The problem with it saying things like "I'm not going to go into this in detail, because it is almost exactly the same as adding a record." is that as soon as you encounter a problem because you're a beginner, you're completely lost

I'm trying to work out how to just clear the database entirely for the time being just so I can reset it for testing purposes after putting a few things in. Obviously "Mary" and "Smith" are placeholders, but what's the correct phrasing on the line:
DELETE FROM tTableName WHERE NameP = 'Mary' AND MessageP = 'Smith' into tSQL
put "MessagesP" into tTableName
put "NameP, MessageP" into tFields
put the text of field "nameField" into tName
put the text of field "textEntry" into tMessage
DELETE FROM tTableName WHERE NameP = 'Mary' AND MessageP = 'Smith' into tSQL
revExecuteSQL gConnectionID, tSQL, "tName", "tMessage"
