mindsdb_sql_parser/parser.py (1)

1758-1761: ON is parsed as a string constant ('ON') instead of a boolean True, which can cause incorrect runtime behavior for SQL like SET @@var=ON.

📊 Impact Scores:

• Production Impact: 4/5
• Fix Specificity: 5/5
• Urgency Impact: 3/5
• Total Score: 12/15

🤖 AI Agent Prompt (Copy & Paste Ready):

In mindsdb_sql_parser/parser.py, lines 1758-1761, the parser currently returns `Constant(value='ON', with_quotes=False)` for the `ON` keyword. This causes `ON` to be treated as a string instead of a boolean, which is incorrect for SQL statements like `SET @@var=ON`. Change the return value to `Constant(value=True)` so that `ON` is parsed as a boolean True.
