这里的数组项应该是$x['scanners.BundleNumber']。您是否尝试返回生成的SQL字符串，然后手动测试该字符串？我在第一个数组上执行了var_转储，它返回一个空数组。在sql server上运行的sql与这两个类都匹配。foreach$scanner作为$x{$sql.=$x.，；}将生成无效的sql片段，因为IN值的提升将以逗号结束。将0添加到$scanner数组中，然后使用内爆“，”，$scanner；相反另外，$scanner数组的内容被正确转义了，对吗？哦，还有一点关于编码风格的建议，您的函数太长了，乍一看似乎运行4或5个SQL查询。这么大的函数往往不是个好主意，因为它们更难维护或重用。作为一个一般的经验法则，我喜欢应用，如果一个函数/方法在我的IDE中不仅仅是一屏文本，那么它向我表明应该分解它。此外，DB查询函数应该运行1个查询，并且只能运行1个查询。每个查询包含一个操作，代码中的每个函数只能执行一个任务。我不明白这一点。你能举个例子吗？使用一个好的编辑器有助于防止这种错误。从ActiveState尝试Komodo IDE-有一个免费版本可用。
