// As of 07/26/01, yacc (bison) reports for this file:
// w:\parser\sqlparser.y contains 56 shift/reduce conflicts and 9 reduce/reduce conflicts.

// shift/reduce case study: DROP GHOST TABLE
// Before the invention of ghost tables, the second production for drop_table_statement was:
//   drop_table_statement : TOK_DROP TOK_TABLE ddl_qualified_name optional_cleanup
//                            optional_drop_invalidate_dependent_behavior optional_validate optional_logfile
// I wanted to insert an optional TOK_GHOST like this:
//   drop_table_statement : TOK_DROP optional_ghost TOK_TABLE ddl_qualified_name optional_cleanup
//                            optional_drop_invalidate_dependent_behavior optional_validate optional_logfile
//   optional_ghost : empty | TOK_GHOST
// Unfortunately that introduced a shift/reduce conflict. After reading TOK_DROP, if the next 
// token is TOK_TABLE, bison wanted to reduce 
//   optional_ghost -> empty
// but it also wanted to shift TOK_TABLE because DROP TABLE was not enough to distinguish the 
// first two productions for drop_table_statement. So in order to avoid introducing a 
// shift/reduce conflict, the productions have been written like this:
//   drop_table_statement : drop_table_start_tokens ddl_qualified_name optional_cleanup
//                            optional_drop_invalidate_dependent_behavior optional_validate optional_logfile
//   drop_table_start_tokens : TOK_DROP TOK_TABLE | TOK_DROP TOK_GHOST TOK_TABLE
// This solves the problem because bison does not have to reduce after reading TOK_DROP. Rather,
// after reading TOK_DROP TOK_TABLE, it can lookahead at the next token to decide what to do.

 * we have distinct non-terminals for these various cases.  However, the

 * With the open cursor statement, only the preprocessor sees it, and the
 * preprocessor is designed to be able to translate the general case.
 *   We need merely to enforce certain constraints when we interpret
 * the parsed data (see the Preprocessor's dosql() routine).  Namely,
 * if the open cursor statement names the cursor statically, then there
 * can be no descriptor nor host variables named in the statement.  Conversely,
 * if there ARE host variables or descriptor named, then the cursor must
 * be designated by means of a name of a dynamic descriptor, or, by an
 * extended dynamic name given by a string valued host variable expression.
 * We can enforce that here in the parser.  The preprocessor code maps the
 * returned Statement Node to its internal structures for generating output.

// Host Variable Expression Formats
// --------------------------------
// Host variable expressions, in general, come in four varieties,
// depending on whether an indicator and/or prototype value is present
// (indicators may have a prototype value if the main host variable
// may have a prototype).  We denote these (), (I), (P), and (IP),
// which mean "no prototype, no indicator", "with indicator, but no
// prototype", and so on.
//
// Here are the uses of host variable expressions, then:
//   (P)   table names
//   (IP)  currently unused (candidate would for certain input host variables)
//   (I)   output host variables (which can't have prototype values)
//   ()    strings (i.e., prepare stmt), simple value spec, simple target
//           spec, and entity names (i.e., extended dynamic cursor)

// This non-terminal provides for host variable expressions of format "()"
// as given above.

/* NB: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
 *  Beware of adding clauses with a closing END like balance_expr above.
 *  They can mislead arkcmp/StaticCompiler.cpp's isEndOfStmt() and 
 *  sqlci/InputStmt.cpp's findBlockStmt() into finding the wrong END
 *  of a compound statement. For example:
 *     exec sql begin 
 *       insert into t values(7);
 *       select a into :h from m 
 *         sample first balance when a < 10 then 5 rows
 *                              when a >=10 then 7 rows
 *                      end sort by a;
 *     end;
 *  used to get a false syntax error due to a prematurely ENDed 
 *  compound statement. This is a consequence of SQLMX having 
 *  multiple parsers recognizing partially overlapping languages. To be
 *  more precise, both tdm_arkcmp and sqlci do only a partial scan of 
 *  their input looking for the beginning and ending of SQL statements 
 *  (among the input languages they recognize), ignore everything in
 *  between while buffering the statement, then passing it here 
 *  (sqlparser.y) for parsing. Therefore, the ending of SQLMX statements
 *  should be unambiguously distinguishable from the ending of compound
 *  statements. In case expressions "case .... end", we got away with it
 *  rather easily because "case" is an ANSI reserved word. But, for
 *  balance_expr, we had to solve the problem by considering "balance when" 
 *  as starting a new nesting level. But, "balance when" must be ignored 
 *  in "case balance when ... end" because "balance" here is an identifier
 *  and not a keyword. So, if you add any new clause with an "END" in it,
 *  please fix StaticCompiler.cpp and InputStmt.cpp also if your new 
 *  clause can appear inside a compound statement.

//	a,b=c,d    BUT NOT  a,b=(c,d)  or  (a,b)=c,d	[Tandem extension!]
//
// The latter cases still cause ambiguity parsing
//	select * from t1 join t2 on t1.a,t1.b = t2.aa,t2.bb, t3;
// but that is due to our non-Ansi extension; what we've fixed here is that
//	select * from t1 join t2 on t1.a = t2.aa, t3;
// will be parsed correctly per Ansi, as will
//	select * from t1 join t2 on (t1.a,t1.b) = (t2.aa,t2.bb), t3; -- Ansi
//	select * from t1 join t2 on (t1.a,t1.b = t2.aa,t2.bb), t3;   -- Tdm ext.

// The upshot in this set of rules is not to allow any bare
// <value_expression_list> on a RHS; instead, to clone each comparison operator
// rule with each of the three <value_expression, ve_list_comma, ve_list_paren>.
// Vive la balance!
//
// Do note that <row_subquery> is a <value_expression> of unknown degree, so we
// must allow it also wherever <ve_list_comma> or <ve_list_paren> may appear.
// 
// UDF added 1/8/10: Before UDF, only the first eight rules existed
// for this predicate.  Note that row_subquery is part of the
// value_expression rule, and the rule value_expression_list is made
// up of value_expression, value_expression_list_comma, and
// value_expression_list_paren.  Because of this you would think that
// only one rule would be needed:
//
//    value_expression_list comparison operator value_expression_list
//
// The beginning of this comment explains why this cannot be.  Since
// the first eight rules exist, and we cannot add rules like
//
//    value_expression comparison_operator value_expression_list_comma
//
// we must add explicit rules for multi-valued functions.  These are
// (co = comparison_operator):
//
//     value_expression_list_comma co '(' function ')'
//     value_expression_list_paren co '(' function ')'
//     '(' function ')' co value_expression_list_comma
//     '(' function ')' co value_expression_list_paren
//
// Unfortunately, we must also add the following as well:
//     value_expression co '(' function ')'
//     '(' function ')' co value_expression
//     row_subquery     co '(' function ')'

// This was added for JIRA Trafodion 2367. There are oddities in
// how PREPARE is parsed vs. how EXPLAIN is parsed, along with
// pecularities in the specific syntax of EXPLAIN that prevent
// us from recognizing the same identifiers for both. In sqlci,
// for example, sqlci's own parser picks off the PREPARE <identifier>
// part, and this parser only sees the query text afterwards. So,
// sqlci has its own rules for what <identifier>s are allowed.
// EXPLAIN on the other hand is fully parsed here in this parser.
// Trafci seems to have different processing yet. EXPLAIN itself
// has some confounding syntax: One can say "EXPLAIN <query text>"
// as well as "EXPLAIN <statement identifier>", so the identifier
// can conflict with any token that can start a statement. This
// anomaly is unique to EXPLAIN. That means that we can't simply
// plug in nonreserved_word as an alternative production for
// explain_identifier; we'll get a boatload of additional
// shift/reduce and reduce/reduce conflicts. It is possible in
// principle to create a subset of nonreserved_word for EXPLAIN,
// but in light of the fact that the PREPARE rules are in different
// parsers (and differ between sqlci and trafci), this seems a
// fool's errand.
// 
// So, up until this JIRA, only regular identifiers (that is,
// non-keywords) and delimited identifiers were allowed for EXPLAIN.
// Unfortunately, C is a keyword, since it is a language name on
// CREATE FUNCTION. So, EXPLAIN C; gives a syntax error. Since
// humans are sometimes prone to using one-letter identifiers,
// this can be highly irritating. So, to remove this irritation,
// we've supplied a separate nonreserved_word production just for
// EXPLAIN that contains all the one-letter tokens.

// Formerly declared as FUNC_ in ulexer.cpp keywordTable.  Now defined
// as nonreserved_func_word.  This works better and does not increase the
// shift reduce conflicts. When they were FUNC_s they were treated as
// IDENTIFIERs unless they were followed by a '('.  However, there are
// some contexts in which they should be treated as IDENTIFIERs even
// though they are followed by a '('.  For instance: "SELECT * from T
// ABS(a)".  In this case, ABS should be treated as an IDENTIFIER not
// a function name.
