Retrieves records from a collection. The operation can optionally return the record IDs which can be used in certain queries such as Delete Records.
This operation supports paging through the data via the input parameter offset and input parameter limit parameters.
Note that when using the Java API, it is not possible to retrieve records from join tables using this operation.

Output Parameter Description
Name | Type | Description |
---|---|---|
table_name | string | Value of input parameter table_name. |
type_names | array of strings | The type IDs of the corresponding records in output parameter records_binary or output parameter records_json. This is useful when input parameter table_name is a heterogeneous collection (collections containing tables of different types). |
records_binary | array of bytes | If the encoding parameter of the request was 'binary' then this list contains the binary encoded records retrieved from the table/collection. Otherwise, empty list. |
records_json | array of strings | If the encoding parameter of the request was 'json', then this list contains the JSON encoded records retrieved from the table/collection. Otherwise, empty list. |
record_ids | array of strings | If the 'return_record_ids' option of the request was 'true', then this list contains the internal ID for each object. Otherwise it will be empty. |
