input: Write a function to convert an SQL query into a Python program. The function should take a SQL query and a target year as input and return a function that, when called, executes the given SQL query with the specified where clause based on the target year. The SQL query should be executed on a specific database connection and print the results.
  
  assert convert_sql_query("SELECT * FROM orders", 2020)()
  
  The output of the function should be the same as the expected output for the given SQL query, which is a list of records from the "orders" table where the order_date is in the year 2020.
output: def convert_sql_query(sql_query, target_year):
      def execute_query():
          import sqlite3
          conn = sqlite3.connect('example.db')
          cursor = conn.cursor()
          query = f"{sql_query} WHERE strftime('%Y', order_date) = '{target_year}'"
          cursor.execute(query)
          results = cursor.fetchall()
          conn.close()
          print(results)
      return execute_query
