string query = new MsSqlQueryGenerate<Country>()
        .GenerateInsertQuery();

+Output: "insert into dbo.Country (CountryName,Continent) values (@CountryName,@Continent)"

Insert Query For PostgreSql

string query = new NpgQueryGenerate<Country>()
        .GenerateInsertQuery();

+Output: "insert into dbo.Country (\"CountryName\",\"Continent\") values (@CountryName,@Continent)"

Country country = new() { CountryName = "TURKEY", Continent = "ASIA", Currency = "TRY" };
int row = await conn.ExecuteAsync(
    query,
    country);

Update

Update Query For MsSql

string query = new MsSqlQueryGenerate<Country>()
        .GenerateUpdateQuery();

+Output: "update dbo.Country set CountryName=@CountryName,Continent=@Continent where CountryId=@CountryId"

Update Query For PostgreSql

string query = new NpgQueryGenerate<Country>()
        .GenerateUpdateQuery();

+Output: "update dbo.Country set \"CountryName\"=@CountryName,\"Continent\"=@Continent where \"CountryId\"=@CountryId"

Using With Dapper

Country country = new() { CountryId = 1, CountryName = "TURKEY", Continent = "ASIA", Currency = "TRY" };
int row = await conn.ExecuteAsync(
    query,
    country);

Delete

Delete Query For MsSql

string query = new MsSqlQueryGenerate<Country>()

Select Query For MsSql

string query = new MsSqlQueryGenerate<Country>()
        .GenerateGetAllQuery();

+Output: "select CountryId as CountryId,CountryName as CountryName,Continent as Continent,Currency as Currency from dbo.Country order by CountryId"

Select Query For PostgreSql

string query = new NpgQueryGenerate<Country>()
        .GenerateGetAllQuery();
