Client APIs and toolsYou can use the HCL OneDB™ implementation of client APIs to develop applications for HCL OneDB™ database servers.
HCL OneDB™ ODBC Driver GuideThe HCL OneDB™ ODBC Driver Programmer's Manual serves as a user guide and reference for HCL OneDB™ ODBC Driver, which is the HCL OneDB™ implementation of the Microsoft™ Open Database Connectivity (ODBC) interface, Version 3.0.
Client functionsThese topics describe the HCL OneDB™ ODBC Driver client functions. Use these functions to access and manipulate smart large objects and rows and collections.
Functions for smart large objectsThis section describes each client function that the driver provides for smart large objects.

The ifx_lo_specget_estbytes() function

The ifx_lo_specget_estbytes() function gets the estimated number of bytes from a smart-large-object specification structure.

Syntax

ifx_lo_specget_estbytes(lospec, estbytes)

Arguments

The function accepts the following arguments.


Argument	Type	Use	Description
lospec	SQL_INFX_UDT_FIXED	Input	Smart-large-object specification structure
estbytes	SQL_BIGINT	Output	Estimated final size of the smart large object, in bytes. This estimate is an optimization hint for the smart-large-object optimizer. Instead of using the default HCL OneDB™ ODBC Driver C data type of SQL_C_CHAR for estbytes, use SQL_C_LONG.

Usage

The ifx_lo_specget_estbytes() function gets the estimated number of bytes from a smart-large-object specification structure.
