EFCore 3.0 Devart Provider With OracleDB doen't work raw sql

Question

My project run on .net core 3.1, I use data provider Devart.Oracle also my project data stores on OracleDB 11g

My problem when i try to get sequence with EFCore V3.0 like that;

using (TransactionScope scope = new TransactionScope())
            {
              _dbcontext.TABLEs.Add(values);
              var _sqlseq = string.Format(@"PACKAGE.MY_TABLE_SEQ");
              _dbcontext.TABLEs.FromSql(_sqlseq).FirstOrDefault();
              _dbcontext.SaveChanges();
              scope.Complete();
            }

Also I tried FromSqlRaw but i didn't take any result and idea ?

Answer 1

I updated my project packages like as below

EF Core 3.1.6 Devart 9.10.1054 versions then now i can run that query

var sql = string.Format(@"A TABLE QUERY");
 var result = _dbcontex.TABLESs.FromSqlRaw(sql).First();

Also i have another solition for run pure sql in .netcore projects

if you can use Dappet which is avalible for run pure sql framework like this,

var conn = this.GetConnection(_connectionString); // dapper connect DB with  connection string
        result = SqlMapper.Query<dynamic>(conn, query, null, commandType: CommandType.Text).First();
        conn.Close();
