SQLite3 using a variable when creating a table?

I am hoping to pass a table name as a variable when I am creating a table with Ruby and in SQLite3.

Here is what I have so far:

$db.execute %q{
  CREATE TABLE @tableName (
  id integer primary key,
  term varchar(100),
  meaning varchar(100))
}

$db is defined as

$db = SQLite3::Database.new("test.db")
$db开发者_Python百科.results_as_hash = true

@tableName is user input. I can see that it doesn't like the @tableName, but I don't know how to work around that.

%q is a single quote alternative, interpolation does not work inside single quoted strings. Also in ruby interpolation is done with #{}, like in "Welcome #{name}". I would try:

$db.execute <<-SQL
  CREATE TABLE #{@tableName} (
    id integer primary key,
    term varchar(100),
    meaning varchar(100)
  )
SQL

Just use normal string interpolation:

$db.execute %Q{
  CREATE TABLE #{@tableName} (
  id integer primary key,
  term varchar(100),
  meaning varchar(100))
}

Note that I switched your %q{} quoting to %Q{} to get the interpolation to work.
