Question

我正在尝试将DataGridView中的数据插入到oracle数据库中对于一个记录一切正常，但当DataGridView中有多行时，我收到以下错误消息：

ora-06550第1行第15栏：

请参阅pls-00306错误的参数数量或类型   'F_INS_ORDER_DATA'

ora-06550第1行第7列：

pl / sql语句被忽略

我试过

检查参数数量，但由于成功插入一条记录，它们没问题
没有错误类型的参数，但它们没问题，因为一条记录已成功插入
我检查了参数是否顺序错误但是也可以，因为一条记录成功插入

代码：

string connstr = @"Data Source=orcl; User Id=user; password=pwd;";

string insertcmdtxt = @"F_INS_ORDER_DATA";   

using (OracleConnection conn = new OracleConnection(connstr))
using (OracleCommand cmd = new OracleCommand(insertcmdtxt, conn))
{
    try
    {
        conn.Open();

        cmd.CommandType = CommandType.StoredProcedure;

        cmd.CommandText = insertcmdtxt;

        cmd.Parameters.Add(":vORDER_ID", OracleDbType.Int32, ParameterDirection.ReturnValue);

        foreach (DataGridViewRow Row in DGV_INVOICE.Rows)
        {
            cmd.Parameters.Add(new OracleParameter(":P_CUSTOMER_ID", OracleDbType.Int32)).Value     = TB_CUSTOMER_ID.Text;
            cmd.Parameters.Add(new OracleParameter(":P_ORDER_NOTE", OracleDbType.Varchar2)).Value   = TB_ORDER_NOTE.Text;

            cmd.Parameters.Add(new OracleParameter(":P_PRODUCT_ID", OracleDbType.Int32)).Value      = Row.Cells[DGV_INVOICE.Columns["DGV_PRODUCT_ID"].Index].Value;
            cmd.Parameters.Add(new OracleParameter(":P_UNIT_PRICE", OracleDbType.Int32)).Value      = Row.Cells[DGV_INVOICE.Columns["DGV_UNIT_PRICE"].Index].Value;
            cmd.Parameters.Add(new OracleParameter(":P_QUANTITY", OracleDbType.Int32)).Value        = Row.Cells[DGV_INVOICE.Columns["DGV_QUANTITY"].Index].Value;
            cmd.Parameters.Add(new OracleParameter(":P_DISCOUNT", OracleDbType.Int32)).Value        = Row.Cells[DGV_INVOICE.Columns["DGV_DISCOUNT"].Index].Value;
            cmd.Parameters.Add(new OracleParameter(":P_ORDER_STATUS", OracleDbType.Varchar2)).Value = '1';
            cmd.Parameters.Add(new OracleParameter(":P_ITEM_NOTE", OracleDbType.Varchar2)).Value    = Row.Cells[DGV_INVOICE.Columns["DGV_ITEM_NOTE"].Index].Value;
        }

        cmd.ExecuteNonQuery();

        TB_INVOICE_ID.Text = (cmd.Parameters[":vORDER_ID"].Value).ToString();
    }
    catch (Exception EX)
    {
        MessageBox.Show(EX.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
        return;
    }
}
}'

代码更新

在测试了以下朋友的建议之后

现在我没有收到任何错误，但是如果数据库中有多行我发现只插入一条记录

string connstr = @"Data Source=orcl; User Id=user; password=pwd;";
                string insertcmdtxt = @"F_INS_ORDER_DATA";  

                using (OracleConnection conn = new OracleConnection(connstr))
                using (OracleCommand cmd = new OracleCommand(insertcmdtxt, conn))
                {
                    try
                    {
                        conn.Open();

                        cmd.CommandType = CommandType.StoredProcedure;

                        cmd.CommandText = insertcmdtxt;

                        foreach (DataGridViewRow Row in DGV_INVOICE.Rows)
                        {
                            cmd.Parameters.Clear();

                            cmd.Parameters.Add(":vORDER_ID", OracleDbType.Int32, ParameterDirection.ReturnValue);

                            cmd.Parameters.Add(new OracleParameter(":P_CUSTOMER_ID", OracleDbType.Int32)).Value     = TB_CUSTOMER_ID.Text;
                            cmd.Parameters.Add(new OracleParameter(":P_ORDER_NOTE", OracleDbType.Varchar2)).Value   = TB_ORDER_NOTE.Text;

                            cmd.Parameters.Add(new OracleParameter(":P_PRODUCT_ID", OracleDbType.Int32)).Value      = Row.Cells[DGV_INVOICE.Columns["DGV_PRODUCT_ID"].Index].Value;
                            cmd.Parameters.Add(new OracleParameter(":P_UNIT_PRICE", OracleDbType.Int32)).Value      = Row.Cells[DGV_INVOICE.Columns["DGV_UNIT_PRICE"].Index].Value;
                            cmd.Parameters.Add(new OracleParameter(":P_QUANTITY", OracleDbType.Int32)).Value        = Row.Cells[DGV_INVOICE.Columns["DGV_QUANTITY"].Index].Value;
                            cmd.Parameters.Add(new OracleParameter(":P_DISCOUNT", OracleDbType.Int32)).Value        = Row.Cells[DGV_INVOICE.Columns["DGV_DISCOUNT"].Index].Value;
                            cmd.Parameters.Add(new OracleParameter(":P_ORDER_STATUS", OracleDbType.Varchar2)).Value = '1';
                            cmd.Parameters.Add(new OracleParameter(":P_ITEM_NOTE", OracleDbType.Varchar2)).Value    = Row.Cells[DGV_INVOICE.Columns["DGV_ITEM_NOTE"].Index].Value;
                        }

                        cmd.ExecuteNonQuery();                        

                        TB_INVOICE_ID.Text = (cmd.Parameters[":vORDER_ID"].Value).ToString();
                    }
                    catch (Exception EX)
                    {
                        MessageBox.Show(EX.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
                        return;
                    }
                }

从DataGridView读取数据并插入到oracle数据库
