On this page

The following mappings define how MySQL data types are represented in SingleStore.

String Types

MySQL Type	SingleStore Type
CHAR	CHAR
VARCHAR	VARCHAR
NCHAR	CHAR
NVARCHAR	VARCHAR
TEXT	TEXT
TINYTEXT	TINYTEXT
MEDIUMTEXT	MEDIUMTEXT
LONGTEXT	LONGTEXT
ENUM	ENUM

Integer Types

MySQL Type	SingleStore Type
TINYINT	TINYINT
SMALLINT	SMALLINT
MEDIUMINT	INT
INT / INTEGER	INT
BIGINT	BIGINT

Floating Point and Decimal Types

MySQL Type	SingleStore Type
FLOAT	FLOAT (if precision ≤ 24) DOUBLE (if precision > 24)
DOUBLE	DOUBLE
DOUBLE PRECISION	DOUBLE
DECIMAL	DECIMAL

Boolean Types

MySQL Type	SingleStore Type
BIT	BIT
BOOL / BOOLEAN	TINYINT

Binary Types

MySQL Type	SingleStore Type
BINARY	VARBINARY

Date and Time Types

MySQL Type	SingleStore Type
DATE	DATE
DATETIME	DATETIME
TIMESTAMP	DATETIME
TIME	TIME
YEAR	YEAR

Invalid MySQL Date and Time Values

Certain invalid DATETIME values are automatically converted to valid SingleStore values:

MySQL Type	SingleStore Type
0000-00-00 00:00:00	1000-01-01 00:00:00
0001-00-00 00:00:00	1001-01-01 00:00:00
0001-01-01 01:01:01	1001-01-01 01:01:01
0025-01-01 00:00:00	1025-01-01 00:00:00

For TIMESTAMP, the following conversion is applied:

MySQL Type	SingleStore Type
0000-00-00 00:00:00	1970-01-01 00:00:00

JSON

MySQL Type	SingleStore Type
JSON	JSON

Additional Notes

DATETIME is mapped to DATETIME if length = 19 (no fractional seconds) and DATETIME(6) if length > 19 (has fractional seconds).
FLOAT maps to FLOAT if precision ≤ 24, otherwise DOUBLE.

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 \
      --new-bundle-format -
