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 sytem 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;
Note, we need here only tokens that cause shirt/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 explicitely 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.
