Combining two tables in sqlite3 - sql

Question

I have two tables in two separate sqlite3 databases. The datatypes are identical, but the schemas slightly different. I want them to be a single table in a single database with the same schema as Table 2
Table 1
CREATE TABLE temp_entries (
id INTEGER PRIMARY KEY,
sensor NUMERIC,
temp NUMERIC,
date NUMERIC);
Table 2
CREATE TABLE "restInterface_temp_entry" (
"id" integer NOT NULL PRIMARY KEY,
"dateTime" integer NOT NULL,
"sensor" integer NOT NULL,
"temp" integer NOT NULL
);
id is not unique between the two tables. I would like to create another table with the same schema as Table 2. I would like the id for the entries in Table 1 to start from 0 and then the entries from table 2 to start after the last entry from table 1.
Ideally I would like to just add the entries from Table 1 to Table 2 and "reindex" the primary key so that it was in the same ascending order that "dateTime" is.
UPDATE: I now have both tables using the same schema, I did this by creating a new table with the same schema as Table 2 into the database that held Table 1. I than copied the data to the new table with something like:
INSERT INTO restInterface_temp_entry(id,dateTime,sensor,temp)
...> select id,date,sensor,temp FROM temp_entries;
Background
I used to record a bunch of temp_entries to a csv file. I wanted to put the data into a format that was easier to work with and chose sqlite3. I wrote a program that pulled all of the entries out and put them into Table 1. I wasn't sure what I was doing at the time, and used Table 2 for all new entries. Now I want to combine them all, hopefully keeping id and date in ascending order.

Answer 1

Figured it out.
Open current database.
Attach to original database
ATTACH '/orig/db/location' as orig
Move records from current database to old database, leaving out the PK
insert into orig.restInterface_temp_entry(dateTime,sensor,temp)
...> select dateTime,sensor,temp from main.restInterface_temp_entry;
Clear current databases table
delete from main.restInterface_temp_entry where id > 0
Copy everything updated records from original databases table back to current.
insert into main.restInterface_temp_entry(id,dateTime,sensor,temp)
...> select id,dateTime,sensor,temp
...> from orig.restInterface_temp_entry;

Answer 2

I'm assuming SQLLite supports INSERT INTO SELECT
INSERT INTO newtable (id, datetime, sensor, temp)
SELECT id, date, sensor, temp
FROM temp_entries
ORDER BY id;
INSERT INTO newtable (id, datetime, sensor, temp)
SELECT "id", "dateTime", "sensor", "temp"
FROM "restInterface_temp_entry"
ORDER BY "id";
This should do the trick.
