我正在使用 ADO.NET、C# 将值从 Webform 插入到数据库中。我使用的数据库是 Oracle 数据库。没有插入值,程序在 cmd.ExecuteNonquery() 处被击中
下面是我的代码,如果我做错了,请告诉我..我正在使用一些静态方法会有什么问题吗?..
public Boolean AddDivCo(Int32 UserNo,String ID, String Role, String DivName )
{
Boolean ret = false;
OracleCommand cmd = new OracleCommand();
OracleConnection conn = new OracleConnection();
int i = 0;
try
{
conn.ConnectionString = ConfigurationManager.ConnectionStrings["Conn_RIS"].ConnectionString;
conn.Open();
cmd.Connection = conn;
String mySQL = "INSERT INTO R4CAD_ADMIN (AdminUserNo, AdminID, AdminRole, AdminDivName)VALUES(:AdminUserNo,:AdminID,:AdminRole,:DivName)";
OracleParameter p1 = new OracleParameter("AdminUserNo", OracleType.Number);
p1.Value = UserNo;
cmd.Parameters.Add(p1);
OracleParameter p2 = new OracleParameter("AdminID", OracleType.VarChar);
p2.Value = ID;
cmd.Parameters.Add(p2);
OracleParameter p3 = new OracleParameter("AdminRole", OracleType.VarChar);
p3.Value = Role;
cmd.Parameters.Add(p3);
OracleParameter p4 = new OracleParameter("DivName", OracleType.VarChar);
p4.Value = DivName;
cmd.Parameters.Add(p4);
cmd.CommandText = mySQL;
i = cmd.ExecuteNonQuery();
if (i != 0)
{
ret = true;
}
else
{
ret = false;
}
}
catch (Exception err)
{
Console.WriteLine(err.Message.ToString());
}
finally
{
cmd.Dispose();
//cmd = null;
//conn = null;
conn.Close();
}
return ret;
}
