2009-10-28 Marek Habersack <mhabersack@novell.com>
* Tokenizer.cs, Parser.jay: a work around for 3 reduce/reduce
conflicts (use of 'NOT LIKE' and 'NOT IN' which would previously
be ignored because of the conflicts). The grammar still has 6 more
of those - the real fix is to rewrite it.
2009-07-23 Adam Wendt <adam@awendtconsulting.com>
* Comparison.cs (Compare): Parse string if other object is DateTime
regardless of which side the DateTime is on.
2008-08-18 Marek Habersack <mhabersack@novell.com>
* Numeric.cs: Max/Min operations do not convert string
IConvertibles to double - they perform a simple string compare
instead.
2008-01-23 Konstantin Triger <kostat@mainsoft.com>
* Like.cs: when rh expresssion is null or DBNull always return false.
2007-12-24 Konstantin Triger <kostat@mainsoft.com>
* Parser.jay, StringFunctions.cs, Like.cs: add support for string concat.
2007-07-26 Nagappan A <anagappan@novell.com>
* Comparison.cs (Compare): Should always parse the object of type
DateTime in InvariantCulture CultureInfo, Fixes Bug # 82109.
2007-06-06 Nagappan A <anagappan@novell.com>
* ColumnReference.cs (Unify): Return object as it is, if object
type is char. Fixes bug # 81625.
* Numeric.cs (IsNumeric): Return false if object type is
char. Fixes bug # 81625.
2007-02-23 Nagappan A <anagappan@novell.com>

after that.
2006-05-02 Senganal T <tsenganal@novell.com>

* Aggregation.cs: fix possible NullReferenceException.
2006-02-03 Senganal T <tsenganal@novell.com>
* ColumnReference.cs :
- GetReferencedRow ()
- GetReferencedRows() : Verify the column before getting the values.
Validate the ColumnReference even when the table has no rows.

around to return DBNull.Value.
2006-01-18 Boris Kirzner <borisk@mainsoft.com>
* ColumnReference.cs: added column and relation lazy evaluation
and caching.
2006-01-09 Senganal T <tsenganal@novell.com>

and GetHashCode() methods for all Mono.Data.SqlExpressions classes,enabling
comparison of the filter expressions.
2005-08-02 Sureshkumar T <tsureshkumar@novell.com>
* Tokenizer.cs: ReadString (): added an overload where the
terminator can be escaped by repeating twice.
2005-06-29 Sureshkumar T <tsureshkumar@novell.com>
* ArithmeticExpressions.cs: Eval :if any one of the argument is

conversion from object.
