Thanks. Unfortunately I don't have a choice. An application I don't have
control over expects such strange table names.

Re: [sqlite] Newbie problem using special column name
Hi,
try enclosing your column name with double quotes "
create table test("column-1" varchar(255))
However, i strongly advise not to use this character, because it is the
minus-operator in sql. You will have to make sure that you enclose the
column name every time you (or somone other) uses ist.

Welcome to the SQLite list.

Make this
create table test([column-1] varchar(255));
or
create table test("column-1" varchar(255));
Both work

[sqlite] Newbie problem using special column name
Can I add a column name containing a dash "-" and if yes, how would I do that? I am asking because I fail to add a column name that contains a dash "-" and I don't know if I cause the problem (easy solution) or if its something else causing this to fail. Here's what I try: sqlite> create table test(column-1 varchar(255)); SQL error: near "-": syntax error So far I have had a look at the SQLite documentation, but couldn't find anything that would tell me about 'reserved' characters or how I would escape a dash.
