* @package BaoPham\DynamoDb\DynamoDb |

|
|
|
* Methods are in the form of `set<key_name>`, where `<key_name>` |

17

* is the key name of the query body to be sent. |
|
18
|
|
|
* |
|
19
|
|
|
* For example, to build a query: |
|
20
|
|
|
* [ |
|
21
|
|
|
* 'AttributeDefinitions' => ..., |
|
22
|
|
|

|
23
|
|
|
* 'TableName' => ... |
|
24
|
|
|
* ] |
|
25
|
|
|
* |
|
26
|
|
|
* Do: |
|
27
|
|
|
* |
|
28
|
|
|
* $query = $query->setAttributeDefinitions(...)->setGlobalSecondaryIndexUpdates(...)->setTableName(...); |
|
29
|
|
|
* |
|
30
|
|
|
* When ready: |
|
31
|
|
|
* |
|
32
|
|
|
* $query->prepare()->updateTable(); |
