Question: Is there a way to setup/define dynamic parameter as in Dapper?

I’ve got RAW SQL + expando object with parameters list and in the database field that I’m looking for is of type VARCHAR(200) and my string parameter is parsed by repoDB to NVARCHAR(XXX) which causes slow performance when querying data.

I mitigate this issue by using:

            var @params = new
            {
                Id = id
            };

            TypeMapper.Add<string>(DbType.AnsiString);
            var data = await connection.ExecuteQueryMultipleAsync(query, @params);
            TypeMapper.Remove<string>();

but I’d rather to have something like in dapper:

var parameters = new DynamicParameters();
var customerId = "ALFKI";
parameters.Add("@CustomerId", customerId, DbType.String, ParameterDirection.Input, customerId.Length);
var sql = "select * from customers where CustomerId = @CustomerId";
using (var connection = new SqlConnection(connString))
{
    var customer = connection.QuerySingle<Customer>(sql, parameters);
}

Is it doable in the repodb? Can we select datatype for a query parameters?

That would work. We will look on this enhancement request afterwards.

Unfortunately using classes and no raw SQL is not an option in the company that I’m working in. I will create enhancement request for QueryField datatype parameter possibility.
