Question

I need to call a stored procedure during my report to insert values into a table. These values are the result of fields from the dataset added. For example, I have a row of values, and the far right column is "ReportItems!TextBox1.Value + ReportItems!TextBox2.Value ..." This gives the correct total on the report. Now I need to call a procedure using this value as a parameter.

Using a stored procedure as a dataset, I am unable to reference the ReportItems! I am also unable to create additional report parameters (even internal or hidden) which could be a result of a dataset due to the reporting infrastructure we are using.

I know using custom report code, I can call a stored procedure and also reference the ReportItems, but I have been unable to find the correct syntax. I am not familiar with VB.net so please be specific. If i could get an example of how to call: Procedure TEST_INSERT(ReportItems!TextBox1.Value), I would be able to figure out how to implement it.

I am using an oracle backend as my data source.
Thanks

If I’ve understood you correctly, you want to do an database update using a value calculated with an expression in your report. My answer to this would be threefold.

First up: don’t do it!.

Second: seriously, don’t do it!! Reporting services is not meant or well suited for this kind of task, you most likely are looking at an XY-Problem.

Third, if you insist on doing it anyways, the easiest way I can think of to accomplish that is by using a seperate report to trigger the update, and pass the value you’re after into a parameter for that report. In the main report, you set a click action on the cell with the total that calls the report, with the same value into the parameter.

A similar setup which may work as well, is to create a parameter based on the first dataset with that same “sum” expression you mention, and pass that down to another dataset.

However: don’t do it! 😉
