![]() ![]() What else can I do to get the EF from timing out? This only happens for very large datasets. I tried setting the CommandTimeout in my repository directly like so: private TrekEntities context = new TrekEntities() This is what my connection string looks like: ![]() I added Default Command Timeout=300000 to the connection string in the App.Config file in the project that has the EDMX file as suggested here. I tried the following and have not been able to resolve this issue: By using these techniques, you can ensure that your code runs smoothly and efficiently, even when working with large amounts of data.I am getting timeouts using the Entity Framework (EF) when using a function import that takes over 30 seconds to complete. Dapper provides several ways to handle these exceptions, including setting the timeout value on individual queries and intercepting command executions to set the timeout value. Handling CommandTimeout exceptions is an important consideration when working with databases, particularly when dealing with large amounts of data. The results are mapped to the Company class and returned as a list of companies. The commandTimeout parameter of the QueryMultipleAsync method ensures that the query is aborted if it takes longer than the specified timeout value. It then sets a timeout TimeoutInSeconds on the connection and executes the query using the QueryMultipleAsync method. This method fetches a list of companies from the database using a connection without a timeout. Var companies = await multipleResult.ReadAsync() Var multipleResult = await connection.QueryMultipleAsync(query, commandTimeout: TimeoutInSeconds) Using var connection = _context.CreateConnectionWithoutTimeout() NET/C# content and get paid? > JOIN US! > GetCompaniesWithTimeoutInInQueryMultiple() Wanna join Code Maze Team, help us produce more awesome. So we should be sure to set it back to the default value if we only need a custom timeout for a specific query or operation. Note that this setting applies to all subsequent queries that use Dapper until it is changed again. This will cause Dapper to wait for up to 50 seconds for the SQL command to complete before timing out and throwing an exception. One of these settings is the CommandTimeout property, which specifies the amount of time that Dapper should wait for a SQL command to complete before timing out.įor example, if we want to set a command timeout of 50 seconds for a specific query: In Dapper, the SqlMapper class provides a variety of settings that can be configured to control various aspects of how Dapper operates. In this case, we have set it to 5 seconds. The Connection Timeout specifies the wait time in seconds before the database connection throws an error due to the lack of response. User Id=your_user Password=your_password Application Name=DapperASPNetCore TrustServerCertificate=True "SqlConnectionWithTimeout": "server=your_server Integrated Security=false database=DapperASPNetCore The connection string typically includes parameters such as the server name, database name, user ID, and password: We use this file to store configuration settings for the application, including database connection information. NET Core application, the first step is to define a connection string in the appsettings.json file. Here are some ways to configure CommandTimeout in Dapper: Setting CommandTimeout in Connection String EntitiesĪfter the installation, we are going to create a Company entity in the Model folder: public class CompanyĪnd the Employee entity in the same folder: public class Employee If you want to learn how to use the FluentMigrator library to create data migrations with Dapper and ASP.NET Core you can read our article on that topic. ![]() FluentMigrator – PM> Install-Package FluentMigrator.Runner. ![]()
