    Description

      Since execute() and executemany() use the same callback for retrieving data, array_size needs to be cleared.

      Example:

      import mariadb

      connection= mariadb.connect(db="test")
      		 
       
      		 
      cursor= connection.cursor()
      		 
       
      		 
      cursor.execute("create temporary table t1 (a int, b int)")
      		 
       
      		 
      cursor.executemany("insert into t1 values (?,?)", [(1,2),(3,4)])
      		 
       
      		 
      cursor.execute("insert into t1 values (?,?)", (4,5))

      raises exception:
      mariadb.DataError: Can't access column number 1 at row 1
