For example, you have the following expression: The return values in this expression are 5, 1.414213562, and 3.141592654. The Decimal datatype has greater precision than Integer. NULL if you omit the default argument and the search does not find a matching value. You can enter any valid expression. This means it is likely to be easier for future developers to work with. NULL if you omit the default argument and the search does not find a matching value. If you enter 'Halogen', the search does not find a matching value. AlanWms Member Posts: 368 Nov 30, 2012 10:05AM or if u need that only in the decode statement then, I need to write decode for multipe columns for example. It may or may not be faster, that depends.

If the function finds the value, it returns a result value, which you define. You can enter any valid expression. You're describing something to do with checking an interval of elapsed time, but the post title is "Multiple condition check using decode". Searches a column for a value that you specify. Any datatype except Binary. If you use DECODE to search for a value in a string column, you can either trim trailing blanks with the RTRIM function or include the blanks in the search string. DECODE is an older function. My requirement is to return a value based on more than one column. If Name = ABC and Age = 10 and School = XYZ and Grade = JKL and City = PQR and Nationality = DEF / GHI/ LMO/QRS , then column JJJ = 'zxceswdth' PowerCenter Like Answer Share If the function finds the value, it returns a result value, which you define. You can enter any valid expression. Depending on the requirements, either: use one IIF statement connecting all your conditions with AND use DECODE function if only one of the conditions will be met (it lets you avoid the nested IIFs) Share Follow answered Nov 30, 2021 at 7:05 Maciejg 2,797 1 17 29 Add a comment Your Answer Post Your Answer DECODE function in Standard Query Language (SQL) is used to add procedural IF - THEN - ELSE like statements to a query. Every 10 minutes, you want to run a query to identify the records that have stayed in one status longer than the allowed threshold. You can use decode to test out multiple conditions like CASE WHEN. If you use DECODE to search for a value in a string column, you can either trim trailing blanks with the RTRIM function or include the blanks in the search string. Syntax DECODE ( value , first_search You can build an unlimited number of searches within a DECODE function. You can use the case statement in 8.1.7 onwards. Decode - Value Search or Nested If Else in Informatica Forget Code Informatica Decode - Value Search or Nested If Else Decode function searches ports for a specified value, it can also be used as Nested if Else function DECODE( value, first_search, first_result [, second_search, second_result ] [, default ] ) Example : Find the price of given item You can build an unlimited number of searches within a DECODE function. Passes the values for which you want to search. A record can remain in status 1 for no more than 3 minutes, in status 2 for no more than 5 minutes, in status 3 form no more than 7 minutes, in status 4 for no more than 10 minutes, and in status 5 forever/.

Computers can ping it but cannot connect to it. IF CollegeCode = 13 - 16, THEN "B". For example, you have the following expression: The return values in this expression are 5, 1.414213562, and 3.141592654. The following expression tests multiple columns and conditions, evaluated in a top to bottom order for . I do not want to check if a column is null or not. You can build an unlimited number of searches within a DECODE function. If the function finds the value, it returns a result value, which you define. If at least one result is Double, the datatype of the return value is Double. You can build an unlimited number of searches within a DECODE function. Syntax DECODE ( value , first_search , Does anyone know how to make the link blue with PeopleCode? Also, the search value is case sensitive. For example, if you want to search for the string 'Halogen Flashlight' in a particular column, you must enter 'Halogen Flashlight, not just 'Halogen'. Example The following example checks for null values in the items table: ISNULL ( ITEM_NAME ) ISNULL and Complex Data Types You can use ISNULL to check whether an array or a struct has a null value. Cloud Application Integration provides built-in function util:base64Decode which can be used to decode a Base64 encoded the string. Any datatype except Binary. What do you want to do? Decode will return when the first match is found, so the ordering is important. Thank you all. DECODE ( TRUE, Employee in ('210','220','230') and substr (Score,1,1) = '7', concat (substr (Employee,1,2),'2') , Employee in ('210','220','230') and substr (Score,1,1) <>'7',concat (substr (Employee,1,2),'1'), Employee ) Tasks that are hard using DECODE are easy using CASE. I think I understand what you are looking for. The following table describes the argument for this command: Return Value TRUE (1) if the value is NULL. Nested iif using decode statement is preferred over multiple iif statments. Syntax DECODE ( value , first_search , previous_toolbox_user. If Name = ABC and Age = 10 and School = XYZ and Grade = JKL and City = PQR and Nationality = DEF / GHI/ LMO/QRS , then column JJJ = 'zxceswdth' PowerCenter Like Answer Share Any value with the same datatype as the value argument. Default value if the search does not find a matching value. DECODE is more efficient than using the IIF function in PowerCenter.

You can enter any valid expression. Yes, I know that case works for me, But I want to use DECODE in a tool. You cannot search for a portion of a value. If the data contains multibyte characters and the DECODE expression compares string data, the return value depends on the code page of the Secure Agent that runs the task. If you enter 'Halogen', the search does not find a matching value. Also, the search value is case sensitive. I made the following assumptions about the thresholds since you did not give a complete set: Software in Silicon (Sample Code & Resources). FALSE (0) if the value is not NULL. CASE was introduced with version 8, and DECODE was around before then. The search value must match the value argument. Welcome to the Snap! The encountered issue is a bug in Informatica 10.2.2 or later versions, before 10.2.1 HF1 SP1. What tool are you using that allows DECODE but not CASE?

This topic has been locked by an administrator and is no longer open for commenting. The attached ZIP contains: 1. Could anyone help me to write below IF statements in Expression Transformation. For example, the following expression is invalid because the return values include both string and numeric values: You might use DECODE in an expression that searches for a particular ITEM_ID and returns the ITEM_NAME: DECODE returns the default value of NONE for items 17 and 25 because the search values did not match the ITEM_ID. This is a decode equivalent of the case solution others have already shown. Does anyone know if we can have multiple conditions in decode function or is there any other function to achieve this?
