  Ideally, you do not want to fix the application so that 'unwanted values' are not met initially in the table.

• UPDATE multiple columns with conditional parameters

  I have a procedure that updates several columns of a table using the parameter of the procedure. Is it possible to have a update unique with the parameter SET conditional statement?

  TERM NUMBER,
  TRANS_CD CHAR(2));
  
  INSERT INTO TEMP VALUES (1, '1 AUG 2009', 12, 'NB');

  INSERT INTO TEMP VALUES (3, '2 AUG 2009', 12, 'RN');

• [8i & 10g XE] How to compare a column with the text of a column with numbers

  This is probably a simple question, but I can't seem to find the answer. I tried variations on use to_number to_char and interpreters, all nothing will do.
  
  The real problem is that I have a table with a column of numbers in a database 8i (datatype = NUMBER (3)) and a column with the text (datatype = CHAR (3)), and I need to compare two values.
  
  This table has thousands of lines, but here's an example of the data in these two columns:

  TXT     CHR
  -----------
  001     1
  001     2
  002     2
  XXX     1
  003     3

  What I want to do is select the lines where the TXT and CHR VALUES do not match, then it would be (given my example):

  TXT     CHR
  -----------
  001     2
  XXX     1

  But, I'm having difficulties in comparing two columns, because they are not the same type of data.
  
  I tried to work on a simplified version of the problem in the 8i database both my 10g XE database:

  SELECT     *
  FROM     (
       SELECT     1.000               AS nbr
       ,     TO_CHAR(1.000,'000')     AS txt
       ,     CAST('001' AS CHAR(3))     AS chr
       FROM     dual
       )
  WHERE     txt = chr
  ;

  But this also returns any line, and it isn't even the "XXX" in the text column to treat in this example.
  
  Can someone help me understand what it is that I'm missing?
  
  Thank you!

  Simple if you know the secret; maddening if you do not have.

  ... I tried to work on a simplified version of the problem in the 8i database both my 10g XE database:

  SELECT     *
  FROM     (
       SELECT     1.000               AS nbr

       ,     CAST('001' AS CHAR(3))     AS chr
       FROM     dual
       )
  WHERE     txt = chr
  ;
  

  Try:

  TO_CHAR (1.000, 'FM000')
  

  By default, TO_CHAR leaves place the beginning of the string to a sign less, in which case he should ever one, TO_CHAR (1,000, '000') returns makes 4 characters, not 3. "FM" in the format said TO_CHAR do not add a space.

  If it does not, after the release of DUMP (txt) for the few lines that you can't match, so that we can see exactly what is in them.

• Columns with the same name but different data or precision length.

  DB version: 10 gr 2
  
  In a diagram, I need to find all of the columns with the same name but different or precision data length (if the column is of type number). I know I have to use the USER_TAB_COLS view for this. But I need to find a logic to compare the names of columns and its lengths.

  something like

  select t1.table_name
       , t1.column_name
       , t1.data_type
       , t1.data_length
       , t2.table_name
       , t2.column_name
       , t2.data_type
       , t2.data_length
    from user_tab_columns t1
       , user_tab_columns t2
   where t1.table_name != t2.table_name
     and t1.column_name = t2.column_name
     and t1.data_type = t2.data_type
     and t1.data_length != t2.data_length

• help me create a column with the time format

  Hi all
  
  Please help me find the query to create a table with 3 columns and insert the following data
  
  ENTITYID | CHGDATE | CHGTIME
  
  ======= ==================== ========
  
  4214984 | 2 OCTOBER 06 12.00.00.000000 AM | 07:23:57
  
  4214985 | 12.00.00.000000 11-SEP-08 AM | 10:52:19
  
  and update of the first line of the above table as follows
  ---------------------
  4214984 | 2 OCTOBER 06 07.23.57.000000 AM | 07:23:57
  ------------------------
  you will need to update the CHGDATE column with the time of the CHGTIME column.

  Sorry, we need a new format around the to_date

  select to_date(to_char(chgdate, 'mm/dd/yyyy') || ' ' || to_char(chgtime, 'hh24:mi:ss'), 'mm/dd/yyyy hh24:mi:ss') from etime3;
  

  This should telll Oracle to the format of the generated string. If this isn't the case, run select with the to_char two as separate columns to see that get us the data that we expect.

• Documentation about adding column with the DEFAULT value.

  Hello
  
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14200/statements_3001.htm#i2198241
  
  < quote >
  If you add a column, then the initial value of each row in the new column is NULL unless you specify the DEFAULT clause. In this case, Oracle database updates each row in the new column with the value specified for the DEFAULT value. This update operation, in turn, triggers AFTER UPDATE triggers defined on the table.
  < quote >
  
  I am not able to understand the emphasis on the part AFTER UPDATE while the column with DEFAULT values addition triggers both BEFORE and AFTER triggers defined on UPDATE.
  
  According to the documents of 11 g
  
  http://download.Oracle.com/docs/CD/B28359_01/server.111/b28286/statements_3001.htm#i2133105
  
  n.m. (u) r only changes with the NON NULL columns, but focus on AFTER UPDATE is still there. No trigger defined on the fire of the update in this case.
  
  This insistence is intended? If not, IMO, it should be changed.
  
  Kind regards

  Hi Sissi. After further discussion, we have added some information about a change in behavior. Here is what says the next version of the doc:

  When you add a column, the initial value of each row in the new column is null.

  * If you specify the DEFAULT clause for a column NOT NULL, then the default value is stored as metadata, but the column itself is not populated with data. However, the following queries that specify the new column are rewritten so that the default value is returned in the result set.

  This optimized behavior differs from earlier versions, when as part of operation ALTER TABLE Oracle database updated every line in the newly created with the default column and then fired defined update triggers on the table. In this release, no trigger is triggered because the default value is stored only in the form of metadata.

  * If you specify the DEFAULT for a nullable column clause, then the default value is added to existing lines under this ALTER TABLE statement, and any update triggers defined on the table are activated. This behavior also means if you change a NOT NULL column with a default value to be nullable.

  Hope that helps to clarify the matter further.

  Kind regards

• I have a column with two values, separated by a space, in each line. How to create 2 new columns with the first value in a column, and the second value in another column?

  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

• Querying the oracle table that has a column with the name of "FILE".

  Hi all

  I need to have an oracle table that has the column with the name "FILE".

  I can query all columns with the query "select * from table".

  This table is converted from ms access to oracle and I need to have this column with the name "FILE".

  Any suggestions?

  Hello

  FILE is a keyword from Oracle, so it's not a good name,

  Use FILEDATE, or DATE_FILED, or something else that is not in V$ RESERVED_WORDS. KEYWORD as the name column.

  If you need to use the FILE, then you must use quotation marks.
