Global statistics high/low values when using DBMS_STATS.COPY_TABLE_STATS

Read Original

This technical article discusses a known problem in Oracle's DBMS_STATS.COPY_TABLE_STATS procedure where high and low values of the partitioning key column are incorrectly copied between partitions. It covers the patch (8318020.8), explains the remaining issues with global statistics and value overlaps, and includes a demonstration SQL script for Oracle 11.1.0.7.
