Create a CLOB

说明

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

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。

范例

$filename = "clob_file.txt";
$fp = fopen($filename, "rb");
$clobdata = fread($fp, filesize($filename));
fclose($fp);
$clobHandle = fbsql_create_clob($clobdata, $link);
$sql = "INSERT INTO CLOB_TABLE (CLOB_COLUMN) VALUES ($clobHandle);";
$rs = fbsql_query($sql, $link);
