SearchLib

SearchLib is a C# library designed to search JSONB data stored in PostgreSQL tables. It allows users to perform dynamic SQL queries on specific JSON keys and values, supporting various data types such as numerical, string, boolean, and arrays. It also enables querying with multiple conditions, making it a flexible solution for working with JSONB data in PostgreSQL.

Features

  • Dynamic JSON Key Search: Query JSONB columns for specific keys and values.
  • Supports Multiple Data Types: Handles numerical, string, boolean, and array data types.
  • Dynamic SQL Query Generation: Automatically generates the correct SQL based on the provided conditions.
  • Multiple Conditions: Allows querying multiple JSON keys at once, applying conditions like comparison operators.

Installation

Add the SearchLib class to your project and ensure you have the following dependencies:

  • .NET Framework: Ensure your project is using .NET 5 or higher.
  • Npgsql: A PostgreSQL data provider for .NET. Install it via NuGet:
dotnet add package Npgsql


## Usage

### 1. Initialize the Library

First, initialize the `SearchLib` class by passing your PostgreSQL connection string:

```csharp
string connectionString = "Host=my_host;Port=5432;Username=my_user;Password=my_pw;Database=my_db";
var searchLib = new SearchLib(connectionString);


### 2. Searching Multiple JSON Keys

To search for multiple conditions on JSON keys, use the `SearchMultipleJsonKeys` method. Pass the table name, column name, and a dynamic array of conditions.

Each condition must contain the `JsonKey`, `ExpectedValue`, and `Operand`.

#### Example:

```csharp
dynamic conditions = new[] {
    new { JsonKey = "fps", ExpectedValue = 30, Operand = ">" },
    new { JsonKey = "resolution", ExpectedValue = "1080p", Operand = "=" }
};

var multiResults = searchLib.SearchMultipleJsonKeys(
    "VideoSourceConfigs",  // Table name
    "Basic_Params",        // Column name storing JSONB data
    conditions
);
