Description

This must be called after calling DatabasePrepare, once you have finished with the current SQL statement. You will not be able to call DatabasePrepare again, until the first one is finalized.

Note: Available in version 4.40 onwards.
Lua example 
-- insert a record
DatabasePrepare ("db", "INSERT INTO weapons (name, damage) VALUES ('sword', 42)")  --> returns 0 (sqlite3.OK)
DatabaseStep ("db")   -- returns 101 (sqlite3.DONE)
DatabaseFinalize ("db")  -- returns 0 (sqlite3.OK)
Lua notes 
The return codes are available in the sqlite3 table in Lua, as follows:

sqlite3.OK = 0
sqlite3.INTEGER = 1
sqlite3.INTERNAL = 2
sqlite3.PERM = 3
sqlite3.ABORT = 4
sqlite3.BUSY = 5
sqlite3.LOCKED = 6
sqlite3.NOMEM = 7
sqlite3.READONLY = 8
sqlite3.INTERRUPT = 9
sqlite3.IOERR = 10
sqlite3.CORRUPT = 11
sqlite3.NOTFOUND = 12
sqlite3.FULL = 13
sqlite3.CANTOPEN = 14
sqlite3.PROTOCOL = 15
sqlite3.EMPTY = 16
sqlite3.SCHEMA = 17
sqlite3.TOOBIG = 18
sqlite3.CONSTRAINT = 19
sqlite3.MISMATCH = 20
sqlite3.MISUSE = 21
sqlite3.NOLFS = 22
sqlite3.FORMAT = 24
sqlite3.RANGE = 25
sqlite3.NOTADB = 26
sqlite3.ROW = 100
sqlite3.DONE = 101
Returns 0: Completed OK

-1 : Database id not found
-2 : Database not open
-4 : Do not have prepared statement


Otherwise an SQLite return code. For example:

1: SQL error or missing database
5 : The database file is locked
21 : Library used incorrectly
Introduced in version 4.40
