The ifx_lo_truncate() function
The ifx_lo_truncate() function truncates a smart large object at the specified position.
Syntax
ifx_lo_truncate(lofd, offset)Arguments
The function
accepts the following arguments.
| Argument | Type | Use | Description |
|---|---|---|---|
| lofd | SQL_INTEGER | Input | Smart-large-object file descriptor |
| offset | SQL_BIGINT | Input | End of the smart large object. If this value exceeds
the end of the smart large object, the function extends the smart
large object. If this value is less than the end of the smart large
object, the database server reclaims all storage from the offset position
to the end of the smart large object. Instead of using the default HCL OneDB™ ODBC Driver C data type of SQL_C_CHAR for offset, use SQL_C_LONG or SQL_C_SHORT. |
Usage
The ifx_lo_truncate() function sets the end of a smart large object to the location that the offset argument specifies.
