mysql_table_name = 'clabDevelopment.KPI_kpireport'
mysql_cur = mysql_conn.cursor()
mysql_cur.execute('select * from %s where Date = "2018-01-01";' % mysql_table_name  )
description = mysql_cur.description
rows = mysql_cur.fetchall()

# Insert data into Redshift

redshift_cur.execute(insert_template % (redshift_table_name, column_names, values))
