reporting services - Create Optional Parameter conditionally -

-

I have two criteria called "loans" and "tier" ??? Both are the only select drop down list and I am getting value from these SQL queries for these parameters. Tier parameter is dependent on loan.

There are SQL queries in order to bring the loan and tier:

Choose the loan from the loan

Choose from the loan from where credit = @ lotion

There are some loans for which there is no data in the TIER table, hence these are displayed for loans and for the empty price level drop down. Apart from this, those who have some tires, for loans, etc., are displayed for the tier drop down.

Now, when I select a loan (for which there is no level), select me clearly empty tier from the tier drop down, otherwise it gives me a pop up message saying That's "Enter the value for the tier".

In this scenario, I want the user to clearly select the blank value, the user should be able to see the report, if he does not select the value for the level (pop Up message can not be seen).

Secondly, if the user loan (for which some are available available), then the user must select the tier from the tier drop down. Otherwise, verification popup message (รข ???? Please enter the value for Tier) should be shown.

Actually, I want to conditionally make alternate parameters if the tier has some value (for the selected loan), then the tier parameter must be compulsorily, otherwise it should be optional.

We can not control the parameter workflow to our desired extent

I will add a separate section of the query to the tire parameter.

Then I will set the default value for the tier parameter to the empty value. It can be difficult - you may have to choose an alternative price, eg. Set the default value for ISNULL (TIER, 'unspecified') , then unspecified .

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
