Here is a simple sqlplus line command with & substitution run time variable.
set verify off; SQL> SELECT * FROM emp where sal >&SAL; Enter value for sal:
Now as you see, oracle asks to Enter Value for substitution variable in line just below the SQL>. I wonder if there is one or more line could be left there so to improve the readability. So it should look like:
set verify off; SQL> SELECT * FROM emp where sal >&SAL;
Declare a variable called sal to store the salary of an employee. In the executable part of the program, do the following:
a.Store an employee name in a substitution variable. b.Store his or her salary in a variable. c.If the salary is less than 5,000, give the employee a 10% raise and display the message "<Employee Name> salary updated" in the window. d.If the salary is more Last Name Message than or equal to 3,000, print the employee's salary in the format, "<Employee Name> earns ............. No raise is given."
So the result should ask for the last name
- Himuro and message should show [Himuro's salary updated] - Greenberg [Greenberg earns 12000. No raise is given.] - Patel [Patel's salary updated]
Here is my PL/SQL
set serveroutput on
DECLARE v_emp_sal employees.salary%type; v_emp_last_name employees.last_name%type; BEGIN v_emp_last_name :=initcap('&emplastname'); SELECT salary INTO v_emp_sal [code]......
question: How can I get the apostrophe in the dbms_output.put_line. Attached is the create employees table code.
Is there a way to have a variable in the FROM clause or another way to have the table name as a variable? I'm trying to not repeat the same query three times with only the table name being different.
---the tables
create table org_a (emp_id number(5) not null, name varchar2(20)); create table org_b (emp_id number(5) not null, name varchar2(20)); create table org_c (emp_id number(5) not null, name varchar2(20));
---the records
INSERT ALL INTO org_a (emp_id, name) VALUES (00001, 'MISTER WHITE') INTO org_a (emp_id, name) VALUES (00002, 'MISTER ORANGE') INTO org_b (emp_id, name) VALUES (00003, 'MISTER PINK') INTO org_b (emp_id, name) VALUES (00004, 'MISTER BROWN') INTO org_c (emp_id, name) VALUES (00005, 'MISTER BLUE') INTO org_c (emp_id, name) VALUES (00006, 'MISTER BLOND') SELECT * FROM dual;
---verify inserts
SELECT * FROM org_a UNION ALL SELECT * FROM org_b UNION ALL SELECT * FROM org_c;
---i want the table name to be dependent on a variable. eventually, ---i intend to link v_org to a form with radio buttons (values: 1, 2, 3) ---to keep this simple, i'll just assign 1 to v_org
DECLARE
v_org number(1) := 1; v_table varchar2(5);
BEGIN v_table := CASE v_org WHEN 1 THEN 'org_a' WHEN 2 THEN 'org_b' WHEN 3 THEN 'org_c' END;
SELECT * FROM v_table;
END;
--this is what i receive

I have created a list with name Test_List and 5 values in it.
I want to pass the values dynamically when i select the list values (any of the 5 values).
I tried:
For each list setting(List Details --> Static list entries --> Target) i have set the Request as ?Test_List=#Test_List# Note: Here Test_List is my list name.
I have a exp .dmp file of a database that has over 1000 tables. I would like to import all tables that don't begin with 'C'. Is this possible with IMP (without listing each table I want)?
>select level ,empno,ename,mgr from emp connect by prior empno=mgr start with mgr is null;
Output:- > LEVEL EMPNO ENAME MGR ----- ---------- ---------- ---------- 1 7839 KING 2 7566 JONES 7839 3 7788 SCOTT 7566 4 7876 ADAMS 7788 3 7902 FORD 7566 2 7698 BLAKE 7839 3 7499 ALLEN 7698 3 7521 WARD 7698 3 7654 MARTIN 7698 3 7844 TURNER 7698 3 7900 JAMES 7698

Note:- I got only this that this query is alternative of self join and it is giving manager name along with mgr id for each employee but when it gives output i couldn't able to understand how to identify who is manager of whom. Tell and explain with clause in oracle , i only know it is alternative of inline view but i want to know how does it work and how to use 'WITH' in oracle query if possible.
This time, I am going to provide the DML statements.
I have a simple table with 3 fields in it.I want to group by ACCT_NUMBER and sum of BALANCE field. But I want to get the description of the first row in a group.
the statements below. Here there are two groups of records 2001 and 2002. My sql(which I am working on) should return the following :
2001 EMPL TRAINING-MIS 20 2002 OTHER PROF SERV-HR 40
The following query will group by ACCT_NUMBER and sum of the BALANCE field. But how can I get the DESCRIPTION?
SELECT ACCT_NUMBER, SUM(BALANCE) FROM TEST GROUP BY ACCT_NUMBER CREATE TABLE "TEST" ("ACCT_NUMBER" VARCHAR2(20 BYTE), "DESCRIPTION" VARCHAR2(20 BYTE),
I am getting error 'ORA-03113: end-of-file on communication channel' in Oracle 11g R2 version when I ran the below query.
WITH tab1 AS (SELECT C_NUM as col1 FROM test123_v) SELECT COUNT (distinct col1) num_assignments FROM tab1 UNION ALL SELECT COUNT (distinct col1) num_assignments FROM tab1
The same query is working fine in 10g.Here test123_v is view created using table test123, which has one column c_num.When I use the table instead of view in the with clause I am getting the output in 11g. The below query gives the output.
WITH tab1 AS (SELECT C_NUM as col1 FROM test123) SELECT COUNT (distinct col1) num_assignments FROM tab1 UNION ALL SELECT COUNT (distinct col1) num_assignments FROM tab1
I have a small doubt...Without any creation of tables as I feel it's not needed...(let me know if u need them) Error says "Missing Keyword"
select distinct record_number from meta m, procedu b, control v, fact f, calendar dc, person p where f.key = m.key and f.group_key = b.group_key and b.proc_key = v.proc_key and f.calendar_key = dc.calendar_key and f.person_key = p.person_key and VALUE BETWEEN DECODE((Select distinct operator_type [code]....
But this gives an error...If the decode gives a "single"...the statement is working fine...but If the decode gives a "range"...the above statement gives an error saying "missing keyword"..Does the above code when mapped to "Range"...is it not producing "and" like " value between 100 and 1000"
I have requirement to create an XML structure through stored procedure. I need to Order some of the columns in ascending order before I format them into the xml structure. I am pretty novice to creating an output into XML format, but attached is the query I came up with (without order by). This works perfect, but now the requirement is to order by - cls_cd, and within cls_cd, again order by - cat_cd. I am not able to do this.
You think i can do a from clause with conditions ??
The reason is that i need to retrieve fields from different schemas depending on a column in a common table
let s say the column CRITERIA_COL is in table Common If COMMON.CRITERIA_COL has value 1 then the select query should fetch results from the schema : SCHEMA1.MY_TABLE If COMMON.CRITERIA_COL has value 2 then the select query should fetch results from the schema : SCHEMA2.MY_TABLE If COMMON.CRITERIA_COL has value 3 then the select query should fetch results from the schema : SCHEMA3.MY_TABLE
Something like this:
Select my_Col1, my_Col2 from (case COMMON.CRITERIA when '1' then SCHEMA1.MY_TABLE when '2' then SCHEMA2.MY_TABLE when '3' then SCHEMA3.MY_TABLE )
but that is not working .By the way my query is not just that, it s a more complicated query, that s just the portion I am having trouble with .
I am not strong in SQL but can write easy SQL for data extraction but seem to not understand how to correctly use sysdate in a where clause.
Case: I have to create an alert that will email my IT dept once a person is terminated in Oracle HR. The alert will only run once a day with all terminations specified in the alert. Setting up the alert is not the issue, but rather the SQL code I want to use.
The alert will run everyday at CoB 17:30. Now, in my query, how do i specify that the results should be only for the current day? The problem however, is that I also retrieve Person Type which should show as Ex-Employee, but this is only shown the day after the actual termination has been done, because the employee is still active on the date of termination.
It is the simplest join or inner. An equijoin combines rows that have equivalent values for the specified columns.
SQL> select * from x;
NAME EMAIL EMPID Sam email@removed 1060 Rose email@removed 1061
[code]....
don't consider above mentioned queries I got valuable outputs.
NAMEEMAIL EMPID NAME EMAIL EMPID samemail@removed 1060 sam email@removed 1060 roseemail@removed 1061 rose email@removed 1061 sonaemail@removed 1062 sona email@removed 1062
Inner join shows matches only when they exist in both tables.so , i got records 1060,1061,1062
// Referencing columns used in a USING clause. SQL> select x.name,x.email,x.empid from x 2 inner join y 3 using (empid);
select x.name,x.email,x.empid from x * ERROR at line 1: ORA-25154: column part of USING clause cannot have qualifier
so query rewritten as
SQL> select x.name,x.email,empid from x 2 inner join y 3 using (empid); NAME EMAIL EMPID --------------- --------------- ---------- sam email@removed 1060 rose email@removed 1061 chris email@removed 1062
I mean see two different outputs.first output records twice displayed ... Yes i agree that is Inner join.second output records not displayed twice... common records only displayed once ,in x and y.
I think should n't use a table name or alias when referencing columns used in a USING clause... am i right ????
I want to know both are inner joins .how Oracle is determined both outputs ?
SELECT sno,mid,mname FROM manage_date WHERE mname IN ('KIRAN-KUMAR', 'RAHUL-RAJ', 'KAUSHAL-SONI');
IF I use this query directly in DB it's working fine. But when this query is calling in .net using parameter as below it's not giving any records for more than one value. IN (:p_mname)
If I pass one name 'KIRAN-KUMAR' from .net It's working.
If I pass multiple names from .net query not returning any records.
SELECT * FROM wc_claims WHERE part_nbr in l_part_nbr ;
I have three tables: table A has - user_id, supplier table B has - supplier, part_nbr table C , wc_claims, has part_nbr and 78 other columns.
what i need to do is when user logs in with his user_id, he should see only that info from table C, corresponding to his supplier, and the part_nbr.
SELECT supplier from table_A WHERE user_id = 'abc' ; supp_abc SELECT distinct part_nbr from table_B WHERE supplier = 'supp_abc' ; partA, partB, partC,........partZZ
SELECT * FROM wc_claims WHERE part_nbr in (partA, partB, partC,........partZZ );
I have created a function :
create or replace Function wcl_partnbr ( p_supp IN varchar2 ) RETURN CLOB IS
[Code].....
so that I can use that in the WHERE clause, because one supplier can have thousands of parts...so it works fine, if there are 200 part numbers for one supplier, but above that.. it doesnt.
EXAM2@orcl> desc search_table; Name Null?

In a dotnet application user is going to input/select all/any of the above column in where clause.If user has given value for rol column then ref cursor should be :
select * from search_table where rol like <given value> endif and/or
If user has given value for cnm column then ref cursor should be :
select * from search_table where rol like <given value> and/or cnm like <given value> endif
I mean whatever value is being given; it should be part of where clause.For it i am going to :
EXAM2@orcl> CREATE OR REPLACE PACKAGE rollsearch AS 2 TYPE t_cursor IS REF CURSOR; 3 Procedure rol_cursor(c_rol in varchar2,c_cnm in varchar2,c_fnm in varchar2, 4 c_mnm in varchar2,d_dob in date,n_year in number,c_exam in varchar2,c_main_supp in varchar2, 5 io_cursor IN OUT t_cursor); 6 END rollsearch; 7 /
EXAM2@orcl> CREATE OR REPLACE PACKAGE BODY rollsearch AS 2 Procedure rol_cursor(c_rol in varchar2,c_cnm in varchar2,c_fnm in varchar2, 3 c_mnm in varchar2,d_dob in date,n_year in number,c_exam in varchar2,c_main_supp in varchar2, 4 io_cursor IN OUT t_cursor) 5 IS 6 v_cursor t_cursor; 7 sql varchar2(1000); 8 BEGIN 9
What should i write further; so that i may get ref cursor as whereed clause for given value. So that i may populate my datagrid view for that web form.
