Validate MAC Address Format in PostgreSQL with Regex

Use PostgreSQL regex to validate MAC address format in network device tables. SQL examples for MAC address validation.

The Regex Pattern

Regex pattern

^([0-9A-Fa-f]{2}[:-]){5}([0-9A-Fa-f]{2})$

Use this pattern with PostgreSQL's ~ operator.

PostgreSQL SQL Example

-- Validate MAC address format in a PostgreSQL network_devices or access_logs table using regex ~ operator
SELECT *
FROM your_table
WHERE your_column ~ '^([0-9A-Fa-f]{2}[:-]){5}([0-9A-Fa-f]{2})$';

How This Works

Validate MAC address format in a PostgreSQL network_devices or access_logs table using regex ~ operator. The regex pattern is used with PostgreSQL's ~ operator to filter rows at the database level.

Using regex directly in SQL is efficient for use cases like data validation — it avoids loading data into application memory just to filter it with a regex.
