SQL Truncate, Delete, Drop advise

Question

I have a table in a SQL db that I want to remove the data from? I want to keep the columns though.

e.g. my table has 3 columns, Name, Age, Date. I don\'t want to rem

Truncate is very fast - like quick format of the table. It does not require any extra space when deleting. You can not rollback his operation. You can not specify conditions. This is best choice for deleting all data from table.

Delete is much slower and you need extra space for this operation, because you must be able to rollback the data. If you need to delete all data, use truncate. If you need to specify conditions, use delete.

Drop table - you can delete data from table by dropping and creating it again like you would truncate it, but it is slower and you can have some other problems, like foreign key dependencies. I definitely don't recommend this operation.
