PL/SQL :: Exclude Duplicate Values On SQL Where Clause Statement?
Jul 15, 2013
Are some posibilities to exclude duplicate values do not using sql aggregate functions in main select statement? Priview SQL statement
SELECT * FROM
(
select id,hin_id,name,code,valid_date_from,valid_date_to
from diaries
)
[Code]....
In this case i got duplicate of entry TT2 id 50513 In main select statement cant use agregate functions are even posible to exclude this value from result modifying only the QLRST WHERE clause (TRUNC need to be here)
how to write this query using all three tables in one query statement.
Result:
Input value of "GM" would return "GM@EMAIL.COM"
Input value of "GM" and "GMC" would return "GMC@EMAIL.COM"
If "GM" is supplied, then only return the "GM@EMAIL.COM" email.
If "GM" and "GMC" is supplied, then only return the "GMC@EMAIL.COM" email
Test Case : GM would return "GM@EMAIL.COM" email
Test Case : GM and GMC would return "GMC@EMAIL.COM" email
select email from email a, company b, sub_company c where (company = "GM" but no match found in sub_company) (company = "GM" and sub_company_name = "GMC" match is found in sub_company)
In the following merge statement in the USINg clause...I am using a select stament of one schema WEDB.But that same select statement should take data from 30 schemeas and then check the condition below condition
ON(source.DNO = target.DNO AND source.BNO=target.BNO);
I thought that using UNIONALL for select statement of the schemas as below.
select empno,ename,deptno,employee_status from emp,dept where emp.deptno=dept.deptno and ( employee_status in(Case employee_status when {?Status}=1 then 'A' when {?Status}= 2 then 'T' When {?Status}= 3 then 'A'||','||'T')) OR ( end_date >= {?START_DATE} AND end_date <= {?END_DATE} ) )
Since when i pass employee_status as input 1 it have given me 4 records. When I pass employee_status as input 2 it have given me 3 records. When I pass employee_status as input 3 it should give me 4 records + 3 records=7 records.
4 records for employee_status 'A' 3 RECORDS for employee_status 'T' 7 records for employee_status 'A' AND 'T'
I have two tables Table1 Id1 Name1 1 Jack 2 Jack 3 John
Table2 ID2 Name2 NULL Jack NULL John
I would be assigning ID2 from ID1 based on name match.As Jack has 2 ids when I use the statement UPDATE TABLE2 set id2 = (select distinct ID1 from table1 where table1.name1=table2.name2);
I get an error message as select statement would return more than one row and the update statement fails completely. with the sql statement to update the ID2 as error when we have duplicate records and continue with the update for other records. like table ID2 Name2 ERROR Jack
I'm using pivot query feature of oracle 11g and came across a strange situation where i need to pass a "select statement" in a "in clause" of pivot query.
I have tried with pivot xml but it not giving desired output in sql*plus session.It is giving unreadable output.
select * from (select uin,testing_id,pfa_result from test1) pivot xml (max(pfa_result) as result for (testing_id) in (select distinct testing_id from test1));
[code]....
Here actually i want to use "select distinct id from test1" instead of "in (11,12,13,14,15)". Because i don't know how many id's will be there and of which values. e.g. 11 or 21 or 25.
Want to filter a data using CASE statement in WHERE clause for the following scenario.
Need to Filter tb1.fallback_keyword if the fallback_flag is "Y' or 'N' and pg_number is null.Else no partial search of keyword.
where CASE WHEN (fallback_flg = 'Y' OR fallback_flg = 'N') and (pg_number is NULL ) THEN tb1.fallback_keyword = SUBSTR(key_word,1, INSTR(key_word,'#',-2)) ELSE (tb1.keyword = key_word ) AND (tb1.keyword like regexp_replace(key_word, '[*]+', '%')) END
currently i m going through some dumps for my OCA-11g prep.I came across one sentence :A view cannot have an ORDER BY clause in the SELECT statement.well this statement is false and the explanation given was :
Query operations containing ORDER BY clause are also permitted, so long as the ORDER BY clause appears outside the parentheses.
The following is an example of what I mean: CREATE VIEW my_view AS (SELECT*FROM emp) ORDER BYempno.
but when i tried running the query like this :CREATE VIEW my_view AS SELECT*FROM emp ORDER BYempno ,it worked w/o giving parentheses.
i have master-detail form.in master my bill_id gets generated when new form is open and i copy the same bill_id in detail(tabular)for each item.all the items which i enter in detail form get save the same bill_id which got generated.
in another form(which is tabular) i want to display bill_id's from detail form.but in detail form . There are same bill_id's more than once.but i want to display those bill_id's which are more than once only once.
I need to delete the duplicate values from plsql table OR move the distinct values in plsql table to other plsql table.
how can i do this ?
DECLARE TYPE alist IS TABLE OF VARCHAR2(10) INDEX BY BINARY_INTEGER; p_tbl alist; BEGIN p_tbl(1) := 'A1'; p_tbl(2) := 'B2J'; p_tbl(3) := 'A1'; [code]......
The p_tb1 table contains all the above values including duplicates. Now I need only distinct values to be copied in another plsql table of same type.
I am trying write a script that will return all values (based on the minimum tarif) from the Germany table for any duplicate values. Duplicate values are any values with the same UFI, ZC,limitid,depot. The German table also contains the fields tarif, city, supplier, etc.
Below is the script I have previously used to sort out duplicates. I have tried 50 different ways get it to return just lines for the minimum tariff but haven't been successful.
select * from Germany t where (ufi,zc,limitid,depot) in ( select ufi,zc,limitid,depot from ( select ufi,zc,limitid,depot, count(*) n from Germany t group by ufi,zc,limitid,depot) where n<>1 )
Table contains duplicate data . Have to move data to another table. Criteria: check for duplicate values if duplicate exist move all duplicates except one to the history table. While moving to other table see if the record being moved already exists.

FIRST 4 RECORDS ARE DUPLICATES FROM WHICH 1 RECORD GOES TO w_grp AND ONE GOES TO HISTORY TABLE. THE RECORD WHICH GOES INTO w_grp OUT OF THE DUPLICATES WILL DEPEND ON THE LAST MODIFIED DATE FOR EACH
DISTINCT VALUES GO IN w_grp TABLE DUPLICATE GO INTO match_his TABLE
id name plan code 1 sam normal 5 1 sam normal 6 1 sam special 5 1 sam Special 6
I need to delete data in such a way that one entry with normal and one entry with special plan should remain and should be with different code. Does not matter whether normal stays with 5 or 6 code.
I tried with rowid but it deletes either both normal or both special or returns same code for normal and special.
Is it possible within a CASE statement to put conditions on the date range that I want to pull? IE: am versus pm. The query has to pull specific time ranges for an AM run versus a PM run. ..... FROM table WHERE CASE WHEN TO_CHAR(SYSDATE,'AM') = 'AM' THEN table.date BETWEEN TRUNC(SYSDATE) AND SYSDATE ELSE table.date BETWEEN TRUNC(SYSDATE+12/24) AND SYSDATE
CREATE TABLE prim_tbl (id NUMBER,--- id is not primary key here description VARCHAR2(30));
INSERT ALL INTO prim_tbl VALUES (1,'aad') INTO prim_tbl VALUES (1,'aads') INTO prim_tbl VALUES (2,'bb') INTO prim_tbl VALUES (2,'cc') INTO prim_tbl VALUES (2,'dd') SELECT * FROM dual;
I want to select the ids only one time, i.e my output will have only two rows: one row with id as 1 and other row with id 2 whatever be the description.
desired output sample:
Quote:1, aad 2, bb
I used: select distinct(id),description from prim_tbl;
but it did not give the required result.How can I get it??
I'm going to do some testing, and for that I require to retrieve some data based on a single column e.g test_data_col, which -
1. Has 3 or more count(test_data_col) for a given set of group by columns e.g grp_col1, grp_col2, grp_col3 2. Within the set of rows retrieved, that particular column holds some duplicate values. I don't need the duplicates displayed, just know if duplicates exist or not.
This might explain what I'm trying to do -
grp_col1, grp_col2, grp_col3, test_data_col
1, A, xyz, HELLO 1, A, xyz, HELLO 1, A, xyz, BYE 1, A, xyz, GOODBYE
2, C, pqr, WELCOME 2, C, pqr, GOOD MORNING 2, C, pqr, BAD MORNING
So for condition 1, I do something like this -
SELECT COUNT(test_data_col) cnt, grp_col_1, grp_col2, grp_col3 FROM test_tab GROUP BY grp_col_1, grp_col2, grp_col3 HAVING COUNT(test_data_col) >= 3;
In this same query, I want to do something that will tell me if the aggregate COUNT(test_data_col) has any duplicate values within it. Again, displaying the duplicates is not important here.
SELECT COUNT(test_data_col) cnt, grp_col_1, grp_col2, grp_col3, /*some logic*/ dup_val FROM test_tab GROUP BY grp_col_1, grp_col2, grp_col3 HAVING COUNT(test_data_col) >= 3;With the proper coding to replace /*some logic*/, I get following values -
cnt, grp_col_1, grp_col2, grp_col3, dup_val
4, 1, A, xyz, Y 3, 2, C, pqr, N
I just gave dup_val column to explain what I'm trying to achieve.. any other way to know the existence of duplicates in the count aggregate will be fine.My Oracle version is Oracle Database 11g Enterprise Edition Release 11.1.0.7.0
