cubrid_lob2_export

Export the lob object to a file

&reftitle.description; `bool` `cubrid_lob2_export` `resource` `lob_identifier` `string` `file_name`

The `cubrid_lob2_export` function is used to save the contents of BLOB/CLOB data to a file. To use this function, you must use `cubrid_lob2_new` 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.

&reftitle.parameters;

`lob_identifier`

- Lob identifier as a result of `cubrid_lob2_new` or get from the result set.

`filename`

- File name you want to store BLOB/CLOB data. It also supports the path of the file.
