This includes, search and result arguments. Yes, the maximum number of components that you can have in a DECODE function is 255. Is there a limit on the number of arguments that you can specify in one DECODE operator? I get the error message “ORA-00939: too many arguments for the function”. You will need to create a formula that calculates a unit number for each of your ranges.ĭECODE(TRUNC ((yrs_of_service + 3) / 4), 0, 0.04, If yrs_of_service = 1 and 5, then return 0.06 I need to write a DECODE request that will return the following: The formula will be evaluated at 2 if suppl_id is between 21 and 30.The formula will be evaluated as 1 if suppl_id is between 11 and 20.The formula will score 0 if suppl_id is between 1 and 10. 1,231 5 21 43 10 Nobodys mentioned it in the answers (yet), but you should never decrypt passwords.However, you can try to create a formula that will define one number for one range and another number for another range, and so on.ĭECODE(TRUNC ((suppl_id - 1) / 10), 0, 'cat 1', Unfortunately, you cannot use the DECODE function for number ranges. 1-10 = ‘category 1’, 11-20 = ‘category 2’, instead of decoding each number individually. I would like to know if it is possible to use the DECODE function for number ranges, i.e. One of our readers suggested using the LEAST function (instead of DECODE) as follows:Īn example with dates above can be modified as follows: The combination of SIGN / DECODE is also useful for digital comparisons such as bonus sales.ĭECODE(SIGN(actual-target), -1, ‘No bonuses for you’, 0, ‘Just do it’, 1, ‘Congratulations, you are the winner’) The example with the dates above can be modified as follows:ĭECODE(SIGN(date1-date2), 1, date2, date1) One of our readers suggested combining the SIGN function with the DECODE function as follows: I am working with Oracle Forms 10g pl / sql. I just want to show I do not want to keep it, and do not know how to decode base64 then display it on an item image. The formula below is 0 if date1 is greater than date2: The image is base64 encoded and sent as a String and I am trying to do is to decode and display it on an item image. To do so, use the DECODE function as follows:ĭECODE((date1 - date2) - ABS(date1 - date2), 0, date2, date1) Otherwise, the DECODE function should return date1. One of our readers wanted to know how to use the DECODE function to compare two dates (that is: date1 and date2), where date1 > date2, the DECODE function should return date2. The DECODE function will compare each suppl_id value, one after the other. Read more MongoDB profiler and database performance problem diagnosis and identification
