VersaTul.Data.MsSql 2.0.18

VersaTul Data MsSql

VersaTul Data MsSql is a C# library that provides the ability to quickly create database access objects, usable on Microsoft SQL Server databases. It is built on top of System.Data.Common and System.Data.SqlClient namespaces, and offers helper methods to easily call stored procedures or plain text SQL queries, and map the results into data objects. It also supports bulk insert operations using MsSql Bulk Copy functionality.

Installation

You can install VersaTul Data MsSql from NuGet using the following command:

PM> NuGet\Install-Package VersaTul.Data.MsSql -Version latest

Features

• Quickly create database access objects for MsSql databases
• Easily call stored procedures or plain text SQL queries
• Map the results into data objects using helper methods
• Perform bulk insert operations using MsSql Bulk Copy functionality
• Support for SqlServer SqlDbType.Structured data type

Usage

To use VersaTul Data MsSql, you need to register the factory for System.Data.SqlClient, set up the configuration for the database connection, and create an instance of SqlDataSource. Then you can use the methods of SqlDataSource to execute queries and commands, and process the results. You can also use the BulkCopy class to perform bulk insert operations.

Here is a simple example of using VersaTul Data MsSql to query and insert data from a MsSql database:

using Microsoft.SqlServer.Server;
using System.Data;
using System.Data.Common;
using System.Data.SqlClient;
using VersaTul.Configuration.Defaults.Sql;
using VersaTul.Data.MsSql;
using VersaTul.Data.MsSql.Contracts;
using VersaTul.Data.Sql;
using VersaTul.Data.Sql.Configurations;
using VersaTul.Utilities;
using VersaTul.Utilities.Contracts;
using SqlParameter = VersaTul.Data.MsSql.SqlParameter;

            DbProviderFactories.RegisterFactory("System.Data.SqlClient", SqlClientFactory.Instance);

            // Setup configuration for MsSqlServer Database quering
            var configSettings = new Builder().AddOrReplace(new[] {
                new KeyValuePair<string,object>("DemoDb", new ConnectionInfo("Server=127.0.0.1;Database=DemoDb;User Id=sa;Password=Secretdatabasepassword;","System.Data.SqlClient")),

                new KeyValuePair<string, object>("SqlDbConnectionName", "AdventureWorks2019") // default to AdventureWorks2019 database.
