How to write the select query with complex where condition
Hi all,
Can u help me in writing following select query.
select * from zu1cd_corr where time_stamp between firstday and lastday .
In the above query time_stamp contains the date and time.
where as firstday and lastday contains the dates.
I need to compare the date in the time_stamp with the firstday and lastday.
But time_stamp contains the time also and it is char of 14 characters length.
Hi,
If that is the case u can do as advait specified....
if the firstday and secondday are select-options then declare two more variables having 14 character length and then concatenate '000000' to firstday variable and '240000' to last day variable and then write ur query.
CLEAR : lv_firstday,
lv_lastday.
concatenate firstday '000000' to lv_firstday.
concatenate lastday '240000' to lv_lastday.
ranges : r_Date for zu1cd_corr-time_stamp.
r_date-sign = 'I'.
r_date-option = 'BT'.
r_Date-low = lv_firstday.
r_Date-high = lv_lastday.
append r_date.
select * from zu1cd_corr into table it_zu1cd_corr where time_stamp in r_Date.
I hope it helps.

Nagaraj

lt_where = '& = ''&'' '.
REPLACE '&' WITH p_ebeln INTO lt_where.

How to write XSJS Select Query with input parameters
Hello Experts,
I am creating a xsjs file and in that file I am trying to write a Select Query based on a Calculation View
I have tried it the following way:
var query = 'SELECT TOP 100 \"Name\", \"Address\", \"City\", \"Country\" FROM \"_SYS_BIC\".\"Test.HL/AddressView\"'
+ 'WITH PARAMETERS(\'PLACEHOLDER\' = (\'$$P_Name$$\', \' Akhil \'),'
+ '\'PLACEHOLDER\' = (\'$$P_City$$\', \' Lucknow \'))';
But it gives me the "Mixed spaces and tabs error".
How should I write XSJS Select Query with input parameters?
Regards,
Rohit>But it gives me the "Mixed spaces and tabs error".
Mixed spaces and tabs has nothing to do with the syntax of the statement. You used both spaces and the tab in the content - which JSLint doesn't like. Remove the beginning spaces of each line and use only one or the other.
The actual syntax of your statement doesn't look right. The problem is that you are escaping the \ when you don't need to if you are using ' instead of " for your string. You escape with \" in the first line but then escape with \' in the 2nd and 3rd line. That is going to cause serious parsing problems with the command. -
How to write the below query with parameter and is null
Hi, I need to retrive the data if the parameter is passed on the field, else retrive all records whose field is null
Example
CREATE TABLE DEPT
(DEPTNO NUMBER(2),
DNAME VARCHAR2(14),
LOC VARCHAR2(13) );
INSERT INTO DEPT VALUES (10, 'ACCOUNTING', 'NEW YORK');
INSERT INTO DEPT VALUES (20, 'RESEARCH', 'DALLAS');
insert into dept values (30, 'SALES', 'CHICAGO');
INSERT INTO DEPT VALUES (40, 'OPERATIONS', 'BOSTON');
alter table dept add(object_id number);
insert into dept values (50, 'OPERATIONS', 'BOSTON',1);
insert into dept values (60, 'OPERATIONS', 'BOSTON',1);
INSERT INTO DEPT VALUES (70, 'OPERATIONS', 'BOSTON',2);
select * from dept where object_id =:p_object_id
If i pass the object_id as 1 , it shloud retrive the values of dept with object_id 1, but if i dont pass the object_id, it should retrive all the records whose object_id is null
IF 1 is passed, as object id , it should retrive, 50, 60, if 1 is not passed as object_id it should retive 10,20,30,40
It works fine for me seperately as,
select * from dept where object_id =:p_object_id -- 1
select * from dept where object_id is null;
Is this possible to do in single query.
ThanksSELECT *
FROM dept
WHERE object_id = :p_object_id
OR (object_id is null and :p_object_id is null)
is one approach. It's a bit verbose but the meaning is clear. If you can identify a value that would never appear in the data (-1 for example)
WHERE nvl( object_id, -1 ) = nvl(p_object_id, -1 );

Select query with optional where condition
Hi,
Can Anybody help me out in the following problem?
I have the following query in a procedure.
SELECT replace(shipper_name,'\',' ') as shipper,
sum(teus / cntSailings) as teus
FROM VW_CONTRIBUTION,
VW_TOTAL_SAILINGS
WHERE VW_CONTRIBUTION.dir = VW_TOTAL_SAILINGS.DIR
AND VW_CONTRIBUTION.line = VW_TOTAL_SAILINGS.LINE
AND VW_CONTRIBUTION.accounting_month = VW_TOTAL_SAILINGS.ACCOUNTING_MONTH
AND VW_CONTRIBUTION.accounting_year = VW_TOTAL_SAILINGS.ACCOUNTING_YEAR
AND VW_CONTRIBUTION.Principal = arg_principal
AND VW_CONTRIBUTION.Dir = arg_direction
AND VW_CONTRIBUTION.line in ( arg_service )
AND VW_CONTRIBUTION.POL_country = arg_pol
AND VW_CONTRIBUTION.POd_country = arg_pod
AND VW_CONTRIBUTION.salesOffice = arg_SalesOffice
AND VW_CONTRIBUTION.salesregion = arg_SalesRegion
AND VW_CONTRIBUTION.cargo_type = arg_txtCargoType
AND VW_CONTRIBUTION.eqgroup = arg_ContType
AND VW_CONTRIBUTION.eq_size = arg_txtSize
AND VW_CONTRIBUTION.acct_date between arg_from_date and arg_end_date
GROUP BY shipper_name
ORDER BY teus desc;
Here some of the arguments are optional(Eg : VW_CONTRIBUTION.salesOffice, AND VW_CONTRIBUTION.eqgroup etc. ) and the values can be null. When they are null, I want them to be excluded from the where condition. Can anybody suggest me a solution for this?
Thanks,
Shalet.I guess i misunderstood your original question.
The clause
AND (VW_CONTRIBUTION.salesOffice = arg_SalesOffice OR VW_CONTRIBUTION.salesOffice IS NOT NULL)
will cause the where clause to evaluate to FALSE anytime salesOffice IS NULL so the record will be excluded.
I thought you were asking how to not compare the value if the field contained a NULL.
Glad you found what you wanted. -

rincyHi,
One thing I understood my your issue is you want to perform, execution of query once or fetch the results sets my minimizing the number of times executions of queries. It would be hard for us to check in this way, atleast provide some temporary data and some business rules. Only I can IN, >, < (queries logical conditons on inner query)

Tirumala1. SELECT INTO
Below method will create table when data is inserted from one table to another table. Its useful when you need exactly same datatype as source table.
Use AdventureWorks2008R2;
Go
---Insert data using SELECT INTO
SELECT AddressLine1, City
INTO BothellAddresses
FROM Person.Address
where City = 'Bothell';
GO
---VERIFY DATA
Select AddressLine1, City
FROM BothellAddresses
---DROP TABLE
DROP TABLE BothellAddresses
GO
2. INSERT INTO SELECT
Below method will need table to be created prior to inserting data. Its really useful when table is already created and you want insert data from
another table.
Use AdventureWorks2008R2;
Go
---Create Table
CREATE TABLE BothellAddresses (AddressLine1 NVARCHAR(60), City NVARCHAR(30))
---Insert into above table using SELECT
INSERT INTO BothellAddresses(AddressLine1, City)
SELECT AddressLine1, City
FROM Person.Address
where City = 'Bothell';
---VERIFY DATA
Select AddressLine1, City
FROM BothellAddresses
---DROP TABLE

How to optimize the select query that is executed in a cursor for loop?
Hi Friends,
I have executed the code below and clocked the times for every line of the code using DBMS_PROFILER.
CREATE OR REPLACE PROCEDURE TEST
AS
p_file_id NUMBER := 151;
v_shipper_ind ah_item.shipper_ind%TYPE;
v_sales_reserve_ind ah_item.special_sales_reserve_ind%TYPE;
v_location_indicator ah_item.exe_location_ind%TYPE;
CURSOR activity_c
IS
SELECT *
FROM ah_activity_internal
WHERE status_id = 30
AND file_id = p_file_id;
BEGIN
DBMS_PROFILER.start_profiler ('TEST');
FOR rec IN activity_c
LOOP
SELECT DISTINCT shipper_ind, special_sales_reserve_ind, exe_location_ind
INTO v_shipper_ind, v_sales_reserve_ind, v_location_indicator
FROM ah_item --464000 rows in this table
WHERE item_id_edw IN (
SELECT item_id_edw
FROM ah_item_xref --700000 rows in this table
WHERE item_code_cust = rec.item_code_cust
AND facility_num IN (
SELECT facility_code
FROM ah_chain_div_facility --17 rows in this table
WHERE chain_id = ah_internal_data_pkg.get_chain_id (p_file_id)
AND div_id = (SELECT div_id
FROM ah_div --8 rows in this table
WHERE division = rec.division)));
END LOOP;
DBMS_PROFILER.stop_profiler;
EXCEPTION
WHEN NO_DATA_FOUND
THEN
NULL;
WHEN TOO_MANY_ROWS
THEN
NULL;
END TEST;The SELECT query inside the cursor FOR LOOP took 773 seconds.
I have tried using BULK COLLECT instead of cursor for loop but it did not help.
When I took out the select query separately and executed with a sample value then it gave the results in a flash of second.
All the tables have primary key indexes.
Any ideas what can be done to make this code perform better?
Thanks,
Raj.As suggested I'd try merging the queries into a single SQL. You could also rewrite your IN clauses as JOINs and see if that helps, e.g.
SELECT DISTINCT ai.shipper_ind, ai.special_sales_reserve_ind, ai.exe_location_ind
INTO v_shipper_ind, v_sales_reserve_ind, v_location_indicator
FROM ah_item ai, ah_item_xref aix, ah_chain_div_facility acdf, ah_div ad
WHERE ai.item_id_edw = aix.item_id_edw
AND aix.item_code_cust = rec.item_code_cust
AND aix.facility_num = acdf.facility_code
AND acdf.chain_id = ah_internal_data_pkg.get_chain_id (p_file_id)
AND acdf.div_id = ad.div_id
AND ad.division = rec.division;ALSO: You are calling ah_internal_data_pkg.get_chain_id (p_file_id) every time. Why not do it outside the loop and just use a variable in the inner query? That will prevent context switching and improve speed.

Select query for rows where condition 1
Say I have a table, tb1, that has the following entries:
FName LName
Code
John Doe
xxx
Jane Doe
xxx
Steve Harper
x
Barrak Obama
x
George Bush
xxxx
Bill Clinton
xx
I'd like to write a select query that only lists the rows where the count for Code is > 1, i.e not display the last two rows from the above entry. How would I go about writing that select query.
Thanks.Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data should
use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums.
>> Say I have a table, tb1, that has the following entries: <<
Are you this rude or really ignorant and too lazy to read the Netiquette at the start to this forum? Why do you think you do not need a key? No DDL? No constraints? And , why, why do you think that “tb1” is a precise, ISO-11179 conforming table name?
Let's make this a table of rude posters rated on a 4-star scale.
CREATE TABLE Rude_Posters
(first_name VARCHAR(15) NOT NULL,
last_name VARCHAR(15) NOT NULL,
PRIMARY KEY (first_name, last_name),
rudeness_code VARCHAR (4) NOT NULL
CHECK (rudeness_code IN ('x', 'xx', 'xxx', 'xxxx'));
INSERT INTO Rude_Posters
VALUES
('John', 'Doe', 'xxx'),
('Jane', 'Doe', 'xxx'),
('Steve', 'Harper', 'x'),
('Barrack', 'Obama', 'x'),
('George', 'Bush', 'xxxx'),
('Bill', 'Clinton', 'xx');
>> I'd like to write a SELECT query that only lists the rows where the count for rudeness_code is > 1, i.e not display the last two rows from the above entry. <<
The rudeness scale is based on stars, so to ask for an integer value is like saying “on a scale from 1 to 10, what is the color of your favorite letter of the alphabet?”
Next, the number of stars and your narrative do not match. Did you want to say WHERE rudeness_code IN ('xx' 'xxx', 'xxxx')?
Please stop programming SQL until you have gotten more education. At this point, you do not know enough to ask a question.

all the rows should not be deleted if one of the field in gt_sim eq 'R'.
how to check this conditiondear jayanthi,
ok if i am coding like that as u mentioned ,
it will exit the loop when first time the field value is 'R'.
if any of the selected rows contains field value 'R'. it shold not delete all the selected rows.
as u suggested it will not delete after first time the field value is r.
i am deleting it by tab index so,
suppose if i am selecting the row without field value R say its tabix is 1.
the next row with tabix 2 with field value R.
it deletes the first row and exits , it should not delete the first row also. -
i am writting a selection and i want to select from the table HRP1001 only the rows that created this year
i wrote
select *
into itab
from hrp1001
where concatenate begda(4) eq sy-datum(4).
why its not working ?Hi Ami,
concatenate and partial field selection are not part of Open SQL. You could use a pattern:
concatenate sy-datum(4) '%' into lw_year_pattern.
select * into itab
from hrp1001
where begda like lw_year_pattern.
or you could use between, probably more efficient:
lw_date_from = lw_date_to = sy-datum.
lw_date_from+4(4) = '0101'.
lw_date_to+4(4) = '1231'.
select * into itab
from hrp1001
where begda between lw_date_from and lw_date_to.
Good luck,

Single SQl Query with different where conditions
Experts,
I have a requirement to design a report. Here are the details
I have Report table layout
Profit center Gross sales (This Year) Gross Sales (Last Year) % change Year of Year
The Report has a selection of entering the Start Date.
I have a single table in oracle which has profit center and Gross Sales Values on daily basis.
I want to write a single sql query to calculate both Gross Sales current year and Gross Sales Last Year. I can calculate Gross Sales Current Year by putting the where condition for start date = Current Year Date which i pass through report. I want to calculate the Gross Sales Last Year in the Same query by putting the different where condition i.e start date = Last Year date based on the date input.
I dont know how to put two where conditions in single query for two different columns.
Any help will be appreciated.
Thanks in advance
Regards
Santoshinstead of changing your where clause couldn't you just determine the yearly totals from your table and then use the lag statement to get last years total?
something like this?
I just made up 10,000 days worth of sales and called it fake table it is supposed to represent a variant of the table you were describing as your base table.
with fake_table as
( select trunc(sysdate + level) the_day,
level daily_gross_sales
from dual
connect by level < 10001
select yr, year_gross_sale, lag(year_gross_sale) over (order by yr) prev_year_gross_sale,
(year_gross_sale - lag(year_gross_sale) over (order by yr))/year_gross_sale * 100 percent_change
from
(select distinct yr, year_gross_sale from
select the_day,
daily_gross_sales,
extract(year from the_day) yr,
extract(year from add_months(the_day,12)) next_yr,
sum(daily_gross_sales) over (partition by extract(year from the_day)) year_gross_sale
from fake_table
order by yr

How to implement in CMP(Entity bean)
thank uat this point mapping to do this king of query would be on the container specific file. I will tellyou how this is done on a Orion App server. I bet that others are close to the same.
first you make a finder method in your bean for the enploy name:
Collection findBigClerk();
Orion generates a file from the ejb-jar.xml file called orion-ejb-jar.xml. this is where the O/R mapping is changed for the beans.
each method in a bean has short definition
<finder-method query="EMP.SAL>1000 and EMP.JOB='CLERK'">
Assuming that the CMP is mapped to the EMP table when you call findbigClerk it will add the above query to as a WHERE clause.
Then get the name from the interface.
Again, this is how I would do this on an Orion App server. Others will be simular until O/R mapping is moved from server-specific to the ejb-jar.xml file
hope this helps a little -
