t sql dynamic top n query 1

t sql dynamic top n query

SELECT TOP (@top) * FROM tablename;

Here is what the above code is Doing:
1. We’re creating a variable called top, and setting it equal to the number of rows we want to return.
2. We’re creating a variable called query, and setting it equal to a string that contains our SQL query.
3. We’re using the .format() method to insert the value stored in top into the SQL query.
4. We’re executing the query using the .execute() method, and passing it our query variable.
5. Finally, we’re using the .fetchall() method to return our results as a list of tuples.
