php - 在我的 mysql 查询中无法正常工作的地方

Question

我的数据库中有 8 个表，我需要在一次查询中获取所有必要的数据。 当不使用 where 语句时，我的查询正常工作，但是当我在查询中使用 LIKE 和 OR LIKE 时，where 语句无法正常工作

我原来的查询是:

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_病人.status 时，返回不同的结果， 但是当我使用以下查询 mhr_ Patients.status 时，它不起作用，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

问题是什么？

Answer 1

您在查询中混合了 and 和 or。这基本上会否定你的 where 语句。您需要使用括号来对逻辑进行分组

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

您可能希望所有患者的状态均为 5，并且具有全名(如 %aaaa%)或国家代码(如 %aaa$ 等)。要实现此目的，您需要使用括号将您的 或 语句组合成一个单位。
