18 : * Andrew Yu Sept, 1994 POSTQUEL to SQL conversion

20 : *
21 : * NOTES
22 : * CAPITALS are used to represent terminal symbols.
23 : * non-capitals are used to represent non-terminals.
24 : *
25 : * In general, nothing in this file should initiate database accesses
26 : * nor depend on changeable state (such as SET variables). If you do
27 : * database accesses, your code will fail when we have aborted the
28 : * current transaction and are just parsing commands to find the next
29 : * ROLLBACK or COMMIT. If you make use of SET variables, then you
30 : * will do the wrong thing in multi-query strings like this:
31 : * SET constraint_exclusion TO off; SELECT * FROM foo;
32 : * because the entire string is parsed by gram.y before the SET gets
33 : * executed. Anything that depends on the database or changeable state
34 : * should be handled during parse analysis so that it happens at the
35 : * right time not the wrong time.
36 : *
37 : * WARNINGS
38 : * If you use a list, make sure the datum is a node so that the printing
39 : * routines work.
40 : *
41 : * Sometimes we assign constants to makeStrings. Make sure we don't free
42 : * those.

849 : * assignments have global effect and may hide ambiguities besides the one

851 : * %prec is far safer and should be preferred.) If you must give precedence
852 : * to a new keyword, try very hard to give it the same precedence as IDENT.
853 : * If the keyword has IDENT's precedence then it clearly acts the same as
854 : * non-keywords and other similar keywords, thus reducing the risk of
855 : * unexpected precedence effects.
856 : *
857 : * We used to need to assign IDENT an explicit precedence just less than Op,
858 : * to support target_el without AS. While that's not really necessary since
859 : * we removed postfix operators, we continue to do so because it provides a
860 : * reference point for a precedence level that we can assign to other
861 : * keywords that lack a natural precedence level.
862 : *
863 : * We need to do this for PARTITION, RANGE, ROWS, and GROUPS to support
864 : * opt_existing_window_name (see comment there).

867 : * are even messier: since UNBOUNDED is an unreserved keyword (per spec!),
868 : * there is no principled way to distinguish these from the productions
869 : * a_expr PRECEDING/FOLLOWING. We hack this up by giving UNBOUNDED slightly
870 : * lower precedence than PRECEDING and FOLLOWING. At present this doesn't
871 : * appear to cause UNBOUNDED to be treated differently from other unreserved
872 : * keywords anywhere else in the grammar, but it's definitely risky. We can
873 : * blame any funny behavior of UNBOUNDED on the SQL standard, though.
874 : *
875 : * To support CUBE and ROLLUP in GROUP BY without reserving them, we give them
876 : * an explicit priority lower than '(', so that a rule with CUBE '(' will shift
877 : * rather than reducing a conflicting rule that takes CUBE as a function name.
878 : * Using the same precedence as IDENT seems right for the reasons given above.
879 : *
880 : * SET is likewise assigned the same precedence as IDENT, to support the
881 : * relation_expr_opt_alias production (see comment there).
882 : *
883 : * KEYS, OBJECT_P, SCALAR, VALUE_P, WITH, and WITHOUT are similarly assigned
884 : * the same precedence as IDENT. This allows resolving conflicts in the

886 : * productions (see comments there).

12956 : /* A complete SELECT statement looks like this.
12957 : *
12958 : * The rule returns either a single SelectStmt node or a tree of them,
12959 : * representing a set-operation tree.
12960 : *
12961 : * There is an ambiguity when a sub-SELECT is within an a_expr and there
12962 : * are excess parentheses: do the parentheses belong to the sub-SELECT or
12963 : * to the surrounding a_expr? We don't really care, but bison wants to know.
12964 : * To resolve the ambiguity, we are careful to define the grammar so that
12965 : * the decision is staved off as long as possible: as long as we can keep
12966 : * absorbing parentheses into the sub-SELECT, we will do so, and only when
12967 : * it's no longer possible to do that will we decide that parens belong to
12968 : * the expression. For example, in "SELECT (((SELECT 2)) + 3)" the extra
12969 : * parentheses are treated as part of the sub-select. The necessity of doing
12970 : * it that way is shown by "SELECT (((SELECT 2)) UNION SELECT 2)". Had we
12971 : * parsed "((SELECT 2))" as an a_expr, it'd be too late to go back to the
12972 : * SELECT viewpoint when we see the UNION.
12973 : *
12974 : * This approach is implemented by defining a nonterminal select_with_parens,
12975 : * which represents a SELECT with at least one outer layer of parentheses,
12976 : * and being careful to use select_with_parens, never '(' SelectStmt ')',
12977 : * in the expression grammar. We will then have shift-reduce conflicts
12978 : * which we can resolve in favor of always treating '(' <select> ')' as
12979 : * a select_with_parens. To resolve the conflicts, the productions that
12980 : * conflict with the select_with_parens productions are manually given
12981 : * precedences lower than the precedence of ')', thereby ensuring that we
12982 : * shift ')' (and then reduce to select_with_parens) rather than trying to
12983 : * reduce the inner <select> nonterminal to something else. We use UMINUS
12984 : * precedence for this, which is a fairly arbitrary choice.
12985 : *
12986 : * To be able to define select_with_parens itself without ambiguity, we need
12987 : * a nonterminal select_no_parens that represents a SELECT structure with no
12988 : * outermost parentheses. This is a little bit tedious, but it works.
12989 : *
12990 : * In non-expression contexts, we use SelectStmt which can represent a SELECT
12991 : * with or without outer parentheses.
