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 invdivinv() function

The invdivinv() function divides an interval value by another interval value.

Syntax

mint invdivinv(i1, i2, num)
   intrvl_t *i1, *i2;
   double *num;

i1: A pointer to the interval value that is the dividend.
i2®: A pointer to the interval value that is the divisor.
num: A pointer to a double variable to contain the quotient.

Usage

The invdivinv() function divides the interval value in i1 by i2 and stores the result in num. The result can be either positive or negative.

Both the input and output qualifiers must belong to the same interval class: either the year to month class or the day to fraction(5) class. If necessary, the invdivinv() function extends the interval value in i2 to match the qualifier for i1 before the division.

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).
-1266: An interval value is incompatible with the operation.
-1268: A parameter contains an invalid interval qualifier.
