 # knex-json-query
 A high-level utility which will will generate Knex query from a single JSON object.
+
+it is a simple function with just ~80 lines of code.
+
+## Usage
+
+```javascript
+var knex = require('knex');
+//var KnexJsonQuery = require('knex-json-query');
+var KnexJsonQuery = require('./');
+var jsonInput = {f1:{ $like: 'test%' }, $and: [{f2:22, f3: 33}] };
+var queryBuilderFunction = KnexJsonQuery( jsonInput );
+
+var sql = knex.where( queryBuilderFunction ).toString()
+console.log( sql );
+
+```
+
+**Output**
+```
+select * where ("f1" LIKE 'test%' and (("f2" = 22 and "f3" = 33)))
+```
+
+## Examples
+
+For more details, see the [test.js](./test.js)
+
+**Examples from Unit test file:**
+
+1. simple and conditions
+    - *input JSON*: `{"f1":10,"f2":20,"f3":30}`
+    - *output SQL*: `select * where ("f1" = 10 and "f2" = 20 and "f3" = 30)`
+
+2. simple and conditions
+    - *input JSON*: `{"firstName":[["LIKE","H%"],["OR","hemanth"]]}`
+    - *output SQL*: `select * where (("firstName" LIKE 'H%' or "firstName" = 'hemanth'))`
+
+3. regex query: MongoQuery
+    - *input JSON*: `{"firstName":{"$regex":"H*"}}`
+    - *output SQL*: `select * where ("firstName" REGEXP 'H*')`
+
+4. regex query and should omit $options: MongoQuery
+    - *input JSON*: `{"firstName":{"$regex":"H*","$options":"i"}}`
+    - *output SQL*: `select * where ("firstName" REGEXP 'H*')`
+
+5. simple and conditions
+    - *input JSON*: `{"f1":[["A"],["LIKE","B"]],"f2":20,"f3":30}`
+    - *output SQL*: `select * where (("f1" = 'A' and "f1" LIKE 'B') and "f2" = 20 and "f3" = 30)`
+
+6. basic operators :: greater-than less-than
+    - *input JSON*: `{"f1":[">",10],"f2":["<",20],"f3":30}`

+
+7. basic operators :: in
+    - *input JSON*: `{"f1":["IN",[10,50]],"f2":["<",20],"f3":30}`

+
+8. basic operators :: notin
+    - *input JSON*: `{"f1":["NOTIN",[10,50]],"f2":["<",20],"f3":30}`

+9. multiple conditions in one field
+    - *input JSON*: `{"f1":[["LIKE",20],21,["AND_BETWEEN",[40,45]]],"f2":20,"f3":30}`
