IDbHelper

This interface is used to mark a class to be a database helper object. It is very useful if you would like optimize and override the default implementation of the library (i.e.: retrieving the list of fields, retrieving newly generated identity).

Methods

Below is the list of methods.

How to Implement?

You have to manually create a class that implements this interface.

public class OptimizedSqlServerDbHelper : IDbHelper
{
    public IEnumerable<DbField> GetFields(IDbConnection connection,
        string tableName,
        IDbTransaction transaction = null)
    {
        // Implementations for the GetFields() here
    }

    public object GetScopeIdentity(IDbConnection connection,
        IDbTransaction transaction = null)
    {
        // Implementations for the GetScopeIdentity() here
    }

    ...
}

Please see the more detailed implementations at Database Helper page.

You have to implement all the methods needed by this interface. With this, you have the full control of you helper object.

Usability

Once you have the database helper implemented in a customized class, you can use the DbHelperMapper class to map it in your target RDDMS data provider.

DbHelperMapper.Add(typeof(SqlConnection), new OptimizedSqlServerDbHelper(), true);

The library will then use your customized database helper in most of the extended methods of the DbConnection object.
