Reproduce:

local table1 = { ... }
local table2 = { ... }
local db = sql.open(path)
db:insert{ table1, table2 }
assert.are.same("table", type(db:eval("select * from table1")))

After doing the insertation indvidiually, It errored out that one of the table
had undefined field in the sqlite table schema. However, after fixing that and
trying to re-run insert{}, same issue.

Expected

• It errors out as it would with indvidiual insertation.
• It insert multiple row in multiple tables successfully.

Suggestions

• Check if all table fields are vaild fields based on the table schema.
