Question

I have a parser that parses XML file into SQLite database, and the current implementation generates the ‘create table xyz …’ even the table is already existed.

• Is this OK? I mean, is this OK to run ‘create table’ even when the table exists in db?
• If not, is there easy way to check the names of tables (and its contents) that SQLite db has?

Answer 1

What you are searching for is CREATE TABLE IF NOT EXISTS and the FAQ entry How do I list all tables/indices contained in an SQLite database.

Creating a table without the “IF NOT EXISTS” option will lead to an error.
