更新
有时，当一个家庭从系统中被停用时，它可能包含不止一个人。在我的案例中，在 sql fiddle 中，household_id=12 的家庭有 3 个人。
我需要将这 3 个人的数据从 indiviudal 表中插入到 individual_history 表中，只需将 ind_action 字段更改为以下消息 HH 已被停用。
这是一个示例数据:
| individual_id | household_id | family_relation_id | marital_status_id | ind_lmms_id | ind_un_id | head_of_hh | ind_first_name_ar | ind_last_name_ar | ind_first_name_en | ind_last_name_en | ind_gender | dob | ind_status | ind_date_added | user_id | system_date |
|---------------|--------------|--------------------|-------------------|-------------|-----------|------------|-------------------|------------------|-------------------|------------------|------------|------------|------------|----------------------|---------|----------------------|
| 1 | 12 | 3 | 1 | 321 | (null) | no | u | x | (null) | (null) | Male | 2012-01-01 | Active | 2018-07-19T00:00:00Z | 1 | 2018-07-19T00:00:00Z |
| 2 | 12 | 1 | 2 | 123 | (null) | no | x | y | (null) | (null) | Female | 1998-03-05 | Active | 2015-03-05T00:00:00Z | 1 | 2015-03-05T00:00:00Z |
| 3 | 12 | 3 | 1 | 1234 | (null) | no | x | z | (null) | (null) | Female | 2004-04-05 | Active | 2018-04-11T00:00:00Z | 1 | 2018-04-11T00:00:00Z |
所有 3 个字段都应插入表 individual_history 并将 ind_action 设置为我在上面添加的注释。
我需要将 individual 表中的 SELECT 查询值插入到名为 individual_history 的表中。
这里是查询:
INSERT INTO individual_history
(individual_id,
household_id,
family_relation_id_history,
marital_status_id_history,
ind_lmms_id_history,
ind_un_id_history,
head_of_hh_history,
ind_first_name_ar_history,
ind_last_name_ar_history,
ind_first_name_en_history,
ind_last_name_en_history,
ind_gender_history,
dob_history,
ind_status_history,
ind_action,
ind_date_changed,
user_id,
system_date)
VALUES ((SELECT i.individual_id,
i.household_id,
i.family_relation_id,
i.marital_status_id,
i.ind_lmms_id,
i.ind_un_id,
i.head_of_hh,
i.ind_first_name_ar,
i.ind_last_name_ar,
i.ind_first_name_en,
i.ind_last_name_en,
i.ind_gender,
i.dob,
i.ind_status
FROM individual i
WHERE i.household_id = :hid),
'HH Status Changed to inactive',
(SELECT i.ind_date_added,
i.user_id
FROM individual i
WHERE i.household_id = :hid),
:systemDate)
正如您从查询中看到的，我将 SELECT 语句分成两部分，因为我想插入一个特定的 ind_action 消息，然后我将继续获取其他 2 个字段 date added 和 user_id。
systemDate 就是 now() 函数的结果。
我尝试使用 12 作为 hid 运行此查询，但收到以下错误:
1136 - Column count doesn't match value count at row 1
经过几次搜索，我 found that I should add parenthesis对于每个值。所以我将查询更改为:
INSERT INTO individual_history
(individual_id,
household_id,
family_relation_id_history,
marital_status_id_history,
ind_lmms_id_history,
ind_un_id_history,
head_of_hh_history,
ind_first_name_ar_history,
ind_last_name_ar_history,
ind_first_name_en_history,
ind_last_name_en_history,
ind_gender_history,
dob_history,
ind_status_history,
ind_action,
ind_date_changed,
user_id,
system_date)
VALUES ((SELECT i.individual_id,
i.household_id,
i.family_relation_id,
i.marital_status_id,
i.ind_lmms_id,
i.ind_un_id,
i.head_of_hh,
i.ind_first_name_ar,
i.ind_last_name_ar,
i.ind_first_name_en,
i.ind_last_name_en,
i.ind_gender,
i.dob,
i.ind_status
FROM individual i
WHERE i.household_id = 12),
( 'HH Status Changed to inactive' ),
(SELECT i.ind_date_added,
i.user_id
FROM individual i
WHERE i.household_id = 12),
( NOW() ))
还是报同样的错
我tried to count the number of fields我正在插入的与我正在选择的相比，它们是相同的(18 个字段)。
更新
我通过删除 VALUES 子句更改了查询:
INSERT INTO individual_history
(
individual_id,
household_id,
family_relation_id_history,
marital_status_id_history,
ind_lmms_id_history,
ind_un_id_history,
head_of_hh_history,
ind_first_name_ar_history,
ind_last_name_ar_history,
ind_first_name_en_history,
ind_last_name_en_history,
ind_gender_history,
dob_history,
ind_status_history,
ind_action,
ind_date_changed,
user_id,
system_date
)
SELECT i.individual_id,
i.household_id,
i.family_relation_id,
i.marital_status_id,
i.ind_lmms_id,
i.ind_un_id,
i.head_of_hh,
i.ind_first_name_ar,
i.ind_last_name_ar,
i.ind_first_name_en,
i.ind_last_name_en,
i.ind_gender,
i.dob,
i.ind_status
FROM individual i
WHERE i.household_id=12,
'HH Status Changed to inactive',
(
SELECT i.ind_date_added,
i.user_id
FROM individual i
WHERE i.household_id=12),
now()
我得到了以下错误:
1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use
near ' 'HH Status Changed to inactive', ' at line 10
请注意，两个表中字段的数据类型完全相同，individual_history 表包含一个自增主键。

最佳答案
对于您要尝试执行的操作，您不需要两个 SELECT。如果你想为 ind_action 使用一些特定的值，只需在你的选择中替换它，就像你对 now() 函数所做的一样:
INSERT INTO targetTable (col1, col2, col3, col4, colTime)
SELECT colA, colB, 'my specific string', colD, now()
FROM sourceTable WHERE colA = 12;
这里，col3 获取字符串，colTime now()。
关于MYSQL 在插入查询中使用多个选择返回列数与第 1 行的值数不匹配，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53315130/
