You cannot create a DECODE function with both string and numeric return values. If you enter 'Halogen', the search does not find a matching value. ', 'Pythagoras', 1.414213562, When you run a mapping in high precision mode, if at least one result is Double, the datatype of the return value is Double. DECODE returns the default value of NONE for items 17 and 25 because the search values did not match the ITEM_ID. ', DECODE ( TRUE, ISNULL(ACCT_FIN#Acct_Key),'I', . [, default ] ) I have a doubt regarding Decode function.can u please clarify me. The search value must match the value argument. When you use DECODE, the datatype of the return value is always the same as the datatype of the result with the greatest precision. 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. This is, to say at least, puzzling and irritating. A decode function basically performs the task of CASE statements. The Decimal datatype has greater precision than Integer. 'Five', 5, In all cases, DECODE compares the first member of the pair against . For example, the following expression is invalid because the return values include both . 'Pi', 3.141592654). You cannot search for a portion of a value. The expressions when _ expr and then_expr are an expression pair, and you can specify any number of expression pairs in the DECODE function. For example, the following expression is invalid: DECODE (CONST_NAME The value you want to return if the search does not find a matching value. The attached workflow contains a sample mapping and workflow (for version . what is the difference Between TRUE and FALSE in the first argument here.How this works. 25 < 25 NO - that's what we are waiting for 'Archimedes', 3.141592654, 'NONE' ). Tags for Nested If in Informatica NULL if you omit the default argument and the search does not find a matching value. 'Variables were out of desired ranges. You can build an unlimited number of searches within a DECODE function. You might use DECODE in an expression that searches for a particular ITEM_ID and returns the ITEM_NAME: DECODE( ITEM_ID, 10, 'Flashlight', Example : Find the price of given item DECODE(item,'Pen',10,'Pencil',2,'Eraser',3,0) Example : Using decode as nested if DECODE(true,country='India','INR',country='US','DOLLAR',country='UK','GBP','DOLLAR') Tags for Decode - Value Search or Nested If Else in Informatica decode usage in infa how to use decode as nested if else decode in informatica Also, the search value is case sensitive.
