SQL & PL/SQL :: Join Syntax In From Clause
Jul 21, 2010
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!

I am trying to use the following case statement in my where clause. My problem here is, I get no rows.
tab1.col1 =
case
when (tab1.col1 = 'VAR') and (tab1.col2 is null or tab1.col2 >= tab2.datecol) then
tab1.col1
else
null
end

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?

Use ANSI standard JOIN syntax for example i have this code.
SELECT resv_num, unit_date
FROM p_resv_unit ru, p_pm_unit_night pun
WHERE pun.property_id = in_property_id
AND pun.pm_unit_num = cvUnitNum
AND pun.unit_date BETWEEN start_date AND end_date
AND pun.resv_unit_id = ru.resv_unit_id;
[code]....
and is it a good idea to change it, because both ways it works?

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 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.

CODESQL> select * from em1;
EMPID NAME SALARY
---------- ---------- ----------
1060 sam 4000
1061 rose 3700
1062 sona 4800
SQL> select * from dept;
EMPID NAME DEPT_NAME
---------- ---------- --------------
1060 sam INFO TECH
1061 rose BIO INFO
1063 chris COMP SCI
1064 maya MULTI MEDIA
I am TRYING to get output for on clause( NATURAL JOIN)
CODESQL> select x.empid,x.name,x.salary,y.dept_name from em1 x NATURAL JOIN dept y
2 on x.empid=y.empid;
on x.empid=y.empid
*
ERROR at line 2:
ORA-00933: SQL command not properly ended
[code]...
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
I saw lot of examples like this
SQL> select empid,name,salary,dept_name from em1 natural join dept
2 on em1.empid=dept.empid;
on em1.empid=dept.empid
*
ERROR at line 2:
ORA-00933: SQL command not properly ended

I need to be clear about what exactly difference when we put any condition in INNER JOIN and WHERE Clause. I tried both way and found same results. Even in Statistics Plan not much differences.
1. Here I am using location filter in Inner join condition -
"SELECT I.*, Gl * From Sc1.Item I Inner Join Sc1.Part P On P.Part_Id = I.Part_Id Inner Join Sc1.Location Gl On Gl.Location_Id = I.Location_Id And Gl.Location_Id In ( 1767, 1747,202,1625) Inner Join Sc1.Condition C On C.Condtion_Id = Gl.Condition_Id Where I.Inactive_Ind = 0 And I.Condition_Id != 325
2. Here I am using location filter in Where clause
SELECT I.*, Gl * From Sc1.Item I Inner Join Sc1.Part P On P.Part_Id = I.Part_Id Inner Join Sc1.Location Gl On Gl.Location_Id = I.Location_Id Inner Join Sc1.Condition C On C.Condtion_Id = Gl.Condition_Id Where I.Inactive_Ind = 0 and I.LOCATION_ID in ( 1767, 1747,202,1625) And I.Condition_Id != 325.

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 ?

Is there such a thing as:
NOT LIKE IN (record%, %record, etc)
What I need is NOT IN with the ability to query by wild card. NOT LIKE IN doesn't seem to work for me. Is there another way to do this without having to write out each statement (WHERE NOT LIKE record% AND NOT LIKE %record, etc.)?

We have just migrated from DB version 10 to version 11.2.0.3.We have found out, that we have to do a revision of old queries, because there are probably differencies in the syntax. where are these differencies described? Here is an example, what google didn't told me.... I have some condition where table_1.id = table_2.id ( +) What doesn't mean ( +)?

DECLARE
T_PASSWORD VARCHAR2(40) :=null;
BEGIN
T_PASSWORD := select MAX(TPASSWORD) from APEXPWD;
if :p101_PASSWORD = T_PASSWORD then
I'm not getting the syntax to LOAD the value of APEXPWD.TPASSWORD from the Database into the VARIABLE T_PASSWORD in APEX so that I can compare it against the users PASSWORD. This allows me to compare if the user has a temp password and then redirects them to the correct change password page. Everything is working except getting the T_PASSWORD variable set correctly.

why this code work in 8i but not in 9i, 10g, 11g
declare
type typ_curseur is ref cursor;
l_cursor typ_curseur;
[Code]....
When running in 9,10 or 11 I get the error ORA-22806: not an object or REF. After investigation I found that the problem is the bind variable ":bind.variable". Notice the dot between bind and variable. If i remove the dot or replace it by underscore everything work fine.
I am just looking for some documentation about this problem to know if it was some new restriction starting in 9i and if there is something to set to make it work like in 8i or maybe it will be better to change all our program that are using this kind of syntax. Actually i did not find anything on metalink.

setting up the query/correcting the syntax below so that it calculates the 'number of days difference' between whatever the 'Biggest Date' field value is and whatever the 'current date' is using the 'sysdate'. So far, I've only managed to get the query to calculate the number of days difference (days past due) between the 'need date' and 'estimated delivery date'.
CODESELECT
To_Date(need_date, 'YYYYMMDD') Need_Dt,
To_Date(Case when estimated_delivery > ' ' THEN estimated_delivery ELSE need_date END, 'YYYYMMDD') Biggest_Date,
To_Date(need_date, 'YYYYMMDD') - To_Date(Case when estimated_delivery > ' ' THEN estimated_delivery ELSE need_date END, 'YYYYMMDD') Date_Diff
FROM tableT
WHERE
need_date <= (Case when estimated_delivery > ' ' THEN estimated_delivery ELSE need_date END)
