I'm using SQLite, and I have a table for properties, and a table for sub-properties. Each sub-property points to its parent using the fkPropertyId column. Right now, to create the initial database, I've got a script that looks something like this:
INSERT INTO property VALUES(1,.....);
INSERT INTO property VALUES(2,.....);
INSERT INTO property VALUES(3,.....);
INSERT INTO subproperty VALUES(1,.....,3);
INSERT INTO subproperty VALUES(2,.....,3);
INSERT INTO subproperty VALUES(3,.....,3);
INSERT INTO property VALUES(4,.....);
Now, I want to get rid of the hard-coded rowId, so it would be something like:
INSERT INTO property VALUES(NULL,.....);
INSERT INTO property VALUES(NULL,.....);
INSERT INTO property VALUES(NULL,.....);
INSERT INTO subproperty VALUES(NULL,.....,X);
INSERT INTO subproperty VALUES(NULL,.....,X);
INSERT INTO subproperty VALUES(NULL,.....,X);
INSERT INTO property VALUES(NULL,.....);
Where x refers to the last inserted rowId in the property table. Right now, that's
(SELECT MAX(rowId) FROM property)
Is there any better (and more technically accurate) way to write this script?
Use the last_insert_rowid
function:
SELECT last_insert_rowid();
