查询所有符合条件的表名：
（我这里的条件是所有以“tbl_”开头除过“tbl_user"的所有表名）
create or replace function query_all_table_name() returns setof varchar as
$$
declare
select_result record;
begin
for select_result in
select tablename from ux_tables where tablename like 'tbl_%' and tablename != 'tbl_user'
loop
return next select_result.tablename;
end loop;
return;
end;
$$
language pluxsql volatile
cost 100 rows 1000;
删除所有符合条件的表的数据：
（我这里是删除上边查出的这些表的数据）
create or replace function clear_table_data() returns text as
$$
declare
select_result record;
table_name varchar;
begin
for select_result in
select tablename from ux_tables where tablename like 'tbl_%' and tablename != 'tbl_user'
loop
table_name = select_result.tablename;
execute 'delete from ' || table_name;
end loop;
return 'success';
