MAINTAINER:
1) Comments for TOKENS.
For each token, please include in the same line a comment that contains
one or more of the following tags:
SQL-2015-N : Non Reserved keyword as per SQL-2015 draft
SQL-2015-R : Reserved keyword as per SQL-2015 draft
SQL-2003-R : Reserved keyword as per SQL-2003
SQL-2003-N : Non Reserved keyword as per SQL-2003
SQL-1999-R : Reserved keyword as per SQL-1999
SQL-1999-N : Non Reserved keyword as per SQL-1999
MYSQL : MySQL extension (unspecified)
MYSQL-FUNC : MySQL extension, function
INTERNAL : Not a real token, lex optimization
OPERATOR : SQL operator
FUTURE-USE : Reserved for futur use
This makes the code grep-able, and helps maintenance.
2) About token values
Token values are assigned by bison, in order of declaration.
Token values are used in query DIGESTS.
To make DIGESTS stable, it is desirable to avoid changing token values.
In practice, this means adding new tokens at the end of the list,
in the current release section (8.0),
instead of adding them in the middle of the list.
Failing to comply with instructions below will trigger build failure,
as this process is enforced by gen_lex_token.
3) Instructions to add a new token:
Add the new token at the end of the list,
in the MySQL 8.0 section.
4) Instructions to remove an old token:
Do not remove the token, rename it as follows:
%token OBSOLETE_TOKEN_<NNN> / * was: TOKEN_FOO * /
where NNN is the token value (found in sql_yacc.h)
For example, see OBSOLETE_TOKEN_820

/*
MySQL has a syntax extension that allows into clauses in any one of two
places. They may appear either before the from clause or at the end. All in
a top-level select statement. This extends the standard syntax in two
ways. First, we don't have the restriction that the result can contain only
one row: the into clause might be INTO OUTFILE/DUMPFILE in which case any
number of rows is allowed. Hence MySQL does not have any special case for
the standard's <select statement: single row>. Secondly, and this has more
severe implications for the parser, it makes the grammar ambiguous, because
in a from-clause-less select statement with an into clause, it is not clear
whether the into clause is the leading or the trailing one.
While it's possible to write an unambiguous grammar, it would force us to
duplicate the entire <select statement> syntax all the way down to the <into
clause>. So instead we solve it by writing an ambiguous grammar and use
precedence rules to sort out the shift/reduce conflict.
The problem is when the parser has seen SELECT <select list>, and sees an
INTO token. It can now either shift it or reduce what it has to a table-less
query expression. If it shifts the token, it will accept seeing a FROM token
next and hence the INTO will be interpreted as the leading INTO. If it
reduces what it has seen to a table-less select, however, it will interpret
INTO as the trailing into. But what if the next token is FROM? Obviously,
we want to always shift INTO. We do this by two precedence declarations: We
make the INTO token right-associative, and we give it higher precedence than
an empty from clause, using the artificial token EMPTY_FROM_CLAUSE.
The remaining problem is that now we allow the leading INTO anywhere, when
it should be allowed on the top level only. We solve this by manually
throwing parse errors whenever we reduce a nested query expression if it
contains an into clause.

/**
A <query_expression> within parentheses can be used as an <expr>. Now,
because both a <query_expression> and an <expr> can appear syntactically
within any number of parentheses, we get an ambiguous grammar: Where do the
parentheses belong? Techically, we have to tell Bison by which rule to
reduce the extra pair of parentheses. We solve it in a somewhat tedious way
by defining a query_expression so that it can't have enclosing
parentheses. This forces us to be very explicit about exactly where we allow
parentheses; while the standard defines only one rule for <query expression>
parentheses, we have to do it in several places. But this is a blessing in
disguise, as we are able to define our syntax in a more fine-grained manner,
and this is necessary in order to support some MySQL extensions, for example
as in the last two sub-rules here.
Even if we define a query_expression not to have outer parentheses, we still
get a shift/reduce conflict for the <subquery> rule, but we solve this by
using an artifical token SUBQUERY_AS_EXPR that has less priority than
parentheses. This ensures that the parser consumes as many parentheses as it
can, and only when that fails will it try to reduce, and by then it will be
clear from the lookahead token whether we have a subquery or just a
query_expression within parentheses. For example, if the lookahead token is
UNION it's just a query_expression within parentheses and the parentheses
don't mean it's a subquery. If the next token is PLUS, we know it must be an
<expr> and the parentheses really mean it's a subquery.
A word about CTE's: The rules below are duplicated, one with a with_clause
and one without, instead of using a single rule with an opt_with_clause. The
reason we do this is because it would make Bison try to cram both rules into
a single state, where it would have to decide whether to reduce a with_clause
before seeing the rest of the input. This way we force Bison to parse the
entire query expression before trying to reduce.

Join operations are normally left-associative, as in
t1 JOIN t2 ON t1.a = t2.a JOIN t3 ON t3.a = t2.a
This is equivalent to
(t1 JOIN t2 ON t1.a = t2.a) JOIN t3 ON t3.a = t2.a
They can also be right-associative without parentheses, e.g.
t1 JOIN t2 JOIN t3 ON t2.a = t3.a ON t1.a = t2.a
Which is equivalent to
t1 JOIN (t2 JOIN t3 ON t2.a = t3.a) ON t1.a = t2.a
In MySQL, JOIN and CROSS JOIN mean the same thing, i.e.:
- A join without a <join specification> is the same as a cross join.
- A cross join with a <join specification> is the same as an inner join.
For the join operation above, this means that the parser can't know until it
has seen the last ON whether `t1 JOIN t2` was a cross join or not. The only
way to solve the abiguity is to keep shifting the tokens on the stack, and
not reduce until the last ON is seen. We tell Bison this by adding a fake
token CONDITIONLESS_JOIN which has lower precedence than all tokens that
would continue the join. These are JOIN_SYM, INNER_SYM, CROSS,
STRAIGHT_JOIN, NATURAL, LEFT, RIGHT, ON and USING. This way the automaton
only reduces to a cross join unless no other interpretation is
possible. This gives a right-deep join tree for join *with* conditions,
which is what is expected.
The challenge here is that t1 JOIN t2 *could* have been a cross join, we
just don't know it until afterwards. So if the query had been
t1 JOIN t2 JOIN t3 ON t2.a = t3.a
we will first reduce `t2 JOIN t3 ON t2.a = t3.a` to a <table_reference>,
which is correct, but a problem arises when reducing t1 JOIN
<table_reference>. If we were to do that, we'd get a right-deep tree. The
solution is to build the tree downwards instead of upwards, as is normally
done. This concept may seem outlandish at first, but it's really quite
simple. When the semantic action for table_reference JOIN table_reference is
executed, the parse tree is (please pardon the ASCII graphic):
JOIN ON t2.a = t3.a
/ \
t2 t3
Now, normally we'd just add the cross join node on top of this tree, as:
JOIN
/ \
t1 JOIN ON t2.a = t3.a
/ \
t2 t3
This is not the meaning of the query, however. The cross join should be
addded at the bottom:
JOIN ON t2.a = t3.a
/ \
JOIN t3
/ \
t1 t2
There is only one rule to pay attention to: If the right-hand side of a
cross join is a join tree, find its left-most leaf (which is a table
name). Then replace this table name with a cross join of the left-hand side
of the top cross join, and the right hand side with the original table.
Natural joins are also syntactically conditionless, but we need to make sure
that they are never right associative. We handle them in their own rule
natural_join, which is left-associative only. In this case we know that
there is no join condition to wait for, so we can reduce immediately.

/**
MySQL has a syntax extension where a comma-separated list of table
references is allowed as a table reference in itself, for instance
SELECT * FROM (t1, t2) JOIN t3 ON 1
which is not allowed in standard SQL. The syntax is equivalent to
SELECT * FROM (t1 CROSS JOIN t2) JOIN t3 ON 1
We call this rule table_reference_list_parens.
A <table_factor> may be a <single_table>, a <subquery>, a <derived_table>, a
<joined_table>, or the bespoke <table_reference_list_parens>, each of those
enclosed in any number of parentheses. This makes for an ambiguous grammar
since a <table_factor> may also be enclosed in parentheses. We get around
this by designing the grammar so that a <table_factor> does not have
parentheses, but all the sub-cases of it have their own parentheses-rules,
i.e. <single_table_parens>, <joined_table_parens> and
<table_reference_list_parens>. It's a bit tedious but the grammar is
unambiguous and doesn't have shift/reduce conflicts.

This warning will be printed when
[1] A client query is parsed,
[2] A stored function is loaded by db_load_routine.
Printing the warning for [2] is intentional, to cover the
following scenario:
- A user define a SF 'foo' using MySQL 5.N
- An application uses select foo(), and works.
- MySQL 5.{N+1} defines a new native function 'foo', as
part of a new feature.
- MySQL 5.{N+1} documentation is updated, and should mention
that there is a potential incompatible change in case of
existing stored function named 'foo'.
- The user deploys 5.{N+1}. At this point, 'select foo()'
means something different, and the user code is most likely
broken (it's only safe if the code is 'select db.foo()').
With a warning printed when the SF is loaded (which has to occur
before the call), the warning will provide a hint explaining
the root cause of a later failure of 'select foo()'.
With no warning printed, the user code will fail with no
apparent reason.
Printing a warning each time db_load_routine is executed for
an ambiguous function is annoying, since that can happen a lot,
but in practice should not happen unless there *are* name
collisions.
If a collision exists, it should not be silenced but fixed.
