What are the main differences between an Equi Join and an Inner Join ?

CREATE TABLE MTCH_TBL
(
S_PAID VARCHAR2(100),
S_SEC NUMBER,
H_PAID VARCHAR2(100),
H_SEC NUMBER
);
[code]....
My requirement is to match the records in MTCH_TBL and HIST_TBL on the basis of joining S_SEC(MTCH_TBL) with SEC_ALIAS(HIST_TBL) and INSTANCE (HIST_TBL) as 100 and choosing the record with max EFF_DATE from HIST_TBL.
I have come up with a query as:
select a.h_sec, a.s_paid, a.h_paid
FROM MTCH_TBL a,
HIST_TBL b
where a.S_SEC=b.sec_alias(+)
and b.instance(+)=100
and b.EFF_DATE =
[code]...
join using the EFF_DATE field also and get the expected results.My results are appearing as BLANK. However I need to produce the results as stated below:
Now, i need the results as:
H_SEC= 526
S_PAID= Q00
H_PAID = Q00
I am trying to develop an application of cars. The car have marques example :
TOYOTA,HUNDAI,CHEVROLET
each mark have families example: TOYOTA have Hilux, yaris corola, CHEVROLET have opra,...etc. Each family have a lot of models example: hilux have h2kn-clim,.. etc. And finally there are some options witch are generally in all cars example Radio-k7,air-conditioner ... etc.
option 1..n-----------------1..n model the relation call(opt_mod)
i did develop the block of marques (master) and the block of families (detail) in a form 1. i did develop the bock of models(master) in form 2 and the is no problem. but i want to add to form 2 the block of (opt_mod) but the user did tell me that he want to to see all options with check boxes .
As a solution of this problem i want to build a block on LEFT JOIN between table :option and table :opt_mod
This is my working query in ms access...
UPDATE Caxnode AS A INNER JOIN Caxnode AS B ON A.node_alias = B.node_alias SET A.partition_Type = 'LDOM', A.node_mode = 'LOGICAL', A.host_id = b.host_id, A.num_of_proc = b.num_of_proc WHERE (((A.node_mode)='virtual' Or (A.node_mode)='regular') AND ((B.partition_Type)='LDOM'));
This doesn't work in oracle, I googled and read that update doesnt work with inner join in oracle..translate this query to work on oracle?
I'm trying to create a relation from child block to the master block that I've created . Foreighn key is there from child to parent table.The error I get is below:
FRM-15004: Error while parsing join condition
The join condition is correct, but I'm still clueless as to what it could be.Is it a form bug?
i want to update record that is fetched based on join condition on form
1. made a block manually :::: EMPSAL
2. Query DATA SOURCE NAME :::: EMP a, Sal b
3. Where Clause :::: a.empid = b.empid
4. DML DATA Target Type :::: Table
5. DML DATA Target Name :::: EMP a, Sal b
6. All Columns are marked a.empid, a.empname, b.sal, b.date etc
It does not allow me to update record.
I receive a "FRM-15004 Error while parsing join condition" when attempting to create a relation between block1 (parent table) and block2 (child table). If I do a simple straight join the statement is accepted but if I use a Decode then it results in an error. How to successfully use a decode or a nvl in a join statement of a relation?
Results in Error:
block1.case_id = block2.case_id and
decode(block1.employee_id, null, block1.entity_id, block1.employee_id) =
decode(block2.employee_id, null, block2.entity_id, block2.employee_id)
This join is accepted but I would like to use a decode since a record can have either a employee_id or entity_id, not both
block1.case_id = block2.case_id and
block1.employee_id = block2.employee_id and
block1.entity_id = block2.entity_id
When executing a SELECT with JOIN in oracle error as I am having the title. If I change the JOIN to where the procedure works normally. When installing my application, it works normally for a day or two, then it only shows the end of communication error. What I do is select the following:

Lets say I have three tables t1 and t2 and t3.
SELECT * FROM T1;
Id
____
1
2
3
4
SELECT * FROM T2;
Id
____
1
SELECT * FROM T3;
Id
____
1
Now when data exists in T2 and T3, I want to return only the records in T1 that match the records in T2 and T3 which is basically a normal join
select t1.id from t1, t2,t3 where t1.id = t2.id and t1.id = t3.id
However when there are no records in T2 or T3, I want to return all records in T1 i.e 1,2,3,4
One way of doing that is using the not exists clause
select * from t1 where not exists ( select null from t2 where t2.Id != t1.id) and not exists ( select null from t3 where t1.Id != t3.id)
Is there a better way of doing this in sql ?

I need to join 2 tables based on first match.. I cldnot use distinct on the result, as distinct work with entire row..
I cant use group by as well, since for group by hv to select all the columns which we need to display
I have 2 tables SEC_MASTER_HISTA and SEC_MASTER_HISTB.
Now, I need to compare the data of the two tables column-wise.
Ideally the 2 tables should have the same security_alias values but in my case they do not as the two tables belong to 2 diff client models. There is however a main SECURITY_MASTERA and SECURITY_MASTERB tables which have the security_alias recorded and a primary_asset_id column value which can act as a link between SEC_MASTER_HISTA and SEC_MASTER_HISTB. But, I have not been able to figure out the exact query which will be ideal.
Attached are the table structures and the data it contains.
Note: I need to compare the Coupon and Freq column values of SEC_MASTER_HISTA and SEC_MASTER_HISTB.
The existing format of the records are

Throught this query, I get a extra record with null value in the Sub_name and Sub_Cno.update this query using a self join.
im trying to update a column in the employee table with the value "YES". Im getting an error message saying im missing a SET statement from this code below:
update e
SET e.review='YES'
from employee
inner join rentals r
on e.employee_id=r.employee_id

drop table dev10 purge

select rownum c1, sys.dbms_random.string('U', 6) c2, trunc(sys.dbms_random.value(1, 7)) c3
from dual connect by rownum < 8

[Code]...
Now, Let us assume that, the record is
AAAAAA BBBBBB CCCCCC
DDDDDD EEEEEE FFFFFF
...
..
.
Now, we want dev12.c2 is 'FFFFFF' if dev11.c2 is 'BBBBBB', if we want to get this:
AAAAAA BBBBBB FFFFFF
DDDDDD EEEEEE FFFFFF
...
..
.
We can make this for SqlServer by coding:
UPDATE dev10
SET c3 = dev12.c1 FROM dev10 INNER JOIN dev11 ON dev11.c3 = dev10.c1 CROSS JOIN dev12
WHERE (dev11.c2 LIKE 'BBBBBB')
AND (dev12.c2 LIKE 'FFFFFF')

but, Oracle, what should we do new?
This is my working query in ms access...

This doesn't work in oracle, I googled and read that update doesnt work with inner join in oracle..
translate this query to work on oracle?
Equi join (Inner join)
It is the simplest join or inner. An equijoin combines rows that have equivalent values for the specified columns.
SQL> select * from x;

I mean see two different outputs.first output records twice displayed ... Yes i agree that is Inner join.second output records not displayed twice... common records only displayed once ,in x and y.
I think should n't use a table name or alias when referencing columns used in a USING clause... am i right ????
I want to know both are inner joins .how Oracle is determined both outputs ?
what is Hash join?how it is different from inner join?what is the sign used for inner join?(eg: like the (+) sign used for outer join)?
View 1 Replies View RelatedIf i have a table T1 and a table T2. Table T1 is having 100 rows and table T2 is having 20 rows. When performing a Hash join ,which table should be used to make the hash table ,the larger one or the smaller one and why ?IF the data set is too small for considerations then please conser table T1 with 10 million of rows and table T2 with 1 million of rows.

If I want to join two table together . I want to search the number of record in IMEI that have N_SIM_STATE =1 in RCA_SMART_CARD . The MSISDN in IMEI is equal to C_SIM_MSISDN in RCA_SMART_CARD .
I have a piece of code that joined the same table onto itself twice in order to get the previous, current and future year's into columns in the same output.
Up until recently this has been working fine but the most recent data has just been uploaded into the table and now it comes up with an error.
On the second (left outer) join it now says that the column is ambiguously defined (ORA-00918). It doesn't matter which order the joins are in it is always the second join that the error pops up on.
I have 2 sql's statement below, and just wondering if their is difference between the two sql's.
FIELDS data type:
--------------------
a.field is DATE
b.field is also a DATE
SQL1:
-------
SELECT a.*, b.*
FROM table a
INNER JOIN table b
ON a.field = b.field
WHERE a.field between b.field AND b.field + 2
;
SQL2:
-------
SELECT a.*, b.*
FROM table a
INNER JOIN table b
ON a.field between b.field AND b.field + 2
;
OR
SELECT a.*, b.*
FROM table a
INNER JOIN table b
ON a.field >= b.field AND
a.field <= (b.field + 2)
;
which ever is correct between the two sql.
QUESTION: would be the two sql's generate same result set.

My questions are
** I think why NATURAL JOIN key word throws error.
** Second query succeed. i think it is inner join. am i right ??????
** If i execute query without alias why oracle throws error ???? Example shown below
