+
+ This function is invoked by the bison-generated parser
+ when a syntax error, a parse error or an out-of-memory
+ condition occurs. This function is not invoked when the
+ parser is requested to abort by semantic action code
+ by means of YYABORT or YYACCEPT macros. This is why these
+ macros should not be used (use MYSQL_YYABORT/MYSQL_YYACCEPT
+ instead).
+
+ The parser will abort immediately after invoking this callback.
+
+ This function is not for use in semantic actions and is internal to
+ the parser, as it performs some pre-return cleanup.
+ In semantic actions, please use thd->parse_error() or my_error to
+ push an error into the error stack and MYSQL_YYABORT
+ to abort from the parser.

+ Tokens that can change their meaning from identifier to something else
+ in certain context.
+
+ - TRANSACTION: identifier, history unit:
+ SELECT transaction FROM t1;
+ SELECT * FROM t1 FOR SYSTEM_TIME AS OF TRANSACTION @var;
+
+ - TIMESTAMP: identifier, literal, history unit:
+ SELECT timestamp FROM t1;
+ SELECT TIMESTAMP '2001-01-01 10:20:30';
+ SELECT * FROM t1 FOR SYSTEM_TIME AS OF TIMESTAMP CONCAT(@date,' ',@time);
+
+ - PERIOD: identifier, period for system time:
+ SELECT period FROM t1;
+ ALTER TABLE DROP PERIOD FOR SYSTEM TIME;
+
+ - SYSTEM: identifier, system versioning:
+ SELECT system FROM t1;
+ ALTER TABLE DROP SYSTEM VERSIONIONG;
+
+ - USER: identifier, user:
+ SELECT user FROM t1;
+ KILL USER foo;
+
+ Note, we need here only tokens that cause shift/reduce conflicts
+ with keyword identifiers. For example:
+ opt_clause1: %empty | KEYWORD ... ;
+ clause2: opt_clause1 ident;
+ KEYWORD can appear both in opt_clause1 and in "ident" through the "keyword"
+ rule. So the parser reports a conflict on how to interpret KEYWORD:
+ - as a start of non-empty branch in opt_clause1, or
+ - as an identifier which follows the empty branch in opt_clause1.
+
+ Example#1:
+ alter_list_item:
+ DROP opt_column opt_if_exists_table_element field_ident
+ | DROP SYSTEM VERSIONING_SYM
+ SYSTEM can be a keyword in field_ident, or can be a start of
+ SYSTEM VERSIONING.
+
+ Example#2:
+ system_time_expr: AS OF_SYM history_point
+ history_point: opt_history_unit bit_expr
+ opt_history_unit: | TRANSACTION_SYM
+ TRANSACTION can be a non-empty history unit, or can be an identifier
+ in bit_expr.
+
+ In the grammar below we use %prec to explicitly tell Bison to go
+ through the empty branch in the optional rule only when the lookahead
+ token does not belong to a small set of selected tokens.
+
+ Tokens NEXT_SYM and PREVIOUS_SYM also change their meaning from
+ identifiers to sequence operations when followed by VALUE_SYM:
+ SELECT NEXT VALUE FOR s1, PREVIOUS VALUE FOR s1;
+ but we don't need to list them here as they do not seem to cause
+ conflicts (according to bison -v), as both meanings
+ (as identifier, and as a sequence operation) are parts of the same target
+ column_default_non_parenthesized_expr, and there are no any optional
+ clauses between the start of column_default_non_parenthesized_expr
+ and until NEXT_SYM / PREVIOUS_SYM.

+
+ The partition grammar can be called from three places.
+ 1) CREATE TABLE ... PARTITION ..
+ 2) ALTER TABLE table_name PARTITION ...
+ 3) PARTITION ...
+
+ The first place is called when a new table is created from a MySQL client.
+ The second place is called when a table is altered with the ALTER TABLE
+ command from a MySQL client.
+ The third place is called when opening an frm file and finding partition
+ info in the .frm file. It is necessary to avoid allowing PARTITION to be
+ an allowed entry point for SQL client queries. This is arranged by setting
+ some state variables before arriving here.
+
+ To be able to handle errors we will only set error code in this code
+ and handle the error condition in the function calling the parser. This
+ is necessary to ensure we can also handle errors when calling the parser
+ from the openfrm function.

+ Expressions that the parser allows in a column DEFAULT clause

+ CREATE TABLE t1 (a TEXT DEFAULT 'a' COLLATE latin1_bin);
+ It would be not clear what COLLATE stands for:
+ - the collation of the column `a`, or
+ - the collation of the string literal 'a'
+
+ This restriction allows to parse the above query unambiguiusly:
+ COLLATE belongs to the column rather than the literal.
+ If one needs COLLATE to belong to the literal, parentheses must be used:
+ CREATE TABLE t1 (a TEXT DEFAULT ('a' COLLATE latin1_bin));
+ Note: the COLLATE clause is rather meaningless here, but the query
+ is syntactically correct.
+
+ Note, some of the expressions are not actually allowed in DEFAULT,
+ e.g. sum_expr, window_func_expr, ROW(...), VALUES().
+ We could move them to simple_expr, but that would make
+ these two queries return a different error messages:
+ CREATE TABLE t1 (a INT DEFAULT AVG(1));
+ CREATE TABLE t1 (a INT DEFAULT (AVG(1)));
