sqlExecutor SnapObjects.Data.ISqlExecutor

An ISqlExecutor that can run SQL statements.

queryBuilder SnapObjects.Data.ISqlQueryBuilder

A SqlQueryBuilder object which can be used to generate a SQL SELECT statement.

Examples

The following code example demonstrates how to use the SelectToStore<TModel>(ISqlQueryBuilder, params Object[] method to generate and execute the SQL statement using a SqlQueryBuilder and place the query result to a ModelStore.

using Appeon.ApiDoc.Models.School;
using DWNet.Data;
using SnapObjects.Data;
using System;

namespace Appeon.ApiDoc.SqlExecutorExtensionsExamples
{
    public class SelectToStoreExample
    {
        private readonly SchoolContext _context;

        public SelectToStoreExample(SchoolContext dataContext)
        {
            // Sets the data context
            _context = dataContext;
        }

        public void Example3()
        {
            // Creates SqlQueryBuilder.
            var builder = new SqlQueryBuilder();

            // Defines the SQL statement.
            builder.Select("CourseID")
                   .Select("Title")
                   .From("Course");

            // Executes the SQL statement and puts the query result to a ModelStore.
            var ms = _context.SqlExecutor.Select<DynamicModel>(builder);

            Console.WriteLine("Records Count: {0}.", ms.Count);

            /*This code produces the following output:

            Records Count: 10.
            */
        }
    }
}
