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_lo_specset_def_open_flags() functionThe mi_lo_specset_def_open_flags() function sets the default open-mode flag for a smart large object.

The mi_lo_specset_def_open_flags() function

The mi_lo_specset_def_open_flags() function sets the default open-mode flag for a smart large object.

Syntax

mi_integer mi_lo_specset_def_open(LO_spec, def_open_flags)
   MI_LO_SPEC *LO_spec;
   mi_integer def_open_flags;

LO_spec: A pointer to the LO-specification structure in which to save the default open flags.
def_open_flags: An integer value that specifies the bit mask of the default open flags for the smart large object.


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

Usage

The mi_lo_specset_def_open_flags() function is the LO-specification accessor function that sets the default open flags for a new smart large object. The def_open_flags value is the bit mask that indicates which open flags to use when the mi_lo_open() opens the smart large object. The default open flags indicate how the mi_lo_open() function opens the smart large object when it does not include an open flag. To override the default open flags, you can specify an open mode as an argument to mi_lo_open().

For more information about the default open mode of a smart large object or about how to use the mi_lo_specset_def_open_flags() function, see the HCL OneDB™ DataBlade® API Programmer's Guide.

Return values

MI_OK: The function was successful.
MI_ERROR: The function was not successful.
