the query will run on every 10 min,and if any of the status not changed . 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. Thank you all. The value you want to return if the search finds a matching value. It occurs due to issues with 'infa_decode' UDF function in 'Spark' mode, which was returning 'NULL' values as output. previous_toolbox_user.

AlanWms Member Posts: 368 Nov 30, 2012 10:05AM Syntax DECODE ( value , first_search For Example: IF CollegeCode = 10 - 11, THEN <blank> (leave empty) IF CollegeCode = 12, THEN "A". You can use the case statement in 8.1.7 onwards. You cannot search for a portion of a value. If you use DECODE to search for a value in a string port, you can either trim trailing blanks with the RTRIM function or include the blanks in the search string. If the function finds the value, it returns a result value, which you define. 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 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. I think I understand what you are looking for. Any value with the same datatype as the value argument. The encountered issue is a bug in Informatica 10.2.2 or later versions, before 10.2.1 HF1 SP1. Syntax DECODE ( value , first_search , Thanks for the information on decode doesn't support relational operator. This means it is likely to be easier for future developers to work with. Hello Everyone, I am totally new to informatica. DECODE function in Standard Query Language (SQL) is used to add procedural IF - THEN - ELSE like statements to a query. Does anyone know if we can have multiple conditions in decode function or is there any other function to achieve this? You can build an unlimited number of searches within a DECODE function. 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. Solution. Computers can ping it but cannot connect to it. You can enter any valid expression. DECODE is more efficient than using the IIF function in PowerCenter. This expression always writes the result as a Decimal. The following expression tests multiple columns and conditions, evaluated in a top to bottom order for . Decode syntax for multiple nested conditions Hi, I have the following scenario,and I want to use nested Decode function .Kindly let me know how to solve this problem.. Does anyone know how to make the link blue with PeopleCode? You cannot create a DECODE function with both string and numeric return values. 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. Searches a column for a value that you specify. If the function finds the value, it returns a result value, which you define. You can enter any valid expression. In the following example, the Oracle DECODE () function compares the first argument (1) with the second argument (1). You can build an unlimited number of searches within a DECODE function. 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. The Decimal datatype has greater precision than Integer. The value you want to return if the search does not find a matching value. Any value with the same datatype as the value argument. If at least one result is Double, the datatype of the return value is Double. You can enter any valid expression. The Oracle DECODE () function allows you to add the procedural if-then-else logic to the query. Tasks that are hard using DECODE are easy using CASE. Is there a reason that it has to be a DECODE rather than a CASE? The following expression tests multiple columns and conditions, evaluated in a top to bottom order for TRUE or FALSE. Passes the values for which you want to search. The following expression tests multiple columns and conditions, evaluated in a top to bottom order for TRUE or FALSE.

Any datatype except Binary. The Decimal datatype has greater precision than Integer. The DECODE will stop evaluating as soon as a condition is true. I made the following assumptions about the thresholds since you did not give a complete set: Software in Silicon (Sample Code & Resources). You're describing something to do with checking an interval of elapsed time, but the post title is "Multiple condition check using decode". 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 ) 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. NULL if you omit the default argument and the search does not find a matching value. IF CollegeCode = 13 - 16, THEN "B". CASE was introduced with version 8, and DECODE was around before then. The attached ZIP contains: 1. Your daily dose of tech news, in brief. This expression always writes the result as a Decimal. Any datatype except Binary. CASE offers more flexibility than DECODE.

Let's see the following example: SELECT DECODE ( 1, 1, 'Equal' ); Code language: SQL (Structured Query Language) (sql) In this example, the DECODE () function compares the first argument (one) with the second argument (also one). It compares a given expression with each search value one by one and returns a result on the basis of outcomes received from the comparison. SELECT * FROM t. WHERE (sysdate-modifieddate)* 24 * 60 > DECODE (status, 1, 3, 2, 5, 3, 7, 4, 10) HTH. Also, the search value is case sensitive. Default value if the search does not find a matching value. . Why do you need to use DECODE? Cloud Application Integration provides built-in function util:base64Decode which can be used to decode a Base64 encoded the string. We can use multiple decodes for nested conditions quite, What is standard practice for storing documents in Oracle database. 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. What do you want to do? if order_type is 01 then revenue will be multipled by 2 and if it is 03 then it will be not considered in target and for others as it . You can enter any valid expression. the first condition that is true) determines the value that is returned, if none of the conditions is met the last parameter is returned. If you enter 'Halogen', the search does not find a matching value. You can build an unlimited number of searches within a DECODE function. Also, the search value is case sensitive. For example, you have the following expression: The return values in this expression are 5, 1.414213562, and 3.141592654. Passes the values you want to search. If the function finds the value, it returns a result value, which you define. Any datatype except Binary. Try something like this (not sure if it will work though): I guess the code Gary gave should be fine. When you use DECODE, the datatype of the return value is always the same as the datatype of the result with the greatest precision. Also, DECODE returns NONE for the NULL ITEM_ID. Searches a column for a value that you specify. The value you want to return if the search finds a matching value. If you enter 'Halogen', the search does not find a matching value. It is possible to to range tests and in lists using decode, but it gets really ugly really quickly. Any datatype except Binary. Any datatype except Binary. For example, you have the following expression: The return values in this expression are 5, 1.414213562, and 3.141592654. Nested iif using decode statement is preferred over multiple iif statments. 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.
