEDURE [ExecuteDTS_TestPackage] AS
EXECUTE msdb..sp_start_job @job_name = 'TestPackage'

GO

  sysobjects 
WHERE 
      OBJECTPROPERTY(id, N'IsUserTable') = 1 
  AND status >= 0 
ORDER BY 
  name

OPEN C_TABLE
FETCH NEXT FROM C_TABLE INTO @TABLE_NAME

WHILE @@FETCH_STATUS = 0
BEGIN
  FETCH NEXT FROM C_TABLE INTO @TABLE_NAME
  PRINT @TABLE_NAME
  SET @SQL = 
      '
        INSERT INTO TEST
        SELECT ''' +
          @TABLE_NAME + ''' AS TableName
          ,COUNT(*) AS NrOfRecords

Import stored procedure as a Metadata on Framework Manager

Edit definition of stored procedure

If ths stored procedure has a parameter, you have to set the value in this form.

Click Test before setting the value and Set 1 in value on Prompt Values form

Select the parameter and click Edit

Set the value on Edit Value form

?PROMPT_NAME?
You can use user prompt here with this expression. When user runs a report which uses this data source, this prompt is shown. The stored procedure is imported as a data source. Then it is be able to used in Report Studio/Query Studio.

ReportNet : Prompt Customize - Default Value

You can use default value in a dropdown list with Java script. It is also possible to change first word in that.

• Set ID on the property of the dropdown list
• Add two 'HTML Item'd after the dropdown list
• Edit first HTML Item as follows

<script type="text/javascript">
function go(){
 var combo1 = document.getElementsByName("_oLstChoicesC0")[0];
 combo1(0).text="All Customer";
 combo1(1).text="------------------------------";
 combo1.selectedIndex="0";
}
</script>

_oLstChoices means a dropdown list. C0 is ID which is set in the property. Change the number combo1.selectedIndex="0" to the default index. You can change the first word if you change the strings in combo1(0).text.
