    <p>I need to return 2 values from stored procedure in my application. Below is the code snippet in my application. I need to get the values of SureveyID &amp; InputID below after the respective insert statements. </p> <pre><code> int surveyId = 0; int inputId = 0; SqlDataManager manager = new SqlDataManager(); manager.AddParameter("@Name", surveyInstance.SurveyName); manager.AddParameter("@Type", surveyInstance.SurveyType); manager.AddParameter("@UserId", surveyInstance.UserId); manager.AddParameter("@InputType", surveyInstance.InputType); manager.AddParameter("@DisplayName", surveyInstance.DisplayName); manager.AddOutputParameter("@SurveyID",System.Data.DbType.Int32,surveyId); manager.AddOutputParameter("@InputID", System.Data.DbType.Int32,inputId); manager.ExecuteNonQuery("pr_CreateSurvey"); </code></pre> <p>AddParameter &amp; AddOutputParameter is custom method as below</p> <pre><code> public void AddParameter(string parameterName, DbType parameterType, object parameterValue) { SqlParameter parameter = new SqlParameter(); parameter.ParameterName = parameterName; parameter.DbType = parameterType; parameter.Value = parameterValue; parameters.Add(parameter); } public void AddOutputParameter(string parameterName, DbType parameterType, object parameterValue) { SqlParameter parameter = new SqlParameter(); parameter.ParameterName = parameterName; parameter.DbType = parameterType; parameter.Value = parameterValue; parameter.Direction = ParameterDirection.Output; parameters.Add(parameter); } </code></pre> <p>Below is code snippet from stored procedure</p> <pre><code>ALTER PROCEDURE [dbo].[pr_CreateSurvey] -- Add the parameters for the stored procedure here @Name varchar(50),@Type varchar(50),@UserId varchar(50),@InputType varchar(50),@DisplayName varchar(50), @SurveyID int OUTPUT,@InputID int OUTPUT AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; -- Insert statements for procedure here Insert into surveys(name,user_id,display_name,type) values(@Name,@UserId,@DisplayName,@Type) SET @SurveyID = SCOPE_IDENTITY() Insert into input_types(name) values (@InputType) SET @InputID = SCOPE_IDENTITY() END </code></pre> <p>The insert statements are working fine but I am not getting back any value in my application. Its 0. I tried returning 1 value(SurveyID) by using below statement but still not getting correct value. Its returning -1 everytime.</p> <pre><code>surveyId = manager.ExecuteNonQuery("pr_CreateSurvey"); </code></pre> <p>I tried a lot but no luck. Please advise.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
