If it's a positive number p is greater than 100. So try to subtract 100 from p and check whether it's a positive number or not. In Oracle, you can use DECODE function to evaluate a list of expressions, and if a value is matched return the corresponding result. But if you can transform it into an arithmetic operation resulting into an integer value you got what you want. It is possible to use DECODE, but you'd have to use nested DECODEs and you'd end up with something that's much harder to read, understand and therefore maintain. 1 If I am not wrong you can't use boolean like that. They can transform a value into another value.
Miracle173, thank you for clarifying, I am using ORACLE SQL, For this particular script, I am not using SQL PLUS, just firing off a script (f5 in TOAD) and.

select 1 value1,Ĭase when 'a' = 'a' and 'b' = 'b' then 'pass' In Oracle SQL, Should You Use CASE, DECODE, or COALESCE The Oracle functions CASE, DECODE, and COALESCE all perform similar functionality. 1 DECODE is a SQL function, not a PL/SQL function.
Oracle plsql decode pdf#
Length of BLOB : 74018 The PDF/BLOB generated from Q2 does not open in a PDF viewer.
The simplest answer is don't use decode, use a case statement instead, e.g. Q2: select dbmslob.getlength (base64decode (base64encode (filedata))) from fndlobs where fileid
