Oracle查询数据库中当前用户每个表的数据条数
select t.table_name,t.num_rows from user_tables t
一般情况下这条语句就可查出想要结果
如果不行
请执行以下脚本
create or replace function count_rows(table_name in varchar2, owner in varchar2 default null) return number authid current_user IS num_rows number; stmt varchar2(2000); begin if owner is null then stmt := 'select count(*) from "' || table_name || '"'; else stmt := 'select count(*) from "' || owner || '"."' || table_name || '"'; end if; execute immediate stmt into num_rows; return num_rows; end;
写了此方法以后在sql语句中调用即可
select table_name, count_rows(table_name) nrows from user_tables ;
