Parses a parenthesized query or comma-list of row expressions.

REVIEW jvs 8-Feb-2004: There's a small hole in this production. It can be used to construct something like WHERE x IN (select count(*) from t where c=d,5), which should be illegal. The above is interpreted as equivalent to WHERE x IN ((select count(*) from t where c=d),5), which is a legal use of a subquery. The only way to fix the hole is to be able to remember whether a subexpression was parenthesized or not, which means preserving parentheses in the SqlNode tree. This is probably desirable anyway for use in purely syntactic parsing applications (e.g. SQL pretty-printer). However, if this is done, it's important to also make isA() on the paren node call down to its operand so that we can always correctly discriminate a query from a row expression.

Parses a binary row expression, or a parenthesized expression of any kind.

The result is as a flat list of operators and operands. The top-level call to get an expression should call Expression(org.apache.calcite.sql.parser.SqlAbstractParserImpl.ExprContext), but lower-level calls should call this, to give the parser the opos to associate operator calls.

For example 'a = b like c = d' should come out '((a = b) like c) = d' because LIKE and '=' have the same precedence, but tends to come out as '(a = b) like (c = d)' because (a = b) and (c = d) are parsed as separate expressions.

Parses a call to a named function (could be a builtin with regular syntax, or else a UDF).

NOTE: every UDF has two names: an invocation name and a specific name. Normally, function calls are resolved via overload resolution and invocation names. The SPECIFIC prefix allows overload resolution to be bypassed. Note that usage of the SPECIFIC prefix in queries is non-standard; it is used internally by Farrago, e.g. in stored view definitions to permanently bind references to a particular function after the overload resolution performed by view creation.

TODO jvs 25-Mar-2005: Once we have SQL-Flagger support, flag SPECIFIC as non-standard.

ParseException

Parses a non-reserved keyword for use as an identifier. Specializations of this parser can use this as a base for implementing the NonReservedKeyWord() production.

When adding keywords to this list, be sure that they are not reserved by the SQL:2003 standard (see productions for "non-reserved word" and "reserved word" in reference below).

Throws:

ParseException

UnusedExtension

public final void UnusedExtension()
                           throws ParseException

Defines a production which can never be accepted by the parser. In effect, it tells the parser, "If you got here, you've gone too far." It is used as the default production for parser extension points; derived parsers replace it with a real production when they want to implement a particular extension point.
