px_set_blob_file

说明

Sets the name of the file where blobs are going to be read from. Without calling this function, px_get_record() will only return data in blob fields if the data is part of the record and not stored in the blob file. Blob data is stored in the record if it is small enough to fit in the size of the blob field.

Calling this function twice will close the first blob file and open the new one.

返回值

如果成功则返回 TRUE，失败则返回 FALSE。
