Sql to JOIN 3 tables
I need some help on my sql to join 3 tables.
I am close, but my results come out to be a multiple of what im supposed to get.
I am trying to retrieve a sum from table 2 and table 3.
there are 4 records in table2 and 3 records in table3
the results SHOULD be 3 and 20
but i get 12/60
which is a number i shoudl get times the #records of the oppposite table.
i have moved my code in different arrangements to see if that is the issue, but it doesnt seem to matter. i still get the result of a multiple.
Heres my code so far:
SELECT sum(table3.field) AS sumtable3, sum(table3.field) AS sumtable2
FROM table1
LEFT JOIN table2 ON table1.id=table2.id
LEFT JOIN table3 ON table2.id=table3.id
GROUP BY table1.id
ORDER BY table1.id
Please provide sample data for all 3 tables.

Joining 2 tables in oracle database using SQL
I want to join 2 tables together before executing a statement.
problem is one is a table of users, who have userID's
and the othet table is a table of events that are owned by a userID, ie can have many events by same userID.
i want to retrieve forename and lastname from the users table, nd the event details from the event table, and put a name against each event rather than a userID, how can i do this?
note i want to extract EVERY SINGLE EVENT, and get the name of the user it is owned by via the userID
heres a example of a row
Table Users
| UserID | Forename | Surname |
| Y244850 | Jimmy | Conner |
| Y256738 | Mikey | Reeves |
Table Events
| UserID | Date | Type | Location |
| Y244850 | 07-Jan-01 | Holiday | Ibiza |
| Y244850 | 15-Dec-01 | Holiday | Jamaica |
------------------------------------------------Well just exchange user_id with u.user_ud or l.user_id:
SQL> SELECT forename, surname, TO_CHAR(id) id,
TO_CHAR(start_date) start_date, TO_CHAR(end_date)
end_date, type, u.user_id, location FROM leave_details l,
user_details u WHERE l.user_id = u.user_id;
When you just say select user_id, the database doesn't know wich user_id to use. The one in details or in users...
(Even though you and me know its the same)
So just be spesific and choose one.

This is a newbie question! I would like to join two tables. Table_1 contains xml stylesheets:
id stylesheet doc
1 <xml stylesheet doc A>
2 <xml stylesheet doc B>
And Table_2 contains the XML documents that the stylesheets will transform:
id XML doc
1 <XML document 1>
1 <XML document 2>
1 <XML document 3>
2 <XML document 4>
2 <XML document 5>
I would like <xml stylesheet doc A> to transform only XML doc that have an id of 1, so I tried this sql statement:
select a.stylesheet_doc ,b.xml_doc from Table_1 a, Table_2 b where a.id=b.id and a.id=1;
This statement returns the rows I want (stylesheet doc with id equals 1, and xml_doc with id equals 1), but it pairs each xml document with a style sheet.
stylesheet doc A <XML document 1>
stylesheet doc A <XML document 2>
stylesheet doc A <XML document 3>
My question is, is there a way to have a result that looks like this?
stylesheet doc A
<XML document 1>
<XML document 2>
<XML document 3>
That is, is there a way in sql to get rid of duplicate stylesheet doc A?
I have tried group by and rollup and xmlagg.
Thank you very, very much for your help.
JimHi, Jim,
Welcome to the forum!
You just want to display the XML, not actually transform it, right?
GROUP BY ROLLUP should work, but I find it easier with GROUP BY GROUPING SETS. Here's an example from tables in the scott schema:
SELECT CASE
WHEN GROUPING (ename) = 1
THEN d.dname
END AS dname
, e.ename
FROM scott.dept d
JOIN scott.emp e ON d.deptno = e.deptno
GROUP BY GROUPING SETS ( (d.dname, e.ename)
, (d.dname)
ORDER BY d.dname
, ename NULLS FIRST
;Output:
DNAME ENAME
ACCOUNTING
CLARK
KING
MILLER
RESEARCH
ADAMS
FORD
JONES
SCOTT
SMITH
SALES
ALLEN
BLAKE
JAMES
MARTIN
TURNER

Joining two tables using PL/SQL
here i am trying to join two tables can any one tell me what is wrong with this syntex
CREATE OR REPLACE PROCEDURE test IS
CURSOR c1 IS SELECT seq,fname,lname from t1;
CURSOR c2 IS SELECT seq1,q,a from t2;
userjob number;
BEGIN
OPEN c1;
insert into t3 values(c1.seq,c1.fname,c1.lname);
FETCH c1.seq INTO userjob;
FOR c1rec IN c2 LOOP
IF (c1rec.seq=c1.seq and c1rec.q1='why') THEN
insert into t3 values(c1rec.q1,c1rec.a1);
elsif (c1rec.seq=c1.seq and c1rec.q1='what') then
insert into t3 values(c1rec.q2,c1rec.a2);
elsif (c1rec.seq=c1.seq and c1rec.q1='when') then
insert into t3 values(c1rec.q3,c1rec.a3);
elsif (c1rec.seq=c1.seq and c1rec.q1='where') then
insert into t3 values(c1rec.q4,c1rec.a4);
END IF;
END LOOP;
END;
/You should always fetch a cursor before using it's values. All columns in the select should be fetched into variables or a record-variable. You can't refer to the cursor-columns values with c1.seq etc.
r1 c1%rowtype;
l_found boolean;
BEGIN
OPEN c1;
FETCH c1 INTO r1;
insert into t3 values(r1.seq,r1.fname,r1.lname);
l_found := c1%found;
close c1;
if l_found
then
It is also better to close the cursor and check if the select resulted in a row. With this code you will only retrieve one row even if the select will result in multiple rows.
But I agree with all the others that this can probably be done more efficiently with one SQL statement. -
hi morning,
my problem also haven find out the solution,can help me solve.
I got one part of register student to exam,during that part is like that.
Student Code:________(table3)
Exam Code:_________(table 3)

Exam Name:_________(table 2)
I can write code call table 3 but when three table join together in part 3,got problem is come out alry....The problem is inside the Student Name & Exam Name.When i use the button for NEXTRECORD to check record,cannot call the student Name & exam Name.
Thank for help. Because i use sql code to call table 3 to check table1 and table 2 detail ,then retrive that data.

SQL Join Three Tables DW MX2004 ASP
I'm trying to display records using three tables joined as
shown in the SQL code below. I'm getting "no data" message when I
test the result page from the search form. I'm using the advanced
Dreamweaver form to enter the SQL commands. I have never used this
feature of Dreamweaver before and I'm not sure if the code below
follows the way DW MX will understand what I'm trying to do. Below
is the code based on Standard SQL....not sure if DW compatible...
This is what I typed in the SQL box:
SELECT
ResourceSkillMapping.resourceSkillMapID,ResourceSkillMapping.skillID,
ResourceSkillMapping.competenceLevel,skill.skillname,resource.resourceName,resource.resour ceLoginId
FROM ResourceSkillMapping INNER JOIN Skill ON
ResourceSkillMapping.skillID = Skill.skillID
INNER JOIN Resource ON
ResourceSkillMapping.resourceSkillMapID =
Resource.resourceSkillMapID
WHERE (Skill.skillName = '%Skill_asp%') AND
(Resource.resourceLoginID = '%Agent_asp%')
AND (Resource.active = 1)
These is typed in the variables box:
Variable Default Runtime
Skill_asp 1 Request.QueryString("skillname")
Agent_asp 1 Request.QueryString("resourceLoginID")
I'm using asp and the "Get" url parameters in the search form
calling the result recordset in DW. I'm connecting to a SQL 2000
server. Is this notation DW correct? Am I joining the tables
correctly. The tables are ResourceSkillMapping, Skill and Resource.
All I need is to be able to search by ResourceLoginID and by
skillName on all active records (active=1). The plan is to be able
to click on a result record and go to a detail page to update the
"CompetencyLevel" field in the resourceSkillMapping table using the
update behavior in DW.
Please help as this project is due this Tue and have been
trying every posibility I could think so far....I have read all the
DW help facilities many pages on this and still keep getting the
"no data" message
Thank you,
Carlos
[email protected]>> WHERE (Skill.skillName = '%Skill_asp%') AND

>>'%Agent_asp%')
I would say that this is where your problem is. Change it to:
WHERE (Skill.skillName LIKE '%Skill_asp%') AND
(Resource.resourceLoginID
LIKE
'%Agent_asp%')
and your query should work, unless of course you are actually
searching for
2 strings that read %Skill_asp% and %Agent_asp% exactly.

Hi there,
I have two problems...first being:
We are trying to run a sub-query within a WHERE/AND clause. I am not sure on the correct syntax on how to run the sub-query as denoted in the code below. Secondly I am trying to join two tables with a common column name (ie: CIPIDI_NR). Considering I cant fix the first problem I cant test out the sub-query. So any help on either would be grateful. Cheers

Need help to join two tables using three joins, one of which is a (between) date range.
I am trying to develop a query in MS Access 2010 to join two tables using three joins, one of which is a (between) date range. The tables are contained in Access. The reason
the tables are contained in access because they are imported from different ODBC warehouses and the data is formatted for uniformity. I believe this cannot be developed using MS Visual Query Designer. I think writing a query in SQL would be suiting this project.
ABCPART links to XYZPART. ABCSERIAL links to XYZSERIAL. ABCDATE links to (between) XYZDATE1 and ZYZDATE2.

on this computer. There are no "Null" fields in either of the tables.
This table has many orders (MSORDER) that need to match one order (GLORDER) in GLORDR. This is based on MSPART joined to GLPART, MSSERIAL joined to GLSERIAL, and MSOPNDATE joined if it falls between GLSTARTDATE and GLENDDATE.

Joining 18 tables -- one at a time or in two stages ?? best one..??
I have to join 18 tables,.. Is it best to join all 18 in a single shot or to go with
multi stages-- 9 tables in one stage and after that anotther 9 tables..
Please anyone give me a good suggestion on this with some reason...
Thanks in advanceIf you can look at your query and recognise that it is trying to collect (say) two small result sets and then join the result sets, then it is actually a good idea to express the query in that fashion to Oracle.
Take for example a query that sums last week's profits for a supermarket by department using a 9 table query in about 2 minutes. A similar query reports the previous week's profits with a marginally different query in about two minutes. You write the two queries as inline views and join them to report the percentage change in profit by department - and the query takes 4 hours because Oracle has used "complex view merging" to turn your two 9-table queries into a single 18-table query.
In this case, a workaround is to use the /*+ no_merge */ hint. In outline, something like:
select {columns}
from
select /*+ no_merge */
dept_no,
etc.
from ...
) lw,
select /*+ no_merge */
dept_no,
etc.
from ...
) pw
where
pw.dept_no = lw.dept_no
;In less obvious cases you may still be able to find that you can break up a big query into a few smaller, logical sections, and use this technique to generate and join what are, in effect, intermediate results.
An alternative to the /*+ no_merge */ hint is to use subquery factoring to the same end. There's a more complex example of the method here: http://jonathanlewis.wordpress.com/2007/07/01/internet-sql/
In either case, avoid turning your 18-table query into 18 separate pieces and sticking them back together - it may make the optimizer do some very silly things. Karen Morton mentions an example of this on her blog: http://karenmorton.blogspot.com/2008/06/dont-do-work-you-dont-have-to-do.html

Using functions in select statement(joining 5 tables) taking long time in Oracle
Hi,
I have created a query in oracle which joins 5 tables and uses two functions(function names are 'ca_concat' and 'ca_concat_noseq').
Query takes approximately 40 secs to execute around 12000 records. If I remove the functions from query it excutes within a second..
Note : I have used the oracle SQL Developer for testing the query.
It would be appriciated if anybody helps me to improve the perfomance of the query.
Below are the querie with and without functions:
1. Query with functions:

How do you join two tables from different Oracle schemas using a subquery
I am trying to join two tables from different Oracle schemas using a subquery. I can extract data from each of the tables without a problem. However, when I combine the select statements using a subquery I get the Oracle error *'ORA-00936: missing expression'*. Since each SELECT statement executes on its own without error I don't understand what is missing. The result set I am trying to get is to match up the LINE_ID from PDTABLE_12_1 in schema DD_12809 with the MAT_DESCRIPTION from table PDTABLE_201 in schema RA_12809.
The query is as follows:
sql = "SELECT [DD_12809].[PDTABLE_12_1].LINE_ID FROM [DD_12809].[PDTABLE_12_1] JOIN " _
+ "(SELECT [RA_12809].[PDTABLE_201].MAT_DESCRIPTION " _
+ "FROM [RA_12809].[PDTABLE_201]) AS FAB " _
+ "ON [DD_12809].[PDTABLE_12_1].PIPING_MATER_CLASS = FAB.PIPING_MATER_CLASS"
The format of the query is copied from a SQL programming manual.
I also tried executing the query using a straight JOIN on the two tables but got the same results. Any insight would be helpful. Thanks!
Edited by: user11338343 on Oct 19, 2009 6:55 AMI believe you are receiving the error because you are trying to JOIN on a column that doesn't exist. For example you are trying to join on FAB.PIPING_MATER_CLASS but that column does not exist in the subquery.
If you want to do a straight join without a subquery you could do the following
SELECT DD_12809.PDTABLE_12_1.LINE_ID
, FAB.MAT_DESCRIPTION
FROM DD_12809.PDTABLE_12_1
JOIN RA_12809.PDTABLE_201 AS FAB ON DD_12809.PDTABLE_12_1.PIPING_MATER_CLASS = FAB.PIPING_MATER_CLASS HTH!
