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.

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

843 : * If the keyword has IDENT's precedence then it clearly acts the same as
844 : * non-keywords and other similar keywords, thus reducing the risk of
845 : * unexpected precedence effects.
846 : *
847 : * We used to need to assign IDENT an explicit precedence just less than Op,

852 : *
853 : * We need to do this for PARTITION, RANGE, ROWS, and GROUPS to support
854 : * opt_existing_window_name (see comment there).

857 : * are even messier: since UNBOUNDED is an unreserved keyword (per spec!),
858 : * there is no principled way to distinguish these from the productions
859 : * a_expr PRECEDING/FOLLOWING. We hack this up by giving UNBOUNDED slightly
860 : * lower precedence than PRECEDING and FOLLOWING. At present this doesn't
861 : * appear to cause UNBOUNDED to be treated differently from other unreserved
862 : * keywords anywhere else in the grammar, but it's definitely risky. We can
863 : * blame any funny behavior of UNBOUNDED on the SQL standard, though.
864 : *
865 : * To support CUBE and ROLLUP in GROUP BY without reserving them, we give them
866 : * an explicit priority lower than '(', so that a rule with CUBE '(' will shift
867 : * rather than reducing a conflicting rule that takes CUBE as a function name.
868 : * Using the same precedence as IDENT seems right for the reasons given above.
869 : *
870 : * SET is likewise assigned the same precedence as IDENT, to support the
871 : * relation_expr_opt_alias production (see comment there).
872 : *
873 : * KEYS, OBJECT_P, SCALAR, VALUE_P, WITH, and WITHOUT are similarly assigned

12834 : * The rule returns either a single SelectStmt node or a tree of them,

12836 : *
12837 : * There is an ambiguity when a sub-SELECT is within an a_expr and there
12838 : * are excess parentheses: do the parentheses belong to the sub-SELECT or
12839 : * to the surrounding a_expr? We don't really care, but bison wants to know.
12840 : * To resolve the ambiguity, we are careful to define the grammar so that
12841 : * the decision is staved off as long as possible: as long as we can keep
12842 : * absorbing parentheses into the sub-SELECT, we will do so, and only when
12843 : * it's no longer possible to do that will we decide that parens belong to
12844 : * the expression. For example, in "SELECT (((SELECT 2)) + 3)" the extra
12845 : * parentheses are treated as part of the sub-select. The necessity of doing
12846 : * it that way is shown by "SELECT (((SELECT 2)) UNION SELECT 2)". Had we
12847 : * parsed "((SELECT 2))" as an a_expr, it'd be too late to go back to the
12848 : * SELECT viewpoint when we see the UNION.
12849 : *
12850 : * This approach is implemented by defining a nonterminal select_with_parens,
12851 : * which represents a SELECT with at least one outer layer of parentheses,
12852 : * and being careful to use select_with_parens, never '(' SelectStmt ')',
12853 : * in the expression grammar. We will then have shift-reduce conflicts
12854 : * which we can resolve in favor of always treating '(' <select> ')' as
12855 : * a select_with_parens. To resolve the conflicts, the productions that
12856 : * conflict with the select_with_parens productions are manually given
12857 : * precedences lower than the precedence of ')', thereby ensuring that we
12858 : * shift ')' (and then reduce to select_with_parens) rather than trying to
12859 : * reduce the inner <select> nonterminal to something else. We use UMINUS
12860 : * precedence for this, which is a fairly arbitrary choice.
12861 : *
12862 : * To be able to define select_with_parens itself without ambiguity, we need
12863 : * a nonterminal select_no_parens that represents a SELECT structure with no
12864 : * outermost parentheses. This is a little bit tedious, but it works.
12865 : *
12866 : * In non-expression contexts, we use SelectStmt which can represent a SELECT
12867 : * with or without outer parentheses.

12959 : *
12960 : * As with select_no_parens, simple_select cannot have outer parentheses,

12962 : *
12963 : * It might appear that we could fold the first two alternatives into one

12965 : * against INSERT ... SELECT ... ON CONFLICT. We avoid the ambiguity by
12966 : * requiring SELECT DISTINCT [ON] to be followed by a non-empty target_list.
12967 : *
12968 : * Note that sort clauses cannot be included at this level --- SQL requires
12969 : * SELECT foo UNION SELECT bar ORDER BY baz
12970 : * to be parsed as
12971 : * (SELECT foo UNION SELECT bar) ORDER BY baz
12972 : * not
12973 : * SELECT foo UNION (SELECT bar ORDER BY baz)
12974 : * Likewise for WITH, FOR UPDATE and LIMIT. Therefore, those clauses are
12975 : * described as part of the select_no_parens production, not simple_select.
12976 : * This does not limit functionality, because you can reintroduce these
12977 : * clauses inside parentheses.
12978 : *
12979 : * NOTE: only the leftmost component SelectStmt should have INTO.
12980 : * However, this is not checked by the grammar; parse analysis must check it.

14974 : * We have two expression types: a_expr is the unrestricted kind, and
14975 : * b_expr is a subset that must be used in some places to avoid shift/reduce
14976 : * conflicts. For example, we can't do BETWEEN as "BETWEEN a_expr AND a_expr"
14977 : * because that use of AND conflicts with AND as a boolean operator. So,
14978 : * b_expr is used in BETWEEN and we remove boolean keywords from b_expr.
14979 : *
14980 : * Note that '(' a_expr ')' is a b_expr, so an unrestricted expression can
14981 : * always be used by surrounding it with parens.
14982 : *
14983 : * c_expr is all the productions that are common to a_expr and b_expr;
14984 : * it's factored out just to eliminate redundant coding.
14985 : *
14986 : * Be careful of productions involving more than one terminal token.
14987 : * By default, bison will assign such productions the precedence of their
14988 : * last terminal, but in nearly all cases you want it to be the precedence
14989 : * of the first terminal instead; otherwise you will not get the behavior
14990 : * you expect! So we use %prec annotations freely to set precedences.
