Timeout for OracleDataReader.Read Method

由 浪子不回头ぞ 提交于 2019-11-28 12:10:41
The ODP.NET OracleCommand class has a CommandTimeout property that can be used to enforce a timeout for the execution of a command. This property seems to work in situations where the CommandText is a SQL statement. The example code is used to illustrate this property in action. In the initial version of the code, the CommandTimeout is set to zero - telling ODP.NET not to enforce a timeout. using System; using System.Collections.Generic; using System.Data; using System.Diagnostics; using System.Linq; using System.Text; using Oracle.DataAccess.Client; namespace ConsoleApplication3 { class

Oracle.DataAccess.Client Dependencies

First of all, I want to use the Oracle.DataAccess.dll to use OracleBulkCopy . I want to know all the dlls that I need to be able to read from a database and then perform a bulkcopy in Oracle. Currently, we are using only one dll to perform all the reads from databases, we are using Oracle.ManagedDataAccess.Client . But I can't use it to perform a bulkCopy. I don't want to install ODP.NET for the users, I want to include the dll directly in the program. So I want to know the minimum required dlls to be able to use the Oracle.DataAccess.dll in 32bit and in 64bit. I know that there are some old

Oracle ODP.Net and EF CodeFirst - SaveChanges Error

问题 Could someone help me with this: The code: Role r = new Role { ID = 1, Name = "Members" }; ctx.Roles.Attach(r); //Saving User User u = new User { Login = login, Password = password, Status = 1 }; u.Roles.Add(r); ctx.Users.Add(u); ctx.SaveChanges(); What I'm trying to do is to save a new user with an existing role. User and Role classes have a many-to-many relationship mapped by fluent-api as follows: modelBuilder.Entity<User>() .HasMany(u => u.Roles) .WithMany(r => r.Users) .Map(x => { x

Binding query parameters by name with ODP.NET

由 人走茶凉 提交于 2019-11-28 09:46:45
I'm currently using the Microsoft ADO.NET provider for Oracle ( System.Data.OracleClient ). I'm aware that it is certainly not the best Oracle provider available and that it will soon be deprecated , I should be using Oracle's ODP.NET instead. The reason why I still use the MS provider is because ODP.NET binds parameters by position , not by name. This can really be a PITA when you use many parameters in a query, because you have to be careful to add them in the right order, which can easily lead to bugs. It's also annoying when you use the same parameter multiple times in the same query, for
