MsSqlHelpers

MsSqlHelpers هي مكتبة لتحسين مهام التطوير الشائعة لـ MS SQL Server، مثل إنشاء إدراجات مجمعة ذات معلمات لاستخدامها مع ADO.NET وEntity Framework وDapper والمزيد (في المستقبل القريب).
للسماح بتشغيل IDENTITY INSERT، هناك معلمة اختيارية في استدعاء الأسلوب (الوضع الافتراضي OFF).

استخدام ADO.NET:

 using MsSqlHelpers ;

.. .

var mapper = new MapperBuilder < Person > ( )
    . SetTableName ( "People" ) // could be ommited if your table's name is the same as you entity's class name
    . AddMapping ( person => person . FirstName , columnName : "Name" )
    . AddMapping ( person => person . LastName , columnName : "Surename" )
    . AddMapping ( person => person . DateOfBirth ) // in this case property's name is the same as table column's name
    . Build ( ) ;
var people = new List < Person > ( )
{ 
    new Person ( ) { FirstName = "John" , LastName = "Lennon" , DateOfBirth = new DateTime ( 1940 , 10 , 9 ) } ,
    new Person ( ) { FirstName = "Paul" , LastName = "McCartney" , DateOfBirth = new DateTime ( 1942 , 6 , 18 ) } ,
} ;
var connectionString = "Server=SERVER_ADDRESS;Database=DATABASE_NAME;User Id=USERNAME;Password=PASSWORD;" ;
var sqlQueriesAndParameters = new MsSqlQueryGenerator ( ) . GenerateParametrizedBulkInserts ( mapper , people ) ;

using ( var sqlConnection = new SqlConnection ( connectionString ) )
{
    sqlConnection . Open ( ) ;
    
    // Default batch size: 1000 rows or (2100-1) parameters per insert.
    foreach ( var ( SqlQuery , SqlParameters ) in sqlQueriesAndParameters )
    {
        using ( SqlCommand sqlCommand = new SqlCommand ( SqlQuery , sqlConnection ) )
        {
            sqlCommand . Parameters . AddRange ( SqlParameters . ToArray ( ) ) ;
            sqlCommand . ExecuteNonQuery ( ) ;
        }
    }
}

استخدام إطار الكيان:

 using MsSqlHelpers ;

.. .

var mapper = new MapperBuilder < Person > ( )
    . SetTableName ( "People" ) // could be ommited if your table's name is the same as you entity's class name
    . AddMapping ( person => person . FirstName , columnName : "Name" )
    . AddMapping ( person => person . LastName , columnName : "Surename" )
    . AddMapping ( person => person . DateOfBirth ) // in this case property's name is the same as table column's name
    . Build ( ) ;
var people = new List < Person > ( )
{ 
    new Person ( ) { FirstName = "John" , LastName = "Lennon" , DateOfBirth = new DateTime ( 1940 , 10 , 9 ) } ,
    new Person ( ) { FirstName = "Paul" , LastName = "McCartney" , DateOfBirth = new DateTime ( 1942 , 6 , 18 ) } ,
} ;
var sqlQueriesAndParameters = new MsSqlQueryGenerator ( ) . GenerateParametrizedBulkInserts ( mapper , people ) ;

// Default batch size: 1000 rows or (2100-1) parameters per insert.
foreach ( var ( SqlQuery , SqlParameters ) in sqlQueriesAndParameters )
{
    _context . Database . ExecuteSqlRaw ( SqlQuery , SqlParameters ) ;
    // Depracated but still works: _context.Database.ExecuteSqlCommand(SqlQuery, SqlParameters);
}

استخدام أنيق:

 using MsSqlHelpers ;

.. .

var mapper = new MapperBuilder < Person > ( )
    . SetTableName ( "People" ) // could be ommited if your table's name is the same as you entity's class name
    . AddMapping ( person => person . FirstName , columnName : "Name" )
    . AddMapping ( person => person . LastName , columnName : "Surename" )
    . AddMapping ( person => person . DateOfBirth ) // in this case property's name is the same as table column's name
    . Build ( ) ;
var people = new List < Person > ( )
{ 
    new Person ( ) { FirstName = "John" , LastName = "Lennon" , DateOfBirth = new DateTime ( 1940 , 10 , 9 ) } ,
    new Person ( ) { FirstName = "Paul" , LastName = "McCartney" , DateOfBirth = new DateTime ( 1942 , 6 , 18 ) } ,
} ;
var connectionString = "Server=SERVER_ADDRESS;Database=DATABASE_NAME;User Id=USERNAME;Password=PASSWORD;" ;
var sqlQueriesAndDapperParameters = new MsSqlQueryGenerator ( ) . GenerateDapperParametrizedBulkInserts ( mapper , people ) ;

using ( var sqlConnection = new SqlConnection ( connectionString ) )
{
    // Default batch size: 1000 rows or (2100-1) parameters per insert.
    foreach ( var ( SqlQuery , DapperDynamicParameters ) in sqlQueriesAndDapperParameters )
    {
        sqlConnection . Execute ( SqlQuery , DapperDynamicParameters ) ;
    }
}
