Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ can be extended to handle specialized data types, access methods, routines, and other objects. HCL OneDB™ includes many built-in extensions that are fully integrated in the database server. HCL OneDB™ also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for HCL OneDB™.
Creating extensionsYou can create user-defined data types, routines, access methods, and other database objects to suit your needs. You can use application programming interfaces to write user-defined routines and applications that access data in HCL OneDB™ databases.
DataBlade® API Function ReferenceThe HCL OneDB™ DataBlade® API Function Reference describes the DataBlade® API functions and the subset of functions that the DataBlade® API supports.
Function descriptionsThis section gives comprehensive reference information about the functions that are valid within DataBlade® API modules. It lists the function descriptions in alphabetical order, with syntax, usage information, and return values for the functions.
The mi_library_version() functionThe mi_library_version() function returns the version and version date of the DataBlade® API currently being used.

The mi_library_version() function

The mi_library_version() function returns the version and version date of the DataBlade® API currently being used.

Syntax

mi_integer mi_library_version(buf, buflen)
   char *buf;
   mi_integer buflen;

buf: The user-allocated buffer for the version string.
buflen: The length of buf in bytes.


Valid in client LIBMI application?	Valid in user-defined routine?
Yes	Yes

Usage

The mi_library_version() function copies the version and version date into the user-defined buffer that buf references.

Server only: In a C UDR, mi_library_version() returns the name of the database server and its version number.

Beginning with HCL OneDB™ Version 10.0, use the new mi_server_library_version() function to obtain the correct database server version. The mi_library_version() function returns a string with the value "HCL OneDB Dynamic Server Version 9.50.UC1," which would still be applicable if your software uses string compare functionality.

Return values

MI_OK: The function was successful.
MI_ERROR: The function was not successful.
