Question

我正在使用ADO.NET框架使用 Powershell 所以我有一个数据集内部数据集编辑数据表然后尝试保存我得到以下错误，错误是在此行抛出

$Adapter.Update($Global:dtCalendars)

the exception message is the following:
*Exception calling "Update" with "1" argument(s): "The parameterized query '(@BudgetYear int,@StartDate date,@EndDate date,@IsActive bit,@Mo' 
expects the parameter '@StartDate', which was not supplied." - Line Number: 603

Here is my full Powershell script for saving datatable in sql table. 

$dtAdded = $Global:dtCalendars.GetChanges([System.Data.DataRowState]::Added)

$SQLConnection.Open()        
$Adapter = New-Object System.Data.SqlClient.SqlDataAdapter

if($dtAdded -ne $null) 
{
    $InsertQuery = 
@"
    INSERT INTO [Financials].[Calendars]
    ([BudgetYear],[StartDate],[EndDate],[IsActive],[ModifiedBy],[ModifiedOn])
    VALUES(@BudgetYear,@StartDate,@EndDate,@IsActive,@ModifiedBy,@ModifiedOn)
"@                                
    $Adapter.InsertCommand = New-Object System.Data.SqlClient.SqlCommand($InsertQuery,$SQLConnection)
    $Adapter.InsertCommand.CommandType = [System.Data.CommandType]::Text
    $Parameter = $Adapter.InsertCommand.Parameters.Add("@RowCount", [System.Data.SqlDbType]::Int , -1,"@@ROWCOUNT")
    $Parameter.Direction = [System.Data.ParameterDirection]::ReturnValue
    $Adapter.InsertCommand.Parameters.Add("@BudgetYear",[System.Data.SqlDbType]::Int,-1,"BudgetYear")
    $Adapter.InsertCommand.Parameters.Add("@StartDate",[System.Data.SqlDbType]::Date,-1,"StartYear")
    $Adapter.InsertCommand.Parameters.Add("@EndDate",[System.Data.SqlDbType]::Date,-1,"EndYear")
    $Adapter.InsertCommand.Parameters.Add("@IsActive",[System.Data.SqlDbType]::Bit,-1,"IsActive")
    $Adapter.InsertCommand.Parameters.Add("@ModifiedBy",[System.Data.SqlDbType]::NVarChar,-1,"ModifiedBy")
    $Adapter.InsertCommand.Parameters.Add("@ModifiedOn",[System.Data.SqlDbType]::DateTime,-1,"ModifiedOn")

}

$Adapter.Update($Global:dtCalendars)

谢谢

通过阅读错误消息，似乎参数@StartDate未在您的代码中传递。您可以传递此信息，但实际值可能为null。因此，在传递参数之前进行空检查，或确保@StartDate具有值。

为了解决这个问题，我首先要对参数@StartDate进行硬编码并尝试。
