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_date_to_string() functionThe mi_date_to_string() function creates a text (string) representation of a date value from the binary (internal) DATE representation.

The mi_date_to_string() function

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

Syntax

mi_string *mi_date_to_string(date_data)
   mi_date date_data;

date_data: The internal DATE format to convert to a date string.


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

Usage

The mi_date_to_string() function converts the internal DATE value that date_data contains into a date string. An internal DATE value is the format that the database server uses to store a value in a DATE column of the database.

Important: The mi_date_to_string() function replaces the mi_binary_to_date() function for converting an internal DATE value to a date string in DataBlade® API modules.

For GLS, the mi_date_to_string() function formats the date string in the date format of the current processing locale. For more information, see the HCL OneDB™ GLS User's Guide.

For more information about how to convert internal DATE format to date strings, see the HCL OneDB DataBlade API Programmer's Guide.

Return values

An mi_string pointer: A pointer to the date string equivalent of date_data.
NULL: The function was not successful.
