我试图从asp.net
添加到sql表的行paremters sqlServer是:
[id] smallint IDENTITY (1, 1) NOT NULL ,
[purchaseNum] int NULL,
[purchaseDate] DateTime NULL,
[prodId] smallint NULL,
[amount] int NULL,
[price] decimal NULL,
[paidStatus] char NULL,
Primary key (id)
)
并且asp.net中的代码是:
private String BuildInsertCommand(Sale sale)
{
String command;
StringBuilder sb = new StringBuilder();
// use a string builder to create the dynamic string
sb.AppendFormat("Values('{0}', '{1}' ,'{2}', '{3}', '{4}','{5}', '{6}')", Convert.ToInt16(sale.ProductId), Convert.ToDateTime(sale.PurchaseDate), Convert.ToInt16(sale.ProductId), Convert.ToDecimal(sale.AmountOfItems),sale.TotalPrice, Convert.ToChar(sale.PaidStatus));
String prefix = "INSERT INTO sale " + "(purchaseNum, purchaseDate,prodId, amount, price,paidStatus) ";
command = prefix + sb.ToString();
return command;
}
我不明白为什么会出现错误消息,
感谢

您定义了7个占位符
{0}', '{1}' ,'{2}', '{3}', '{4}','{5}', '{6}'
你传递了6个参数
