Sqlbulkcopy 在浮点转换时出错 (asp.net c#)

Question

我正在尝试将 excel 的大部分内容插入到 sql

sqlBulk.WriteToServer(dReader); 给出错误

The given value of type String from the data source cannot be converted to type float of the specified target column.

我正在使用以下代码

 System.Data.SqlClient.SqlConnection strConnection;
    strConnection = new System.Data.SqlClient.SqlConnection("Data Source=L06DPSGCD0001;Initial Catalog=ProductionEfficiency;User ID=sample;Password=sample");

    string path = ("C:\Users\s3802616\Desktop\" + (FileUpload1.FileName));

    System.Diagnostics.Debug.WriteLine("C:\Users\s3802616\Desktop\" + (FileUpload1.FileName));
    string excelConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=" + "\"" + "Excel 12.0;HDR=YES;" + "\"";
    //Create Connection to Excel work book

    OleDbConnection excelConnection = new OleDbConnection(excelConnectionString);
    //Create OleDbCommand to fetch data from Excel

    OleDbCommand cmd = new OleDbCommand("Select [Model],[Process],[STD_Hours],[UOM],[Section] from [Sheet1$]", excelConnection);
    //OleDbCommand cmd = new OleDbCommand("Select * from [Sheet1$]", excelConnection);
    excelConnection.Open();
    strConnection.Open();
    OleDbDataReader dReader;
    dReader = cmd.ExecuteReader();
    SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection);
    //Give your Destination table name

    sqlBulk.DestinationTableName = "dbo.tblProcessStdHours";
    sqlBulk.WriteToServer(dReader);
    excelConnection.Close();
    strConnection.Close();
    lblStatus.Text = "Uploaded Successfully";

请建议。

Answer 1

错误说明了一切。

您正试图在 "float" 类型的目标列中复制 "string/chars"。

您需要将数据库 table "dbo.tblProcessStdHours" 中目标列的数据类型更改为 varchar。
