SQL & PL/SQL :: Using Decode Function With Group By Rollup?
Oct 18, 2010
I am trying to use decode funtion with GROUP BY ROLLUP.
MY query is working fine when i use this two queris individually
SELECT SUM(SAL),DEPTNO,JOB FROM EMP GROUP BY ROLLUP ((DEPTNO),(DEPTNO,JOB));
SELECT SUM(SAL),DEPTNO,JOB FROM EMP GROUP BY ROLLUP((JOB),(DEPTNO,JOB));
But when i use Decode funtion so that i can combine above two scenarios it is not working
SELECT SUM(SAL),DEPTNO,JOB FROM EMP GROUP BY ROLLUP ( DECODE(:A,'S',((DEPTNO),(DEPTNO,JOB) ),((JOB),(DEPTNO,JOB) ) ) )
my query is some thing like this but having more column in select. when i am firing this query it is giving result but that is not proper,\.
my problem is , like if there are 3 more values for uh.sflowtype (0,1,2) then group by is not working for them and those are coming in different row , i need them to be combined
query is : select substr(uh.sstartdatetime,1,8) DateTime, ( case when uh.sflowtype=7 then 'sms' when uh.sflowtype=9 then 'mms' when uh.sflowtype=10 then 'gprs'
means if C_TYPE_DESC is 'TXIS CAUSAL LEAVE' it return ABSENCE_DAYS but if ABSENCE_DAYS are null it will be return 0 else it should be return Absence_days
List supplier�s name, id, number of pending orders, number of completed orders and number of all orders from this supplier. (my query doesn't include the last part yet).
My tables are as follows:
Suppliers: S_ID NAME ADDRESS PROVINCE PHONE_NUMBER
and this is what I have so far: select name, s_id sum(decode(order_status, 'P',1,0)) pending, sum(decode(order_status, 'C',1,0)) completed from suppliers where s_id in (select supplier_id from orders);
but I still get an error that says "sum(decode(order_status, 'P',1,0)) pending, * ERROR at line 2: ORA-00923: FROM keyword not found where expected"
I assume this is because I'm not properly referencing the orders table.
Table 1 have 3 columns ID, CUS_NAME, LOC insert into table1 values (001,ABC,North); insert into table1 values (002,DEF,South); insert into table1 values (003,GHI,West);
Table 2 have 3 columns ID, CUS_NAME, LOC insert into table2 values (001,ABC,North); insert into table1 values (002,DEF,East); insert into table1 values (003,JKL,South);
Table 3 is Result_Tab table having 8 columns ID, TAB1_CUS_NAME, TAB2_CUS_NAME, Cus_Name_Res, TAB1_CUS_LOC, TAB2_CUS_LOC, Cus_LOC_Res, Comment.
I have written two cursors which fetches data from both the tables and compares each data between each other and inserts the value into the result table.
the code is as follow:
Insert into Result_Tab values (T1.ID, T1.Cus_Name, T2.Cus_Name, decode(T1.Cus_Name,T2.Cus_Name,'Y','N'),T1.LOC, T2.LOC, decode(T1.LOC,T2.LOC,'Y','N'),Null);
Now I want the resul as follows: ID T1.N T2.N N_Res T1.L T2.L L_Res Comment 001 ABC ABC Y North North Y Null 002 DEF DEF Y South East N Loc 003 GHI JKL N West South N Name, Loc
Is there a way wherein i could capture the column names in decode function when it doesn't match, so that I can insert the same in the comment column.
Can we call a function within decode statement. I am able to do the same for simple example function . But In my actual procedure it's giving the error message . Are there any restrictions to call function with in decode statement?
I am trying to use decode function in sql and inside decode function can I use select statement ?
here is my sql
select we.wf_entity_id, decode(object_type_id, 1, select audit_number from ea_audit_general where sys_audit_id=object_id 2,'test', object_type_id ) from wf_entity we where
[code]....
see this
decode(object_type_id, 1, select audit_number from ea_audit_general where sys_audit_id=object_id 2,'test', object_type_id )
I am using oracle 11G database,I have to check length of name column value from employee table and if length(name) > 39 then value should be substr(name,0,39) else value should be name only. i tried below code
select CASE when length(name) > 39,substr(name,0,39) else name END
from employee but its not working ..can I do this using decode too ? ,,which one would be better or this is not a right way ?
I have Two cursor record block..which is attached in form..
My TASK IS
In my first Block, When DBCR Column = 'D' Then in backend this column value should be save as a '1' WHEN DBCR Column = 'C' Then Then in backend this column value should be save as a '2'
My Both Field is on Data Block...
In Property palette of this field can we write any decode condition..so it reflects directly on database.
SQL> SQL> SELECT DECODE(act.statement_flag, NULL, 'Total',act.statement_flag) "Monthly Statement?", 2 COUNT(account_id) "Count", 3 ROUND(((COUNT(account_id)/ (SELECT COUNT(account_id) FROM accounts WHERE account_status_id = consts$.acct_sts_active))* 100),2) || '%' "Percent of Active Accounts" 4 FROM accounts act 5 WHERE act.account_status_id = consts$.ACCT_STS_active 6 GROUP BY ROLLUP(act.statement_flag) SQL> /
Monthly Statement? Count Percent of Active Accounts ------------------ ---------- ----------------------------------------- N 1892 98.08% Y 37 1.92% Total 1929 100%
I want the output to be in the following fashion:
Monthly Statement? Count Percent of Active Accounts ------------------ ---------- ----------------------------------------- Y 37 1.92% N 1892 98.08% Total 1929
And I would also like to know is there another way to find the Percent of Active accounts in the query.
I want to use Analytical function instead of group by clause for below query..
select CASE WHEN ADMT.SOURCESYSTEM ='CLU' THEN COUNT(ADMT.TOTAL_COUNT)*5 ELSE COUNT(ADMT.TOTAL_COUNT) END TOTAL_COUNT from ESMARTABC.ABC_DRVR_MFAILS_TMP ADMT group by ADMT.SOURCESYSTEM
I only want get one record with all columns, only have one clause MAX(END_TIME) But the other column have difference value. when i use MAX(END_TIME) and GROUP BY USER_ID,PROCESS_ID,CASES,... the sql didnot give one record, It give many records
I am trying to use rollup for a total, but it doesn't work because what I'm totaling is too conditional. I even tried adding on the totals to the end using a union and a specialized function, but for some reason, the order by stops working when I do the union (all field aliases and types are the same).I know the structure of the query itself probably isn't the best, how I can get the grand total, The subtotals from the rollup work fine, though.
The order by query runs fine against both parts of the union when they are run individually, but once I make it part of the union - the first part of the order by is an unknown field and the second is not a SELECTed list expression. I've commented out the union here. The statement works fine without it except for the grand total being all 0s. I kind of understand why it's all 0s, but not how to get around that.This is running in Oracle 10g2. I am trying to get totals for decisions by each of the four component values: ex_land, ex_imp,tx_land,tx_imp and then subtotals for each component values.
That works for the following query, but I cannot get a grand total through the rollup.
I'm trying to group sets of data based on time separations between records and then count how many records are in each group.
In the example below, I want to return the count for each group of data, so Group 1=5, Group 2=5 and Group 3=5
SELECT AREA_ID AS "AREA ID", LOC_ID AS "LOCATION ID", TEST_DATE AS "DATE", TEST_TIME AS "TIME" FROM MON_TEST_MASTER WHERE AREA_ID =89 AND LOC_ID ='3015' AND TEST_DATE ='10/19/1994';
[code]....
Group 1 = 8:00:22 to 8:41:22
Group 2 = 11:35:47 to 11:35:47
Group 3 = 15:13:46 to 15:13:46
Keep in mind the times will always change, and sometime go over the one hour mark, but no group will have more then a one hour separation between records.
I read that rownum is applied after the selection is made and before "order by". So, in order to get the sum of salaries for all employees in all departments with a row number starting from 1, i wrote :
select ROWNUM,department_id,sum(salary) from employees group by department_id
If i remove rownum, it gives the correct output. Why can't rownum be used here ?
Which warehouses have pending orders for products, which are not in stock at the warehouse at the moment? Provide warehouse number, id of the product that is not in stock, number of orders issued for this product and total quantity ordered.
The tables I am using are
Warehouses: Name Type ---------------------------------------- W_ID NUMBER(38) CITY VARCHAR2(20) W_SIZE NUMBER(38)
Inventories: Name Type ----------------------------------------- P_ID NUMBER(38) W_ID NUMBER(38) QUANTITY NUMBER(38)
Orders: Name Type ----------------------------------------- ORD_ID NUMBER(38) SUPPLIER_ID NUMBER(38) ISSUING_EMP_ID NUMBER(38) ORDER_DATE DATE ORDER_STATUS CHAR(1)
This is my code so far:
select w.w_id, i.p_id, sum(decode(o.ord_id, ' ', i.p_id, 0)) Orders_issued, select sum(i.quantity) from inventories i orders o,
[code]...
but I get this error:
select sum(i.quantity) * ERROR at line 3: ORA-00936: missing expression
Just working with Unix for the first time and trying to understand this decode statement?
cursor l_cursor is select decode(type||'-'||to_char(line,'fm99999'), 'PACKAGE BODY-1','/'||chr(10), null) || decode(line,1,'create or replace ', '') || decode(type||'-'||to_char(line,'fm99999'), 'JAVA SOURCE-1','and compile ' || type || ' named "' || name || '"' || chr(10) || 'AS' || chr(10), '') || text text from user_source where upper(name) = upper(p_name) order by type, line;
im used to using PL SQL via oracle. but lately ive been doing a lot of mysql and PHP and i really need to use something similar to DECODE in my queries. or am i forced to do the checks via PHP.
