+

+  These two declarations are different:
+    x INT;
+    ROW(x INT);
+  A ROW with one elements should not be comparable to scalar value.
+
+  TODO: Currently we don't support one argument with the function ROW(), so
+  this query returns a syntax error, meaning that more arguments are expected:
+    SELECT ROW(1);
+
+  Therefore, all around the code we assume that cols()==1 means a scalar value
+  and cols()>1 means a ROW value. With adding ROW SP variables this
+  assumption is not true any more. ROW variables with one element are
+  now possible.
+
+  To implement Item::check_cols() correctly, we now should extend it to
+  know if a ROW or a scalar value is being tested. For example,
+  these new prototypes should work:
+    virtual bool check_cols(Item_result result, uint c);
+  or
+    virtual bool check_cols(const Type_handler *type, uint c);
+
+  The current implementation of Item_splocal::check_cols() is a compromise
+  that should be more or less fine until we extend check_cols().
+  It disallows ROW variables to appear in a scalar context.
+  The "|| n == 1" part of the conditon is responsible for this.
+  For example, it disallows ROW variables to appear in SELECT list:
+
+DELIMITER $$;
+CREATE PROCEDURE p1()
+AS
+  a ROW (a INT);
+BEGIN
+  SELECT a;
+END;
+$$
+DELIMITER ;$$
+--error ER_OPERAND_COLUMNS
+CALL p1();
+
+  But is produces false negatives with ROW variables consisting of one element.
+  For example, this script fails:
+
+SET sql_mode=ORACLE;
+DROP PROCEDURE IF EXISTS p1;
+DELIMITER $$
+CREATE PROCEDURE p1
+AS
+  a ROW(a INT);
+  b ROW(a INT);
+BEGIN
+  SELECT a=b;
+END;
+$$
+DELIMITER ;
+CALL p1();
+
+  and returns "ERROR 1241 (21000): Operand should contain 1 column(s)".
+  This will be fixed that we change check_cols().

+    This method is used in data type aggregation for UNION, e.g.:
+      SELECT 'b' UNION SELECT COALESCE(double_10_3_field) FROM t1;
+
+    The result is usually equal to max_length, except for some numeric types.
+    In case of the INT, FLOAT, DOUBLE data types Item::max_length and
+    Item::decimals are ignored, so the returned value depends only on the
+    data type itself. E.g. for an expression of the DOUBLE(10,3) data type,
+    the result is always 53 (length 10 and precision 3 do not matter).
+
+    max_length is ignored for these numeric data types because the length limit
+    means only "expected maximum length", it is not a hard limit, so it does
+    not impose any data truncation. E.g. a column of the type INT(4) can
+    normally store big values up to 2147483647 without truncation. When we're
+    aggregating such column for UNION it's important to create a long enough
+    result column, not to lose any data.
+
+    For detailed behaviour of various data types see implementations of
+    the corresponding Type_handler_xxx::max_display_length().

-      (i.e. a column is stronger than a string constant,

-  @brief Aggregates field types from the array of items.
-
-  @param[in] items  array of items to aggregate the type from
-  @paran[in] nitems number of items in the array
-  @param[in] treat_bit_as_number - if BIT should be aggregated to a non-BIT
-             counterpart as a LONGLONG number or as a VARBINARY string.
-
-             Currently behaviour depends on the function:
-             - LEAST/GREATEST treat BIT as VARBINARY when
-               aggregating with a non-BIT counterpart.
-               Note, UNION also works this way.
-
-             - CASE, COALESCE, IF, IFNULL treat BIT as LONGLONG when
-               aggregating with a non-BIT counterpart;
-

+/**
+  A helper class to handle situations when some item "pred" (the predicant)
+  is consequently compared to a list of other items value0..valueN (the values).
+  Currently used to handle:
+  - <in predicate>
+    pred IN (value0, value1, value2)
+  - <simple case>
+    CASE pred WHEN value0 .. WHEN value1 .. WHEN value2 .. END
+
+  Every pair {pred,valueN} can be compared by its own Type_handler.
+  Some pairs can use the same Type_handler.
+  In cases when all pairs use exactly the same Type_handler,
+  we say "all types are compatible".
+
+  For example, for an expression
+    1 IN (1, 1e0, 1.0, 2)
+  - pred   is 1
+  - value0 is 1
+  - value1 is 1e0
+  - value2 is 1.1
+  - value3 is 2
+
+  Pairs (pred,valueN) are compared as follows:
+    N   expr1  Type
+    -   -----  ----
+    0       1   INT
+    1     1e0   DOUBLE
+    2     1.0   DECIMAL
+    3       2   INT
+
+  Types are not compatible in this example.
+
+  During add_value() calls, each pair {pred,valueN} is analysed:
+  - If valueN is an explicit NULL, it can be ignored in the caller asks to do so
+  - If valueN is not an explicit NULL (or if the caller didn't ask to skip
+    NULLs), then the value add an element in the array m_comparators[].
+
+  Every element m_comparators[] stores the following information:
+  1. m_arg_index - the position of the value expression in the original
+     argument array, e.g. in Item_func_in::args[] or Item_func_case::args[].
+
+  2. m_handler - the pointer to the data type handler that the owner
+     will use to compare the pair {args[m_predicate_index],args[m_arg_index]}.
+
+  3. m_handler_index - the index of an m_comparators[] element corresponding
+     to the leftmost pair that uses exactly the same Type_handler for
+     comparison. m_handler_index helps to maintain unique data type handlers.
+   - m_comparators[i].m_handler_index==i means that this is the
+     leftmost pair that uses the Type_handler m_handler for comparision.
+   - If m_comparators[i].m_handlex_index!=i, it means that some earlier
+     element m_comparators[j<i] is already using this Type_handler
+     pointed by m_handler.
+
+  4. m_cmp_item - the pointer to a cmp_item instance to handle comparison
+     for this pair. Only unique type handlers have m_cmp_item!=NULL.
+     Non-unique type handlers share the same cmp_item instance.
+     For all m_comparators[] elements the following assersion it true:

+    - An application uses select foo(), and works.
+    - MySQL 5.{N+1} defines a new native function 'foo', as

+    - 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

+  @brief Aggregates field types from the array of items.
+
+  @param[in] items  array of items to aggregate the type from
+  @param[in] nitems number of items in the array
+  @param[in] treat_bit_as_number - if BIT should be aggregated to a non-BIT
+             counterpart as a LONGLONG number or as a VARBINARY string.
+
+             Currently behaviour depends on the function:
+             - LEAST/GREATEST treat BIT as VARBINARY when
+               aggregating with a non-BIT counterpart.
+               Note, UNION also works this way.
+
+             - CASE, COALESCE, IF, IFNULL treat BIT as LONGLONG when
+               aggregating with a non-BIT counterpart;
+
+             This inconsistency may be changed in the future. See MDEV-8867.
+
+             Note, independently from "treat_bit_as_number":
+             - a single BIT argument gives BIT as a result
+             - two BIT couterparts give BIT as a result
+
+  @details This function aggregates field types from the array of items.
+    Found type is supposed to be used later as the result field type
+    of a multi-argument function.
+    Aggregation itself is performed by Type_handler::aggregate_for_result().
+
+  @note The term "aggregation" is used here in the sense of inferring the
+    result type of a function from its argument types.
+
+  @retval false - on success
+  @retval true  - on error

-                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.

+  @brief Bison callback to report a syntax/OOM error
+
+  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.

+ This part of the parser is about handling of the partition information.
+
+ It's first version was written by Mikael Ronstrm with lots of answers to
+ questions provided by Antony Curtis.
+
+ 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
+  without parentheses. These expressions cannot end with a COLLATE clause.
+
+  If we allowed any "expr" in DEFAULT clause, there would be a confusion
+  in queries like this:
+    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)));
+  The first query would return "syntax error".
+  Currenly both return:
+   Function or expression 'avg(' is not allowed for 'DEFAULT' ...
