Long Data Type Support

In the esqlc, the long data select operation is done using the c-treeESQL programmatic interface tpe_sqlgetdata() and the insert operation is done using the interface tpe_sqlputdata(). These C interfaces require the field handle as their argument. Two new field handle types have been introduced for this purpose. They are:

• lvc_fld_hdl_t : Field handle type for LVARCHAR column.
• lvb_fld_hdl_t : Field handle type for LVARBINARY column.

The above field handles type host variable need to be used in the EXEC SQL statement to get the field handle of the long column.
