Dynamic Query

Utility library for build data query descriptor or convert it to Linq Expression or SQL Statements. Here is a sample

DynamicQueryBuilder builder = DynamicQueryBuilder.Create(true);
var child1 = builder.ParamGroupBuilder.CreateChildAndGroup();
child1.ParamBuilder.Any("Extra", sub =>
{
    sub.ParamBuilder.Equal("Guest", "Andy");
});
var child2 = builder.ParamGroupBuilder.CreateChildOrGroup()
            .ParamBuilder
                .Contains("Address", "chengdu")
                .EndsWith("Address", "lnk")
                .Equal("Disabled", false)
                .GreaterThan("Amout", 10)
                .GreaterThanOrEqual("Price", 100)
                .In("Drink", "mileshake,coffee")
                .LessThan("Count", 10)
                .LessThanOrEqual("Total", 100)
                .StartsWith("Url", "Http://");
builder.OrderBy("Amout", ListSortDirection.Ascending)
    .Select("Guest").Take(10).Skip(10);
var dynamicQuery = builder.Build();

LinqBuilder

DynamicQuery-LinqExpression Converter.

SqlBuilder

STEP 1 : Add SqlBuilder Services in `StartUp.cs`

 public void ConfigureServices(IServiceCollection services)
{
   services.AddSQLBuilder(opts =>
   {
      opts.UseMySQL();
   });
}

STEP 2 : Builder mapping data with fluent style api

var mappings = new SqlFieldMappings();
mappings.Map("Guest", "t1.Guest")
        .Map("Address", "t1.Address")
        .Map("Disabled", "t1.Disabled")
        .Map("Amout", "t1.Amout")
        .Map("Price", "t1.Price")
        .Map("Drink", "t1.Drink")
        .Map("Count", "t1.Count")
        .Map("Total", "t1.Total");
// Native api also be supported
mappings.Add("Url", "t1.Url");

STEP 3 : Builder SQL clauses

// `selectBuilder` should be injected from DI. Notice it's lifetime and create service scope any time if	necessary.
selectBuilder.Mapping(mappings);
selectBuilder.Where(dynamicQuery.ParamGroup);
var whereClause = selectBuilder.BuildWhere();
var orderbyClause = selectBuilder.OrderBy(dynamicQuery.Order);

** In this case, value of whereClause is :

((Extra.Guest = @PARAM_0)) AND (t1.Address like @PARAM_1 OR t1.Address like @PARAM_2 OR t1.Disabled = @PARAM_3 OR t1.Amout > @PARAM_4 OR t1.Price >= @PARAM_5 OR t1.Drink IN (mileshake,coffee) OR t1.Count < @PARAM_6 OR t1.Total <= @PARAM_7 OR t1.Url like @PARAM_8)
