Need a batch script to delete all records in a SQL Server CE database table. Don't know if its possible, I'm weak in scripting.
You can use my SqlCeCmd/SqlCeCmd40 command line utility from a batch file, with a command line like:
sqlcecmd -d "Data Source=C:\mydb.sdf" -q "DELETE * FROM MyTable"
(Or DROP the table and recreate with CREATE TABLE - faster)
