InternalError：（1242 'サブクエリが1行以上を返す'）

Question

このコード

conn = pymysql.connect(user = 'root', password = '', unix_socket = "/tmp/mysql.sock", database = 'abc') 
cursor = conn.cursor() 
query2 = """INSERT INTO paragraphVector (termId, termFreq, kgram) VALUES ((SELECT termId FROM term WHERE term = %s AND kgram = %s), %s, %s)""" 

insertDocVec = [(str(term), str(kgram), tf[kgram][term], str(kgram)) for kgram in tf for term in tf[kgram]] 
cursor.executemany(query2, insertDocVec) 
conn.commit() 

Answer 1

変更を実行するときに内部エラーを取得するこの：これに

INSERT INTO paragraphVector (termId, termFreq, kgram) VALUES ((SELECT termId FROM term WHERE term = %s AND kgram = %s), %s, %s) 

：

INSERT INTO paragraphVector (termId, termFreq, kgram) SELECT termId, %s, %s FROM term WHERE term = %s AND kgram = %s 

と最後の2つのパラメータを左に移動

Answer 2

文が間違っています。試してください：

INSERT INTO paragraphVector (termId, termFreq, kgram) 

SELECT termId , %s, %s 

FROM term WHERE term = %s AND kgram = %s
