1.Oracle：
select table_name
from user_tab_columns
where COLUMN_NAME= 'SAL'---查询数据库内所有包含sal列的表名
2.SqlServer
select table_name
from INFORMATION_SCHEMA.COLUMNS
where COLUMN_NAME= 'ksmc'
INTERSECT
select b.name
from sysindexes a ,
sysobjects b
where a.id = b.id
and a.indid < 2
and a.rowcnt > 0
and objectproperty(b.id, 'IsMSShipped') = 0-------查询数据库内包含某个列名，并且存在数据的表名
从整个数据库内查询含有某个字符串的表名（工作量极大，慎用）
