一个包含pk和status列的表,其值为'Y','N','NULL'
查询:
获取状态栏为“Y”的记录计数,如果此计数超过记录总数的1%则不删除,否则删除表中的记录。
我试过这个
Declare
v_count Number;
v_count1 Number;
BEGIN
v_count := select count(*) from temp;
v_count1 := select count(*) from temp where status = 'Y' ;
v_count := v_count + ((0.1) * (v_count))
if (v_count1 > v_count)
{
insert into temp1 values(pk,status)
}
else
{
Delete from temp ;
}
END;
答案 0 :(得分:0)
Declare
v_count Number;
v_count1 Number;
BEGIN
select count(*) into v_count from temp;
select count(*) into v_count1 from temp where status = 'Y' ;
v_count := v_count + ((0.01) * (v_count))
if (v_count1 > v_count)
{
insert into temp1 values(pk,status)
}
else
{
Delete from temp ;
}
END;
更正你的函数这样的SQL查询.......享受
