If your Windows 11 taskbar is not showing, you can try several troubleshooting steps to resolve the issue. Here are some potential solutions you can try:
The error message "Must declare the scalar variable '%.*ls'" typically occurs in SQL Server when you try to reference a variable that hasn't been declared or assigned a value yet.
To resolve this error, you need to declare the variable before you use it. Here's an example of how to declare a variable in SQL Server:
sqlDECLARE @myVariable VARCHAR(50)
In this example, we declare a variable named @myVariable of type VARCHAR with a maximum length of 50 characters. You can replace VARCHAR with a different data type depending on your requirements.
After declaring the variable, you can assign a value to it and use it in your SQL statement:
sqlSET @myVariable = 'Hello, world!'
SELECT @myVariable
This will set the value of @myVariable to 'Hello, world!' and then select that value, returning it as a result.
