Can these three SQLITE INSERTS be combinded or improved?

I have three tables:

CREATE TABLE "local" ("id" INTEGER PRIMARY KEY  AUTOINCREMENT  NOT NULL , "serialNumber" TEXT, "location" TEXT)

CREATE TABLE "setups" ("id" INTEGER PRIMARY KEY  NOT NULL ,"hold" TEXT,"mode" INTEGER,"setTemp" REAL,"maxSTemp" REAL,"minSTemp" REAL,"units" TEXT,"heat" INTEGER,"heatMode" INTEGER,"fanMode" INTEGER,"fan" INTEGER,"cool" IN开发者_如何学CTEGER)

CREATE TABLE "data" ("id" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL ,"humidity" REAL,"time" INTEGER,"filtChng" INTEGER,"indoorTemp" REAL,"outdoorTemp" REAL, "setups_id" INTEGER, "local_id" INTEGER)

Everytime I get a new entry I execute:

INSERT INTO local ('serialNumber') SELECT 'XXXX' WHERE NOT EXISTS (SELECT * FROM local WHERE serialNumber='XXXX')"

INSERT INTO setups ('hold','mode','setTemp','maxSTemp','minSTemp','units','heat','heatMode','fanMode','fan','cool') SELECT '00',1,74.0,74.0,74.0,'F',1,1,1,1,1 WHERE NOT EXISTS (SELECT * FROM setups WHERE hold='00' AND mode=1 AND setTemp=74.0 AND maxSTemp=74.0 AND minSTemp=74.0 AND units='F' AND heat=1 AND heatMode=1 AND fanMode=1 AND fan=1 AND cool=1)

 INSERT INTO data ('humidity','filtChng','time','indoorTemp','outdoorTemp',local_id,setups_id) SELECT 74.0,111111111,100,74.0,74.0,local.id,setups.id FROM local CROSS JOIN setups WHERE local.serialNumber='XXXX' AND setups.hold='00' AND setups.mode=1 AND setups.setTemp=74.0 AND setups.maxSTemp=74.0 AND setups.minSTemp=74.0 AND setups.units='F' AND setups.heat=1 AND setups.heatMode=1 AND setups.fanMode=1 AND setups.fan=1 AND setups.cool=1

What I am doing works, but seems slow and redundant/inefficient...

Well, you can remove the "where not exists" part from the "local" insert if you use a unique constraint on the "serialNumber" field. Be careful, this will throw a constraint violation instead of just not inserting the row. So be sure to handle that in the application.

And though I assume it is, be sure that checking for duplicates is really necessary in your app.
