Here's an example of removing duplicate rows from a table using the DISTINCT keyword in SQL:n```sqlnSELECT DISTINCT column1, column2 FROM your_table; n```nTo add a new column, you can use the CAST or CONVERT functions to convert an existing column to a specific data type. For example, if you want to create a new column named 'NewColumn' with the first letter in uppercase from the existing 'column1':n```sqlnALTER TABLE your_table ADD NewColumn AS UPPER(column1); n```

Write the .net syntax for 'while loop'?
