# OTSWhere
使阿里云表格存储 OTS 的条件过滤与数据格式化变得更简单
## Usage
```shell
$ npm i otswhere
```
### where 条件过滤
```js
const OTSWhere = require('otswhere');
const tbCondition = OTSWhere('(name=test&age>20)|age<18');
const params = {
tableName: 'test',
direction: TableStore.Direction.BACKWARD,
inclusiveStartPrimaryKey: [{ id: TableStore.INF_MAX }],
exclusiveEndPrimaryKey: [{ id: TableStore.IN_MIN }],
columnFilter: tbCondition // where condition
};
```
#### Operator
| operator | comment |
| --- | --- |
| = | TableStore.ComparatorType.EQUAL |
| != | TableStore.ComparatorType.NOT_EQUAL |
| > | TableStore.ComparatorType.GREATER_THAN |
| >= | TableStore.ComparatorType.GREATER_EQUAL |
| < | TableStore.ComparatorType.LESS_THAN |
| <= | TableStore.ComparatorType.LESS_EQUAL |
| & | TableStore.LogicalOperator.AND |
| \| | TableStore.LogicalOperator.OR |
### 数据格式化
将表格存储 getRange 与 getRow 返回的数据进行格式化，分别变为列表与对象：
```js
const format = require('otswhere/format');
// for getRow
const row = format.row({
primaryKey: [
{ name: 'name', value: 'test row'},
{ name: 'id', value: 123456 }
],
attributes: [
{ columnName: 'age', columnValue: 24 },
{ columnName: 'address', columnValue: 'HangZhou,China' },
]
});
console.log(row);
// {
// name: 'test row',
// id: 123456,
// age: 24,
// address: 'HangZhou,China'
// }
// for getRange
const rows = format.rows({
rows: [
{
primaryKey: [ { name: 'name', value: '1' }],
attributes: [ { columnName: 'age', columnValue: 24 }]
},
{
primaryKey: [ { name: 'name', value: '2' }],
attributes: [ { columnName: 'age', columnValue: 23 }]
}
],
next_start_primary_key: [
{ name: 'name', value: 3 }
]
});
console.log(rows);
// {
// list: [
// { name: '1', age: 24' },
// { name: '2', age: 23 },
// ],
// next: {
// name: 3
// }
// }
```
