![]() If expr is null, then Oracle returns the result of the first search that is also null. If no matches are found, the default expression is returned, or NULL if no default is provided.ĭECODE_ORACLE is a synonym for the Oracle-mode version of the function, and is available in all modes. In a DECODE function, Oracle considers two nulls to be equivalent. If it finds a match, the corresponding result expression is returned. In Oracle mode from MariaDB 10.3.2, DECODE compares expr to the search expressions, in order. I assume this occurs because, as the names suggest, DECODE is a function and. Using Oracle's Data Type Summary, DECODE is returning a VARCHAR2 (data type 1) whereas the CASE statements are 'returning' numbers (data type 2). The resulting string will be the original string only if pass_str is the same. You can see that the data type of the DECODE is 1, whereas the two CASE statements 'return' a data type of 2. crypt_str should be a string returned from ENCODE(). In the default mode, DECODE decrypts the encrypted string crypt_str using pass_str as the In all modes from MariaDB 10.3.2: DECODE_ORACLE(expr, search_expr, result_expr ) This includes, search and result arguments.In Oracle mode from MariaDB 10.3.2: DECODE(expr, search_expr, result_expr ) ![]() 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 “ORA-00939: too many arguments for the function”. You will need to create a formula that calculates a unit number for each of your ranges.ĭECODE(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:
