SQL & PL/SQL :: How To Join Two Where
Oct 15, 2012
I want to create a query with only the junction of these two queries:
- select id_utilizador,nbeneficiario,nome from adm_utilizadores a WHERE exists ( select 1 from adm_util_grupos b where
a.id_utilizador = b.id_utilizador and b.id_grupo = '1') ;
- SELECT b.*,rownum as row_num FROM ADM_UTILIZADORES b ORDER BY $sidx $sord
WHERE row_num BETWEEN $start AND $end";
Virtually want id_utilizador, nome, and nbeneficiario, I can get the first query, ordered me returning the first 10.

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 am new to 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.

drop table dev10 purge

drop table dev11 purge
/
drop table dev12 purge
/
create table dev10 as
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...
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?

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;
NAME EMAIL EMPID
Sam email@removed 1060
Rose email@removed 1061
[code]....
don't consider above mentioned queries I got valuable outputs.
NAMEEMAIL EMPID NAME EMAIL EMPID
samemail@removed 1060 sam email@removed 1060
roseemail@removed 1061 rose email@removed 1061
sonaemail@removed 1062 sona email@removed 1062
Inner join shows matches only when they exist in both tables.so , i got records 1060,1061,1062
// Referencing columns used in a USING clause.
SQL> select x.name,x.email,x.empid from x
2 inner join y
3 using (empid);
select x.name,x.email,x.empid from x
*
ERROR at line 1:
ORA-25154: column part of USING clause cannot have qualifier
so query rewritten as
SQL> select x.name,x.email,empid from x
2 inner join y
3 using (empid);
NAME EMAIL EMPID
--------------- --------------- ----------
sam email@removed 1060
rose email@removed 1061
chris email@removed 1062
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 ?

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.

I am creating a query where I am trying to take phone call lengths and put them into buckets of length ranges 0:00 - 0:59, 1:00 - 1:59 etc. Even if there are no calls in the call table I need to return the range with a zero (hence the left join and nvl). When I do this the left join acts like an equal join, I suspect there is some reason left joins only work if there is an equal condition in the join (instead of >= and < that I use, or similarly I could use BETWEEN). I also have a question about performance (below).
The create table script for the lookup is like this:
CREATE TABLE DURATION_RANGES
(
RANGE_TEXT varchar2(20),
RANGE_LBOUND decimal(22),
RANGE_UBOUND decimal(22)
)
Sample inserts are:
INSERT INTO DURATION_RANGES (RANGE_TEXT,RANGE_LBOUND,RANGE_UBOUND) VALUES ('00:00 - 00:59',0,59);
INSERT INTO DURATION_RANGES (RANGE_TEXT,RANGE_LBOUND,RANGE_UBOUND) VALUES ('01:00 - 01:59',60,119);
etc.
The query is:
select
r.range_text as duration_range,
nvl(count(*),0) as calls,
nvl(SUM(call_duration),0) as total_duration
from
[code]...
As I say, it is not returning all ranges in the duration_ranges table, so acting like an inner join. I realize one solution would be to populate duration ranges with every value possible (instead of ranges) so join is an equal join, but that would make the duration_range table larger.
My questions:
1. Is it possible to get the left join to work with the duration range values as they currently are?
2. Even if 1 is possible, would it be better performance to have exact values (but a larger lookup table) and do an equals join instead of >=, < or BETWEEN? Performance now is not bad.
What I mean is (with only one time value and not lbound and ubound:
INSERT INTO DURATION_RANGES (RANGE_TEXT,RANGE_LBOUND,RANGE_UBOUND) VALUES ('00:00 - 00:59',0);
INSERT INTO DURATION_RANGES (RANGE_TEXT,RANGE_LBOUND,RANGE_UBOUND) VALUES ('00:00 - 00:59',1);
INSERT INTO DURATION_RANGES (RANGE_TEXT,RANGE_LBOUND,RANGE_UBOUND) VALUES ('00:00 - 00:59',2);

I have an attendance table in which we have empno, time_in, time_out..etc.
I want to create a matrix report that should shows all dates of any specific required month in columns and present empno in rows and time_in in cells.
I did it with using a temporary table by filling all the required dates and outer join with attendance table, it works fine, but it takes so long, is there any other better fast way to do it?

I have this ORACLE SQL and just about understand join syntax in the From clause, i.e.
SELECT *
FROM TABLE 1 LEFT OUTER JOIN TABLE 2
ON TABLE1.FIELD_X = TABLE2.FIELD_X
However, I've inherited the sql below.
SELECT
RELOCATION.START_DATE,
STUDENT.SURNAME,
STUDENT.FORENAME
CURRENT_SCHOOL.BASE_ID
RELOCATIONS.STUD_ID
[code]......
I particularly don't understand this part
' FROM (MYDATABASE.STUDENT STUDENT
LEFT OUTER JOIN MYDATABASE.BASES CURRENT_SCHOOL '
why the table name student is referenced twice?And again for ' MYDATABASE.BASES CURRENT SCHOOL '?
When I put this into SSRS it shows only links between the tables STUDENT, RELCOATIONS and CURRENT_SCHOOL. Bases isn't mentioned in the tables diagram. it is still referred to in the raw SQL.
The above SQL works fine, i just don't understand what it's doing!

Here is what I'm trying to do:
I have three tables:
TABLE1 TABLE2 TABLE3
NCI 1AB OPEN
NCI (NULL) (NULL)
INV (NULL) (NULL)
NCI 2AB REOPEN
What I want to do is to return all of the rows from TABLE1 that are NCI regardless, and if they are NCI, I want to return the corresponding records from TABLE2 and TABLE3.
If TABLE1 has a record of NCI but there are no corresponding records in TABLE2 or TABLE3, then of course the columns for TABLE2 and 3 would be blank.
I can get all of the NCI records from TABLE1 when I LEFT JOIN with TABLE2, but when I try to specify TABLE3 in the FROM statement, only the records that are NCI in TABLE1 AND have data in TABLE2 are returned, not just all records with NCI in TABLE1.
Let me know if I can further clarify.
I know that you do not have access to my tables, but here is an example of my code so that you may understand my quandary further:
SELECT l.sku AS "SKU",
l.loc AS "LOC",
l.qty AS "QTY",
o.ncikey AS "NCI",
r.description AS "NCI DESC",
o.qtyexpected AS "NCI QTY EXP",
o.qtyreceived AS "NCI QTY REC",
o.loc AS "NCI LOC",
o.status

Using Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
Here's a simplified version of the query I am having problems with:
SELECT
assoc.association_id
FROM mentor_initiative mi
LEFT JOIN program assoc_prog ON assoc_prog.program_id = -1
LEFT JOIN mentor_association assoc ON assoc.mentor_initiative_id = mi.mentor_initiative_id AND
NVL(assoc_prog.program_id, -1) = NVL(assoc.program_id, -1)
Note that there is no program with program id -1. So the assoc_prog left join will come up with nothing. I was thinking that since assoc_prog.program_id will be null, the second assoc left join would pick the row where assoc.program_id is null. However, the second left join doesn't join to any row.
In this query, it does join to an assoc row (I changed assoc_prog.program_id to NULL)
SELECT
assoc.association_id
FROM mentor_initiative mi
LEFT JOIN program assoc_prog ON assoc_prog.program_id = -1
LEFT JOIN mentor_association assoc ON assoc.mentor_initiative_id = mi.mentor_initiative_id AND NVL(NULL, -1) = NVL(assoc.program_id, -1)
I was thinking it would join to an assoc row in the first query though. How can I change the first query to have the desired effect of left joining to a row where assoc.program_id is null if assoc_prog.program_id is null?

I have two tables A and B
Table A
bill_id number,
bill_line_id number,
discountnumber,
month varchar2(12),
year varchar2(4)
Table B
bill_id number,
bill_line_id number,
total_amt number,
customer_idnumber,
sales_repvarchar2(25),
sales_begindate,
sales_enddate
For all the records in table B I am trying to get discount information from table A. Each bill_id has one or many billing_line ids.It is not mandatory that all the bill_line_id from table B should be present in table A.in other words: a.bill_id can be 100 and a.bill_line_id = 456 but in table B, for b.bill_id =100 there can be b.bill_line_id = 123 and bill_line_id = 456.
I am joining the 2 tables based on bill_id, bill_line_id, and the start and end date.I am not sure how the outer join is done...Basically for every bill_id i need all bill_line id from table A.I am not sure how to *outer join on only one column*. When i tried it did not fetch all the rows from A.
select *
from table B left outer join table A on
a.bill_line_id = b.bill_line_id
and a.month = TRIM (TO_CHAR (b.sale_begin, 'Month'))
and a.year = extract(year from b.sale_begin)
where a.bill_id = b.bill_id
This is what I need: for every bill_line_id in table B i need discount information from table A if that bill_line_id is not in table A, the discount can be null. But, the bill_line_id in A and B should be for the same bill_id a.bill_id = b.bill_id and the outer join ......
