Question

我的数据库中有8个表，我需要在一个查询中包含所有必需的数据。如果不使用where语句，我的查询就可以了，但是当我在查询中使用LIKE和OR LIKE时，where语句无法正常工作

我的原始查询是：

SELECT `mhr_patients`.`id`, 
`mhr_patients`.`fullName`, 
`mhr_patients`.`nationalCode`, 
`mhr_patients`.`age`, 
`mhr_patients`.`firstGCS`, 
`mhr_patients`.`fileNumber`, 
`mhr_patients`.`isUnKnown`, 
`mhr_patients`.`docDetail`, 
`mhr_patients`.`presentation`, 
`mhr_patients`.`appRegisterTime`, 
`mhr_patients`.`inspectorRegisterTime`, 
`mhr_patients`.`patientStatusDetail`, 
`mhr_patients`.`patientDetail`, 
`mhr_patients`.`status`, 
`docT`.`text` AS docText, 
`tolOp`.`name` AS tolOpName, 
`tolOp`.`color` AS tolOpColor, 
`tolOp`.`res1` AS tolOpTextColor, 
`pLog`.`breathing`, 
`pLog`.`bodyMovement`, 
`pLog`.`faceMovement`, 
`pLog`.`gag`, 
`pLog`.`cough`, 
`pLog`.`cornea`, 
`pLog`.`pupil`, 
`pLog`.`dollEye`, 
`pLog`.`secondGCS`, 
`pLog`.`sedation`, 
`pLog`.`inspector`, 
`pLog`.`status` As pLogStatus, 
`pLog`.`section`, 
`pLog`.`id` AS pLogId, 
`pLog`.`typeOfSection`, 
`pLog`.`lastUpdateTime`, 
`pLog`.`isTransfer`, 
`pLog`.`opu`, 
`hos`.`name` AS hosName, 
`mhr_opu`.`name` AS opuName, 
`mhr_opu`.`id` AS opuId, 
`mhr_states`.`name` AS cityName, 
`mhr_inspectors`.`name` AS insName 
FROM (`mhr_patients`) 
JOIN `mhr_doc` AS docT ON `docT`.`id` = `mhr_patients`.`doc` 
JOIN `mhr_tol_options` AS tolOp ON `tolOp`.`id` = `mhr_patients`.`patientStatus` 
JOIN `mhr_patients_log` AS pLog ON `pLog`.`pId` = `mhr_patients`.`id` AND pLog.id = (SELECT MAX(mhr_patients_log.id) FROM mhr_patients_log WHERE mhr_patients_log.pId = mhr_patients.id) 
JOIN `mhr_hospitals` AS hos ON `hos`.`id` = `pLog`.`hospital` 
JOIN `mhr_opu` ON `mhr_opu`.`id` = `pLog`.`opu` 
JOIN `mhr_states` ON `mhr_states`.`id` = `pLog`.`city` 
JOIN `mhr_inspectors` ON `mhr_inspectors`.`id` = `pLog`.`inspector` 
WHERE 
`mhr_patients`.`status` =  5 
GROUP BY `pLog`.`pId` 
ORDER BY `mhr_patients`.`inspectorRegisterTime` asc 
LIMIT 30

当我使用上面的查询时，结果是正确的，当我更改mhr_patients。status时，会返回不同的结果，但是，当我使用以下查询mhr_patients。status无效时，无论参数是什么都会给出一个结果

SELECT `mhr_patients`.`id`, 
`mhr_patients`.`fullName`, 
`mhr_patients`.`nationalCode`, 
`mhr_patients`.`age`, 
`mhr_patients`.`firstGCS`, 
`mhr_patients`.`fileNumber`, 
`mhr_patients`.`isUnKnown`, 
`mhr_patients`.`docDetail`, 
`mhr_patients`.`presentation`, 
`mhr_patients`.`appRegisterTime`, 
`mhr_patients`.`inspectorRegisterTime`, 
`mhr_patients`.`patientStatusDetail`, 
`mhr_patients`.`patientDetail`, 
`mhr_patients`.`status`, 
`docT`.`text` AS docText, 
`tolOp`.`name` AS tolOpName, 
`tolOp`.`color` AS tolOpColor, 
`tolOp`.`res1` AS tolOpTextColor, 
`pLog`.`breathing`, 
`pLog`.`bodyMovement`, 
`pLog`.`faceMovement`, 
`pLog`.`gag`, 
`pLog`.`cough`, 
`pLog`.`cornea`, 
`pLog`.`pupil`, 
`pLog`.`dollEye`, 
`pLog`.`secondGCS`, 
`pLog`.`sedation`, 
`pLog`.`inspector`, 
`pLog`.`status` As pLogStatus, 
`pLog`.`section`, 
`pLog`.`id` AS pLogId, 
`pLog`.`typeOfSection`, 
`pLog`.`lastUpdateTime`, 
`pLog`.`isTransfer`, 
`pLog`.`opu`, 
`hos`.`name` AS hosName, 
`mhr_opu`.`name` AS opuName, 
`mhr_opu`.`id` AS opuId, 
`mhr_states`.`name` AS cityName, 
`mhr_inspectors`.`name` AS insName 
FROM (`mhr_patients`) 
JOIN `mhr_doc` AS docT ON `docT`.`id` = `mhr_patients`.`doc` 
JOIN `mhr_tol_options` AS tolOp ON `tolOp`.`id` = `mhr_patients`.`patientStatus` 
JOIN `mhr_patients_log` AS pLog ON `pLog`.`pId` = `mhr_patients`.`id` AND pLog.id = (SELECT MAX(mhr_patients_log.id) FROM mhr_patients_log WHERE mhr_patients_log.pId = mhr_patients.id) 
JOIN `mhr_hospitals` AS hos ON `hos`.`id` = `pLog`.`hospital` 
JOIN `mhr_opu` ON `mhr_opu`.`id` = `pLog`.`opu` 
JOIN `mhr_states` ON `mhr_states`.`id` = `pLog`.`city` 
JOIN `mhr_inspectors` ON `mhr_inspectors`.`id` = `pLog`.`inspector` 
WHERE 
`mhr_patients`.`status` =  5 
AND `mhr_patients`.`fullName`  LIKE '%aaa%' 
OR  `mhr_patients`.`nationalCode`  LIKE '%aaa%' 
OR  `mhr_patients`.`fileNumber`  LIKE '%aaa%' 
OR  `mhr_patients`.`age`  LIKE 'aaa' 
OR  `mhr_patients`.`firstGCS`  LIKE 'aaa' 
OR  `mhr_patients`.`patientDetail`  LIKE '%aaa%' 
GROUP BY `pLog`.`pId` 
ORDER BY `mhr_patients`.`inspectorRegisterTime` asc 
LIMIT 30

有什么问题？

Answer 1

您在查询中混合了and和or。这基本上会否定你的where声明。您需要使用括号来分组逻辑

WHERE 
`mhr_patients`.`status` =  5 
AND 

(`mhr_patients`.`fullName`  LIKE '%aaa%'
OR  `mhr_patients`.`nationalCode`  LIKE '%aaa%' 
OR  `mhr_patients`.`fileNumber`  LIKE '%aaa%' 
OR  `mhr_patients`.`age`  LIKE 'aaa' 
OR  `mhr_patients`.`firstGCS`  LIKE 'aaa' 
OR  `mhr_patients`.`patientDetail`  LIKE '%aaa%' )
GROUP BY `pLog`.`pId` 
ORDER BY `mhr_patients`.`inspectorRegisterTime` asc 
LIMIT 30

您可能打算让所有状态为5的患者和全名（如％aaaa％）或nationalCode（如％aaa $等）。为此，您需要使用括号将您的或语句组合成一个单元。

Answer 2

您可能打算：

`mhr_patients`.`status` =  5 
AND (`mhr_patients`.`fullName`  LIKE '%aaa%' 
    ^ -- bracket here
OR  `mhr_patients`.`nationalCode`  LIKE '%aaa%' 
OR  `mhr_patients`.`fileNumber`  LIKE '%aaa%' 
OR  `mhr_patients`.`age`  LIKE 'aaa' 
OR  `mhr_patients`.`firstGCS`  LIKE 'aaa' 
OR  `mhr_patients`.`patientDetail`  LIKE '%aaa%' ) <-- close here

你想要status = 5 or a textual match。没有括号MySQL解释为statsus = 5 or textual match in fullName, or other textual match。

在我的mysql查询中没有正确工作
