SQL Server Drop Database User

This blog post explains the issue that we usually face while dropping the users from the database and how can we resolve the issue.

We can create a user for database easily by any of the following user types,

  1. SQL User with login
  2. SQL User without login
  3. User mapped to a certificate
  4. User mapped to a asymmetric key
  5. Windows User

If we want to drop the user then we can write drop statement but it will throw a below error in case the user owned any of the schemas.

Msg 15138, Level 16, State 1, Line 20

The database principal owns a schema in the database, and cannot be dropped.

To resolve the issue, Follow the below steps.

Step 1: Check the schema that owned by the user.


FROM sys.schemas s

WHERE s.principal_id = USER_ID(‘Username’)

Step 2: Change the schema back to dbo.


Step 3: Drop the user

DROP USER <username>

SSRS Shared Dataset with Parameter

As you know, a dataset is the direct input component for SQL Server Reporting Services. These datasets are part of rdl files. Reports can use the datasets as an embedded dataset or shared dataset.

But in a real time, we mostly used embedded dataset for reports. Now, shared dataset is the mandatory option for SQL Server 2016 Reporting Services mobile reports.

There are plenty of articles available to show how to use the Shared Dataset for mobile report publisher. This article explains to you that how to create a shared dataset.

Shared dataset can be created any of the following tools.

  1. Visual Studio Data Tools
  2. Report Builder

Let us see the steps to create a shared dataset in Visual Studio Data Tools.

  1. Create a Reporting Services Project in Visual Studio
  2. Create a Shared Data source Connection under Solution Explorer
  3. Right Click on Shared dataset Folder and choose “Add New Dataset”
  4. Specify the name of the dataset and choose your data source.
  5. Under Query Type, you have 3 options. Text, Table & Stored Procedure. In our case, choose Text
  6. Pass your T-SQL Query. It can be simple or complex queries
  7. Make sure the query is correct and click Ok.
  8. Right click on your dataset and click deploy.
  9. Check the deployed dataset in datasets folder in report manager URL.

Let us discuss another scenario.

Scenario: Need to pass the parameter in shared dataset.

Follow the below steps,

  1. Add the parameter in your T-SQL Query as like below,

Where <columnname> = @<parametername>

In the above syntax, you can pass any condition as like regular T-SQL script. Instead of value pass parameter name with @ symbol.

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.
