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

For more information about SingleStore data types, refer to Data Types.

CHAR	CHAR
VARCHAR	VARCHAR
NCHAR	CHAR
NVARCHAR	VARCHAR
TEXT	TEXT
TINYTEXT	TINYTEXT
MEDIUMTEXT	MEDIUMTEXT
LONGTEXT	LONGTEXT

Integer Types

MySQL Type	SingleStore Type (more info)
TINYINT	TINYINT
SMALLINT	SMALLINT
MEDIUMINT	INT
INT / INTEGER	INT
BIGINT	BIGINT
BOOL / BOOLEAN	TINYINT

Floating Point and Decimal Types

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

Binary String Types

MySQL Type	SingleStore Type (more info)
BINARY	VARBINARY

Date and Time Types

MySQL Type	SingleStore Type (more info)
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 Types

MySQL Type	SingleStore Type (more info)
JSON	JSON

Other Types

MySQL Type	SingleStore Type (more info)
ENUM	ENUM

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 -
