Question

注意：此问题以前过于简单;附上的问题是为了更好地理解我的问题

我有一家名为t_shipment的公司的发货数据表。（部分）标题是acc_num，type_of_business，contract_exception，payment_status等。

我需要为其他部门的工作做一个回顾表。所以我使用CREATE TABLE创建了一个新表ship_recap。

CREATE TABLE ship_recap
(vol_lumber(int), vol_oil(int);)

然后我需要回顾从t_shipment到ship_recap的相关数据。我用了

 INSERT INTO ship_recap (vol_lumber)
 SELECT COUNT(acc_num) from t_shipment WHERE type_of_business = 'LMB' and (contract_exception = 'VALID' OR payment_status IS NOT NULL)
 INSERT INTO ship_recap (vol_oil)
 SELECT COUNT(acc_num) from t_shipment where type_of_business = 'OIL' and (contract_exception = 'VALID' OR payment_status IS NOT NULL);)

它跑了，但结果是：

 ____________________
|vol_lumber| vol_oil |
----------------------
|   150    |   NULL  |
|   NULL   |   230   |
----------------------

但我希望他们成为：

 ____________________
|vol_lumber| vol_oil |
----------------------
|   150    |   230   |
----------------------

我尝试使用

INSERT INTO ship_recap (vol_lumber, vol_oil)
(SELECT COUNT(acc_num) from t_shipment WHERE type_of_business = 'LMB' and (contract_exception = 'VALID' OR payment_status IS NOT NULL),
SELECT COUNT(acc_num) from t_shipment where type_of_business = 'OIL' and (contract_exception = 'VALID' OR payment_status IS NOT NULL);)

相同逻辑的排列（例如将逗号更改为分号或取出括号），但每次都返回语法错误。

结果/回顾表可能有多达20多个标题，其他查询也可能稍微复杂一些。我需要一种方法来正确地将SELECT / COUNT-ed数据插入到recap表中并将它们保存在一行中。

编辑：根据里诺的建议，我试过这个

 CREATE TABLE ship_recap (vol_OIL int,vol_LUM int,vol_BEV int,processed_OIL int,processed_LUM int,processed_BEV int);
 INSERT INTO ship_recap (vol_OIL, vol_LUM, vol_BEV, processed_OIL, processed_LUM, processed_BEV)
 SELECT
  COUNT(IF(type_of_business = 'OIL' and process_date = '2016-05-12', 1, NULL)),
  COUNT(IF(type_of_business = 'LUM' and process_date = '2016-05-12', 1, NULL)),
  COUNT(IF(type_of_business = 'BEV' and process_date = '2016-05-12', 1, NULL)),
  COUNT(IF(type_of_business = 'OIL' and process_date = '2016-05-12' and (contract_exception = ‘VALID’ OR payment_status IS NOT NULL), 1, NULL)),
  COUNT(IF(type_of_business = 'LUM' and process_date = '2016-05-12' and (contract_exception = ‘VALID’ OR payment_status IS NOT NULL), 1, NULL)),
  COUNT(IF(type_of_business = 'BEV' and process_date = '2016-05-12' and (contract_exception = ‘VALID’ OR payment_status IS NOT NULL), 1, NULL)) FROM t_shipment;

一旦我纠正了缺失的参数和括号，它就起作用了。

尝试以下sql，可能对您有所帮助;）

 CREATE TABLE ship_recap (vol_OIL int,vol_LUM int,vol_BEV int,processed_OIL int,processed_LUM int,processed_BEV int);
 INSERT INTO ship_recap (vol_OIL, vol_LUM, vol_BEV, processed_OIL, processed_LUM, processed_BEV)
 SELECT
  COUNT(IF(type_of_business = 'OIL' and process_date = '2016-05-12', 1, NULL)),
  COUNT(IF(type_of_business = 'LUM' and process_date = '2016-05-12', 1, NULL)),
  COUNT(IF(type_of_business = 'BEV' and process_date = '2016-05-12', 1, NULL)),
  COUNT(IF(type_of_business = 'OIL' and process_date = '2016-05-12' and (contract_exception = ‘VALID’ OR payment_status IS NOT NULL), 1, NULL)),
  COUNT(IF(type_of_business = 'LUM' and process_date = '2016-05-12' and (contract_exception = ‘VALID’ OR payment_status IS NOT NULL), 1, NULL)),
  COUNT(IF(type_of_business = 'BEV' and process_date = '2016-05-12' and (contract_exception = ‘VALID’ OR payment_status IS NOT NULL), 1, NULL)) FROM t_shipment;

将复数count（）查询结果插入表
