- - ### Method Detail

    - #### detach

          FirebirdBlob detach()
                       throws java.sql.SQLException

      Detach this blob. This method creates new instance of the same blob database object that is not under result set control. When result set is closed, all associated resources are also released, including open blob streams. This method creates a new instance of blob object with the same blob ID that can be used even when result set is closed.

      Note, detached blob will not remember the stream position of this object. This means that you cannot start reading data from the blob, then detach it, and then continue reading. Reading from detached blob will begin at the blob start.

      Returns:
        instance of `FirebirdBlob` that is not under result set control.
      Throws:
        `java.sql.SQLException` - if Blob cannot be detached.

    - #### isSegmented

          boolean isSegmented()
                       throws java.sql.SQLException

      Check if blob is segmented. If Blob is segmented, you cannot use `FirebirdBlob.BlobInputStream.seek(int)` method.
      Returns:
        `true` if this blob is segmented, otherwise `false`
      Throws:
        `java.sql.SQLException`
