px_set_blob_file

(PECL paradox >= 1.3.0)

px_set_blob_fileSets the file where blobs are read from

说明

bool px_set_blob_file ( resource $pxdoc , string $filename )

Sets the name of the file where blobs are going to be read from or written into. Without calling this function, px_get_record() or px_retrieve_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 px_put_record(), px_insert_record(), or px_update_record() without calling px_set_blob_file() will result in truncated blob fields unless the data fits into the database file.

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

参数

pxdoc

Resource identifier of the paradox database as returned by px_new().

filename

The name of the file. Its extension should be .MB.

返回值

如果成功则返回 TRUE,失败则返回 FALSE
