In numeric contexts it evaluates to its integer value (`0xFF` = `255`); otherwise it is treated as a binary string. This is a MySQL-specific form (distinct from the SQL-standard `x'1F'` hex-string literal) and is commonly used to express byte/hex constants.\n\n  See the MySQL docs:\n  https://dev.mysql.com/doc/refman/8.0/en/hexadecimal-literals.html\n\n  **SQL Example**\n\n  ```sql\n  CREATE TABLE t (\n    id INT PRIMARY KEY\n  );\n\n  INSERT INTO t (id) VALUES (1);\n\n  SELECT 0xFF FROM t;\n  ```\n  **Parsing error**\n\n`ParseException: Encountered: \u003cS_IDENTIFIER\u003e / \"t\", at line 1, column 18, in lexical state DEFAULT.`\n","author":{"url":"https://github.com/tomershay","@type":"Person","name":"tomershay"},"datePublished":"2026-06-14T20:17:21.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/2435/JSqlParser/issues/2435"}
