显示全部多分区诡异 的问题
db2 "select tabname,rows_read,overflow_accesses,dbpartitionnum from sysibmadm.snaptab where tabname='TABLE_A' "
TABNAME ROWS_READ OVERFLOW_ACCESSES DBPARTITIONNUM
-------------------------------------------------------------------------------------------------------------------------------- -------------------- -------------------- --------------
TABLE_A 1000 0 1
TABLE_A 3000 0 1
TABLE_A 4000 0 4
TABLE_A 2000 0 4
上面是多分区环境的部分结果
为什么每个分区都是2行结果，希望专家解读下
