One of our readers suggested using the LEAST function (instead of DECODE) as follows:An example with dates above can be modified as follows:LEAST(date1, date2)Question:I would like to know if it is possible to use the DECODE function for number ranges, i.e. 1-10 = ‘category 1’, ...
Helpful Tip: One of our viewers suggested combining theSIGN functionwith the DECODE function as follows: The date example above could be modified as follows: DECODE(SIGN(date1-date2), 1, date2, date1) The SIGN/DECODE combination is also helpful for numeric comparisons e.g. Sales Bonuses DE...

In this example, the DECODE function evaluates the job_code column, comparing it with the specified search values ('MGR', 'DEV', and 'HR'). If a match is found, the corresponding job title is returned. If there is no match, the function returns 'Unknown'. DECODE...
The OracleDECODE()function allows you to add the proceduralif-then-elselogic to the query. In the following example, the OracleDECODE()function compares the first argument (1) with the second argument (1). Because they are equal, the function returns the third argument which is the string'...
Implementing the DECODE() function with subqueries allows you to perform sophisticated conditional logic transformations to the data. The nested DECODE() statement in Oracle helps when we want to evaluate multiple conditions in a table. In the example below, we have used the nested DECODE() statem...
oracle max(decode用法 In Oracle, the MAX function can be used in combination with the DECODE function to return the maximum value from a set of different values based on specified conditions. The syntax for using MAX and DECODE together is: ``` SELECT MAX(DECODE(condition, value, expression...
Table 20-3 DECODE Function Parameters Returns At_token. Raises VALUE_ERROR: The input value is invalid. WWV_FLOW_CRYPTO.UNSUPPORTED_FUNCTION: The token is signed using an unsupported function. Example This example decodes an encoded token and print it's contents. ...
In a DECODE function, Oracle considers two nulls to be equivalent. If expr is null, then Oracle returns the result of the first search that is also null. The maximum number of components in the DECODE function, including expr, searches, results, and default, is 255. See Also: Data Ty...
If thedefaultvalue is omitted, this function returnsNULL. When thedefaultvalue is of theCHAR,VARCHAR2,NCHAR, orNVARCHAR2type, this function returns a value of theVARCHAR2type. Examples The following example uses theDECODEfunction to compare the values of5 × 3 - 2and3 × 4 - 1. ...
