SELECT from two tables

Hello, I have a problem writing to a specific SELECT statement and I hope you can help me.

I have two tables:

Customer:

-Integer ID (PK)
-Name_SecondName varchar (20)
-Char sex
-Full scale

Investments:

-Integer ID (PK)
-Whole amount
-Interest Numeric (3.2)
-Client_ID (FK)

My job is to display a number of men and a few women who have at least a $ 1000 investment. I'll jump to add data to the table, my point is simply to find a correct interpretation of the SQL query. Right now I have this:

SELECT COUNT (DISTINCT Client_ID), COUNT (DISTINCT Client_ID)
SOME customers JOIN investments
WE Clients.ID = Investments.Client_ID
WHERE amount > 1000;

Of course, it displays twice the number of clients thanks to an investment of more than $ 1000. But how do I specify that the first indictment counts men (sex = am') and second - women (sex = 'F')? Can someone help me?

Hello

Here's a way to do

SELECT       COUNT (DISTINCT CASE WHEN c.gender = 'M' THEN c.client_id END)     AS men
,       COUNT (DISTINCT CASE WHEN c.gender = 'F' THEN c.client_id END)     AS women
FROM       clients       c
JOIN       investments       i  ON       c.client_id  = i.client_id
WHERE       i.amount       >= 1000
;

This query will work in Oracle 8.1 or more.
Since you have Oracle 11, you can also use the SELECT... Function pivot, but in this case, it's more complicated. That's because what to CHOOSE... PIVOT includes automatically by each column that is not involved in the pivot. (In this case, this means that all except sex and client_id columns.) Often, you do sort of a subquery to get the dynamic no cross data, so it is easy to include only the relevant columns. In this case, however, you need not any kind of subquery, so you should add a fair to exclude the additional columns if you want to use SELECT... PIVOT.

As you say in your original post, this account of customers who have any single investment of 1000 or more. In your last post, you posted a query that looks for investments of more than 15,000. You can change the WHERE clause to say

WHERE       i.amount       >  15000

but which would produce 0 men and 0 women, given that all of the amounts in the sample data are 10000.

Is it possible to display the entire word 'Genre' and not only "G"?

Sure.

SQL * automatically sizes string columns to their maximum size. Since between the sexes are defined as CHAR (1), its maximum size is 1 character, then SQL * Plus allocates only 1 space for her, truncate the heading after 1 character. You can explicitly set the width on anything it is large enough to show the entire title, like this:

COLUMN  gender  FORMAT  A6

Include this command before you run the query. Then, SQL * Plus uses 6 places to display the sex, so there will be place for all 6 characters in the heading.

I wonder you can not create a report by selecting from multiple tables?
If you can please I need your help.
Thank you

You can, but in this case, it might be easier to build your report tables that are joined Oracle views and then build your report out of the newly built sight...

Or wrap a selection around your selection with joins, and then make the where clause on the external selection...

Extraction of data from two tables without discounting
Hi friends,

I have a problem I want to extract data from two tables without discount in the text field when I will enter any value in a text field, then the value of corressponding must come to textfield corressponding.

for example. There are two table A and B.
Table A has Colunm

S_ID number;
C_ID Varchar2 (30);
VARCHAR2 (4) s;

Second table B Colunm name

S_ID number;
What varchar (30);
L_Name varchar (20);

When I enter in a text field then the c_id 101 s_id, dry, first_name and last_name should come to corressponding text without refresh fields.

How can I do that.

Thank you
Maury
You can use Ajax and there are tons of good examples out there for this purpose;

Extract single line transformed from two tables

I have two tables T1 and T2 with the same set of columns. The columns are C1, C2, C3, COND1. I need to issue a query that returns a line transformed in order to respect the following rules:
1. the returned line may contain values from both tables based on the values of column in table T1.
2 return the column C1 in table T1; If it is NULL, then return to any value is present in the column C1 of T2.
3. article 2 above apply to all columns like C1, C2 etc.
I published the following query. The problem is that if a subquery does not reach the entire query fails. Someone help me please. Probably there is another simple method.
SELECT NVL (T1.c1, T2.c1) c1, c2 (T1.c2, T2.c2) NVL NVL (T1.c3, T2.c3) c3

FROM (SELECT c1, c2, c3

FROM T1

WHERE cond1 = 'T10') T1

(SELECT c1, c2, c3

THE T2

WHERE cond1 = "T200") T2;

Are you saying that if there is no row in t1 that satisfy the condition cond1 = "T10", then you want to keep seeing the lines (and values) of the t2?

And even, if there is no row in t2 that satisfy the cond1 = "T200" condition, then you want to keep seeing the lines (and values) from t1?

If so, this looks like a job for a full outer join.

You can change the join in a full outer join as follows:

SELECT NVL (T1.c1, T2.c1) AS c1

, NVL (T1.c2, T2.c2) C2

NVL (T1.c3, T2.c3) AS c3

FROM T1

FULL OUTER JOIN T2 ON t1.cond1 = 'T10 '.

AND t2.cond1 = 'T200.

WHERE t1.cond1 = 'T10 '.

OR t2.cond1 = "T200"

;

If you would care to post CREATE TABLE and INSERT instructions for some examples of data, then I could test this.

What happens if no table has all the lines that have good values in cond1?

Find unmatched columns from two tables
Hello guys,.

I am trying to compare two tables based on a key of the indexed columns.

Here is an example of what I'm trying to achieve:

Table A: A_ID A_Name A_Income A_housecount
Jess 11 9 2
Rauny 4 6 22

Table b: B_ID B_Income B_housecount
11-5-2
22 6 4
In the example above data columns A_ID and B_Id are same in both tables. I'm trying to compare A_Income with B_Income & & A_housecount with B_housecount. The results of this series of samples would be:

11-9-2
11-5-2

as income in the same id is different.

As I have large amount of data in the two tables can you please give me some ideas on how I can get my results? Let me know if the explanation is not clear for you.

Thanks in advance
```

Display data from two tables based on date criteria

Hi all

I have two tables, using these two tables and a few conditions I want to recover under result. Oracle version is (Oracle9i Enterprise Edition Release 9.2.0.8.0 - 64 bit Production)

LOGON_ID        USER_ID       LOGON_TIME                 LOGON_TYPE    SUBSCRIBER_NO               CUSTOMER_ID

26063548     4528890298   4/5/2010 12:03:58 AM            MSISDN       GSM04528890298              581751708

logon_histories_r table records the information of each user who connects to the system. Subscriber Details table contains all the information corresponding to subscriber_no, only 1 row should be returned.
I'm confused usage date condition for the table of the Subscriber, the input parameter date 04/04/2006 to 15/04/06

Select lh.logon_id, lh.user_id, lh.logon_time, lh.logon_type, subs.subscriber_no, subs.customer_id
of logon_histories_r lh, subscribed subs
where lh.logon_time > = to_date('05-04-2010','dd-mm-yyyy')--to_date('04-04-2006','dd-mm-yyyy')
and lh.logon_time < to_date('06-04-2010','dd-mm-yyyy')--to_date('15-01-2007','dd-mm-yyyy')
and lh.user_id = substr (subs.subscriber_no,-10);

If the date range is 04/05/2010 to 04/06/2010 then the data related to the BAN 581751708 must be the result,
If the date range is 04/04/2006 to 15/01/2007 data related to the BAN 502499502 must be the result.

Please find DDL and data relevant to these results. There are millions of records of Subscriber & logon_histories_r table, I am given appropriate providing a subscriber_id.

Hello

Welcome to the froum!

Thanks for posting the CREATE TABLE and INSERT! It's very nigra.

user12990691 wrote:
...
logon_histories_r table records the information of each user who connects to the system. Subscriber Details table contains all the information corresponding to subscriber_no, only 1 row should be returned.

Do you mean a line by the user, or a line every time that you run the report, regardless of the number of users connected during the period that interests us?
Anyway, if there are multiple logons, how do you decide that one? Or the output of logon_histories_r columns will be a sort of composite?

I'm confused usage date condition for the table of the Subscriber, the input parameter date 04/04/2006 to 15/04/06

Select lh.logon_id, lh.user_id, lh.logon_time, lh.logon_type, subs.subscriber_no, subs.customer_id
of logon_histories_r lh, subscribed subs
where lh.logon_time > = to_date('05-04-2010','dd-mm-yyyy')--to_date('04-04-2006','dd-mm-yyyy')
and lh.logon_time< to_date('06-04-2010','dd-mm-yyyy')="" --="">
and lh.user_id = substr (subs.subscriber_no,-10);

Must LH.LOGON_TIME match something in the subscruber table? If so, you need to addsome extra join pathological.
For example, if lh.logon_time must be between d1 and d2 (where d1 and d2 are DATE columns), then:

select      lh.logon_id
,     lh.user_id
,     lh.logon_time
,     lh.logon_type
,     subs.subscriber_no
,     subs.customer_id
from      logon_histories_r      lh
,      subscriber           subs
where      lh.logon_time      >= to_date ('05-04-2010','dd-mm-yyyy') -- to_date('04-04-2006','dd-mm-yyyy')
and      lh.logon_time      <  to_date ('06-04-2010','dd-mm-yyyy') -- to_date('15-01-2007','dd-mm-yyyy')
and      lh.user_id      = substr (subs.subscriber_no, -10)
and     lh.logon_time     >= subs.d1     -- New condition added
and     lh.logon_time     <= subs.d2     -- New condition added
;

Please find DDL and data relevant to these results. There are millions of records of Subscriber & logon_histories_r table, I am given appropriate providing a subscriber_id.

That's smart, don't not post each row of the table: looks like you posted just enough to show what the problem is.
Try to do the same thing with the columns. Do not post every single column, just the columns that have something to do with the problem.

Having trouble selecting from a table function

Need a function to return an array in the following format:

6                      26-NOV-09  16-DEC-09 
7                      29-JAN-09  16-DEC-09

The following error after the selection of a function that returns the table:

select * from table(get_cwsr_ranges)

Error from the 1 in the command line:

Remove the implicit conversion using explicit TO_DATE... you should always do :)

Based on query, I need the values in table C as mentioned below.
Table C (Table of Destination) (necessary output query must also be as below)

The State value

PA 8
DC 1

My query is

INSERT INTO C(STATE,VALUE)
SELECT A.STATE, SUM ($) /SUM (UNITS)
OF A, B
WHERE PAYMENT = "SINGLE".
AND A.STATE = B.STATE
GROUP OF A.STATE, B.STATE

But the output I get is

PA 8
DC 2

Essentially to DC, I should get 1, i.e., for payment only $ DC is 20 and divided by 20 DC must be 1.
Let me know where I'm missing.
Hello

It will work you need to add units in the group by clause
```
SELECT a.state, SUM (dollars) / units
FROM a, (SELECT state, SUM (units) units
         FROM b
         GROUP BY state) sub
WHERE payment = 'SINGLE' AND a.state = sub.state
GROUP BY a.state, units;
```

(1) I used row_number to retrieve the columns, for which the data are intended
(2) I used the PIVOT to convert data into columns.

Re: How to migrate two tables

Creating records from two Tables at the same time...
I would be very grateful if someone could help with the following query.

I have two Tables, Tbl1 and Tbl2. Tbl1 has the following columns: -.

Tbl1_Unique_ID, Description

Tbl1_Unique_ID is of type ' * number *' and ' * PK * ', Description is of type' * Varchar2 *'.

Tbl2 has the following columns: -.

Tbl2_Unique_ID, Description, Tbl1_Unique_ID

Tbl2_Unique_ID is of type ' * number *' and is the ' * PK * ', Description is of type' * Varchar2 *' and Tbl1_Unique_ID is of type ' * number *', is a ' * foreign key *' and is the ' * primary key *' from Tbl1.

While I can create a page to display and create folders in Tbl1, I'm not course coding required to view and create records Tbl1 and Tbl2 simultaneously, as well as regarding the two together at the same time.

I know that it involves one ' * INSERT *' statement, but I have problems the correct SQL query.

Can anyone provide any assistance will be appreciated.
Have you tried to create a form master / detail page? Because it seems that is what you need...

Select from another table, when the query returns no result
Hello

I have a question where I'm supposed to retrieve the address of an account id-based billing. However, the table of billing may not have an address. There is a table of addresses that always has an address for an account. If the billing address exists, it should be used, so I can't use the address table. Is it possible in a select statement to query to the billing address and if it does not exist, use the address table.

SELECT * FROM accounts a, b billings WHERE a.accountid = b.accountid

Any help will be greatly appreciated.

Thank you.

I think you need to explain more clearly if

-you only have a couple of "billing" columns which is empty and in this case, you want to use the columns from the table 'accounts '.

- or you have a join with another table that doesn't return data, for example a foreign key "address_id" "billing" is zero and therefore the join to other tables 'address' will return all the data

In the first case, you have already been provided with some examples here, how to use NVL or similar functions to achieve, even if the first post first evaluates the information of 'accounts' and if it is white using information from "billing". According to your description you need the other way around. The second post a subquery recursive useless in my opinion.

In the latter case, you should probably use an "outer" join so that the data in your table "bills" are returned, even if the join to another table is not at all the lines.
```
SELECT
NVL(AD1.ADDRESS_ATTR1, AD2.ADDRESS_ATTR1) as ADDRESS_ATTR1,
NVL(AD1.ADDRESS_ATTR2, AD2.ADDRESS_ATTR2) as ADDRESS_ATTR2,
NVL(AD1.ADDRESS_STREET, AD2.ADDRESS_STREET) as ADDRESS_STREET,
...
FROM accounts a
INNER JOIN billings b
ON a.accountid = b.accountid
LEFT OUTER JOIN address ad1
ON b.address_id = ad1.address_id
INNER JOIN address ad2
ON a.address_id = ad2.address_id;
```
In this way you pick up the address stored in the "invoices" table, if it existed, otherwise you pick up the address assigned to the "accounts" table I used an inner for the second address join join because you said that the account always has an assigned address.
