Operand should contain 1 column(s)

執行sql：

INSERT INTO user_info(name, age) VALUES (( SELECT u.name FROM user_info u where u.id = 4), 10)

操做成功

執行sql：

INSERT INTO user_info(name, age) VALUES (( SELECT u.name,u.age FROM user_info u where u.id = 4))

報錯

[SQL] INSERT INTO user_info(name, age) VALUES (( SELECT u.name,u.age FROM user_info u where u.id = 4))

[Err] 1241 - Operand should contain 1 column(s)

問題insert into（c1,c2…… c10） values （v1，v2, (select c3,c4……，c9) from table where 1=1), v10 ）,
（v1，v2, (select c3,c4……，c9) from table where 1=1), v10 ）,
（v1，v2, (select c3,c4……，c9) from table where 1=1), v10 ）
