The <span class="function"><strong>cubrid_lob2_import()</strong></span> function is used to save the
|
|
contents of BLOB/CLOB data from a file. To use this function, you must use
|
|
<span class="function"><a href="cubrid_lob2_new.html" class="function">cubrid_lob2_new()</a></span> or fetch a lob object from CUBRID database
|
|
first. If the file already exists, the operation will fail.
|
|
This function will not influence the cursor position of the lob object.
|
|
It operates the entire lob object.
