我无法从连接到我正在选择删除的mysql表中删除记录。
我通过选择一个复选框并单击我网站上javascript表界面上的提交按钮来执行以下删除语句,该界面使用jos_fsdspremade.id作为其自动增量密钥和典型的删除ID。
DELETE jos_fsdscart.*
FROM jos_fsdscart
LEFT JOIN jos_fsdspremade ON jos_fsdscart.mfd = jos_fsdspremade.item_number
WHERE jos_fsdspremade.id = ( '<input name="jos_fsdspremade.id" multiple="y" />' ) AND jos_fsdscart.id4 = '<code type="user" />'
但没有从jos_fsdscart中删除任何内容。日志如下:
属性'id'的替换值为'61'
executeQuery [start:0,limit:0]'query1'()
查询代码:DELETE jos_fsdscart。* FROM jos_fsdscart LEFT JOIN jos_fsdspremade ON jos_fsdscart.mfd = jos_fsdspremade.item_number WHERE jos_fsdspremade.id =('')AND jos_fsdscart.id4 =''
如您所见,我正在尝试根据联接表中的选择从jos_fsdscart表中删除记录:
如果有帮助,这是我在javascript界面中选择的mysql查询:
SELECT
`<output name="jos_fsdspremade.owner_id" hidden="y" />`,
`<output name="jos_fsdspremade.id" title="FSDS" width="70" text="view" type="next" query="24" task="showResults" linktype="open" sizex="980" sizey="730" />`,
`<output name="jos_fsdspremade.item_number" title=".pdf" width="70" text="SAVE" type="link" url="/menumanager/images/pdf/%s.pdf" />` ,
`<output name="jos_fsdspremade.pic" title="Image" type="link" linktype="img" url="/menumanager/images/preman/%s" sizex="30" sizey="30" width="65" />`,
`<output name="jos_fsdspremade.title" title="Product Name" width="300" filter="y" />`,
`<output name="jos_fsdspremade.brand" title="Brand" width="300" filter="y" />`,
`<output name="jos_fsdspremade.manufacturer" title="Distributor" width="200" filter="y"/>`,
`<output name="jos_fsdspremade.product_type" width="200" filter="y"/>`
FROM jos_fsdspremade, jos_fsdscart
WHERE `published`=1 AND jos_fsdscart.mfd = jos_fsdspremade.item_number AND `id4` = '<code type="user" />'
ORDER BY `title`
答案 0 :(得分:0)
我非常怀疑你是否有一个mysql表,其构造方式是'id'设置为varchar,它将接受类似("jos_fsdspremade.id" multiple="y" )
的内容。
您需要从表单中获取ID(其中显示的ID是可选的)并将其传递给查询:
WHERE jos_fsdspremade.id = 1
或者如果你想做多重ID:
WHERE jos_fsdspremade.id in (1, 2, 3)
