Hello
Here is an example of a VARCHAR2 variable usage in PL/SQL.
VARIABLE dj REFCURSOR
CREATE OR REPLACE FUNCTION dept_by_job
RETURN SYS_REFCURSOR
IS
-- dept_by_job returns a SYS_REFCURSOR that has
-- one row for every department in scott.emp and one
-- column for every job, showing the number of employees
-- in that department with that job.
return_csr SYS_REFCURSOR;
select_txt VARCHAR2 (5000);
BEGIN
-- 1st part of query is fixed
select_txt := 'SELECT deptno ';
-- 2nd part of query depends on what's in the table
FOR r IN ( SELECT DISTINCT job
FROM scott.emp
ORDER BY job
)
LOOP
select_txt := select_txt || ', COUNT (CASE WHEN job = '''
|| r.job
|| ''' THEN 1 END) AS '
|| r.job
|| '_cnt ';
END LOOP;
-- Last part of query is fixed
select_txt := select_txt || ' FROM scott.emp'
|| ' GROUP BY deptno'
|| ' ORDER BY deptno';
OPEN return_csr
FOR select_txt;
RETURN return_csr;
END dept_by_job
;
/
SHOW ERRORS
EXEC :dj := dept_by_job;
PRINT :dj
Otherwise, as you have provided a test table, here's an example suitable for your test table:
CREATE OR REPLACE FUNCTION pivot_rv
RETURN SYS_REFCURSOR
IS
return_csr SYS_REFCURSOR;
select_txt VARCHAR2 (5000);
BEGIN
-- 1st part of query is fixed
select_txt := 'SELECT ';
-- 2nd part of query depends on what's in the table
FOR r IN ( SELECT DISTINCT field_name
, ROW_NUMBER () OVER (ORDER BY id) AS rnum
FROM render_values
ORDER BY rnum
)
LOOP
select_txt := select_txt || CASE
WHEN r.rnum > 1
THEN ','
END
|| 'MAX (CASE WHEN field_name = '''
|| r.field_name
|| ''' THEN field_value END) AS "'
|| r.field_name
|| '"';
END LOOP;
-- Last part of query is fixed
select_txt := select_txt || ' FROM render_values';
OPEN return_csr
FOR select_txt;
RETURN return_csr;
END pivot_rv

SQL Analysis: Extract column expression and SQL query tags
Hi all
I have a requirement and posted earlier reg. this.
An SQL statement must be parsed and column names must be extracted separately.
I can't use dbms_sql. I need to extract the names of columns through manipulating strings in PL/SQL only.
I don't have to validate the SQL code.
for example.
SELECT EMPNO, Upper (ENAME), DEPTNO Emp_Name, DECODE (Deptno, 10, 'ACCOUNTING', 20, 'HR', 'OTHER') Dept_Name OF double
Output should be,.
Column names
--------------------
(1) EMPNO
(2) Emp_Name Upper (ENAME)
(3) DEPTNO
(4) Dept_Name DECODE(Deptno,10,'ACCOUNTING', 20,'HR','OTHERS')
How can I retrieve the names of columns using PL/SQL for the above format?
Pls help.
Kind regards

Each line in a column to an XML conversion
Hello world
With the help of Oracle Database 10 g Enterprise Edition Release 10.2.0.4.0 - 64 bit
I have a table where there is a comments column which is VARCHAR2. This column contains data of type string in the form of XML tags.
As for example. * < tag_name attr_name = "10" / > * (cant sorry give the exact values that I'm not allowed to)
There are as many such lines. Now, I want to use these channels and operated as a XML like the use of XPath to find some attributes etc.
I tried to use the extract function and to use it, I need an XMLType object. So I tried to create one using the XMLType() constructor.
But it gives me error ORA-19032: tag expected, XML had no content
When I looked on the net, I found that this error number does not match the error message I get. The msg of error found on internet, it is should tag XML string as string
I used this query
But when I changed (based on the intuition of someone)SELECT XMLType (<column>) FROM <table>;
The application worked well. That it may take only one line.SELECT XMLType (<column>) FROM <table> WHERE ROWNUM <= 1;
I also tried like this
This worked too well.SELECT XMLType ('<tag_name attr_name="10"/>') FROM DUAL;
So finally he left me completely confused. Is there a way to convert every row in a column to an XMLType object so that I can use the extract function to collect information on this topic.
For now, I used REGEXes to write code. However, with the flexibility of xml is preferable.
Any help would be appreciated.
Kind regards

Published by: aalami Kanrar on May 23, 2013 05:27Aalami,
The error message is correct. What you have found, it is simply the generic message with placeholders in the string .
The error message is also pretty explicit: you cannot pass an empty string (NULL) to the XMLType constructor.
SQL> select xmltype('') from dual; ERROR: ORA-19032: Expected XML tag , got no content ORA-06512: at "SYS.XMLTYPE", line 310 ORA-06512: at line 1 no rows selectedYou must either add a WHERE clause to filter the columns NULL or use a CASE statement to only convert strings that are not empty:
SELECT XMLType () FROM WHERE
IS NOT NULL ; SELECT CASE WHENIS NOT NULL THEN XMLType ( ) END FROM ... And do not use EXTRACT if you want access to scalar values, use EXTRACTVALUE instead:
SQL> select extractvalue(xmltype(''), '/tag_name/@attr_name') from dual; EXTRACTVALUE(XMLTYPE(' update of each line in a column
I have to update only the first letter of all the names in the last_name column used table... Please help me with this issue?You must be more precise, that is what you need:
update mytable set last_name = 'A' || Substr(Last_name,2);that's really interesting.

- Hello
I post this question for clarification. I have a report that is based on a SQL query area.
Place automatically APEX sql in the tables, all THE results of a query if it is in a region of report? Or y at - it a step that the developer must do to retrieve the columns of the sql query in a table.
I'm working with checkboxes, and I read up on top of the api APEX_APPLICATION. This part is still unclear.
Your comments would be appreciated!
KeishaHi Keisha,
You should have a read of: [http://download-uk.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28839/check_box.htm#CHDHFACG] that explains the use of checkboxes on the reports.
I guess the 'picture' you refer to are APEX_APPLICATION. G_F01 up APEX_APPLICATION. Paintings of G_F50? If so, they are built when you submit the page and are based on elements with attributes of 'name' of 'f01' up to 'f50' in the HTML tags. You don't need to do anything beforehand to create these, which is done automatically for you by the Apex. But, notes, however, that only the checked boxes are presented with a page - so if your username is checked, say, 3 of the 10 boxes, table will contain only 3 points not 10 (with each element of the table that contains the attribute 'value' of a checkbox).

Is possible to write the INSERT statement that fills two columns: 'word' and 'sense' of the file text with multiple lines - in each line is followed word that is the meaning?
Hello

Of course, it is possible. According to what the text file looks like to, you can create an external table that treats the text file as if it were a table. Otherwise, you can always read the file in PL/SQL, using the utl_file package and INSERT of PL/SQL commands.
You have problems whatever you wantt? If so, your zip code and explain what the problem is.
Whenever you have any questions, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the exact results you want from these data, so that people who want to help you can recreate the problem and test their ideas. In this case, also post a small sample of the text involved file.
If you ask about a DML operation, such as INSERT, then INSERT statements, you post should show what looks like the tables before the DML, and the results will be the content of the table changed after the DML.
Explain, using specific examples, how you get these results from these data.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).

I have a column with two values, separated by a space, in each line. How do I create 2 new columns with the first value in one column and the second value in another column?
Add two new columns after than the original with space separated values column.
Select cell B1 and type (or copy and paste it here) the formula:
= IF (Len (a1) > 0, LEFT (A1, FIND ("", A1) −1), ' ')
shortcut for this is:
B1 = if (Len (a1) > 0, LEFT (A1, FIND ("", A1) −1), ' ')
C1 = if (Len (a1) > 0, Member SUBSTITUTE (A1, B1 & "", ""), "")
or
the formula of the C1 could also be:
= IF (Len (a1) > 0, RIGHT (A1, LEN (A1) −FIND ("", A1)), "")
Select cells B1 and C1, copy
Select cells B1 at the end of the C column, paste

1. I dono how simply we can convert rows to columns
2. for root = 1683691, there are double NAM and RAC in lonet table... ideally these data should not be there, but since its here, we can take a MAX so that it returns a value
3. There are undesirables who should be ignored
Once again my thought process is that we join the activity and 4 alias table lonet.

Hello
This is called pivoting.
Here's a way to do it:
WITH relevant_data AS
(
SELECT a.project_wid, a.project_no, b.SID
, l.name AS lonet_name, l.entryvalue
Activity one
LEFT OUTER JOIN lonet l.root = a.project_wid l
)
SELECT *.
OF relevant_data
PIVOT (MAX (entryvalue)
FOR lonet_name IN ("GAC" IN the gac
"NAM" AS nam
'BAG' IN the bag
"RAC" AS cars
)
)
ORDER BY project_wid
;
Output:
PROJECT_WID PROJECT_NO GAC NAM BAG RAC NAME

How to access a column value in a Select list in a tabular presentation for each line
Hello
Environment: Using Oracle APEX v4.2.1 on an Oracle 11 g 2 DB
In a tabular presentation using the following example query, i.e.:
select "EMPNO", "EMPNO" EMPNO_DISPLAY, "ENAME", "HIREDATE", "SAL", "DEPTNO", "MY_LOV" from"#OWNER#"."EMP"
I need access to every line of my sub form of table, the EMPNO of this line value, within a list of selection (query based LOV) in the column "MY_LOV."
So, basically, the MY_LOV column in my table presentation, would be a list of selection (query based LOV) where MY_EMPNO =: EMPNO (first column in the select statement above), for each line of the tabular presentation.
With the help of a picture ( Tom's Blog ) and assuming 'Deptno' column here is actually my new column, i.e. "MY_LOV, I want to know how this list of selection based on lov query would be able to access each EMPNO down in the form of tables, i.e. 7839, 7698, 7782 etc.?
Any help would be appreciated.
Thank you.
Tony.

each line has a type and a rasthaus id to it. ID belongs to other parent tables. the value of each type is given, and the validity of each value is followed by a field start_date and end_date.
All values start from 1 - JUN and expires on 31 - AUG. Now my requirement is to obtain a report that gives three columns for three different types (ALLOW, ADTAX and MXTAX) with combination of unique values in the effective time interval. Let me put the result below.

ZTR0098 | 8. 45. 6. 23 JUL | 31 AUG |
As you can see there are no duplicate rows for a combination of (ALLOW, ADTAX and MXTAX) with their respective dates in force. resulting in the above table. the first step is to convert lines to the column which is pretty obvious to do that by grouping on start_date and end_date colum, but the real deal is the time interval during which the combination of the values (ALLOW, ADTAX, and MXTAX) has remained constant.
I wrote under query using Group by.

SQL query to retrieve a single record for each employee of the following table?
Hi all
Help me on the writing of SQL query to retrieve a single record for each employee of the following table? preferably a standard SQL.
CREATE TABLE xxc_contact)
empnum NUMBER,
alternatecontact VARCHAR2 (100),
relationship VARCHAR2 (10),
phtype VARCHAR2 (10),
Phone NUMBER
);
insert into xxc_contact values (123456, 'Rick Grimes', 'SP', 'Cell', 9999999999)
insert into xxc_contact values (123456, 'Rick Grimes', 'SP', 'Work', 8888888888)
insert into xxc_contact values (123457, 'Daryl Dixon', 'EN', 'Work', 7777777777)
insert into xxc_contact values (123457, 'Daryl Dixon', 'EN', 'Home', 3333333333)
insert into xxc_contact values (123456, 'Maggie Greene', 'CH', 'Cell', 9999999999)
insert into xxc_contact values (123456, 'Maggie Greene', 'CH', 'Home', 9999999999)
expected result:
EmpNum AlternateContact Relationship PhType Phone
123456 rick Grimes SP cell 9999999999
Daryl Dixon EN work 7777777777 123457
Home 123458 Maggie Greene CH 6666666666
Thanks in advance.

Specifically, the two simple solutions provided were:
1 using the row_number, entitled Oracle ranking based on descending order of the inside telephone each empnum group. And finally selects the lines which has least rank (of least since that order is descending for phone).
SQL > column alternatecontact format A20;
SQL >
SQL > SELECT empnum, alternatecontact, relationship, phtype, phone
2 from (SELECT a.*, row_number() over r (PARTITION BY empnum ORDER BY phone / / DESC))
3 FROM xxc_contact one)
4. WHEN r = 1
/
EMPNUM ALTERNATECONTACT RELATIONSHIP PHTYPE PHONE
---------- -------------------- ---------- ---------- ----------

2. with the help of MAX, Oracle automatically assigns the maximum phone for all the rows in each group of empnum. And finally selects the rows with the maximum phone. Order by clause is omitted here intentionally. You can find out why.
SQL > SELECT empnum, alternatecontact, relationship, phtype, phone
2 (SELECT a.*, MAX (phone) over (PARTITION BY empnum) rn FROM xxc_contact one)
3 WHERE phone = rn
4.
EMPNUM ALTERNATECONTACT RELATIONSHIP PHTYPE PHONE
---------- -------------------- ---------- ---------- ----------

Daryl Dixon EN work 7777777777 123457
