/* Program name: text_image.cp
**
** Description: Inserting text and image data
using host
** variables of types CS_TEXT and CS_IMAGE.
** Notes: This is a new feature in 11.x which
allows you to use
** host variables of type CS_TEXT and
CS_IMAGE in insert
** or update statements to handle text or image
data. You don't
** need to use to mixed-mode client-library programming or
** dynamic sql, which had a limit of 64 k bytes.
** The size of the text or image data that can
now be sent is
** limited only by memory or the maximum size
allowed for
** text and image data by the SQL Server. However,
** the larger the data being sent this way, the
slower the
** performance.
**
** Script file: text_image.sql
**
** Notes: Make sure you compile the program using
the '-y'
** precompiler flag.
