View list of data type meanings

Description

This returns a string which is the most recent automatically allocated database key (for example, if you are using autoincrement on the primary key). Internally it is a 64-bit number, but since there is no ready mechanism for returning 64-bit numbers via the scripting interface, MUSHclient converts it to a string, and returns that.


Available in MUSHclient version 4.40 onwards.



Lua example

last_key = DatabaseLastInsertRowid ("db")


Return value

A string which is the most recently-allocated key. May be zero if there is no such key.
