  Hello
  
  
  Im trying to convert varchar to date.

• help with quierying, a table with varchar as dates

  I have a table that the field is dataytped as varchar2, but she holds a date as such date of today '20100615'.

  "WHERE x BETWEEN y AND z" is equivalent to
  "WHERE x > = y AND x.<=>
  If y > z, no line will never be allowed, and if there is the great artist of value in your table, then lines (probably) very little, perhaps only 1 will satisfy the same if condition z > y.

  What exactly are you trying to do?
  It helps if post you a small example of data (CREATE TABLE and INSERT statements) and the results desired from these data. If the results are conditional, give some examples, for example, "if I run the query at any time on 15 June, I want to... but if it's June 16, so I want to..." »

  If you want the most recent 15 days, including today (that is, when run on 15 June, you want from 1 June until 15 June) then:

  SELECT DISTINCT
       fwvitals_date
  FROM      fwvitals
  WHERE       fwvitals_date     BETWEEN     TO_CHAR (SYSDATE - 14, 'YYYYMMDD')
                 AND     TO_CHAR (SYSDATE,      'YYYYMMDD')
  ;
  

  Fortunately, the strings are in a format such as sorting is explicit, so you don't have to run TO_DATE on each of them and get conversion errors.

• Import SQL Developer data change column entire varchar data type

  Hi all
  
  May I ask, how do to change all the data type of columns using a single click? I want to import a csv file that has more columns then 200. When I use SQL Developer to impoprt it to the Oracle database, there is the possibility to change the data type of the columns, but it is posibble only on a column-by-column. How can I do this with just a click of mouse? In the csv file, there are only numbers, not alphabetic or other characters. But SQL Developer sets automaticully VarChar for all columns when importing the csv file. And if the data type of the columns is of type varChar, the data mining model produced only 10% of predictive confidence. If the columns integer (number), the trust is more than 80%. I use about 50 tables, and each table has more than 200 columns, so changing the data type of columns by a something inhuman is ::(((

  Can someone help me?
  
  Thank you!!!

  You can send the generated here script? I just want to see the DDL Create of the Table and some examples of INSERT statements.

  To remove the rows in the Table, you can run this in the worksheet:

  DELETE

  ;
  COMMIT;

  You can run the Create Table DDL (skip all INSERT queries) to create the table. Then, use the Import Wizard to import data in this table (column all should have correct data types). In the Import Wizard, you can specify the Table to import the data.

• Query a date in a varchar field

  I'm doing a simple query...

  Count the number of records in a given month.

  I use variables in the URL and use this query (MSSQL)

  
  SELECT recorddate FROM sometable
  WHERE Year (recorddate) AS ' #Url.year # '.
  AND Month (recorddate) AS ' #Url.month # '.

  It should work in theory, I think, but the problem is that the date field is of type varchar (although all records have a time stamp that has been added as:)

  < INPUT type = "hidden" name = "recordate" value = "#Now () #" >

  I'm not advanced in ColdFusion, so I hope someone can help me... Is there a simple way to do this?

  Thank you!

  I agree with Dan Bracuk you need to store your date values in a date column.  It would be for SQL server DATETIME, SMALLDATETIME, or DATE depending on your version of the server and the requirements.

  As a quick fix, you can use a derived table that converts your varchar in date column values.  Note that this must be used as a work around until you can update your table to use a date column.  This request will probably not run well on large data sets.  You must also use the CFQUERYPARAM tag to avoid SQL injection vulnerabilities.

  
  
      SELECT recorddate
       FROM
       (
           SELECT CONVERT(DATETIME, recorddate) AS recorddate
           FROM sometable

  You can use to_date and to_char in combination to get the required format:

  select to_char(to_date(latest_completion_date,'YYYYMMDD'),'DD-MON-RR') latest_completion_date

  If you are using PL/SQL, to get the results in the exact format you need should be easy.

  Using only SQL, you can get the acc_no on a separate line using GROUP BY GROUPING SETS.  You can use CASES and the GROUPING function to show only the acc_no on some lines and all, but acc_no on others.  May also get the acc_no and the trn_dt in the same column.  (You will need to explicitly call TO_CHAR for this).

  GROUP BY GROUPING SETS can also get a header line after the first acc_no.  If the VARCHAR2 headers are part of the result set, you will need to convert to strings, the total NUMBER of columns using TO_CHAR.

  Maybe some of you have done proof of formatting is not important to you.

• Date range search

  Hello
  Filtering data for a specific date range does not give the desired result. Currently, the column is a column varchar2.

  Then under query should display the records only 2 for the range of data between 01/01/2013, but his displays all records. Please notify.

  Sample data:

  
  create table Records_test (B_Recorded_Date VARCHAR2 (4000 BYTE))

  insert into Records_test values('12/04/2013');
  insert into Records_test values('7/25/2000');
  insert into Records_test values('10/30/2003');
  insert into Records_test values('9/5/2006');
  insert into Records_test values('12/5/1994');
  insert into Records_test values('12/19/2013');
  insert into Records_test values('9/4/1992');
  insert into Records_test values('8/7/2007');
  insert into Records_test values('9/28/2005');
  insert into Records_test values('12/10/2004');
  insert into Records_test values('11/28/2011');

  Select * from Records_test
  where

  10/12/2004
  28/11/2011

  Thank you.

  Hello user7988

  Try this:

  SELECT *.

  OF Records_test

  WHERE

  TO_date (substr (B_Recorded_Date, 0, 10), ' MM/DD/YYYY') > = TO_DATE('07/01/2013','MM/DD/YYYY')

  AND TO_date (substr (B_Recorded_Date, 0, 10), ' MM/DD/YYYY')<>

  ;

  The best way if you set this column as DATE, then there is no need to convert your varchar value date.

• Worker name/back and after a return both before course start date?

  Hi all
  
  Could someone help me with the below please?
  
  I have a query that back the worker assigned to a child just before where equal to the date the child begins his training course (see below). It works very well.
  

  select *
   from
  (
  select tc.childid, 
  tc.childname, 
  tc.enteredcourse, 
  tw.workername, 
  tw.allocatedstartdate, 
  row_number() over ( partition by tc.childid, tc.enteredcourse order by tw.allocatedstartdate desc) rn
  from tableofchildren tc, tableofworkers tw
  where tc.childid = tw.childid(+)
  and tc.enteredcourse >= tw.allocatedstartdate(+)
  )
  where rn = 1 

  However, I disocvered that not all children have a worker who they are assigned before / the day they began their courses (mainly because of the poor quality of the data, but a few good reasons why). Therefore, I need to write a report to audit history of children and worker participation including the following columns:
  
  The worker at a time that the child started the course (CurrDate/CurrWorker),
  The worker who began working with the child more recently to the child from any watercourse (PAWDate/PAWorker).
  The worker who began working with the child more recently after the child from any watercourse (POWDate/POWorker).
  The worker who works with the child before their course (LastDate/LastWorker)
  And how long the worker who works with the child before the end of their course was working with the child (LastWorkerLen)
  These would just return null when it is not subject to conditions.
  
  I'm not sure what the best approach is to do this.
  
  I thought I could use Min/Max, which I think should work correctly for columns to date... but it won't work for the text (workername) columns. This is because it will match the name of the worker according to the min/max value of the string, as a min/max value, will sometimes differ from the min/max value of the back and is not directly linked to the beginning dates dates/end through a relational code.
  
  Can anyone recommend a better/more sustainable approach to the code below?
  
  Thanks a lot for reading. Maketables below - output 1 is the desired result. :)
  

  select tc.childid, 
  tc.childname, 
  tc.enteredcourse,

  Hello

  Looks like you already know how to get information about paw and pow separately.
  The curr and information on the latter is actually more simple: just look for work that has been active on the date of enteredcourse or leftcourse.
  Collect all 4 items is the trickiest part. Do an outer join of tableofchildren with each of the 4 separate result sets. Conditions corresponding to your 'rn = 1"must be part of the join condition, as information may be absent for a child.

  WITH     curr     AS
  (
       SELECT     c_curr.childid
       ,     w_curr.allocatedstartdate     AS currworkerdate

• Problem with SQL report to modify data

  Hi all
  
  I don't know that I'm writing this question in the right page or not. But my question is: I have a column in my table which is of type varchar. Data in this column are as Fallows:
  
  257414/45y
  194662223445 8877/j7tg
  .....
  I wanted to know, is anyway I can show this data in my report without any / or - fallow:
  
  25741445y
  1946622234458877j7tg
  
  Just for your information, this is a sql report.
  
  Thank you

  I read your question because how do you remove both the ' / ' and '-' characters. If true do as follows:

  Select REPLACE(REPLACE('194662223445-8877/j7tg','/'),'-','') from DUAL
  

  At the end of the statement where ") of the DOUBLE appears, these two single quote characters have no space between them. That means replace NULL for the characters you want to replace.

  You can test the statement leaving from DOUBLE. Once satisfied, change it to 'from MyTable '.

  I don't know what to tell you on the TTITLE. It of what I used and always works to print a title.

• Return max date records before the start date

  Hello
  
  Can anyone help please?
  
  I have two subqueries, a tableofchildren called, the other called tableofworkers. Tableofchildren identifies the date the child started a class.
  
  The second query, Tableofworkers, lists the workers and their history of involvement with the child. A child may have had a history with several workers. The worker has an allocatedstartdate indicating when they began to work with the child.
  
  For my purpose, I need to return the workername and the allocatedstartdate of the worker involved with the child more recently before or at the time when the child began the course.
  
  I have partially accomplished this with the query below. However, due to the quality of the data, the child may not always have an affected worker (allocatedstartdate) earlier or equal to the start date for the course of the child. In this case, the query fails and does not return the child record, that it excludes from the dataset.
  
  Can anyone suggest a way to modify this query, so it acts like a left outer query and returns all the records in the child and null raising where they have no worker allocated beginning before or on the date of start of course?
  
  Thank you! :)

  What something like that?

  SELECT childid
       , childname
       , enteredcourse
       , workername
       , allocatedstartdate
  FROM
  (
       SELECT toc.childid
            , toc.childname
            , toc.enteredcourse
            , tow.workername
            , tow.allocatedstartdate
            , ROW_NUMBER() OVER (PARTITION BY toc.childid ORDER BY tow.allocatedstartdate DESC) AS rn
       FROM   tableofchildren   toc
       LEFT JOIN tableofworkers tow ON tow.childid = toc.childid
                       AND toc.enteredcourse >= tow.allocatedstartdate
  )
  WHERE rn = 1
  

  Just note that you need a different RANK and DENSE_RANK analytical ranking function if there is a chance that many workers could be attributed to the children on the same allocatedstartdate.

• Variable Date format of presentation

  Hi all try to format a variable presentation from a Narrative perspective, is it possible that this can be done by using javascript or html that I can stick in narrative mode.
  
  I want something like ' the date used is @{indate} to the end of the month.
  
  Date format must also be JJ.mm.aaaa... his currenty displayed as yyyy/mm/dd... I don't want to add the columns in my report and hide as there seems to be a performance lag when I do this.
  
  Any ideas... Java gurus out there.
  
  I tried @{indate} [dd.mm.yyyy..] but it does not work.
  
  See you soon

  Here you go...

  I tried in my machine and its working very well...

  In the answers--> in the criteria TAB, in the column fx use under formula...

  «case when 1 = 1 then EVALUATE ('TO_CHAR(%1,%2)' as a varchar (20), date ' @{pv_date} {1998-07-05} ',' dd.mm.yyyy "") else ' ORE time Dim ".» End of the name of the month.

  pv_date is the variable of presentation and

  For "ore time Sun. "" MNTH name ' use any column of varchar data type ...

  Hope that's helpful...

  Thank you

• data differences

  RDBMS: 10.2 standard
  
  Hello
  I have two tables with the same definition.
  table-a
  Identification number
  name varchar
  created_date date
  
  table-b
  Identification number
  name varchar
  created_date date
  
  table b is imported from another schema. Now the two same weakening, but table-b may have some documents that might not exist in a table. I can't tell apart them by id id maybe even. Second thing, is date, date stores only date but not timestamp. In general, is not seems to extract the differences.
  
  I want to know that it is something inserted by Oracle RDBMS (as if oracle is maintaining some timestamp internally with each insert on the table, etc.) to find the differences in this case?

  Don't leave not but

  Select * from table_b
  minus
  Select * from table_a
  

• Conversion of date format?

  Hello
  
  I have a collar (varchar) with values like 2010-02-23 12:42:31 I want to convert varchar to date MM-DD-YYYY format

  You can use TO_DATE and TO_CHAR:

  SQL> SELECT TO_CHAR(TO_DATE('2010-02-23 12:42:31','YYYY-MM-DD HH24:MI:SS'),'MM-DD-YYYY') AS NEW_DT FROM DUAL;
  
  NEW_DT
  ----------
  02-23-2010
  

  However, you should seriously consider converting these VARCHAR columns that store dates in the DATE data types.
