Logical operations in SQL decode function?

• SQL DECODE function

  Hi all
  
  I have the scenario where I have to post as below.
  
  VIEW: MILSTN_ACTUAL_DATE if the data shows ELSE use MILSTN_PSSTRGT_DTE
  

   SELECT
    T4.MILSTN_ACTUAL_DATE       LastMilestoneDate,
       FROM  DW_PROJECT        T1,
                DW_PROJ_H   T2,
          

  Hello

  This looks like a job for COALESCE:

  COALESCE ( TO_CHAR (milstn_actual_date, 'DD-Mon-YYYY')
        , TO_CHAR (milstn_psstrgt_dte, 'DD-Mon-YYYY')
        , 'NO MILESTONE REDCORDED
        )
  

  COALESCE returns the first argument not NULL.
  All arguments must have the same data type. Among the possibilities being a string ("No. MILESTONE REGISTERED'), which means the other arguments cannot be DATEs. you need to convert DATEs to strings.

  You can't find it confusing to use the DATE in a column, but DTE name in another? How do you remember whether or not you want to use an 'A'? You'll save yourself (and one who must maintain the code after you have) a lot of trouble if you deciide on a spelling and use cionsitently.

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

• How to switch OR logic in DECODE function?

  There is somewhere in my PL/SQL code as embedded in other SQL code. SELECT SUM (DECODE(COL1,'AB',COL2,'AC',COL2,'AD',COL2,'AF',COL2)) FROM DUAL you can see if COL1 is AB, AC, AD, or AF it returns COL2. I was worrying if it takes more execution time. Is there a better way to do this. We can pass the OR logical operator in DECODING so that all objects to check can be passed at any given time? I'm on Oracle 10 g.

  I'd not concerned that such internal function has a performance impact unless you have encountered a specific situation and have evidence to support.

  As others have shown, the other option to DECODE (which is specific Oracle) is to use the CASE (which is ANSI standard), and the CASE is also more flexible in terms of test conditions.

  Performance wise, however, there is little difference between the two.

• SQL Loader: Help TRIM and Decode functions please

  Hello
  
  I have load data from a flat file, for some columns, I need to use the TRIM and DECODE functions. It's a pipe delimited file.
  
  I get a syntax error (one is lower) same error listed for GARNISH.

  Can someone please help.
  
  Thank you
  Josiane

  Hello josiane.
  The error you receive leads me to believe that at some point before the DECODING on the BUSINESS_ID line, probably some line before the FINAL_BILL_DATE line, it is a syntactic error causing the quotes before DECODING actually put an end to some other syntaxes. Without any lines that might actually contribute to this, including details of the header, it's the best I can advise.

  Hope this helps,
  Luke

• Decode function in the Update statement

  Hi all
  
  I'm writing a query where I can update a pastdue_fees column in a table of book_trans based on a difference between the return_dte and due_dte columns.
  
  I use Oracle SQL. That's what I have so far for my decoding function:
  
  SQL > SELECT
  2 DECODE (SIGN ((return_dte-due_dte) * 2),)
  3 '-1 ', ' 0',
  4 '1', '12', 'Null')
  5 FROM book_trans;
  
  DECO
  ----
  Null value
  12
  Null value
  0
  
  If the logic is that, if the sign is - 1, the value in the return_dte column must be 0; If it is + 1, then it has 12 and everything else is Null.
  
  So now, I have to conclude my function of decoding of the update statement to update the columns. However, I get the error messages.
  
  The logic should be:
  UPDATE book_trans SET PastDue_fees = decode (expression)
  
  I gave him a few different tests with the following results:
  
  SQL > UPDATE book_trans
  2 SET pastdue_fees = SELECT
  3 DECODE (SIGN ((return_dte-due_dte) * 2),)
  4 '-1 ', ' 0',
  5 '1', '12', 'Null')
  6 FROM book_trans.

  6 FROM book_trans.

  If you really really really want to update the entire table, the syntax would be...

  UPDATE book_trans
     SET
        pastdue_fees  = DECODE(SIGN((return_dte - due_dte)*2), -1, 0, 1, 12, Null);
  

  I took out all the single quotes. If you actually have a string column and store all numbers in there so it must be reported as a NUMBER column and not a column of type character (varchar2).

  ALWAYS use the appropriate data type, it will save you a ton of headaches in the future.

• Logical operations on a string of bits

  Hi, I have a very simple question that I can't seem to understand.  I'd just like to perform logical operations (AND, GOLD, etc.) on 2 strings of bits that are 24 bits long each, however I can't find in the palette of functions a function that acts as a binary constant.  I see that constant digital and hex functions.  You can somone please let me know where I can find it.  For example, I would AND ' 111111111111111111111111 '& ' 000000000000000000000000'.

  You know the difference between numeric and string data types in LabVIEW? Blue = digital = integer. Pink = string. In the example you linked to, they use an integer constant when the display format is set to "binary". The 'b' of the constant indicates the radix, which in this case is 'binary '. Right-click on a digital constant and you can change its display format. You can select one of the predefined formats or you can specify a by clicking on the option "Advanced Editing Mode. Eligible formats are defined by using LabVIEW. For example

  %b = binary

  % 8 b = binary, using the width of minimum field of 8, fills spaces (for example, '1101')

  % 08 = binary, using 8 minimum field width, filled with zeros (for example, "00001101")

  Hello

  We can try like this...

  Begin
  : j: = 'CLERK ';
  end;
  /

  then, we execute your SQL query as below...

  Select the WORK, decode(:j,'CLERK','MANAGER','ANALYST','EXEC',JOB) OF the EMP
  where JOB =: j;

  I think that this will solve your problem

• Query SQL or function...

  Hi everyone,
  
  
    Please help me to clarify this question
  I have a "patient" table and a "address" table.And each patient has differnt types of addresses
  like PMI,Mailing and default address i need to pick patient address in the order of preference
  (PMI,Mailing ,Default)
  
  I have two options to get the address of a patient.Either write a SQL query to get the address of a 
  patient(according to preference)
  or write a function which checks
  
   if there is PMI,Mailing and default
    take PMI
   or
   If there is mailing and Default
   take mailing
   or
   take default.
  
  which one is the best method to get the address of a patient?  SQL query or function..
  Definitely everyone will say that it should be direct SQL query instead of multiple function calls.
  
  But in my organization there are many developers which will get "patient address" in their application 
  or SQL code or PL/SQL code or from some
  'X' Business intelligence tool.
  At this scenario is it best to have a function which every one will call and get a standardized output
   for every one.
  
  Question:
  
  In my scenario which one is the best to have "SQL query or function"?
  if i choose "function" i have to sacrifice the performance 
  if i choose "SQL query" i am not sure whether each and every developer querying the same way as it would be
  
  
  Sorry if it is a dumb question to ask.
  
  Thanks in advance
  phani

  hoek question: what happens if I have to choose between the SQL and function? (Assume that they do not accept to create views)

  If views are not accepted (which is very strange IMO), but you need some "standard object" which anyone can use, then you would choose to use a function instead of everyone having "their own motion.
  It is a compromise between maintaining standards and performance (call PL/SQL in SQL is generally to be avoided because of context switching, the other way around is OK).
  One of the advantages of a view: no problems with the settings you must enter but never going to use, you just choose the columns you need and there you go.
  Other: it is simple, plain and simple.
  It is easier to maintain.
  But everything depends on what your function returns.
  Maybe a REF CURSOR?

  Your question reminds me of this interesting discussion:

• String separated by commas to 'IN' operator in SQL query

  Hello

  The issue is that the "In" operator in the report query accepts values contained in the element of page Apex... 221,332,542.

  Is there a common solution for this problem?

  Thank you

  It's the common "variable list" model [anti-]. In

  select * from table where columnvalue in (7788, 7839, 7876)
  

  (7788, 7839, 7876)is a list of expressions and the predicate is evaluated as a membership condition.

  In

  select * from table where columnvalue in :P1_X
  

  :P1_Xis a scalar string, unable to contain multiple values.

  In a report of type APEX, a source report of the body of the PL/SQL function returning a SQL query with lexical substitution can be used to produce a "variable list:

  return 'select * from table where columnvalue in (' || :P1_X || ')';
  

  where P1_X contains less than 1000 values, has been disinfected to code SQL injectionand string values are properly cited.

  Some people suggest the following approach, that will work also in interactive APEX reports:

  select * from table where instr(':' || :P1_X || ':', ':' || columnvalue || ':') > 0
  

  However, it is underperforming because it eliminates the possibility of using the index optimizer or the size of the partition in the execution plan.

  See various elements in the list to ask Tom and imitating the channel to the table using sql features for effective solutions.
