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 invdivdbl() functionThe invdivdbl() function divides an interval value by a numeric value.

The invdivdbl() function

The invdivdbl() function divides an interval value by a numeric value.

Syntax

mint invdivdbl(iv, num, ov)
   intrvl_t *iv;
   double num;
   intrvl_t *ov;

iv: A pointer to the interval value to be divided.
num: A numeric divisor value.
ov: A pointer to an interval variable with a valid qualifier, to contain the result of the division.

Usage

The input and output qualifiers must both belong to the same interval class: either the year to month class or the day to fraction(5) class. If the qualifier for ov is different from the qualifier for iv (within the same class), the invdivdbl() function extends the result (as the invextend() function defines).

The invdivdbl() function divides the interval value in iv by num and stores the result in ov.

The value in num can be either a positive or a negative value.

Return values

0: The division was successful.
<0: The division failed.
-1200: A numeric value is too large (in magnitude).
-1201: A numeric value is too small (in magnitude).
-1202: The num parameter is zero.
-1265: Overflow occurred on an interval operation.
-1266: An interval value is incompatible with the operation.
-1268: A parameter contains an invalid interval qualifier.
