SELECT Sum(gross_motor + visual_motor_skills
+ draws_a_person + prints_personal_data)
FROM brigance_screening_term0 AS T0
WHERE year = 2011
AND Str_to_date(date, '%Y-%m-%d') = 2016 - 05 - 11
LIMIT 1
最佳答案
你好像有错字
AND Str_to_date(date, '%Y-%m-%d') = 2016 - 05 - 11
应该是
AND Str_to_date(date, '%Y-%m-%d') = '2016-05-11'
