Description

When exporting trigger statements that contain subtraction without spaces between values, mysqldef fails with a syntax error.

SQL

    CREATE TABLE test_trigger (
      id int(11) NOT NULL AUTO_INCREMENT,
      `status` int(4),
      PRIMARY KEY (id)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
    CREATE TRIGGER `test_trigger_BEFORE_INSERT` before insert ON `test_trigger` FOR EACH ROW begin
    set NEW.status = 1+1-1;
    end;

Error

found syntax error when parsing DDL "CREATE TRIGGER `test_trigger_BEFORE_INSERT` before insert ON `test_trigger` FOR EACH ROW begin
        set NEW.status = 1+1-1;
        end": syntax error at position 118 near '-1'

Additional information

• When there are spaces around the - operator (e.g., 1 + 1 - 1), it works without errors
• The syntax error only occurs when there are no spaces (e.g., 1+1-1)
• The SQL itself is valid MySQL syntax, so mysqldef should be able to parse it correctly
