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 dectolong() functionThe dectolong() function converts a decimal type number into an int4 type number.

The dectolong() function

The dectolong() function converts a decimal type number into an int4 type number.

Syntax

mint dectolong(dec_val, lng_val)
   dec_t *dec_val;
   int4  *lng_val;

dec_val: A pointer to the decimal structure that contains the value to convert to an itn4 integer.
lng_val: A pointer to an int4 variable to contain the result of the conversion.

0: The conversion was successful.
-1200: The magnitude of the decimal type number is greater than 2,147,483,647.
