Betreff: Re: why different users get different count(*) from same table?
Hi experts,
Something strange here, use root and mysql (root and mysql are user
accounts) to select count(*) from same table, but the result is different.
login as root:
mysql -uroot -p information_schema
mysql> select * from tables where table_name='tb_staff'\G
*************************** 1. row ***************************
TABLE_CATALOG: NULL
TABLE_SCHEMA: dbsg
TABLE_NAME: tb_staff
TABLE_TYPE: BASE TABLE
ENGINE: MyISAM
VERSION: 10
ROW_FORMAT: Dynamic
*TABLE_ROWS: 0*
AVG_ROW_LENGTH: 0
DATA_LENGTH: 0
MAX_DATA_LENGTH: 281474976710655
INDEX_LENGTH: 1024
DATA_FREE: 0
AUTO_INCREMENT: 1
CREATE_TIME: 2009-05-31 16:13:07
UPDATE_TIME: 2009-05-31 16:13:07
CHECK_TIME: NULL
TABLE_COLLATION: latin1_swedish_ci
CHECKSUM: NULL
CREATE_OPTIONS:
TABLE_COMMENT:
1 row in set (0.00 sec)
then,
login as mysql:
mysql -umysql -p information_schema
mysql> select * from tables where table_name='tb_staff'\G
*************************** 1. row ***************************
TABLE_CATALOG: NULL
TABLE_SCHEMA: dbsg
TABLE_NAME: tb_staff
