To fix the above issue, we have two ways.

Add the client IP in Azure SQL Server firewall.

Follow the below steps to add the client ip.

This will be applicable when you have SQL Server (Logical server) in Azure.
Step 1: Go to the SQL Server in Azure Portal

Step 2: Choose “Firewall”

Step 3: Click + Add Client IP and Save

Name mismatch (DataSet1) in SQL Server Mobile Report Publisher

This post explains a very simple error message that we may face if any issue with a shared dataset.

For example, take a below scenario

You have a shared dataset deployed to the report manager portal. The name of the dataset is Sales and you need to build a mobile report using Sales shared dataset.

When you use the Sales Shared Dataset from mobile report publisher, you may get an error message if any issue with the query used in Shared dataset or data source issue. The error message usually will say DataSet1 even though we used the proper name for the shared dataset.

It is because the shared dataset by default considering the name ‘DataSet1’ when you create a dataset. It can be identified and modified if you open the dataset file in notepad.

Add Data to Mobile Report Publisher

Recently, I saw a question raised in MSDN forum.

The question was “How to add data into Mobile Report Publisher?”

The answer is very simple, Mobile Report Publisher will use dataset for data.

If there are no datasets deployed to report server then we can’t see anything when using mobile report publisher data tab.

Steps to create dataset and make available for Mobile Report Publisher.

Step 2: Deploy the shared dataset to report server

Step 3: Make sure the deployed shared dataset is deployed successfully and check it in report server as well.

Step 4:  Click the Add data in Mobile Report Publisher.

SSRS Error Message – Cannot compare data of types System.Decimal and System.Double

I got a below error message when I execute the report. The error message is very straight forward and it highlights the exact issue.

Basically, this error occurred due to different data types. There are many situations where we get this error so I thought to document this scenario.

Error Message,

An error occurred during local report processing.

An error has occurred during report processing.

The processing of FilterExpression for the dataset ‘Dataset1’ cannot be performed. Cannot compare data of types System.Decimal and System.Double. Please check the data type returned by the FilterExpression.

SSRS Error

Error Reason:

In Dataset1, I used a filter property and filtered “Unit Price” greater than 12. When I choose Unit Price column, it automatically picked the data type as float as it has values like xxx.xx in table.

SSRS

The Original data type of the Unit Price column in the database is different, it is money data type. There is a mismatch of the data type.

Solution:

There are two ways to handle this issue.

1.      We can filter the value (Unit Price > 12) in script level and directly pass the script in dataset Instead of using dataset filter properties. We also will get good performance. Check my post on …..

2.      If we want to use the dataset filter then we need to convert the unit price column into SSRS supported data types, in this case, float.

 convert(float,[UnitPrice]) as UnitPrice

 Available data types in dataset filter.

SSRS 2
