Update-Problem with flat-ASCII and mysql
|
Can't Post
|
|
Hi there,
I have a special type of flat-ascii file, where all data are written one after another. My perl-scills are very basic, but I tried my best to create a script.
with the "insert-part" everything work, but there is no check if the dataset is already in. I don't know how to manage this. If I load the script twice, I have dublettes in.
In the update-part I have 3 states of possiblities:
1) change of datafield
2) datafield is empty - new insert
3) datefield will be deleted to NULL
It seemes 1) and 2) work but 3) has an error in the SQL-String
UPDATE "adress" SET where Key_adr =5648
cause the value is missing after SET
Has anyone an idea?
I attach 2 scripts, one to create a db, and another for the update and a sample ascii-file.
I'm lucky about every hint
Thanx
Axel
