Reserved Words in Java Here's the full list of words you cannot use in Java. Manually we are putting them in double quotes to run. PostgreSQL functions, also known as Stored Procedures, allow you to carry out operations that would normally take several queries and round trips in a single function within the database.Functions allow database reuse as other applications can interact directly with your stored procedures instead of a middle-tier or duplicating code. C-1 lists all tokens that are key words in the SQL standard i.e. functions or data types with special syntax. the standard, reserved key words are the only real key words; I am not entirely sure about your objective, but what you show works with legal identifiers. Essentially, I have a separate from which I can get word details and would like to join an unnested array of that string on this dictionary. label names (and perhaps in very few other contexts).
