Support new 8.0 functions

[derekperkins]

JSON

• JSON_TABLE(expr, path COLUMNS column_list) [AS] alias)
• Added the ->> (inline path) operator, which is equivalent to calling JSON_UNQUOTE() on the result of JSON_EXTRACT()
• JSON_ARRAYAGG(col_or_expr)
• JSON_OBJECTAGG(key, value)
• JSON_PRETTY(json_val)
• JSON_STORAGE_SIZE(json_val)
• JSON_STORAGE_FREE(json_val)
• JSON_MERGE_PATCH(json_doc, json_doc[, json_doc] ...)
• JSON_MERGE() function has been renamed JSON_MERGE_PRESERVE(). JSON_MERGE() continues to be recognized as an alias for JSON_MERGE_PRESERVE()
• Added support in MySQL 8.0.2 for ranges such as $[1 to 5] in XPath expressions. Also added support in this version for the last keyword and relative addressing, such that $[last] always selects the last (highest-numbered) element in the array and $[last-1] the next to last element. last and expressions using it can also be included in range definitions; for example, $[last-2 to last-1] returns the last two elements but one from an array.

Window

• CUME_DIST() over_clause
• DENSE_RANK() over_clause
• FIRST_VALUE(expr) [null_treatment] over_clause
• LAG(expr [, N[, default]]) [null_treatment] over_clause
• LAST_VALUE(expr) [null_treatment] over_clause
• LEAD(expr [, N[, default]]) [null_treatment] over_clause
• NTH_VALUE(expr, N) [from_first_last] [null_treatment] over_clause
• NTILE(N) over_clause
• PERCENT_RANK() over_clause
• RANK() over_clause
• ROW_NUMBER() over_clause

Regular Expressions

• REGEXP_INSTR(expr, pat[, pos[, occurrence[, return_option[, match_type]]]])
• REGEXP_LIKE(expr, pat[, match_type])
• REGEXP_REPLACE(expr, pat, repl[, pos[, occurrence[, match_type]]])
• REGEXP_SUBSTR(expr, pat[, pos[, occurrence[, match_type]]])

WITH Syntax (Common Table Expressions)

• This feels like a bigger change rather than just adding function parsing support https://dev.mysql.com/doc/refman/8.0/en/with.html
