Update a table using COUNT (*)

I was wondering if there is a way to write the following code uses a single stmt:

FOR update_rec IN ( SELECT CODE, COUNT(APPOINTMENT) TOT FROM TEST GROUP BY CODE )
LOOP
 UPDATE TEST
 SET TOT_APPOINTMENT = update_rec.TOT
  WHERE CODE = update_rec.CODE;
END LOOP;

Kind regards.

You can use what is called a statement update correlated . Note that this is not tested:

UPDATE test t1
SET    tot_appointment = ( SELECT COUNT(*)
                           FROM   test t2
                           WHERE  t1.code = t2.code
                         )
;

Problem with update of table (using the subquery to retrieve value)
Hello
I update a table based on the value of the subquery.
Here's the update statement.

UPDATING temp xm
SET xm.col1 = (SELECT DISTINCT col1

(SELECT col1, col2 COUNT (col2)
FROM table2
WHERE col1 = xm.col1
AND col2 = xm.col2
GROUP BY col1)
where col2 in (select... in the table3)
)
WHERE xm.col5 = < value >
AND xm.col6 = < value >

When I run this statement I get following error.
ORA-00904: "XM". "" Col1 ": invalid identifier.

Can someone help me why I get this error?
Why doesn't the main table alias in the subquery?

Is it possible to avoid this / re - write the query in a different way?

Thank you

You can nest only 1 level deep (referring to the table to be updated).

Have you looked at using the MERGE command? It is "easier" perform updates of this nature, assuming you are using a recent version of Oracle (9 or MORE).

Update the table using discoverer
Hello

I'm trying to update a table whenever the user runs a report of the Office of the discoverer. I tried to use a function to do the job, but I get the error below.

ORA-14551: cannot perform the DML operation within a query.

I also tried to
1. create a procedure and update the table in this procedure.
2. function to create and call the procedure created earlier in this function and use it in the discoverer, but still does not work and I get the same error ORA-14551.

Please let me know if this is possible at all the. If SO, let me know the steps to do so.

Thank you.
Hello

Yes you can update the discoverer dashboards using a PL/SQL function. You must make the function a standalone transaction. for example

FUNCTION update_record (key_field VARCHAR2) RETURN VARCHAR2
IS
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
..
UPDATE your_table
..
COMMIT;

and it gives me

ORA-04091: table DSAMSTRC.T is mutating, trigger/function may not see it
ORA-06512: at "DSAMSTRC.GET_T_ARRAY", line 6

My solution was to do a slider and update record row by row, but I was wondering if there is a way around this error?

Here's my example

DROP TABLE t;
------------------------------------------------------------------------------------

CREATE TABLE t
AS
       SELECT LEVEL id, 'A' txt
         FROM DUAL
   CONNECT BY LEVEL <= 10;

-------------------------------------------------------------------------------------

CREATE OR REPLACE TYPE t_table_type AS OBJECT
                  (id NUMBER, txt VARCHAR2 (200));
------------------------------------------------------------------------------------

CREATE OR REPLACE TYPE t_array AS TABLE OF t_table_type;
-----------------------------------------------------------------------------------

CREATE OR REPLACE FUNCTION get_t_array (v_txt IN t.txt%TYPE)
   RETURN t_array
   PIPELINED
IS
BEGIN
   FOR EACH IN (SELECT id, txt
                  FROM t
                 WHERE t.txt = v_txt)
   LOOP
      PIPE ROW (t_table_type (EACH.id, EACH.txt));
   END LOOP;

   RETURN;
END;
---------------------------------------------------------------------------------------

UPDATE t
   SET txt = 'B'
 WHERE id IN (SELECT id FROM TABLE (get_t_array ('A')));

You can create a global temporary table that has the same columns that use your function to insert in there, and then use it to update t.

CREATE GLOBAL TEMPORARY TABLE t_temp
(id    INTEGER,
 txt  VARCHAR2(100))
ON COMMIT DELETE ROWS;

INSERT INTO t_temp
  (SELECT id, txt FROM get_t_array('A'));

UPDATE t
   SET t.txt = (SELECT txt FROM t_temp
                 WHERE t_temp.id = t.id)
 WHERE t.id IN (SELECT id FROM t_temp);

update a table using a date to_char

Hello all;

I have the following query and the table below

create table t1
( 
       cid varchar2(200),
       yearid varchar2(200),
       begin_date date
       );

 insert into t1
           (cid, yearid, begin_date)
         values
           ('A', '2010_1', sysdate);
  insert into t1
           (cid, yearid, begin_date)
         values
           ('B', '2010_1', to_date('03/04/2011', 'MM/DD/YYYY'));
insert into t1
           (cid, yearid, begin_date)
         values
           ('C', '2010_1', to_date('01/02/2011', 'MM/DD/YYYY'));

and I have the following update statement

   update t1 t
       set t.yearid = '2011_1'
       where to_char(t.begin_date, 'YYYY') = substr(t.yearid, 1, 4);

what I'm trying is basically update table t1 yearid which is a varchar2 in to_char start the date are irregular... so in my case of the sample,

TO_CHAR date start back a 2011
Therefore, the yearid must be 2011_1 instead.

However, my udate statement does not work well

Don't know what exactly you want, but it looks like everything that you need is to change = to! = where year clause and using begin_date in update the value:

SQL> select * from t1;

CID YEARID     BEGIN_DAT
--- ---------- ---------
A   2010_1     26-JAN-11
B   2010_1     04-MAR-11

SQL> update t1 t
  2         set t.yearid = to_char(t.begin_date, 'YYYY') || '_1'
  3         where to_char(t.begin_date, 'YYYY') != substr(t.yearid, 1, 4);

3 rows updated.

Update of the data in the table using LAG/LEAD
Hello!

I have a table that looks like:

(
ACCOUNT_NUM VARCHAR2 (40 BYTE),

My question:
How can I configure end_dt (if null), to the next change_dt minus one

It shows what I want to do:

Select the rowid, account_num, phone, e-mail, start_dt, change_dt, end_dt, nvl (end_dt, lead (change_dt-1, 1) over (partition by account_num of start_dt order)) enddt CUSTOMER_INFO_TEST where end_dt is null;

So, I want to update the table itself with the date in enddt. But how do I do this?

This must be done in a single statement...

Thanks in advance

Normalize the names in a huge table using UTL_MATCH

Hello
I have a large table (350 million records) with a "full name" column
This column has a few typos, so I have to 'normalise' the data (only for this column), using UTL_MATCH. JARO_WINKLER_SIMILARITY.
I did some tests with a small table, and it works to show the similar names:
SELECT b.SID, b.name FROM typotable a, typotable b utl_match.jaro_winkler_similarity (b.SID, b.name) WHERE BETWEEN 85 and 99 AND a.rowid > b.rowid;

But:

(1) the test table was small, by using this code directly on the 350 million accounts table take ages... What can be done about it?

(2) this shows just the similar names. How can I update the table by searching for similarities, choose one of them as the only value for each name?

Thank you

1590733 wrote:

Yes, I get your point. The thing is that there is no "correct" available names and the original table is huge, that's what I thought:

-Create a table of secondary NAMES, with unique names. These names would have been generated by match the values similar to one of them (but always the same, no matter if is not one that suits). This should be equivalent to your table 'correctness '.

-Run the cleaning procedure for updating records

How can I create this secondary NAMES table? (The column 'genre' is not serious at all, that the 'name' must be set)

Thanks for your help

Well, you need to determine what is the logic that would pick one of the incorrect names on the other. In its current version, you can easily get two incorrect values having the same value of match. But then you must also consider what creates a 'group' of values that you can get the best in the group. Using the match itself is not enough to create groups.

Example:

SQL > ed

A written file afiedt.buf

1 Select a.fname as $fname1, b.fname as fname2

2, utl_match.jaro_winkler_similarity (a.fname, b.fname) as a match

3 typotable one

4 join typotable b on (a.fname! = b.fname)

where the 5 utl_match.jaro_winkler_similarity (a.fname, b.fname) > = 85

6 * 1.3 desc order

Programatically update af:table when clicking on createInsert af:button

Hi all
I use JDeveloper 11.1.2.4.0.
Requirement:
I have an af:panelCollection, inside I have a (Add) af:button and an af:table. Af: button creates an empty line in a table as createInsert. Now when I click on the Add button, it creates the empty line in the af: table. But the blank row is not visible immediately. It is visible only when I do another action in this page, as on some other tab and back.
From my observation, I found that the updating of the table does not occur immediately.
I want to create a blank line like createInsert done and immediately refresh the table so that the empty line is visible in the table.
I tried to adjust the partialTrigger of the tab; the reference to the id of the af: button, but still not working.
I tried to update the table in a pragmatic way during the click on the button, but did not work.
Can anyone suggest me solution for this.
Thank you and best regards,
Susanto
