Nexd.MySQL 1.0.2

C# Sync & Async MySQL (MySqlConnector library) Wrapper

Installation

Available on NuGet

dotnet add package Nexd.MySQL --version 1.0.2

Initialization

// import using
using Nexd.MySQL;

MySqlDb MySql = new MySqlDb("localhost", "root", "password", "database");

ExecuteQuery & ExecuteNonQuery usage (unsafe)

These functions are not safe in the context of SQL injection. Make sure to escape your values correctly before executing. (MySqlHelper.EscapeString(value);)

MySql.ExecuteQuery($"SELECT * FROM `Players` WHERE Name = '{name}';", name); make sure that the name is escaped.

MySql.ExecuteNonQuery("DELETE * FROM `Players`;");

Where condition

// WITH WRAPPER CLASSES
MySqlQueryCondition conditions = new MySqlQueryCondition()
    .Add("ID", ">", "1002")
    .Add("ID", "<=", "1008");

MySqlQueryResult result = MySql.Table("players").Where(conditions).Select();
for(int i = 0; i < result.Rows; i++)
{
    Console.WriteLine($"{result.Get<int>(i, "ID")} {result.Get<string>(i, "Name")} {result.Get<string>(i, "Identifier")}");
}

// WITHOUT
MySqlQueryResult result = MySql.Table("players").Where("ID > 1002 AND ID <= 1008").Select();
for(int i = 0; i < result.Rows; i++)
{
    Console.WriteLine($"{result.Get<int>(i, "ID")} {result.Get<string>(i, "Name")} {result.Get<string>(i, "Identifier")}");
}

Insert Query

MySqlQueryValue values = new MySqlQueryValue()
    .Add("Name", "Player Name #1") // DB column is 'Name', insert data 'Player Name #1'
    .Add("Identifier", "uniqueidentifier"); // DB column is 'Identifier', insert data 'uniqueidentifier'

// assume there is a table named 'players'
MySql.Table("players").Insert(values);

Update Query

MySqlQueryValue values = new MySqlQueryValue()
    .Add("Name", "Player Name #2");

// with wrapper classes
int rowsAffected = MySql.Table("players").Where(MySqlQueryCondition.New("Identifier", "=", "uniqueidentifier")).Update(values);

// without
int rowsAffected = MySql.Table("players").Where("Identifier = 'uniqueidentifier'").Update(values);
int rowsAffected = MySql.Table("players").Where("Identifier = 'uniqueidentifier' AND ID > 0").Update(values); // random example that shows you can define your where statement just as you like

Select Query

// with wrapper classes
MySqlQueryResult result = MySql.Table("players").Where(MySqlQueryCondition.New("Identifier", "=", "uniqueidentifier")).Select();

// without
MySqlQueryResult result = MySql.Table("players").Where("Identifier = 'uniqueidentifier'").Select(); // you can specify the fields (columns) you want to select, also LIMIT the amount of results by passing them to the .Select() as parameters

// then
int playerId = result.Get<int>(0, "ID"); // 0 is the row, "ID" is the column name in the results
DateTime registeredAt = result.Get<DateTime>(0, "CreationDate"); // 0 is the row, "CreationDate" is the column name in the results

Delete Query

// with wrapper classes
int rowsAffected = MySql.Table("players").Where(MySqlQueryCondition.New("Identifier", "=", "uniqueidentifier")).Delete();

// without
int rowsAffected = MySql.Table("players").Where("Identifier = 'uniqueidentifier'").Delete();

Async

Note: that every method has its Async version implemented

Documentation is currently unavailable, but its self explanatory and has the same syntax with the sync version, just with Async method names.
