SQLSTATE: 42601

Support of the clause or keyword: <clause> has been discontinued in this context.

This error class has the following derived error classes:

BANG_EQUALS_NOT

The ‘!’ keyword is supported as a prefix operator in a logical operation only. Use the ‘NOT’ keyword instead for clauses such as NOT LIKE, NOT IN, NOT BETWEEN, etc. To re-enable the ‘!’ keyword, set “spark.sql.legacy.bangEqualsNot” to “true”.
