cubrid_lob2_import

(PECL CUBRID >= 8.4.1)

cubrid_lob2_import — Import BLOB/CLOB data from a file.

说明

bool cubrid_lob2_import ( resource $lob_identifier , string $file_name )

The cubrid_lob2_import() function is used to save the contents of BLOB/CLOB data from 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.

参数

lob_identifier: Lob identifier as a result of cubrid_lob2_new() or get from the result set.
filename: File name you want to import BLOB/CLOB data. It also supports the path of the file.

返回值

TRUE if the process is successful and FALSE for failure.

 cubrid_execute ( $conn , "CREATE TABLE test_lob (id INT, contents CLOB)" );
 
 $req  =  cubrid_prepare ( $conn ,  "INSERT INTO test_lob VALUES (?, ?)" );
 cubrid_bind ( $req ,  1 ,  1 );

 $lob  =  cubrid_lob2_new ( $conn ,  "clob" );
 cubrid_lob2_import ( $lob ,  "doc_1.txt" );
