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_binary_to_date() functionThe mi_binary_to_date() function creates a text (string) representation of a date from the internal (binary) DATE representation.

The mi_binary_to_date() function

The mi_binary_to_date() function creates a text (string) representation of a date from the internal (binary) DATE representation.

Syntax

mi_lvarchar *mi_binary_to_date(date_data)
   mi_date date_data;

date_data: The internal DATE representation of the date.


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

Usage

The mi_binary_to_date() function converts the internal DATE value that date_data contains into a date string. It returns a pointer to the buffer that contains the resulting date string.

The mi_binary_to_date() function formats the date string in the date format of the current processing locale. It also performs any code-set conversion necessary between the current processing locale and the target locale.

Important: The mi_binary_to_date() function is supported only for compatibility with earlier versions of existing DataBlade® API modules. The DataBlade API will eventually discontinue support for this function. Use the mi_date_to_string() function in any new DataBlade API modules.

Return values

An mi_lvarchar pointer: A pointer to the date string that mi_binary_to_date() has created.
NULL: The function was not successful.
