A stored procedures(PSM, Persistent Stored Modules) of ALTIBASE HDB might be divided into three as below.

  • Stored Procedure: With input, output and input/output parameters, A user can execute SQL statement with a predefined procedures inside a procedure by using it. It doesn't return a value and delivers a value to the client through output and input/output parameters.

Basic syntax of Procedures the procedures used in OracleORACLE's PL/SQL is almost same with  Altibase Stored Procedures, So you  can easily convert Oracle Procedure to Altibase Procedure  except for some function which is not supported in Altibase.Altibase Stored Procedures with  ALTIBASE Stored Procedure,

So you can easily convert the ORACLE PL/SQL to the ALTIBASE Stored Procedure except for some functions which are not supported in the ALTIBASE HDB.

We call these ALTIBASE Stored Procedure to the ALTIBASE PSM ( Persistent Stored Modules) with a different name.
