Inner exception: {}

Second: After the Save as format is deleted, the system format is followed by a "111111" format, and this format is not removed

Two problems solved by one operation

SELECT * FROM Lszbgs

WHERE f_gsmc= ' 111111 ' (Deleted system format)

The record is then deleted after the backup

Two problems are solved!
