从字符串“从tblCustMst中选择CustName”到“Integer”类型的转换无效

Question

下面的代码在第二个语句中给出了转换异常。

Dim query As String = "select CustName from tblCustMst " & "where PlantId=@PlantId" 
cmd.CommandType = query 

Answer 1

您应该使用cmd.CommandText。
试试这个：

Dim query As String = "select CustName from tblCustMst " & "where PlantId=@PlantId" 
cmd.CommandText= query 

好运。
