你好朋友//我有这2个代码用于简单的搜索，但它不起作用//你能帮我吗... SQL查询在PHPMYADMIN中工作正常。但是当我运行 php 代码时，它给了我这个错误 Unknown column 'a.orecid' in 'field list
这是recorddisplay.php的代码

这是我的数据库结构：
员工有 Staffid 和 unitid(fk)
单位有unitid
位置有 locid unitid(fk)
罪犯有criminid和locid（fk）
犯罪记录有 orecid、date 和 crimeid(fk)
按照要求：
当我回显查询时，当我选择犯罪记录时我得到了这个：
SELECT a.orecid, b.offenderid, e.staffname, a.date FROM `criminalrecord` a, offender b ,location c, unit d,staff e WHERE a.offenderid = b.offenderid AND b.locid = c.locid and c.unitid = e.unitid and `a.id` LIKE '%%'
当我选择 offenderrecord 时，我得到了这个：
SELECT a.orecid, b.offenderid, e.staffname, a.date FROM `offenderrecord` a, offender b ,location c, unit d,staff e WHERE a.offenderid = b.offenderid AND b.locid = c.locid and c.unitid = e.unitid and `a.id` LIKE '%%'
