This question already has an answer here:
How to use <br> tag in Dbms_output.put_line(''); in PL/SQL Oracle?
(1 answer)
Closed 3 months ago.
My query select apex_string.format('%s %s',empno,rpad(ename,5,' ')) as out from emp;
return below result 3 rows.
7839 KING
7698 BLAKE
7782 CLARK
Is it possible get result as single row some like this:
7839 KING
7698 BLAKE
7782 CLARK
Note: After 7839 KING new row in html that is < br / > tag...Is it possible in oracle sql query define new row?
Maybe all convert in clob? Result I want to export in TXT file.
Listagg with chr(10) (a line feed character), perhaps?
SQL> select listagg(empno ||' '|| rpad(ename, 7, ' '), chr(10)) within group (order by empno) as out
2 from emp
3 where deptno = 10;
OUT

I am new to Oracle programming (started coding a month ago).
I am doing a fuzzy-search, as follows:
WHERE SQL_text like '%VARIABLE%'
The problem is, VARIABLE is a cursor that iterates through a table that looks like this:
USA
UK
Japan
...
Could you please advise how to specify a variable in that WHERE clause?
I've tried the following, but it doesn't work:
WHERE SQL_text like '%'||VARIABLE||'%'
Thank you very much! I greatly appreciate everyone's input!
It works, if you use it correctly. I don't have your tables, but - I have Scott's emp so I'll search for jobs that contain certain substring.
Table contents:
SQL> select ename, job from emp order by job;
ENAME JOB
---------- ---------
SCOTT ANALYST --> 2 analysts
FORD ANALYST
MILLER CLERK --> 4 clerks

SMITH CLERK

I'm trying to figure out how I can output the results of a PL/SQL script to a results grid the same way results from a simple query are output. I'm new to Oracle from SQL Server, so I might be overlooking something very basic. For example how would I view the results of something like the following simple T-SQL (SQL Server's PL) script? Is there some sort of print_to_grid function? Or perhaps using a cursor? I know about dbms_output, but I definitely don't want to have to concatenate a string out of every script I want to see results from.
declare #emps table(employeeId int, name varchar(40)
insert into #emps
select employeeID, name
from employees
select * from #emps
This seems like it should be the simplest thing in the world, but I can't find a straight answer for it. Any help or tool recommendations would be greatly appreciated.
It sounds like you are after a ref cursor. For example
SQL> variable r refcursor
SQL>
SQL> begin
2 open :r for
3 select empno, ename
4 from scott.emp;
5 end;
6 /
PL/SQL procedure successfully completed.
SQL>
SQL> print r
EMPNO ENAME

7839 KING

At the point you open that refcursor, the result is pre-ordained - so there is no need to worry about read locks or data consistency etc. For example, I'll open the ref cursor when there is rows in the table, and then delete them...my printed data is still as it was at cursor open time.

I need an assistance with regard to building a PL/SQL block related to the following query:
SELECT <PRIMARY_KEY_COLUMN>, <VARCHAR_COLUMN> FROM TABLENAME WHERE REGEXP_LIKE(VARCHAR_COLUMN, UNISTR('[\D800-\DFFF]'));
The above query will give an output related to all the UTF8 bytes that are mentioned in the range.
I would request you guys to help me with modifying the above query, so that I can run it on all the VARCHAR/CLOB columns in the table and get an output like this:
ColumnName Value Primary_key_Column
-----------------------------------------------------------------------
Col1 v1 123
Col1 v2 124
.
.
Col2 v1 167
Col2 v2 123
.
.
Kindly review and please share your comments.
UPDATE1:
I was able to build the following block from the comments I received and from one of the posts, but it still requires edits:
set serveroutput on;
DECLARE
match_count integer;
v_search_string varchar2(4000) := 'shazamTemplateId';
BEGIN
FOR t IN (SELECT owner, table_name, column_name FROM all_tab_columns WHERE data_type in ('CHAR', 'VARCHAR2', 'NCHAR', 'NVARCHAR2', 'CLOB', 'NCLOB') AND table_name = 'DECORATION_FIELDS')
LOOP
BEGIN
EXECUTE IMMEDIATE
'SELECT COUNT(*) FROM ' || t.owner || '.' || t.table_name || ' WHERE REGEXP_LIKE( '||t.column_name||' = :1)'
INTO match_count
USING UNISTR('[\D800-\DFFF]');
IF match_count > 0 THEN
dbms_output.put_line( t.owner || '.' || t.table_name ||' '||t.column_name||' '||match_count );
END IF;
EXCEPTION
WHEN others THEN
dbms_output.put_line( 'Error encountered trying to read ' || t.column_name || ' from ' || t.owner || '.' || t.table_name );
END;
END LOOP;
END;
Here is a static solution (it does not require any PL/SQL code, but it require prior knowledge of the table and column names, and knowing which columns must be included). It also assumes all the "text" columns are VARCHAR2; as I explained in a Comment, you shouldn't expect to be able to return VARCHAR2 and CLOB values in the same column in the output. (Perhaps, if you must do everything in one go, you need several columns in the output: column_name but also column_type, as in VARCHAR2 vs CLOB, and then two value columns, one for VARCHAR2 columns in the original table and the other one for CLOB values.)
You can use something similar with PL/SQL code to make it dynamic; I don't recommend it.
So, anyway, here is the static solution. It uses the EMP table in the SCOTT schema. The PK is EMPNO (NUMBER data type), there are two VARCHAR2 columns, ENAME and JOB. EMP looks like this:
select * from emp;
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO

The query to solve your problem: (the query searches for values that contain the characters from V to Z; adapt to your needs)
select col_name, val, empno
from emp
unpivot ( val for col_name in (ename as 'ENAME', job as 'JOB') )
where regexp_like( val, '[V-Z]' )
order by col_name, empno -- If needed
;

I have written a query to execute the SP. The execution works fine with this. However, I'm not able to see output results.
declare v_rc sys_refcursor;
begin
SUSER.TRANS_REP (v_rc ,'Investments Series','31-12-2012','Dealer Group','All Adv') ;
end;
How to display output result with sys_refcursor. Please help.
note: I tried to print cursor but did not get any help. Also refered this (How to display a sys_refcursor data in TOAD's DataGrid and https://community.oracle.com/thread/627571), but still no help.
In SQL*Plus you could easily do it using a refcursor variable.
SQL> var r refcursor
SQL>
SQL> BEGIN
2 OPEN :r FOR SELECT empno,ename FROM emp;
3 END;

I guess in TOAD, you have some sort of output options. Select the variables you want to see the values in the output, the ref cursor result set would open in a different window.
I am new to Oracle. Is there a builtin keyword does the same job of SQL Server APPLY?
I think the equivalent of the APPLY clause in Oracle is called a lateral JOIN. A lateral join in Oracle is when you join a table A with a function F that outputs rows and this function has columns of A as parameters.
Let's build a small example with this setup:
SQL> CREATE OR REPLACE TYPE emp_row AS OBJECT (
2 empno NUMBER(4),
3 ename VARCHAR(10),
4 job VARCHAR(9),
5 deptno NUMBER(2)
6 );
7 /
Type created
SQL> CREATE OR REPLACE TYPE emp_tab AS TABLE OF emp_row;
2 /
Type created
SQL> CREATE OR REPLACE FUNCTION get_emp_dept(p_deptno NUMBER) RETURN emp_tab IS
2 l_result emp_tab;
3 BEGIN
4 SELECT emp_row(empno, ename, job, deptno)
5 BULK COLLECT INTO l_result
6 FROM emp
7 WHERE deptno = p_deptno;
8 RETURN l_result;
9 END get_emp_dept;
10 /
Function created
A lateral join is automatic in Oracle, there is no special keyword:
SQL> SELECT dept.dname, emp.empno, emp.ename, emp.job
2 FROM dept
3 CROSS JOIN TABLE(get_emp_dept(dept.deptno)) emp;
DNAME EMPNO ENAME JOB

In Oracle we can use a pipelined function in the FROM clause by using the TABLE() function.
SQL> select * from table( get_dept_emps (10) )
2 /
ENAME SAL MGR
------------------------------ ---------- ---------------------
BOEHMER 2450 SCHNEIDER
SCHNEIDER 5000
KISHORE 1300 BOEHMER
SQL>
This can be treated like any other table, for instance, by joining to it:
SQL> select t.*
2 , e.empno
3 from
4 table( get_dept_emps (10) ) t
5 join emp e
6 on e.ename = t.ename
7 /
ENAME SAL MGR EMPNO
---------- ---------- ---------- ----------

Since 12c, Oracle supports both APPLY and LATERAL natively: https://docs.oracle.com/database/121/NEWFT/chapter12101.htm#FEATURENO10330
