PL/SQL :: Difference - In Conditions (Join And Where Clause)
Sep 19, 2013
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.
You think i can do a from clause with conditions ??
The reason is that i need to retrieve fields from different schemas depending on a column in a common table
let s say the column CRITERIA_COL is in table Common If COMMON.CRITERIA_COL has value 1 then the select query should fetch results from the schema : SCHEMA1.MY_TABLE If COMMON.CRITERIA_COL has value 2 then the select query should fetch results from the schema : SCHEMA2.MY_TABLE If COMMON.CRITERIA_COL has value 3 then the select query should fetch results from the schema : SCHEMA3.MY_TABLE
Something like this:
Select my_Col1, my_Col2 from (case COMMON.CRITERIA when '1' then SCHEMA1.MY_TABLE when '2' then SCHEMA2.MY_TABLE when '3' then SCHEMA3.MY_TABLE )
but that is not working .By the way my query is not just that, it s a more complicated query, that s just the portion I am having trouble with .
I am trying to run an SQL query which refers/joins around 10 tables.In my case I would want to add an if-else or case condition in the WHERE clause of select query
For example
select a.column1, b.column1, c.column1, d.column1 from a, b, c, d WHERE a.column2 = b.column2 AND (if a.column3 = 10 then ( I want 2 conditions to be AND b.column2 = c.column2) added else after WHERE clause as AND...) AND b.column2 = d.column2 ) AND d.column2 = a.column2
Have 3 tables table1 (campaignid,promoflag) table2 (campaignid,projectid,campaigndesc) table3 (projectid,promoflag,projectstart,projectend)
I am to update table 1 promoflag with value from promoflag in table3
Update table1 set promoflag = table3.promoflag
I would like to make sure only appropriate record is updated therefore want to use where clause condition but the primary key for table1 and table3 are different, the only link can be found on table2.
I want to use condition where table1.campaignid=table2.campaignid and table2.projectid=table1.projectid
Have used the following without success:
Scenario 1
Update table1 SET promoflag = table3.promoflag FROM table1 inner join table2 on table1.campaignid = table2.camapaignid inner join table3 on table2.projectid = table3.projectID;
Error at line 1 ORA-00933: SQL command not properly ended
Scenario 2 with real table/column names
Update UA_CAMPAIGNEXTATTR SET CFPROMOTABLE = LMUK_PROJECT_AUDIENCE_GRID.GRID_AUD_CFPROMOTABLE FROM UA_CAMPAIGNEXTATTR,UA_CAMPAIGN,LMUK_PROJECT_AUDIENCE_GRID WHERE UA_CAMPAIGNEXTATTR.CAMPAIGNID = UA_CAMPAIGN.CAMPAIGNID AND UA_CAMPAIGN.PROJECTID = LMUK_PROJECT_AUDIENCE_GRID.GRID_AUDIENCE_ID; Error at line 2 ORA-00933: SQL command not properly ended
It appears to get block with the 'FROM' statement (was underlined in red)
I putted in a table "conditions" some rules (if conditions) and I want to read and execute those conditions in another table "list_parameters" in pl/sql procedure.
conditions : ID||||||||||||||RULE 1-----------(param1 = F) 2-----------(param2 is null) .....
In my Project, there are many queries have join conditions between Number and Vrahchar2. Will it give any wrong results or Invalid Number exception even the varchar2 column always contains the number data?
Example: Select * from Table_t1 t1, table_t2 t2 where t1.num_col = t2.var_col -- Here var_col always hold only numaric data.
SELECT MAX(fndattdoc.LAST_UPDATE_DATE ) as LAST_UPDATE_DATE, MAX(DECODE(fndcatusg.format,'H', st.short_text,NULL,st.short_text, NULL)) as COMMENTS, MAX(fnddoc.description) as REASON FROM fnd_attachment_functions fndattfn, fnd_doc_category_usages fndcatusg, fnd_documents_vl fnddoc, fnd_attached_documents fndattdoc, fnd_documents_short_text st, fnd_document_categories_tl fl, WSH_NEW_DELIVERIES DLVRY [code]....
I have three tables, I have to merge those three tables, all three tables having same conditions and filter conditions(in each table one filter condition changed), I highlighted in the red difference the filter conditions in each table, finally my result should be 7 columns like
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 ?
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:
' 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 was practicing on Recursive Subquery Factoring based on oracle examples available in the documentation URL....I was working on an example which prints the hierarchy of each manager with his/her related employees. Here is how I proceed.
WITH tmptab(empId, mgrId, lvl) AS ( SELECT employee_id, manager_id, 0 lvl FROM employees WHERE manager_id IS NULL UNION ALL SELECT employee_id, manager_id, lvl+1 FROM employees, tmptab WHERE (manager_id = empId) [code]....
107 rows selected.
SQL> However, by accident, I noticed that if instead of putting a comma between the table names I put CROSS JOIN, the very same query behaves differently.That is, if instead of writing
UNION ALL SELECT employee_id, manager_id, lvl+1 FROM employees, tmptab WHERE (manager_id = empId)I write . . . UNION ALL SELECT employee_id, manager_id, lvl+1 FROM employees CROSS JOIN tmptab WHERE (manager_id = empId)I get the following error message ERROR at line 4: ORA-32044: cycle detected while executing recursive WITH query
I remember, oracle supports both comme notation and CROSS JOIN for Cartesian product (= cross product). For example
SQL> WITH tmptab1 AS 2 ( 3 SELECT 'a1' AS colval FROM DUAL UNION ALL 4 SELECT 'a2' AS colval FROM DUAL UNION ALL 5 SELECT 'a3' AS colval FROM DUAL 6 ), [code]....
SQL> So if both comma notated and CROSS JOIN have the same semantic, why I get a cycle for the above mentioned recursive subquery factoring whereas the very same query works pretty well with comma between the table names instead of CROSS JOIN? Because if a cycle is detected (ancestor = current element) this means that the product with CROSS JOIN notation is generating some duplicates which are absent in the result of the comma notated Cartesian product.
I have one table in database that contains 3 foreign keys to another tables(this three tables name are: manager,worker and employee). in each row only one foreign key is filled.I need to write one query that with attention which column of fk is filled in where clause specified condition is performed. I write simple query in jpa but doesn't work properly
select b from allEmployees b where b.manager.name= :name OR b.worker.name = :name OR b.employee.name= :name
I would like resolve an issue, I would like to know if is there any posibility to filter particular conditions using sql, the example that Im going to describe below shows these conditions:
create table t1 ( month number, club char(2), total_subs number )
I created a procedure with four in parameters and 1 out parameter is there in this i want to check if any parameters is null or any two parameters are null or any three parameters are null...like this i checked(16 conditions) for all combinations i put if conditions but can i use execute immediate instead of all 16 conditions?
I need to put amount '0' if the row exist but has no amount in my "where " conditions. the orginal commad is :
select t.aaa, count (t.bbb), sum (t.ccc) from nrb t where t.vvv IN ('3','4','5','6','D','E','F') and t.ddd like '50%' and t.eee >= TO_DATE('2012/03/21','YYYY/MM/DD') and t.eee <= TO_DATE('2012/07/21','YYYY/MM/DD') group by t.aaa order by t.aaa
and the result is : "result" tab in excel atached file.i need this result: "result 2" tab in excel atached file.
I am new to the forum as well as SQL programing and I need to have the following criteria writen in my WHERE so all three of these criterias are included in the same report (perhaps, each will have its own section).
with tmp_tbl as (select 'H1' as hh_id, 'C1' as cust_id, 2 as f_rnk, 'F' as gender, to_date('20130102','YYYYMMDD') as purch_dt, to_date('20100203','YYYYMMDD') first_dt from dual union select 'H1' as hh_id, 'C2' as cust_id, 1 as f_rnk, 'M' as gender, to_date('20130102','YYYYMMDD') as purch_dt, to_date('20100303','YYYYMMDD') first_dt from dual union select 'H1' as hh_id, 'C3' as cust_id, cast(null as number) as f_rnk, 'U' as gender, to_date('20130103','YYYYMMDD') as purch_dt, [code].....
Now i need to rank each cust_id in each hh_id based on below conditions.
1) If atleaset one cust_id in hh_id has f_rnk then gender 'F' with highest f_rnk (more then one F with same f_rnk then the one with oldest first_dt), if no 'F' then gender 'U' with highest f_rnk ((more then one F with same f_rnk then the one with oldest first_dt)), if no 'F' and 'U' then consider 'M' (more then one M with same f_rnk then the one with oldest first_dt).
2) If the above is not met (no cust_id in hh_id has f_rnk populated) then i've to rank based on purch_dt. Gender 'F' with recent purch_dt (if more than one F in household with same purch_dt then the one with oldest first_dt), if no 'F' then gender 'U' with recent purch_dt (if more than one U in household with same purch_dt then one with oldest first_dt), if no 'F' and 'U' then consider 'M' (more than one M in household with same purch_dt then the one with oldest first_dt).
3) If the above criteria is also not met, then rank based on gender_cd. Gender 'F' will have first preference then 'U' and then 'M'.
My output :
HH_ID CUST_ID F_RNK GENDER PURCH_DT FIRST_DT F_RNK_RANK PURCH_RANK GENDER_ONLY_RANK ----- ------- ---------- ------ ----------- ----------- ------------ ------------ ----------------- H1 C1 2 F 1/2/2013 2/3/2010 1 H1 C2 1 M 1/2/2013 3/3/2010 2 H1 C3 U 1/3/2013 4/3/2010 3 H2 C4 F 4/3/2013 10/2/2009 2 H2 C5 M 5/5/2013 8/8/2010 1 H3 C6 F 5/6/2008 1 H3 C6 M 7/8/2010 2
I've tried below query with one condition, but it's giving f_rnk_rank for all records. How can i include multiple conditions in the rank function.
with tmp_tbl as (select 'H1' as hh_id, 'C1' as cust_id, 2 as f_rnk, 'F' as gender, to_date('20130102','YYYYMMDD') as purch_dt, to_date('20100203','YYYYMMDD') first_dt from dual union select 'H1' as hh_id, 'C2' as cust_id, 1 as f_rnk, 'M' as gender, to_date('20130102','YYYYMMDD') as purch_dt, to_date('20100303','YYYYMMDD') first_dt from dual union select 'H1' as hh_id, 'C3' as cust_id, cast(null as number) as f_rnk, 'U' as gender, to_date('20130103','YYYYMMDD') as purch_dt, s hh_id, 'C5' as cust_id, [code]....
CASE WHEN (EP.ORDER_NUMBER IS NOT NULL AND ATD.IS_DISCONNECT_CREDIT = 1 ) THEN ......... ...... END
In my case when I club two conditions after WHEN in case statement , everytime the first condtion is satisfied (i.e EP.ORDER_NUMBER IS NOT NULL) it is entering into the loop.
Irrespective of using AND or OR after the first condition I am getting the same results.
I want to enter the CASE statement only when both the conditions (1st and 2nd )are satisfied
While there's numerous QAs about inserting an image into the DB using the Data Block, how does one remove an image? Obviously there's the "UPDATE ... SET X = EMPTY_BLOB();", however, that kills the Data Block/Form's flow, and it doesn't update.
I've tried a few things:
* :CONTROL.IMG1 := NULL; (bad bind variable) * :CONTROL.IMG1 := EMPTY_BLOB(); (some other error, probably as above)
I have a requirement where i need to retain latest 3 records based on creation date for each customer_id and delete the older records. The customer_ id or contract_number data in the test table are not unique.
Sample Table Script:
CREATE TABLE TEST ( CUSTOMER_ID VARCHAR2(120 BYTE) NOT NULL, CONTRACT_NUMBER VARCHAR2(120 BYTE) NOT NULL, CREATION_DATE DATE NOT NULL ); [code]...
Scenario 1 Query should check for priority record(25), if the start_date and end_date of that priority record is the max in that group, records will not have any split.output will be the same.
DC Store St Date End date Priority 955 3 1/1/2010 12/31/9999 25 966 3 4/5/2011 10/10/2011 50 977 3 10/12/2011 12/12/2012 100
output
DC store St Date End date Priority Rank 955 3 1/1/2010 12/31/9999 25 1 966 3 4/5/2011 10/10/2011 50 2 977 3 10/12/2011 12/12/2012 100 3
Scenario 2 If priority record is not covering the max range, then split the records as shown below,
1. during the time period 1/1/2011 & 4/30/2011 there were no other DC for that store so rank would be 1
2. the next range would be 5/1/2011 to 6/29/2011 we have 2 records in service so the record with low priortiy would be ranked 1 and second priority would be ranked 2
3. similarly, for 6/30/2011 to 10/1/2011 we have 3 records in service and it will be ranked accordingly on the priority.
DC Store St Date End date Priority 966 3 6/30/2011 10/1/2011 25 955 3 5/1/2011 11/30/2011 50 977 3 1/1/2011 12/31/2011 100
output
DC store St Date End date Priority Rank 977 3 1/1/2011 4/30/2011 100 1 955 3 5/1/2011 6/29/2011 50 1 977 3 5/1/2011 6/29/2011 100 2
[code]....
Scenario 3 This works similar to scenario 2
DC Store St Date End date Priority 966 3 2/1/2011 12/31/2011 25 955 3 1/1/2011 12/31/2012 50 977 3 5/1/2011 06/31/2011 100
output
DC store St Date End date Priority Rank 955 3 1/1/2011 1/31/2011 50 1 966 3 2/1/2011 12/31/2011 25 1 955 3 2/1/2011 12/31/2011 50 2 977 3 5/1/2011 6/30/2011 100 3 955 3 1/1/2012 12/31/2012 50 1
Note: Number of records in the input can vary and ther can be duplicates in the date interval
I am adding condition in color to my existing query but my query taking too long time after that. This condition calculates last 3 month end dates from given COB (20110516).
SUMMARY is my summarized table and COB is my reference table
Without adding condition in query it gives INDEX (RANGE SCAN)--PK_SUMMARY(INDEX(UNIQUE)) After adding condition in query it gives INDEX(FAST FULL SCAN)--PK_SUMMARY(INDEX(UNIQUE))
how can i keep RANGE SCAN even after adding my new conditions?
SELECT distinct COB.COB_ID_C, SUMMARY.SUMM_COB_ID_C FROM
