fbsql_create_clob — Create a CLOB

说明

string fbsql_create_clob ( string $clob_data [, resource $link_identifier ] )

Creates a CLOB from the given data.

参数

clob_data

The CLOB data.

link_identifier

由 fbsql_connect() 或 fbsql_pconnect() 返回的 FrontBase 链接标识符.

如可选并未指定，函数会尝试查找一个到 FrontBase 服务器的开放链接，且如没有找到这样的链接，会尝试通过不带参数调用 fbsql_connect() 来创建一个。

 $fp  =  fopen ( $filename ,  "rb" );
 $clobdata  =  fread ( $fp ,  filesize ( $filename ));
 fclose ( $fp );

 $clobHandle  =  fbsql_create_clob ( $clobdata ,  $link );
