Delete records from table?

how to delete a subset of records within a table ? For example, if I have a particular set of records (table B) that I know they are a subset within a big table A. Both have exactly number of fields, etc. HOW do I delete the same records of table B from big table A.

I wish I can select the result directly from table A. In other words, I can NOT query out to get the result table B from table A, because the criteria is NOT simple. My result of table B had to get from joining different ways to get the result.

My question is HOW do I delete records from a bigger table A for the same EXACT # of records in another smaller table B?

Delete First Record in a Table?

I've got a situation where I need to append data to an empty table that will autonum the records for me, delete the first record of that table, run a series of queries using the table's data without that first record, then delete all the records from that table again to set it up for the next time that event needs to fire.

I'm having trouble figuring out how to delete just the first record from that table automatically as part of the sequence of events.

The DELETE Operand in SQL for MS ACCESS

DELETE is one of the simpler SQL commands, and can be used to delete rows (or records) permanently from a table. It's very useful if you're trying to purge old data from your records. If you want to archive your records, however, you're better off SELECTing records and saving them to a new table first (which you'll archive), and then DELETEing the same records.

Delete records from a table: Use Find Dups Query & Delete or not?

I have a new database that contains a table called Table_PartNumbers. It contains a list of all the part numbers with all of our customers. In my initial data entry I accidentally duplicated 4 part numbers.

Can I just delete the records from the table (select then delete) or should I get rid of them by creating a Find Duplicates Query, convert it to a Delete Query and take care of them that way?

At this point nothing bad will happen to my database if I just click and delete the 4 extra records. All the part numbers have a unique ID and the database is so fresh that there aren't any records in any other tables that reference the duplicates.

But, since I'm trying to learn 'proper' technique this go around, I was wondering what proper steps should be followed?

I found this link below but I just don't quite understand if this something you always want to do or it is okay to just delete records if there is no chance of database corruption?
