translate 'In' operator in SQL to LINQ

Just found out there is no 'In' in LINQ, instead there is an ANY in LINQ:
e.g.
var abc=
from d in mydb.department
where mydb.employee.Any(e => e.ProductID == d.ManagerId)
select d;

OUTKAST - PROTOTYPE

I hope that you're the one
If not, you are the prototype
We'll tiptoe to the sun
And do thangs I know you like

[Hook]
I think I'm in love again [repeat]

[Hook]

[Verse 2]
If we happen to part

But hey, we can't be mad at God
We met today for a reason
I think I'm on the right track now

[Hook]

The Scene

[Outro (ad libs)]
Girl, right now I wanna say, I wanna say
I wanna say stank you very much
For picking me up
And bringing me back to this world
I can't, I'm not
I can't afford to not record
I thank I wanna say
I thank I wanna say stank you, stank you
Smelly much!
For picking me up and bringing me back to this world
Hey, hey John! Are we recording our ad libs?
Really?? Were we recording just then?
Let me hear that, that first one
When I first started

不归路

歌曲：不归路

歌手：迪克牛仔

专辑：忘记我还是忘记他

词∶许常德　曲∶林进璋


我没有退路

尽管你也千辛万苦

不愿认输

是良心让爱坚固

剩下由老天做主

爱你是一条不归路

一度我非常孤独

但是我更怕漂浮

不知道身在何处

有时候绝路也是人生一条路

爱让人全意付出忘记有结束

一心只想你幸福

疏忽了自己痛苦

我没有退路

尽管你也千辛万苦

不愿认输

是良心让爱坚固

剩下由老天做主

有時候错误也是人生一条路

谁不是跌到谷底才有点觉悟

只要你不想退出

我不怕命运残酷

我没有退路

尽管你也千辛万苦

不愿认输

是良心让爱坚固

剩下由老天做主

我没有退路

尽管我也千辛万苦也不愿认输

是良心让爱坚固

老天做主

爱是心中唯一不变美丽的神话

美丽的神话-孙楠，韩虹

梦中的人熟悉的脸孔
你是我守候的温柔
就算泪水淹没天地
我不会放手,每一刻孤独的承受
只因我曾许下承诺
你我之间熟悉的感动
爱就要苏醒
万世沧桑唯有爱是永远的神话
潮起潮落始终不悔真爱的相约
几番若痛的纠缠多少黑夜掐扎
紧握双手让我和你再也不离分
枕上雪冰封的爱恋
真心相摇篮才能融解
风中摇曳炉上的火
不灭亦不休
等待花开春去春又来
无情岁月笑我痴狂
心如钢铁任世界荒芜
思念永相随
悲欢负月唯有爱是永远的神话
谁都没有遗忘古老,古老的誓言
你的泪水化为漫天飞舞的彩蝶
爱是翼下之风两心相随自在飞
你就是我心中唯一美丽的神话

爱情诺曼底

六月六日六时六分刚过六十秒
脆弱的堡垒远眺如风化的沙雕
轻抚着断裂的皱纹沧桑一条条
谁的心早已死掉
曾和你相爱如天命难违的凑巧
为何与你对决变成轮回的纷扰
爱如那常消的海潮退去时飘渺
我的心不再计较
情爱它似毒药 你我早就应该知道
为何却不停的要
为何却一再的要
我怎么才能登上你的爱情诺曼底
别让天与海的距离 衡量爱与恨的对立
怎么才能让我登上你的爱情诺曼底
狂奔在破晓的大地 拼了命也要找到你
占领这爱情诺曼底 Yeah

挑衅

我的梦早已归零 我的爱结成冰

退色的刺青 残留的姓名 那是我的曾经

别为我动了真情 别怪我那么ㄍㄧㄥ

孤独的背影 落寞的神情 经不起你的挑衅

不要闯进我冰冷的爱情 我怕沉睡的梦被你惊醒

无论束手就擒 或是抵挡你的入侵 都会让我 摇摆不定 触景伤情

你的梦如此清醒 你的爱太冷静

催泪的叮咛 温柔的神情 却又让我动心

别让我掉入陷阱 别恨我不敢听

固执的个性 坚定的表情 经不起你的挑衅

不要闯进我冰冷的爱情 我怕沉睡的梦被你惊醒

无论束手就擒 或是抵挡你的入侵 对我来说 都是挑衅

不要挑衅我冰冷的爱情 我怕醒来会爱你爱不停

请你别再靠近 不要让我恨不下心

现在的我 经不起你 一再挑衅

check all or none items in checkedlistbox

if (clientList.CheckedItems.Count == 0)
for (int i = 0; i < clientList.Items.Count; i++)
{
clientList.SetItemChecked(i, true);
}
else
for (int i = 0; i < clientList.Items.Count; i++)
{
clientList.SetItemChecked(i, false);
}

Visual Studio 2008 checkedlistbox

figured this way to databind checkedlistbox, not sure why DataSourse, ValueMember, and DisplayMember do not appear in intellisense

this.clientsTableAdapter.Fill(this.dataSet1.Clients);
practice2.DataSet1.ClientsDataTable t = clientsTableAdapter.GetData();
checkedListBox1.DataSource = t;
checkedListBox1.ValueMember = t.IdColumn.ColumnName;
checkedListBox1.DisplayMember = t.NameColumn.ColumnName;

ORA-00979: not a GROUP BY expression

problem query

select class_schedule.class_id, class_schedule.sum(class_schedule.enrolments) tot_enr, class.name from class_schedule inner join class on class_schedule.class_id = class.id group by class_schedule.class.id

solution

select class_schedule.class_id,
sum(class_schedule.enrolments) tot_enr, class.name
from class_schedule
inner join
class on class_schedule.class_id = class.id
group by class_schedule.class_id, class.name

how to convert my query to stored procedure

I have this procedure below:

set serveroutput on
DECLARE
v_counter NUMBER(7) := 0;
v_tax NUMBER(11,2) := 0;
v_an_sal NUMBER(11,2) := 0;
CURSOR emp_cursor IS

I need to convert it to a stored procedure (or create a sored procedure for this) so that i can call it from my psp pages.

solution:
remove 'DECLARE set serveroutput on'
replace with 'CREATE OR REPLACE PROCEDURE proc_emp_sum_analysis AS'

loop through query result and print each row in stored procedure

have this query which returns a set of rows, How can I loop through each row and display them using dbms.output.put_line? Please notice in the where clause there is a variable 'v_trainer_id', the variable value is known (retrieved from a column of a current row of another cursor)

select customer.id as customer_id, membership.join_date, membership.join_fee,round(months_between(sysdate, membership.join_date),0) as months_joined, membership_plan.monthly_price, membership.monthly_discount, (membership_plan.monthly_price- membership.monthly_discount) * round(months_between(sysdate, membership.join_date),0) as total_paidfrom membership,membership_plan,customerwhere membership.membership_plan_id = membership_plan.id andcustomer.id=membership.customer_id andmembership.trainer_id = v_trainer_idorder bycustomer.id;

solution:

v_cur_tid := r_trainer.trainer_id;FOR r_mem IN(select membership.customer_id as cust_id, membership.join_date, membership.join_fee,round(months_between(sysdate, membership.join_date),0) as months_joined, membership_plan.monthly_price, membership.monthly_discount, (membership_plan.monthly_price- membership.monthly_discount) * round(months_between(sysdate, membership.join_date),0) as total_paidfrom membership,membership_planwhere membership.membership_plan_id = membership_plan.id andmembership.trainer_id = v_cur_tidorder bymembership.customer_id)LOOP

PL/SQL: ORA-01744: inappropriate INTO

I have this part of the stored procedure, trying to use one select query to fill in 2 variables, got error 'PL/SQL: ORA-01744: inappropriate INTO'

--print summary of subsection

select t.* from (select count(membership.id) into v_tot_mem_by_trainer,sum((membership_plan.monthly_price- membership.monthly_discount) * round(months_between(sysdate, membership.join_date),0)) into v_tot_rev_by_trainerfrom membership, membership_planwhere membership.trainer_id = r_trainer.trainer_id andmembership.membership_plan_id = membership_plan.id) t;

this is the original select query that has no problem

select t.* from (select count(membership.id) as total_number_of_members,sum((membership_plan.monthly_price- membership.monthly_discount) * round(months_between(sysdate, membership.join_date),0)) as total_membership_paymentfrom membership, membership_planwhere membership.membership_plan_id = membership_plan.id) t;

the solution:

select t.* into v_tot_mem_by_trainer, v_tot_rev_by_trainer from (select count(membership.id),sum((membership_plan.monthly_price- membership.monthly_discount) * round(months_between(sysdate, membership.join_date),0))from membership, membership_planwhere membership.trainer_id = r_trainer.trainer_id andmembership.membership_plan_id = membership_plan.id) t;

ORA-00937: not a single-group group function

I want to select some data from table membership and membership_plan, these 2 have some relationships with each other. In the same query, I also want to 'select count(*) from customers' where customers table has no relationship with the other 2 tables, I just want to find out the total number of customers and display with the rest of the query results.

select (select count(id) from customer), count(membership.id) as total_number_of_members, sum((membership_plan.monthly_price- membership.monthly_discount) * round(months_between(sysdate, membership.join_date),0)) as total_all_members from membership,membership_planwhere membership.membership_plan_id = membership_plan.id;

I got an error message as below:
ERROR at line 1:ORA-00937: not a single-group group function

solution:

select (select count(id) from customer), t.* from (select count(membership.id) as total_number_of_members,
sum((membership_plan.monthly_price- membership.monthly_discount) * round(months_between(sysdate, membership.join_date),0)) as total_all_members
from membership, membership_plan
where membership.membership_plan_id = membership_plan.id) t;
