WF::percentile runtime threw an exception b/c of wrong DT deduced from its argument
Replaced literals with constants
Tought WF_sum_avg::checkSumLimit to use refs instead of values
This commit also adds support in TupleHashJoinStep::forwardCPData,
although we currently do not support wide decimals as join keys.
Row estimation to determine large-side of the join is also updated.
Introduced fDecimalOverflowCheck to enable/disable overflow check.
Add support into a FunctionColumn.
Low level scanning crashes on medium sized data sets.
2. Set Decimal precision in SimpleColumn::evaluate().
3. Add support for int128_t in ConstantColumn.
4. Set IDB_Decimal::s128Value in buildDecimalColumn().
5. Use width 16 as first if predicate for branching based on decimal width.
This commit introduces DataConvert UTs.
DataConvert::decimalToString now can negative values.
Next version for Row::toString(), applyMapping UT checks.
Row:equals() is now wide-DECIMAL aware.
CREATE TABLE. ZEROFILL is dummy though.
There is a new file with column width utilities.
Array access was replaced by a variable that is calculated only once in
TupleJoiner::updateCPData.
Replaced BINARYEMPTYROW and BINARYNULL values. We need to have
separate magic values for numeric and non-numeric binary types
b/c numeric cant tolerate losing 0 used for magics previously.
atoi128() now parses minus sign and produces negative values.
RowAggregation::isNull() now uses Row::isNull() for DECIMAL.
TupleAggregateStep class method and buildAggregateColumn() now properly set result data type.
doSum() now handles DECIMAL(38) in approprate manner.
Low-level null related methods for new binary-based datatypes now handles magic values for
binary-based DT.
There are multiple overloaded version of the low level DML write methods to
push down CSC column type. WE needs the type to convert values correctly.
Replaced WE_INT128 with CSC data type that is more informative.
Removed commented and obsolete code.
Replaced switch-case blocks with oneliners.
