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_string_to_decimal() functionThe mi_string_to_decimal() function converts a text (string) representation of a decimal value to its binary (internal) DECIMAL representation.

The mi_string_to_decimal() function

The mi_string_to_decimal() function converts a text (string) representation of a decimal value to its binary (internal) DECIMAL representation.

Syntax

mi_decimal *mi_string_to_decimal(decimal_string)
   mi_string *decimal_string;

decimal_string: A pointer to the decimal string to convert to its internal DECIMAL format.


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

Usage

The mi_string_to_decimal() function converts the decimal string that decimal_string references to its internal DECIMAL (mi_decimal) value. An internal DECIMAL value is the format that the database server uses to store a value in a DECIMAL column of the database. This format can represent both fixed-point and floating-point decimal numbers.

Important: The mi_string_to_decimal() function replaces the mi_decimal_to_binary() function for string-to-internal-DECIMAL conversion in DataBlade® API modules.

The mi_string_to_decimal() function accepts the decimal string in the numeric format of the current processing locale. For more information, see the HCL OneDB™ GLS User's Guide.

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

Return values

An mi_decimal pointer: A pointer to the internal DECIMAL representation that mi_string_to_decimal() has created.
NULL: The function was not successful.
