错误SQLSTATE [07002]：应用中的COUNT字段不正确，但直接在MS Access中测试时查询工作正常

编程问答 2022-08-14

问题描述

在我的代码中执行以下查询时遇到此错误，但是当直接在ms访问中对其进行测试时，该查询可以正常工作。

“错误sqlSTATE [07002]：COUNT字段不正确：-3010 [Microsoft] [ODBC Microsoft Access驱动程序]参数太少。预期为1。”

解决方法

尝试使用SQL本机“ Is Null”：

select top 50 
    MainOrder.OrderNumber,OrderComponent.ArticleNumber,SupplierOrderMain.*,IIf(InvoiceItems.Amount Is Null,InvoiceItems.Amount) AS expr1,IIF(Customer.CustomerName Is Null,'N/A',Customer.CustomerName) AS expr2

也许状态是保留字：

where ([Status] = 'Status 1' or [Status] = 'Status 2')
