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 âORA-00939: too many arguments for the functionâ. You will need to create a formula that calculates a unit number for each of your ranges.ÄECODE(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.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.ÄECODE(TRUNC ((suppl_id - 1) / 10), 0, 'cat 1', Unfortunately, you cannot use the DECODE function for number ranges. 1-10 = âcategory 1â, 11-20 = âcategory 2â, 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.ÄECODE(SIGN(actual-target), -1, âNo bonuses for youâ, 0, âJust do itâ, 1, âCongratulations, you are the winnerâ) The example with the dates above can be modified as follows:ÄECODE(SIGN(date1-date2), 1, date2, date1) One of our readers suggested combining the SIGN function with the DECODE function as follows: The formula below is 0 if date1 is greater than date2: To do so, use the DECODE function as follows:ÄECODE((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. Request using DECODE is equivalent to the IF-THEN-ELSE design. You can use the DECODE function in an SQL query as follows: DECODE in the following versions of Oracle/PLSQL Oracle 12c, Oracle 11g, Oracle 10g, Oracle 9i Length of BLOB : 74018 The PDF/BLOB generated from Q2 does not open in a PDF viewer. If no match is found, DECODE will return NULL (if no match is found). Q2: select dbmslob.getlength (base64decode (base64encode (filedata))) from fndlobs where fileid - filedata contains binary BLOB data with content type application/pdf.If no matches are found, the DECODE function will return the default value.
