If you are using Save() on an update statement, PHP will throw a warning similar to "OCILobWrite: OCI_INVALID_HANDLE..." if your update statement did not catch any rows with its where clause.
OCI-Lob->save
说明
class OCI-Lob {bool save ( string data [, int offset] )
}
将 data 保存到大对象中。offset 参数可以用来指定从大对象开头起的偏移量。
如果成功则返回 TRUE，失败则返回 FALSE。
