Data Type Mapping

On this page

SingleStore Kai natively supports the BSON data type for storage.

Note

The BSON type and BSON-specific functions must only be used for directly querying tables created by SingleStore Kai using SQL.

BSON Type Conversion

For all BLOB/string to BSON casting, SingleStore interprets the source as raw BSON bytes.
For JSON to BSON casting, SingleStore converts the JSON data according to the MongoDB® Extended JSON V2 format (Relaxed or Canonical).
BSON can be casted to JSON using the :>JSON notation. This conversion is performed in the MongoDB® Extended JSON V2 Relaxed format.

The following table maps SingleStore data types to the corresponding BSON data types :

SingleStore Data Type	BSON Data Type
BIGINT	INT64
BINARY	BINARY (subtype 0)
BIT	INT32 or INT64
BLOB	BINARY
CHAR	STRING
DATE	DATETIME
DATETIME	DATETIME
DATETIME(6)	DATETIME
DECIMAL	INT32, INT64, DOUBLE, or DECIMAL (based on size)
DOUBLE	DOUBLE
ENUM	STRING
FLOAT	DOUBLE
GEOGRAPHY	STRING
GEOGRAPHYPOINT	STRING
INT	INT32
JSON	BSON
LONGBLOB	BINARY
LONGTEXT	STRING
MEDIUMBLOB	BINARY
MEDIUMINT	INT32
MEDIUMTEXT	STRING
SMALLINT	INT32
TEXT	STRING
TIME	STRING
TIMESTAMP	DATETIME
TIMESTAMP6	DATETIME
TINYBLOB	BINARY
TINYINT	BOOLEAN
TINYTEXT	STRING
VARBINARY	BINARY
VARCHAR	STRING
YEAR	INT32

Verification instructions

Note: You must install cosign to verify the authenticity of the SingleStore file.

Use the following steps to verify the authenticity of singlestoredb-server, singlestoredb-toolbox, singlestoredb-studio, and singlestore-client SingleStore files that have been downloaded.

You may perform the following steps on any computer that can run cosign, such as the main deployment host of the cluster.

(Optional) Run the following command to view the associated signature files.
Shell
```
curl undefined
```
Download the signature file from the SingleStore release server.
- Option 1: Click the Download Signature button next to the SingleStore file.
- Option 2: Copy and paste the following URL into the address bar of your browser and save the signature file.
- Option 3: Run the following command to download the signature file.
  Shell
```
curl -O undefined
```

After the signature file has been downloaded, run the following command to verify the authenticity of the SingleStore file.

Shell

echo -n undefined |
    cosign verify-blob --certificate-oidc-issuer https://oidc.eks.us-east-1.amazonaws.com/id/CCDCDBA1379A5596AB5B2E46DCA385BC \
      --certificate-identity https://kubernetes.io/namespaces/freya-production/serviceaccounts/job-worker \
      --bundle undefined \
