Question

I’m using Luasqlite.

If I wanted to write a test to verify that a table exists, that returns boolean, how would I go about doing it?

It seems if I try selecting something from a table that doesn’t exist, as my test, then the application errors out altogether.

Thank you!

You could also query the table sqlite_master to look for your table, eg:

found=false
db:exec([[select * from sqlite_master where name='my_table';]],
function(...) print(...) found=true return 0 end)
if found then print'table exists!' end
