49255f5cbd MCOL-1482 An UPDATE operation on a non-ColumnStore table involving a 
cross-engine join with a ColumnStore table errors out.

ColumnStore cannot directly update a foreign table. We detect whether
a multi-table UPDATE operation is performed on a foreign table, if so,
do not create the select_handler and let the server execute the UPDATE
operation instead.

Fix regression in a query involving an aggregate function on a non-wide decimal column in the HAVING clause.
 2021-06-23 02:22:42 -04:00

7c8b502dc2 Fix regression in a query involving an aggregate function on a 
non-wide decimal column in the HAVING clause.

In buildAggregateColumn(), if an aggregate function (such as avg)
is applied on a non-wide decimal column, we were setting the precision
of the resulting column as -1. This later down in the execution got
converted to 255 as in some cases, precision is stored as uint8_t.
The predicate operations on a DECIMAL column has logic that uses
the wide Decimal::s128value field if precision > 18. This logic incorrectly
used the Decimal::s128value instead of the correct value stored in the
narrow Decimal::value field, since precision of the Decimal column
was 255. The fix is to set the aggregate column precision to
datatypes::INT64MAXPRECISION (18) in buildAggregateColumn() when the
aggregate is applied on a non-wide decimal column.

This commit also partially fixes -Wstrict-aliasing GCC warnings.

e3d8100150 MCOL-4525 Implement columnstore_select_handler=AUTO. 
This feature allows a query execution to fallback to the server,
in case query execution using the select_handler (SH) fails. In case
of fallback, a warning message containing the original reason for
query failure using SH is generated.

To accomplish this task, SH execution is moved to an earlier step when
we create the SH in create_columnstore_select_handler(), instead of the
previous call to SH execution in ha_columnstore_select_handler::init_scan().
This requires some pre-requisite steps that occur in the server in
JOIN::optimize() and JOIN::exec() to be performed before starting SH execution.

In addition, missing test cases from MCOL-424 are also added to the MTR suite,
and the corresponding fix using disable_indices_for_CEJ() is reverted back
since the original fix now appears to be redundant.
