Query for parameter suggested values (global variable for entire project?)

We are trying to set global variables StartDate and EndDate that all queries can references as a filter.

 

I would like to set StartDate to this TSQL formula SELECT DATEADD(MONTH, -12, DATEADD(MONTH, DATEDIFF(MONTH, '19000101', GETDATE()) - 1, '19000101')) 

 

When I select Query (see screenshot below) from the Suggested Value box, it doesn't let me enter the formula into the Query box. 

 

If setting a single value in a parameter that all queries can reference is not an option, what are the other options?

 

Thanks in Advance

@jch Query dropdown doesn't let you write formulas there but only reference other queries. So in your model create another query that returns or contains value from your TSQL and then reference that query under Query section for Parameters.

I created a new datasource with the Global Date Parameters for reference. It still won't let me enter in anything at all in the Query dropdown box. Is there another step I need to follow?

 

Thanks in advance

Hi @jch,

You can perform the following steps to populate the parameter list based on a query.

1. Import a table from SQL Server by writing your T-SQL in SQL statement(optional) textbox as shown in the following screenshot.

2. Get a list from the date column in the imported table,  you would need to click on the column to select it and then right-click and select “Add as New Query”. Now you have a list named Query 3 whose values are derived from your T-SQL formula.

3.When you create new parameter, you will be able to choose Query 3 as follows.

Thank you for the feedback, still encountering problems. I followed instructions as noted in screenshot below and the Query dropdown box still won't accept values. Is there anything else I'm missing?

Hi @jch,

Based on your screenshot, you are missing the step that get a list from the date column in your table. As stated in the blog I have post, To get a list from a column in your table,  you need to click on the column to select it and then right-click and select either:

  • Drill Down
  • Add as New Query

After you successfully get a list, you can have a list mark which looks like as follows.
