Hi @shruti.garg

To retrieve one value from a database using UiPath, you can follow these general steps:

  1. Install Dependencies:
    Ensure you have the necessary packages installed in UiPath to interact with databases. UiPath usually includes the “UiPath.Database.Activities” package by default. If it’s not already installed, you can do so by going to “Manage Packages” in UiPath Studio.

  2. Establish Database Connection:
    You’ll need to establish a connection to the database you want to query. UiPath supports several databases like SQL Server, MySQL, Oracle, etc. The connection parameters will depend on the database you’re using.

  3. Query the Database:
    Use a SQL query to fetch the value you want from the database. Make sure you have the necessary permissions to read from the database. Your query should be designed to return a single value.

  4. Retrieve the Value:
    Once the query is executed, you’ll get the result, which is typically stored in a DataTable variable.

Here’s a step-by-step guide on how to achieve this:

Step 1: Open UiPath Studio and create a new automation project.

Step 2: Drag and drop the “Connect” activity from the “Database > Connect” category onto the workflow. Configure the database connection using the appropriate parameters (server name, credentials, database name, etc.).

Step 3: Drag and drop the “Execute Query” activity from the “Database > Execute Query” category onto the workflow.

Step 4: In the “Execute Query” activity properties, specify the SQL query to retrieve the value you want. For example:

SELECT column_name FROM table_name WHERE condition;

Step 5: Create a variable (e.g., outputValue) of the appropriate type (string, int, etc.) to store the result.

Step 6: Drag and drop the “Assign” activity from the “Programming > Assign” category onto the workflow.

Step 7: In the “Assign” activity properties, set the value of outputValue to the retrieved value. For example:

outputValue = Convert.ToString(yourDataTable.Rows(0)(0))

Step 8: Finally, close the database connection using the “Disconnect” activity from the “Database > Disconnect” category.

Step 9: Optionally, you can use the outputValue variable in your automation as needed.

Hope it works!!

Hi @shruti.garg

  1. Make sure you have the “UiPath.Database.Activities” package installed. You can install it from the “Manage Packages” section in UiPath Studio.
  2. Use the “Connect” activity to connect to your database. Configure the connection details, such as the database provider (e.g., SQL Server, MySQL), server name, database name, username, and password.
  3. Use the “Execute Query” activity to run the SQL query mentioned above. In the properties of the activity, set the “SQL” field to the appropriate query for your database.
  4. If you want to retrieve the result and use it later in your workflow, you can store the output in a DataTable variable using the “Output” property of the “Execute Query” activity.
  5. Finally, you can access the specific ID value in your DataTable variable if you need to use it later in your UiPath automation.

Use the below query in the Execute query activity.

SELECT TOP 1 id FROM your_table_name;

Or

SELECT id FROM your_table_name LIMIT 1;

Hope it helps!!

Hey @shruti.garg ,
You can use LinQ Query to take only first id

the solution using linq is
var id = data.Select(item => item.id).FirstOrDefault()
