In APEX I created a page and here a region. The region reports a classic report. I have selected "PL/SQL function body that returns an SQL query" as the source. Here I have also deposited the following code
declare
l_date_string varchar2(32000);
l_date_diff number(4);
x NUMBER := 0;
l_script varchar2(32000);
l_script_pivot varchar2(32000);
new_date varchar(256);
begin
l_date_diff:=TO_DATE(:P2066_DATE_UNTIL, 'dd.mm.yyyy') - TO_DATE(:P2066_DATE_FROM, 'dd.mm.yyyy') ;
While X < l_date_diff+1 Loop
new_date := to_char(TO_DATE(:P2066_DATE_FROM, 'dd.mm.yyyy')+X,'dd.mm.yyyy');
l_date_string := l_date_string || ',''' || new_date || '''';
X := X + 1;
End Loop;
l_date_string := substr(l_date_string,2);
l_script := 'Select * from
(Select
pkey,
to_char(createdformat,''dd.mm.yyyy'') business_date,
regexp_substr(statistics, ''business_\w*'') business_statistics
from
gss.business_data
where
statistics like ''%business_%''
and createdformat between :P2066_DATE_FROM and :P2066_DATE_UNTIL
) ';
l_script_pivot := l_script || ' pivot(
count(pkey)
for business_date
in ('||l_date_string||'))';
sys.htp.p('<li>' || l_script_pivot || ' </li>' );
return l_script_pivot;
end;
The first column, Business_Statistis, is always displayed, the date in the subsequent columns should be displayed dynamically - depending on the selection of the period.
I also spent the respective code according to the time period selection and knew it successfully as a classic report with an SQL query. That's working.
How can I now dynamically update the classic report with a PL / SQL action. That means that depending on the result, the Classic Report is always displayed?
I once selected to use Generic Number of Columns in parallel, with a number of 365. Then he shows me the columns, but the column heading is not the date but Col2, Col3, Col4 and so on
There are a few ways to solve this issue.
Option 1: If you're happy to use "Generic Number of Columns", then select PL/SQL as your "Headings Type". Then define your headings with PL/SQL e.g.
DECLARE
v_heading varchar2(2000);
l_date_diff number(4);
BEGIN
v_headings := 'business_statistics';
l_date_diff:=TO_DATE(:P2066_DATE_UNTIL, 'dd.mm.yyyy') - TO_DATE(:P2066_DATE_FROM, 'dd.mm.yyyy') ;
WHILE X < l_date_diff+1 LOOP
new_date := to_char(TO_DATE(:P2066_DATE_FROM, 'dd.mm.yyyy')+X,'dd.mm.yyyy');
v_headings := v_headings ||':' || new_date ;
X := X + 1;
END LOOP;
END;
Option 2: I assume you are using "PL/SQL function body that returns an SQL query" to get around the "in clause" of the pivot? Another way to fix this is to define your pivot clause as a page item. E.g. P2066_PIVOT_CLAUSE. You can then set the pivot clause with a before header process. Then you can use standard SQL in your report.
i.e.
SELECT * FROM
(SELECT pkey,
to_char(createdformat,'dd.mm.yyyy') business_date,
regexp_substr(statistics, 'business_\w*') business_statistics
FROM
gss.business_data
WHERE
statistics like '%business_%'
AND createdformat BETWEEN :P2066_DATE_FROM AND :P2066_DATE_UNTIL)
PIVOT (COUNT(pkey)FOR business_date in (&P2066_PIVOT_CLAUSE.))

I am working on the this SAS code and would need assistance with joining the two tables below. I am getting errors while trying to join the two tables.
Requirement: i. Left Join Table B to Table A
Table A:
PROC SQL;

, A.MAX_COUNT
, (case WHEN (B.TOTAL_BREACH/Count(distinct a.Report_Date)) * 100 LT MIN_COUNT
THEN 'TRUE' ELSE 'FALSE' END) as NUMBER__UNDER
, (case WHEN (B.TOTAL_BREACH/Count(distinct a.Report_Date)) * 100 GT MAX_COUNT THEN 'TRUE' ELSE 'FALSE' END) as NUMBER__OVER

Table B:
In the table B, i am trying to find the median of the variable Data_M. The code seems to be okay. I only need assistance joining the Table B to table A above.
Proc sql outobs=1; create table median_dt1 as select distinct put(datepart(max(REPORT_DATE)), date9.) as M_Date , median(Data_M) as median_data from transp
WHERE datepart(REPORT_DATE) ge '01-APR-22'd and datepart(REPORT_DATE) le '31-APR-22'd group by BUSINESS_GROUP order by Report_Date Desc; quit;
Thank you in advance!

You're trying to join on b.PORTF_LEVEL2. However, that column doesn't exist in B. The column "PORTF_LEV2" exists, though. Try that?
If that doesn't resolve the issue, please paste the complete error message that you're receiving.
There is a scenario where I receive a string to the bigquery function and need to use it as a column name.
here is the function
CREATE OR REPLACE FUNCTION METADATA.GET_VALUE(column STRING, row_number int64) AS (
(SELECT column from WORK.temp WHERE rownumber = row_number)
);
When I call this function as select METADATA.GET_VALUE("TXCAMP10",149); I get the value as TXCAMP10 so we can say that it is processed as SELECT "TXCAMP10" from WORK.temp WHERE rownumber = 149 but I need it as SELECT TXCAMP10 from WORK.temp WHERE rownumber = 149 which will return some value from temp table lets suppose the value as A
so ultimately I need value A instead of column name i.e. TXCAMP10.
I tried using execute immediate like execute immediate("SELECT" || column || "from WORK.temp WHERE rownumber =" ||row_number) from this stack overflow post to resolve this issue but turns out I can't use it in a function.
How do I achieve required result?
I don't think you can achieve this result with the help of UDF in standard SQL in BigQuery.
But it is possible to do this with stored procedures in BigQuery and EXECUTE IMMEDIATE statement. Consider this code, which simulates the situation you have:
create or replace table d1.temp(
c1 int64,
c2 int64
);
insert into d1.temp values (1, 1), (2, 2);
create or replace procedure d1.GET_VALUE(column STRING, row_number int64, out result int64)
BEGIN
EXECUTE IMMEDIATE 'SELECT ' || column || ' from d1.temp where c2 = ?' into result using row_number;
END;
BEGIN
DECLARE result_c1 INT64;
call d1.GET_VALUE("c1", 1, result_c1);
select result_c1;
END;
After some research and trial-error methods, I used this workaround to solve this issue. It may not be the best solution when you have too many columns but it surely works.
CREATE OR REPLACE FUNCTION METADATA.GET_VALUE(column STRING, row_number int64) AS (
(SELECT case
when column_name = 'a' then a
when column_name = 'b' then b
when column_name = 'c' then c
when column_name = 'd' then d
when column_name = 'e' then e
end from WORK.temp WHERE rownumber = row_number)
);
And this gives the required results.
Point to note: the number of columns you use in the case statement should be of the same datatype else it won't work
I have created the below function that will return workspace details which the loggedin user has access to.
But this function is returning only the first record from the select list.
I need all the records to be displayed as output.
Please modify it and let me know.
CREATE OR REPLACE FUNCTION "F_WORKSPACE_LOGIN_USERS" (
p_email VARCHAR2
) RETURN VARCHAR2 IS
l_error VARCHAR2(1000);
l_workspace VARCHAR2(1000);
l_teams VARCHAR2(1000);
l_team VARCHAR2(1000);
BEGIN
FOR i IN ( SELECT a.name workspace,
a.team_id id
FROM slackdatawarehouse.teams a,
( SELECT TRIM(workspaces) workspaces
FROM alluser_workspaces_fact
WHERE lower(email) = lower(p_email)
) b
WHERE a.team_id IN ( SELECT c.team_id
FROM slackdatawarehouse.team_tokens c
)
OR instr(', '
|| lower(b.workspaces),', '
|| lower(a.name) ) > 0
ORDER BY 1 ) LOOP
l_teams := l_team
|| ','
|| i.id;
l_teams := ltrim(rtrim(l_teams,','),',');
RETURN l_teams;
END LOOP;
END;
Current output is :
T6HPQ5LF7,T6XBXVAA1,T905JLZ62,T7CN08JPQ,T9MV4732M,T5PGS72NA,T5A4YHMUH,TAAFTFS0P,T69BE9T2A,T85D2D8MT,T858U7SF4,T9D16DF5X,T9DHDV61G,T9D17RDT3,T5Y03HDQ8,T5F5QPRK7
Required output is :
T6HPQ5LF7
T6XBXVAA1
T905JLZ62
i need output like above as one by one
I don't know what that code really does (can't test it), but this might be the culprit:
...
RETURN l_teams;
END LOOP;
As soon as code reaches the RETURN statement, it exits the loop and ... well, returns what's currently in L_TEAMS variable. Therefore, move RETURN out of the loop:
...
END LOOP;
RETURN l_teams;
If it still doesn't work as expected (which might be the case), have a look at pipelined functions (for example, on Oracle-base site) as they are designed to return values you seem to be looking for.
A simple example:
SQL> create or replace type t_dp_row as object
2 (deptno number,
3 dname varchar2(20));
4 /
Type created.
SQL> create or replace type t_dp_tab is table of t_dp_row;
2 /
Type created.
SQL> create or replace function f_depts
2 return t_dp_tab pipelined
3 is
4 begin
5 for cur_r in (select deptno, dname from dept)
6 loop
7 pipe row(t_dp_row(cur_r.deptno, cur_r.dname));
8 end loop;
9 return;
10 end;
11 /
Function created.
SQL> select * from table(f_depts);
DEPTNO DNAME

I would like to get a different result to my select statement when a parameter is 0, 1 or 2. I am not very skilled in PLSQL so I am not sure if my code would give the expected result. If i run this code i get a "SQL statement ignored" on line 3.
BEGIN
IF (:PARTYPE = 1) THEN
SELECT * FROM x
WHERE to_date(date) >= (Select to_date(sysdate)from DNV.dual)
ELSE
SELECT * FROM x
WHERE to_date(date) <= (Select to_date(sysdate)from DNV.dual)
END IF;
END;
This is just a example of my SELECT statement. Later this statement will become longer and more complex but I think this shows which results I am trying to get.
Below is a copy of my entire code but because I am not allowed to show this it has become very unreadable:
BEGIN
IF (:PARTYPE = 1) THEN
Select table1.Column1
, table1.Column2
, table1.Column3
, table1.Column4
, table1.Column5
, table1.Column6
, table1.Column7
, table1.Column8
, table1.Column9
, table1.Column10
, table1.Column11
, table1.Column12
, (Select table2.ColumnX From x2 table2 Where somthing) as "something" From x1 table1
WHERE to_date(date) >= (Select to_date(sysdate)from DNV.dual)
Order by columnX
ELSE
Select table1.Column1
, table1.Column2
, table1.Column3
, table1.Column4
, table1.Column5
, table1.Column6
, table1.Column7
, table1.Column8
, table1.Column9
, table1.Column10
, table1.Column11
, table1.Column12
, (Select table2.ColumnX From x2 table2 Where somthing) as "something" From x1 table1
WHERE to_date(date) <= (Select to_date(sysdate)from DNV.dual)
Order by columnX
END IF;
END;
I have created some new code with which i am trying to learn how a case statement works. This might help me with the code above. Unfortunately this code also doesn't work but I think it explanes my situation better. In this excample i use a separate table with data i made up. In some cases user2 is null but user1 is always filled. I want to get all items where user2 equals the parameter but if user2 is null and user1 does equal the paramter i still need that item to apear.
Select t1.user1,
t1.user2
From table t1
Where (Case
When t1.user2 IS NULL Then t1.user1 in (:PARUSER)
ELSE t1.user2 in (:PARUSER)
End Case)
Since the relational operator of the where clause depends on the partype, you cannot do the traditional CASE statement charm here. I'll have to resort with this one:
SELECT * FROM x
WHERE (to_date(date) >= (Select to_date(sysdate)from DNV.dual) AND :PARTYPE = 1)
OR (to_date(date) <= (Select to_date(sysdate)from DNV.dual) AND :PARTYPE != 1)
I'm using Oracle 11g, and I would like to split a column (JobDescription) from the Persons table into separate words.
I.e. If Person A's Job Description is "Professional StackOverflow Contributor", I would like to populate another table with 3 rows containing the 3 words from the Job Description.
From another post here, I managed to get the following which is working for smaller sets of data. But my table contains just less that 500 000 records and the statement has now been running for 2 days and it's still going.
INSERT INTO WORDS (PersonID, Department, Word)
SELECT distinct PersonID, Department, trim(regexp_substr(str, '[^,]+', 1, level))
FROM (SELECT PersonID, Department, trim(Replace(JobDescription, ' ', ',')) str
FROM Persons) t
CONNECT BY instr( str , ',', 1, level - 1) > 0;
Are there another option that might result in quicker results?
For a one-off job, I see no reason not to go procedural. This should be quick enough (250 seconds for a 2.5 million row table on my system). Change the size of the varchar2 variables if your words can be longer than 40 characters.
create or replace procedure tmp_split_job as
TYPE wtype IS TABLE OF NUMBER INDEX BY VARCHAR2(40);
uwords wtype;
w varchar2(40);
i pls_integer;
n pls_integer;
p pls_integer;
cursor c_fetch is select PersonID, Department, JobDescription from Persons where JobDescription is not null;
begin
for v_row in c_fetch loop
n := length(v_row.JobDescription);
i := 1;
while i <= n loop
p := instr(v_row.JobDescription, ' ', i);
if p > 1 then
w := substr(v_row.JobDescription, i, p-i);
i := p + 1;
else
w := substr(v_row.JobDescription, i);
i := n + 1;
end if;
uwords(w) := 1;
end loop;
w := uwords.FIRST;
while w is not null loop
insert into words (PersonID, Department, Word) values (v_row.PersonID, v_row.Department, w);
w := uwords.next(w);
end loop;
uwords.DELETE;
end loop;
end;
