In the query pane, type the following T-SQL code after the previous code: int = nvarchar(20) In the query pane, type the following T-SQL code: int = nvarchar(20) Also, keep in mind that GO is a client command, not a server T-SQL command. If you try to refer to a variable that was defined in another batch, you get an error saying that the variable wasn’t defined. Must declare the scalar variable “ are local to the batch in which they’re defined. Make sure your T-SQL code looks like this: int Now, in the code you just copied, add the batch delimiter GO before this statement: SELECT AS employee Highlight the written T-SQL code and Select ⏵Run.Ĭhange the variable’s value from 5 to 2 and execute the modified T-SQL code you’ll get: employee.SET = (SELECT FirstName + N' ' + LastName FROM SalesLT.Customer WHERE CustomerID = AS employee In the query pane, type the following T-SQL code: int Right click on the TSQL connection and select New Query.Now, we’ll look at how to declare variables in batches. You’ve now seen how to declare variables and how to retrieve values. Highlight the written T-SQL code and select ⏵Run.In the query pane, type the following T-SQL code after the previous one: int Highlight the above T-SQL code and select ⏵Run.In the query pane, type the following T-SQL code: DECLARE int = 5 The previous step will open a query screen that is connected to the adventureworks database.A new query window is displayed with a connection to the AdventureWorks database. Right click on the AdventureWorks connection and select New Query.A green dot will appear when the connection is successful. From the Servers pane, double-click the AdventureWorks connection.Note: If you’re familiar with the standard AdventureWorks sample database, you may notice that in this lab we are using a simplified version that makes it easier to focus on learning Transact-SQL syntax. For your reference, the following diagram shows the tables in the database (you may need to resize the pane to see them clearly). In this lab, you’ll use get an introduction to programming using T-SQL techniques using the adventureworks database.
