## Recipes

* [Add resultset limit](http://g14n.info/SQL92-JSON/recipes/resultset-limit/) (WiP)

* [Compute resultset count](http://g14n.info/SQL92-JSON/recipes/resultset-count/)

* [Prepend pool header](http://g14n.info/SQL92-JSON/recipes/spool-header/)

* [Table list](http://g14n.info/SQL92-JSON/recipes/table-list/) (PoC)

## Examples

See [examples] folder where every `.json` file has its homonym `.sql`.

See for example the following [example JSON][exampleJSON] and its [corresponding SQL][exampleSQL].

```json

{

  "SELECT": [ { "COUNT": "*", "AS": "num" } ],

  "FROM": [

    {

      "SELECT": ["*"],

      "FROM": ["mytable"],

      "WHERE": [

        "yyyymmdd", { "=": 20170101 },

        { "AND": [ "country", { "IN": ["IT", "US"] } ] },

        { "AND": [

          "categoryid", { "BETWEEN": [100, 200] },

          { "OR": [ "productname", { "!=": "'icecream'" } ] }

        ] }

      ]

    }

  ]

}

```

```sql

SELECT COUNT(*) AS num

FROM (

	SELECT *

	FROM mytable

	WHERE yyyymmdd = 20170101

		AND country IN ( 'IT', 'US' )

		AND (

			categoryid BETWEEN 100 AND 200

			OR productname != 'icecream'

		)

)

```
