Description:
The following query over I_S tables returns different (incorrect) result
when executed under Windows:
select * from information_schema.statistics join information_schema.columns
using(table_name,column_name) where table_name='user';
The query is introduced in 'join.test' as part of the test for BUG#17523.
The result on Linux is:
TABLE_NAME COLUMN_NAME TABLE_CATALOG TABLE_SCHEMA NON_UNIQUE INDEX_SCHEMA INDEX_NAME SEQ_IN_INDEX COLLATION CARDINALITY SUB_PART PACKED NULLABLE INDEX_TYPE COMMENT TABLE_CATALOG TABLE_SCHEMA ORDINAL_POSITION COLUMN_DEFAULT IS_NULLABLE DATA_TYPE CHARACTER_MAXIMUM_LENGTH CHARACTER_OCTET_LENGTH NUMERIC_PRECISION NUMERIC_SCALE CHARACTER_SET_NAME COLLATION_NAME COLUMN_TYPE COLUMN_KEY EXTRA PRIVILEGES COLUMN_COMMENT

The result on Windows is:
