How should I use an IDbConnection and an IDbTransaction with Dapper?
At the moment I am using only a IDbConnection
. Something as follows:
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Execute(@"insert Roles(Name) values (@name)", new { name = "Role" });
}
But sometimes I need to send 2 commands? Should I use BeginTransation
and EndTransaction
?
Yes, if you need two separate commands to be atomic and fail together, then you should use a transaction.
using (new TransactionScope(TransactionScopeOption.Required))
{
connection.Execute(...);
connection.Execute(...);
}
Or if you want to use BeginTransaction
and pass it in, you can also do:
using (var transaction = connection.BeginTransaction())
{
connection.Execute(sql1, params1, transaction);
connection.Execute(sql2, params2, transaction);
}
