Requirement – Getting rows from employee_details by using DECADE statement with ORDER BY clause. The DECODE function can be used in Oracle/PLSQL. Scenario – Getting rows from existing table by using DECADE statement with ORDER BY clause. The DESC command is used to sort the data returned in descending order. The query was as follows – SELECTīy executing above query we can get output like as follows - dept_id Requirement – Getting rows from employee_details by using DECADE statement. An index for a table can help improve searches and optimizations. ![]() Examplesįrom MariaDB 10.3.Scenario – Getting rows from existing table by using DECADE statement. Database SQL Language Reference DECODE Syntax Description of the illustration decode.gif Purpose DECODE compares expr to each search value one by one. The Decode function evaluates an expression to determine which criteria options are met and then performs an action (such as overriding a value) based on the evaluation results the function will perform these steps using a process that involves cases for different criteria. 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. User-friendly interface for data science. ![]() If it finds a match, the corresponding result expression is returned. SQL OnLine - Next gen SQL Editor: SQLite, MariaDB / MySQL, PostgreSQL, MS SQL Server. In Oracle mode from MariaDB 10.3.2, DECODE compares expr to the search expressions, in order. The resulting string will be the original string only if pass_str is the same. Create a function in SQL Server as below and replace the DECODE with dbo. DECODE compares the expression to each search value one by one. crypt_str should be a string returned from ENCODE(). In Oracle, DECODE function allows us to add procedural if-then-else logic to the query.
