I am very new to Oracle; I have written two stored procedures where they have both different parameters. I would like to combine the queries in that two stored procedures into single query in a single stored procedure, and make sure it supports any criteria.
These are the stored procedures:
procedure usp_testsp1(RC1 OUT RCT1,
in_dep_Id IN number,
in_Org_id IN number,
in_emp_no IN number)
is
begin
select emp.Name as name,select emp.phone as phone,select emp.Race as
race
from employee emp
JOIN
Project prj ON
emp.ProjectId=prj.ProjectId
JOIN Project_Org Prorg
ON prj.ProjectId=Prorg.ProjectId
JOIN Organization Org1
ON Prorg.OrgId=Org1.OrgId
JOIN Organization Org2
ON emp.OrgId=Org2.OrgId
AND Org2.OrgType=0
WHERE (upper(emp.emp_No) in (in_emp_No ))
AND Prorg.OrgId=in_Org_id
AND Org2.OrgId=in_dep_Id
end;
procedure usp_testsp2(RC1 OUT RCT1,
in_dep_Id IN number,
in_Org_id IN number,
in_vendor_id IN raw,
in_vendor_startdate IN date,
in_vendor_enddate IN date)
is
begin
OPEN RC1 FOR
select emp.Name as name,select emp.phone as phone,select emp.Race as
race
from
from employee emp
JOIN
Project prj ON
emp.ProjectId=prj.ProjectId
JOIN Project_Org Prorg
ON prj.ProjectId=Prorg.ProjectId
JOIN Organization Org1
ON Prorg.OrgId=Org1.OrgId
JOIN Organization Org2
ON emp.OrgId=Org2.OrgId
AND Org2.OrgType=0
INNER JOIN vendor_Emp
ON emp.employeeid=vendor_emp.employeeid
INNER JOIN Vendor
ON Vendor.VendorId=Vendor_emp.VendorId
WHERE Prorg.OrgId=in_Org_id
AND Org2.OrgId=in_dep_Id
AND Vendor.VendorId=in_vendor_id
AND vendor.StartDate=in_vendor_startdate AND Vendor.EndDate=in_vendor_enddate
end;
My objective is to combine the queries within these two separate procedures into a single query such that if I combine all the parameters, I have in_emp_no, in_vendor_id, in_vendor_startdate, in_vendor_enddate apart from the common parameters any of the parameters can be null and I want to make sure that those things won't affect the rest of the query even though its not null
For ex i have only in_emp_no ='xxxx' and common inputs rest of the params like
in_vendor_id etc is null.
I would like to make my query to work even with single paramter to filter the result set
NOTEWithout using Dynamic SQL
Thanks

You can make columns in the query behave as optional, as far as your join's go, you may need to play with various combinations to make sure everything works.
Sample Table
create table sqltest (
empid number,
name varchar2(10),
orgid number,
depid number,
vendorid number);
insert into sqltest values(1,'BoB',1,1,21);
insert into sqltest values(2,'Chuck',1,1,21);
insert into sqltest values(3,'Mary',1,2,21);
insert into sqltest values(4,'Jane',1,2,22);
insert into sqltest values(5,'Rick',2,1,22);
insert into sqltest values(6,'Samir',2,6,23);
insert into sqltest values(7,'Kirk',3,6,23);
insert into sqltest values(8,'Alex',3,9,23);
commit;
Sample Proc
create or replace procedure calltest (
rc1 out SYS_REFCURSOR,
pempid number,
porgid number,
pdepid number,
pvendorid number)
is
begin
open rc1 for
select * from sqltest
where
(pempid IS NULL OR empid = pempid) and
(porgid IS NULL OR orgid = porgid) and
(pdepid IS NULL OR depid = pdepid) and
(pvendorid IS NULL OR vendorid = pvendorid);
end;
Sample Call
set autoprint on;
var vcur refcursor;
declare
begin
calltest(rc1=>:vcur,pempid=>NULL,porgid=>1,pdepid=>NULL,pvendorid=>NULL);
--calltest(rc1=>:vcur,pempid=>NULL,porgid=>1,pdepid=>2,pvendorid=>NULL);
--calltest(rc1=>:vcur,pempid=>NULL,porgid=>1,pdepid=>2,pvendorid=>22);
--calltest(rc1=>:vcur,pempid=>NULL,porgid=>NULL,pdepid=>NULL,pvendorid=>23);
end;

I have a table from which I want to generate 18 digit code.
Below is the 18 digit code sample which I want.
R-AP-AP01-SMT-4567
Also for generating the above sample code, here is the data and its logic:
R - Fix value
AP – (2 digit state code from STATE column)
EAST- (From ZONE_NAME column from query below
SMT – (From FORMAT_CODE column from below query)
4567 – (From Store Code column from below query)
SELECT STATE, STORE_CODE, ZONE_NAME FROM TBL_RRSOC_STORE_INFO;
AND
select FORMAT_CODE from TBL_SITE_STORE_FORMAT;
How can it be achieved?
Update
Below is the table description
Table name:- TBL_RRSOC_STORE_INFO
Name Null Type
--------------------------- -------- --------------
RRSOC_ID NOT NULL NUMBER
STORE_CODE NOT NULL NVARCHAR2(55)
STATE NVARCHAR2(55)
SLP_STATE NVARCHAR2(100)
FORMAT_GROUP NVARCHAR2(100)
Table name:- TBL_SITE_STORE_FORMAT
Name Null Type
------------ ---- -------------
ID VARCHAR2(20)
STORE_FORMAT VARCHAR2(100)
ISACTIVE VARCHAR2(3)
FORMAT_GROUP VARCHAR2(100)
FORMAT_CODE VARCHAR2(50)
The way you put it, you'd join those tables somehow (cross join is as good as any other, as you didn't explain it better) and concatenate column values.
Something like this:
SQL> with
2 tbl_rrsoc_store_info (state, store_code, zone_name) as
3 (select 'AP', 'EAST', 'SMT' from dual union all
4 select 'NY', 'WEST', 'XYZ' from dual
5 ),
6 tbl_site_store_format (format_code) as
7 (select 4567 from dual)
8 --
9 select 'R' ||'-'|| r.state ||'-'|| r.store_code ||'-'|| r.zone_name ||'-'|| s.format_code result
10 from tbl_rrsoc_store_info r cross join tbl_site_store_format s;
RESULT
--------------------
R-AP-EAST-SMT-4567
R-NY-WEST-XYZ-4567
SQL>
Function returns a value; you didn't explain how it should look like (which parameters it accepts) so I chose to pass state, presuming it is unique within the table.
Sample data:
SQL> select * From tbl_rrsoc_store_info;
ST STOR ZON
-- ---- ---
AP EAST SMT
NY WEST XYZ
SQL> select * from tbl_site_store_format;
FORMAT_CODE
-----------
4567
Function:
SQL> create or replace function f_test (par_state in varchar2)
2 return varchar2
3 is
4 retval varchar2(18);
5 begin
6 select 'R' ||'-'|| r.state ||'-'|| r.store_code ||'-'|| r.zone_name ||'-'|| s.format_code
7 into retval
8 from tbl_rrsoc_store_info r cross join tbl_site_store_format s
9 where r.state = par_state;
10
11 return retval;
12 end;
13 /
Function created.
Testing:
SQL> select r.state, f_test(r.state) result
2 from tbl_rrsoc_store_info r;
ST RESULT
-- --------------------
AP R-AP-EAST-SMT-4567
NY R-NY-WEST-XYZ-4567

Create a PL/SQL block to insert a new record into the Department table. Fetch the maximum department id from the Department table and add 10 to it; take this value for department id; 'TESTING' is the value for department name and CHN-102 is the value for Location ID.
Note: Use '/' to terminate your query before compilation and evaluation
Table name : Department
Column name | Data type | Constraints
DEPARTMENT_ID | NUMBER(5) | PK
DEPARTMENT_NAME | VARCHAR2(25) | NOT NULL
LOCATION_ID | VARCHAR2(15)
Sample Output:
DEPARTMENT_ID DEPARTMENT_NAME LOCATION_ID
------------- --------------- -----------
XXXX TESTING CHN-102
The way you described it, it would look like this:
SQL> declare
2 l_department_id department.department_id%type;
3 l_department_name department.department_name%type := 'TESTING';
4 l_location_id department.location_id%type := 'CHN-102';
5 begin
6 select nvl(max(department_id), 10)
7 into l_department_id
8 from department;
9
10 insert into department (department_id, department_name, location_id)
11 values (l_department_id + 10, l_department_name, l_location_id);
12 end;
13 /
PL/SQL procedure successfully completed.
SQL> select * From department;
DEPARTMENT_ID DEPARTMENT_NAME LOCATION_I
------------- -------------------- ----------
20 TESTING CHN-102
SQL>
Note, though, that MAX + 10 is a wrong approach. If two (or more) users run the same procedure at the same time, only the first one who commits changes will be able to do that; other user(s) will violate the primary key constraint because that department_id already exists (as it was inserted moments ago by someone else). Use a sequence instead.
I have a column "Names" in the "Employee" table that has following values. The values either contain only single name (first, last, username) or Multiple names separated with semicolon (;). I need to search the values from that table either by first name or last name or username.
I have created a procedure but it is fetching only 1st,4th,5th records. Please let me know how to retrieve 2nd and 3rd records as well.
Firstname and lastname can be given by user with minimum of 2 characters length.
Username is given entire.
Employee:
ID Name Title
1 Andrea Warbutton (awr01) Manager
2 Claire Taylor (cta02);Mark Kites (mak03);Anitha Rooney (anr06) HOD;Supervisor;Business
3 Dave Rites (dar12);Jessica Simpson (jesi10) Lead;Analyst
4 Nick Ken (nik56) Product (Local,Regional)
5 Claire Pilkington (cpt09) Sales Owner
Code:
Create or replace empl (pm_firstname varchar2(100),
pm_lastname varchar2(100),
pm_username varchar2(100))
BEGIN
Select * from Employee
where Upper(Name) like Upper(pm_firstname ||'%'||) -- this will fetch 1st,4th,5th record
OR Upper(SUBSTR(Name, INSTR(Name),' '+1)) like Upper(pm_lastname ||'%'||) -- this will fetch 1st,4th,5th record
OR upper(REGEXP_SUBSTR(Name,'\((.+)\)',1,1,NULL,1)) = Upper(pm_username); -- -- this will fetch 1st,4th,5th record
END;
End empl ;
Please let me know how to retrieve 2nd and 3rd records as well.
Desired Output:
When searched with firstname = "Andrea", the output is below
ID Name Title
1 Andrea Warbutton (awr01) Manager
When searched with firstname = "Claire", the output is below
ID Name Title
2 Claire Taylor (cta02) HOD
5 Claire Pilkington (cpt09) Sales Owner
When searched with lastname = "Simps", the output is below
ID Name Title
3 Jessica Simpson (jesi10) Analyst
When searched with username = "mak03", the output is below
ID Name Title
2 Mark Kites (mak03) Supervisor
When searched with username = "nik56", the output is below
ID Name Title
4 Nick Ken (nik56) Product (Local,Regional)

Your task would be much easier if you normalize these data. Above query outputs:
ID FNAME LNAME UNAME
1 Andrea Warbutton awr01
2 Claire Taylor cta02
2 Mark Kites mak03
2 Anitha Rooney anr06
3 Dave Rites dar12
3 Jessica Simpson jesi10
4 Nick Ken nik56
5 Claire Pilkington cpt09
demo
Now you can search first, last, usernames however you want. First expression finds first word, then second and word between brackets.
Edit:
I posted the table structure with just ID and Name columns. However, I
have Titles column also in the same format separated with (semicolon).
In this case, How can I Normalize Titles as well along with Names
This query worked for provided examples:
with
x as (select id, name, '"'||replace(name, ';', '","')||'"' xmln,
'"'||replace(title, ';', '","')||'"' xmlt
from employee),
n1 as (select id, trim(xn.column_value) nm, rownum rn from x, xmltable(xmln) xn),
n2 as (select id, trim(xt.column_value) tt, rownum rn from x, xmltable(xmlt) xt)
select id, trim(regexp_substr(nm, '(\S*)(\s)')) fname,
trim(regexp_substr(nm, '(\S*)(\s)', 1, 2)) lname,
regexp_substr(nm, '\((.+)\)', 1, 1, NULL, 1) uname,
tt title
from n1 join n2 using (id, rn)
dbfiddle demo
Be careful however, because we cannot write ideal query. If you have entries like Benicio Del Toro, Mary Jo Catlett, Jean Claude Van Damme, it's impossible to write correct regexp. Sometimes second word is part of lastname, sometimes it is firstname, middlename etc.
The proper way is to modify table structure, divide rows, check results and put correct values in correct name columns. Now you have lists which are hard to search and every method may return wrong results.
No need for PL/SQL.

What does it do?
temp CTE splits semi-colon separated values into rows
final query uses a simple instr function which detects whether "rows" (extracted previously) contain value you're looking for
If it must be a function, that code can be reused. As you didn't say what exactly (which datatype, I mean) you want to return, I returned a string.

The problem is that each new department in ref_department corresponds to a new column in view/select query.
I've written below query:
variable DEPARTMENTS VARCHAR2(100)
BEGIN
:DEPARTMENTS :=NULL;
FOR cur_rec IN (SELECT DISTINCT DEPT_DESC FROM REF_DEPARTMENT) LOOP
:DEPARTMENTS := :DEPARTMENTS || ''''|| cur_rec.DEPT_DESC|| '''' || ',' ;
END LOOP;
dbms_output.put_line(rtrim(:DEPARTMENTS,','));
select * from
(select uid,uloc,uyear, depdesc, emp from
(select C.unit_id as uid, C.unit_loc as uloc,C.year as uyear, E.DEPT_ID as depid,R.DEPT_NAME as depname,R.DEPT_DESC as depdesc,S.NO_OF_EMP as emp
FROM Unit U INNER JOIN Employees E ON U.Unit_id=E.unit_id INNER JOIN REF_DEPARTMENT R ON E.DEPT_ID=R.DEPT_ID))
pivot
(min(emp) for depdesc in (:departments));
END;
error: PL/SQL: ORA-56901: non-constant expression is not allowed for pivot|unpivot
I've referred below links:
Pivoting rows into columns dynamically in Oracle;
http://www.orafaq.com/forum/t/187172/
Long ago (before Oracle's PIVOT queries existed) I wrote a blog post on "Pivot" Queries that gives you the code for a package to help construct such queries.
For your requirement you would do something like this:
declare
rc sys_refcursor;
begin
rc := pivot.pivot_cursor
( group_cols => 'u.unit_id, u.unit_loc'
, pivot_col => 'rd.dept_desc'
, tables => 'CompanyUnit x, Employees e, ref_departmnent rd'
, value_cols => 'e.no_of_emp'
, agg_types => 'sum'
, where_clause => 'e.dept_id = rd.dept_id and e.unit_id = c.unit_id'
);
end;
/
Since the ref cursor can have a variable number of columns you would need to use the DBMS_SQL package to parse it, find out the column names, and run it. The starting point would be to convert the ref cursor to a DBMS_SQL cursor:
n := dbms_sql.to_cursor_number(rc);
You'd need to refer to the DBMS_SQL package documentation example to take this further.
This question already has answers here:
Update rows in one table with data from another table based on one column in each being equal
(5 answers)
Closed 9 years ago.
i have table called Student with columns uniquename, age,department,city,Homecountry and another table called Employee with columns uniquename, exp,qualification, Homecountry.
now i want to update Student table's department column with Employee table's qualification column values under the where condition Student.uniquename = Employee.uniquename and Student.Homecountry = Employee.Homecountry.
please help me to write the update statement.
This kind of query is called a correlated sub query. For your requirement, the query would be as below....
update students s
set s.department = (
select e.qualification
from employee e
where s.uniquename = e.uniquename
and s.Homecountry = e.Homecountry
);
