Join the tables in the responses

I would like to know if it is possible to join the tables together as below in the answers?

Select a.Field1, b.Field1
FROM tableA an outer join left tableA b on
a.Field1 = b.Field

If you want to make an INNER JOIN, and then type INNER JOIN instead of LEFT INNER JOIN.

If you want to left outer join and LEFT OUTER JOIN instead of INTERNAL LEFT JOIN type.

Nothing asked as a left inner join. That is why it gives error + [nQSError: 27002] near +.

Thank you

How to join two tables if you transpose the rows, columns and rows in one of the table

Hi guys,.

can someone help me please in the write request

I have two tables

Agents and Agent phones but in the agent phones table for the id of an agent it displays 4 rows because one of the column there types of different phones (office, mobile, home, fax)

So instead of display 4 rows, I used max(case...) to convert rows to columns

now how to reach it with another table

Requirement:

Database: 11.2.0.2.0

create the table AGENT_PHONE

(

agent_id NUMBER (20) not null,

agent_type_code VARCHAR2 (10) not null,

agent_type_prefix VARCHAR2 (10) not null,

Phone_Number VARCHAR2 (16) not null,

phone_type_code VARCHAR2 (10) not null

)

CREATE TABLEAGENTS

(

agent_id NUMBER (20) not null,

agent_type_code VARCHAR2 (10) not null,

agent_type_prefix VARCHAR2 (10) not null,

NAME VARCHAR2 (40) NOT NULL

)

INSERT INTO AGENT_PHONE(AGENT_ID,AGENT_TYPE_CODE,AGENT_TYPE_PREFIX,PHONE_NUMBER,PHONE_TYPE_CODE)

VALUES (29709, ARE ', 'OFFICE', '4805551436', 'CELL');

INSERT INTO AGENT_PHONE(AGENT_ID,AGENT_TYPE_CODE,AGENT_TYPE_PREFIX,PHONE_NUMBER,PHONE_TYPE_CODE)

VALUES (29709, ARE ', 'OFFICE', '1111111111', 'PHONE');

INSERT INTO AGENT_PHONE(AGENT_ID,AGENT_TYPE_CODE,AGENT_TYPE_PREFIX,PHONE_NUMBER,PHONE_TYPE_CODE)

VALUES (29709, ARE ', 'OFFICE', '2223334444',' OFF');

INSERT INTO AGENT_PHONE(AGENT_ID,AGENT_TYPE_CODE,AGENT_TYPE_PREFIX,PHONE_NUMBER,PHONE_TYPE_CODE)

VALUES (29709, ARE ', 'OFFICE', '5556667788', 'FAX');

INSERT INTO VALUES AGENTS

(29709, ARE ', 'OFFICE', 'FLY');

INSERT INTO VALUES AGENTS

(1234, ARE ', 'OFFICE', 'MIKE');

SELECT * FROM AGENT_PHONES

AGENT_ID

AGENT_TYPE_CODE

AGENT_TYPE_PREFIX

PHONE_NUMBER

PHONE_TYPE_CODE

---------------------------------------------------------------------------------------------

29709	RE	OFFICE	4805551436	CELL
29709	RE	OFFICE	1111111111	PHONE
29709	RE	OFFICE	2223334444	OFF
29709	RE	OFFICE	5556667788	FAX

SELECT * AGENTS

AGENT_ID

AGENT_TYPE_CODE

AGENT_TYPE_PREFIX

NAME

29709

OFFICE

ROB

1234

OFFICE

MIKE

This is so the data we have in both table

Now, I transposed rows to columns in the table of agent phones so I used the following query

SELECT AP. AGENT_ID,. AGENT_TYPE_CODE,. AGENT_TYPE_PREFIX.

MAX (CASE WHEN AP. PHONE_TYPE_CODE = 'CELL' THEN AP. PHONE_NUMBER END) AS CELL.

MAX (CASE WHEN AP. PHONE_TYPE_CODE = 'OFF' THEN AP PHONE_NUMBER END) AS TURNED OFF.

MAX (CASE WHEN AP. PHONE_TYPE_CODE = 'FAX' THEN AP. PHONE_NUMBER END) LIKE FAX,.

MAX (CASE WHEN PHONE_TYPE_CODE = 'PHONE'. THEN AP PHONE_NUMBER END) AS PHONE

AGENT_PHONE AP

WHERE AP. AGENT_ID = 29709

GROUP OF AP. AGENT_ID, AP. AGENT_TYPE_CODE, AP. AGENT_TYPE_PREFIX.

	AGENT_ID	AGENT_TYPE_CODE	AGENT_TYPE_PREFIX	CELL	OFF	FAX	PHONE
1	29709	RE	OFFICE	4805551436	2223334444	5556667788	1111111111

My question is how this to join the agents table so that my output should be like this...

I want to display all the results in the table of the Agent, even if they are not in the table of agent phones. As you can see there are other agent id 1234 is also populated

AGENT_ID

AGENT_TYPE_CODE

AGENT_TYPE_PREFIX

NAME

AGENT_ID

AGENT_TYPE_CODE

AGENT_TYPE_PREFIX

CELL

PHONE

OFF

FAX

Currently, I run this query and I get the output as below

You can rotate your phone number of agent in columns

Select *.

of AGENT_PHONE

pivot)

min (PHONE_NUMBER)

for PHONE_TYPE_CODE in ('CELL' as a 'CELL', 'PHONE' like 'PHONE', 'OFF' in the 'OFF', 'FAX' as 'FAX')

)

AGENT_ID	AGENT_TYPE_CODE	AGENT_TYPE_PREFIX	CELL	PHONE	OFF	FAX
29709	RE	OFFICE	4805551436	1111111111	2223334444	5556667788

Then you can join to view inline or CTE

with AGENT_PHONE_PIVOT like)

Select *.

of AGENT_PHONE

pivot)

min (PHONE_NUMBER)

for PHONE_TYPE_CODE in ('CELL' as a 'CELL', 'PHONE' like 'PHONE', 'OFF' in the 'OFF', 'FAX' as 'FAX')

)

SELECT *.

AGENTS HAS

LEFT OUTER JOIN AGENT_PHONE_PIVOT AP

ON A.AGENT_ID = AP. AGENT_ID

AND A.AGENT_TYPE_CODE = AGENT_TYPE_CODE.

AND A.AGENT_TYPE_PREFIX = AGENT_TYPE_PREFIX.

Hi Vincent,.

I think that you have not worked on adf 12.1.3. In adf 12.1.3 you don't have to explicitly create the association. When you create the EO to your table, Association xxxxFkAssoc, will be created by ADF12.1.3 for you automatically. Please try this and do not answer anything... You can also follow the links below.

JOIN the question... Join two tables without omitting lines

I came across a problem that should be an easy fix (I hope), but I'm having a hard time to come up with a solution.

Basically I have two tables, one with the actual amounts with the budget. I have to write a sql statement select that joins these tables together and includes all of their lines. I was able to join the tables by using JOIN, LEFT JOIN and RIGHT JOIN, but it always fails the lines I need.

Below, I have examples of my tables (AMOUNT_TABLE and BUDGET_TABLE). For simplicity, I built the examples to show the same values in the first four columns, with the 5th and 6th columns (SUB_ACCOUNT, AMOUNT, BUDGET) as the only values that are different. My actual tables are not quite that simple, but I don't think it was relavent to this issue.

AMOUNT_TABLE

FISCAL_YEAR	PERIOD	ACCT_UNIT	ACCOUNT	SUB_ACCOUNT	AMOUNT
2013

111111555555000010020131111115555551000100201311111155555520001002013111111555555300010020131111115555554000100

BUDGET_TABLE

FISCAL_YEAR	PERIOD	ACCT_UNIT	ACCOUNT	SUB_ACCOUNT	BUDGET
2013

1111115555553000200201311111155555540002002013111111555555500020020131111115555556000200

Here's what I hope. Note that SUB_ACCOUNTs 0000, 1000, and 2000 show without budget amounts since there is not a corresponding line in the BUDGET_TABLE. And same for SUB_ACCOUNTs 5000 and 6000, they show budgets with no amount because there is not a corresponding line in the AMOUNT_TABLE.

(exit)

FISCAL_YEAR	PERIOD	ACCT_UNIT	ACCOUNT	SUB_ACCOUNT	AMOUNT	BUDGET
2013	1	11111	555555	0000	100	0
2013	1	11111	555555	1000	100	0
2013	1	11111	555555	2000	100	0

2013	1	11111	555555	6000	0	200

If all goes well, my question is clear. Any help on this would be greatly appreciated. Thanks in advance.

So he needs to MERGE between DEPARTMENTS (that has been sorted by index) JOIN and (here's the part confusing...) LOCATIONS including oracle used HASH JOIN (?) to bring the information from and then sort the opinion generated by the system that has been created...?

Is that this HASH JOIN to step 7 only refers to a view that is generated by the system that oracle had to sort and not actually HASH JOIN
between two tables?

Thanks much for you patience

Hello

Perhaps, it helps to understand things better if we walk in the plan.

Plans have a hierarchical structure (which is translated graphically by fingerprints). Operating needs parent all the children completed operations before it can do its job (which is generally combining lines with children in one way or another).

Another point is that joins can have anything like their entries, tables not only. That is a hash join can join an index for an index or a table to an index, or then to join a table results of hash one another and so on and so forth.

With this in mind, we can go back on what is happening here step by step:

The needs of the join by hash (1) (2) and (10) to finish. (10) is a basic operation, since a table scan depends on nothing else, but merge join handset (2) (3) and (5), who both are complex operations (i.e. dependent on one or more children). Specifically, lines (3) from the DEPARTMENTS table using ROWID obtained from a full analysis of the index of DEPT_LOCATION_IX (4), (5) is simply lines join hash (7) and sorted in the order required.

I hope this helps.

Best regards
Nikolai

Hi, I'm new to these forums and I have looked everywhere and cannot find the syntax and examples on how to join the tables 2 and 3 using the ANSI standard, but I need to reach 4. For a traditional join, it would be:

SELECT a.two b.one, b.three, b, a.one, d.seven
Tablea, tableb b, c in tablec, deposited d
WHERE a.one = b.one
AND a.two = c.two
AND c.six = d.six;

Here are the tables:

TableB
one
three
four

TableA
one
two

TableC
two
six

deposited
six
seven
eight

Anyone know how to do this by using an ANSI join or have all of the resources that can guide me in the right direction. I don't know if I wanted to join three tables, it would be:

SELECT a.two b.one, b.three, b, a.one, c.six
FROM tableb b JOIN tablea one WE b.one = a.one JOIN tablec c ON a.two = c.two;

so join a fourth would:

SELECT a.two b.one, b.three, b, a.one, d.seven
FROM tableb b JOIN tablea one WE b.one = a.one JOIN tablec c ON a.two = d JOIN filed c.two ON c.six = d.six;?

Is the above correct or is there another way to do this, use an ANSI join?

Hello

your JOIN looks good,

"FROM tableb b JOIN tablea one WE b.one = a.one JOIN tablec c ON a.two = d JOIN filed c.two ON c.six = d.six" you get a different result set?

Thank you

[Help] Join the query from 3 tables
Hi, I'm new to database. I have a question about joining 3 tables, forgive me for my bad English.

My paintings look like this

Table 1: person (id, firstname, lastname)
Table 2: AssignPersonAddress (id, personid, addressid, type)
Table 3: address (id, phone, street, etc.)

I need AssignPersonAddress table, because in my data structure, a person may have more than 1 address and address type must be registered (for example: private, work)

I want to do a select query to the State any person with his private phone and work phone, like this.
NOBODY | PRIVATE | WORK

Right now my query looks like this
```
select p.name , a1.tel AS Private, a2.tel AS Work
from person p, 
addresse a1 , 
AssignPersonAddress apd1, 
AssignPersonAddress  apd2, 
addresse a2

where p.id  = apd1.person (+)
and apd1.adresse  = a1.id 
and apd1.art = 'Private' 
and p.objectid = apd2.person (+)
and apd2.adresse  = a2.id 
and apd2.art = 'Work'
```
the problem is that I only get the person who has a private address and the job. But what I want is all anyone no matter if the person has only 1 or 2 address.

As you can see I put the left outer join in where condition, but I always get the wrong result.

THX in advance

Danny

Join the table orders from clause
Hi all

Who is the effective way to join the tables in from clause. I have two tables first with 20 lakh records and second containing 10 lakh recods.
```
 
QUERY 1:  SELECT T4.ID,T4.ISO_NAME  FROM T,T4 
WHERE T4.ISO_NAME LIKE '%US%' AND T.ID=T4.ID;

QUERY 2:  SELECT T4.ID,T4.ISO_NAME  FROM T4,T 
WHERE T4.ID=T.ID AND  T4.ISO_NAME LIKE '%US%';

T(ID IS PRIMARY KEY) 
(20 lakh records)

T4 (ID IS PRIMARY KEY ) 
(10 lakh records)
---------------------
ID     ISO_NAME
100  US,UK,IN,BR
101  UK,US,BR,IN
102  BR,UK,US,IN


Note: No index on ISO_NAME .
```
Who is the effective query 1 or 2. Please suggest me if you have an idea to rewrite the query.

Kind regards
Rajasekhar

In practical terms, Alex is right. Sometimes it matter what table is selected first, but does the CBO generally a very good job of deciding what you need to select the first (assuming that your statistics are up to date) but this is the situation you are trying to avoid as much as possible.

If you specify a table main command tables in the clause is not reliable and should be used - but think before using advice and don't do that when necessary.

Which table to select depends firstly on the join method in the execution plan. Nested loops joins perform better by selecting in the smaller table first, make a loop on the largest table. Joins the smaller set hash table in memory first, and then go through the larger table, perform searches in memory. He can't make any difference, what table is read using first the merger joins and sort.

Back to your original question. Using the cost-based optimizer, both queries will probably roll the same because newer versions of Oracle (9i, 10g) often transform queries for efficiency before the execution anyway. According to what do you or do not request should probably run a nested loop or hash join. With a small set of data creaing index and using a search of nested loops will probably be faster to avoid full table scans. the '%' in the LIKE clause leader would ignore an index on the ISO_NAME column in any case if a main column may be used in a composite index. All this is based on the approximation using the information provided; Tuning questions should always be tested to unexpected developments.

Get the response time data VI

Hi guys,.

I am trying to use CD get time response data VI my VI. When I choose the pair of input-output, I can get the response data determined by the digital input to the output value. However, I need more of a pair of response data. I try to use the list of input-output, but there is no output data and response time of the VI with table 1 d of numbers.

My question is how to use the CD get time VI data response with the list of inputs-outputs configuration? Thank you.

Hey, Shapiro,.

I think the problem is you have two 0 items in the above table for you will be out this definition data twice. Let me know if this does not solve the problem for you.
