更新部分的代码不执行
//根据出库量更新库存public static void UpdateMedicineSumByOut(int MedicineID,int MedicineSum)
{
DbCommand comm = GenericDataAccess.CreateCommand(CommandType.StoredProcedure);
comm.CommandText = "UpdateMedicineSum";
DbParameter parm;
parm = comm.CreateParameter();
parm.ParameterName = "@MedicineID";
parm.DbType = DbType.Int32;
parm.Value = MedicineID;
comm.Parameters.Add(parm);
parm = comm.CreateParameter();
parm.ParameterName = "@MedicineSum";
parm.DbType = DbType.Int32;
parm.Value = MedicineSum;
comm.Parameters.Add(parm);
}
存储过程名为UpdateMedicineSum
这是后台执行代码：
protected void Btn_Submit_Click(object sender, EventArgs e)
{
DataTable dt = CatalogAccess.GetMedicineInfoByDrugname(txtdrugname.Text);
int MedicineID = Convert.ToInt32(dt.Rows[0]["MedicineID"]);
int MedicineSumNow = Convert.ToInt32(dt.Rows[0]["MedicineSum"]);
int MedicineSumUpdate = MedicineSumNow - Convert.ToInt32(txtsum.Text);
CatalogAccess.UpdateMedicineSumByOut(MedicineID, MedicineSumUpdate);
if (CatalogAccess.AddGiveOutRecord(txtdepartment.Text,MedicineID,Int32.Parse(txtsum.Text),Convert.ToDouble(txtindprice.Text),Convert.ToDateTime(DateTime.Now)))
{
ltScript.Text = "<script type='text/javascript'>alert('添加成功');</script>";
return;
}
}
更新那句代码没有执行。。。

return;

}
是它不执行么 ?

断点进不去。。。 --------------------编程问答--------------------
数据库里没有任何反应。。。 --------------------编程问答-------------------- 试试版主的回答吧...
