# SQLHelper

A simplistic SQL generator extracted from [jdbc-helper](https://github.com/junegunn/jdbc-helper) gem.

This gem is not intended to be used independently outside the context of jdbc-helper.

## Example

```ruby

SQLHelper.select(

  prepared: true,

  table:    'mytable',

  project:  %w[a b c d e],

  where: [

    'z <> 100',

    ['y = ?', 200],

    {

      a: "hello 'world'",

      b: (1..10),

      c: (1...10),

      d: ['abc', "'def'"],

      e: { sql: 'sysdate' },

      f: { not: nil },

      g: { gt: 100 },

      h: { lt: 100 },

      i: { like: 'ABC%' },

      j: { not: { like: 'ABC%' } },

      k: { le: { sql: 'sysdate' } },

      l: { ge: 100, le: 200 },

      m: { not: [ 150, { ge: 100, le: 200 } ] },

      n: nil,

      o: { not: (1..10) },

      p: { or: [{ gt: 100 }, { lt: 50 }] },

      q: { like: ['ABC%', 'DEF%'] },

      r: { or: [{ like: ['ABC%', 'DEF%'] }, { not: { like: 'XYZ%' } }] }

    }

  ],

  order: 'a desc',

  limit: 10

)

```
