Important

The SingleStore 9.0 release candidate (RC) gives you the opportunity to preview, evaluate, and provide feedback on new and upcoming features prior to their general availability. In the interim, SingleStore 8.9 is recommended for production workloads, which can later be upgraded to SingleStore 9.0.

BSON_INPUT_STREAM_TO_ARRAY

Syntax

BSON_INPUT_STREAM_TO_ARRAY(<input>)

Arguments

input: A valid BSON array, an expression that evaluates to a valid BSON array, or concatenated BSON documents.

Return Type

A PSQL array.

Examples

Note: The following examples explicitly cast string to BSON for clarity. Similarly, the output is cast to JSON.

Convert a BSON array:

SQL

SELECT table_col:>JSON AS Result 
FROM TABLE(BSON_INPUT_STREAM_TO_ARRAY('[{"a":1},{"b":2},{"c":3},{"d":4}]':>BSON));

+---------+
| Result  |
+---------+
| {"a":1} |
| {"b":2} |
| {"c":3} |
| {"d":4} |
+---------+

SQL

SELECT table_col:>JSON AS Result 
FROM TABLE(BSON_INPUT_STREAM_TO_ARRAY('[{"a":1,"b":"abcdef","c":null},{"b":2,"e":{"f":{"g":[]}}},{"c":3},{}]':>JSON:>BSON));

+-------------------------------+
| Result                        |
+-------------------------------+
| {"a":1,"b":"abcdef","c":null} |
| {"b":2,"e":{"f":{"g":[]}}}    |
| {"c":3}                       |
| {}                            |
+-------------------------------+

Convert concatenated documents:

SQL

SELECT table_col:>JSON AS Result 
FROM TABLE(BSON_INPUT_STREAM_TO_ARRAY(x'0C00000010610001000000000C00000010620002000000000C00000010630003000000000C0000001064000400000000')) 
AS Result;

+---------+
| Result  |
+---------+
| {"a":1} |
| {"b":2} |
| {"c":3} |
| {"d":4} |
+---------+

where, x'0C00000010610001000000000C00000010620002000000000C00000010630003000000000C0000001064000400000000' is a hex literal that is formed by concatenating the following BSON documents:

Document	Hex Representation
`{"a":1}`	`0C0000001061000100000000`
`{"b":2}`	`0C0000001062000200000000`
`{"c":3}`	`0C0000001063000300000000`
`{"d":4}`	`0C0000001064000400000000`
