Here's a quick GHCi session with HDBC.

Prelude> :m +Database.HDBC
Prelude Database.HDBC> :m +Database.HDBC.Sqlite3
Prelude Database.HDBC Database.HDBC.Sqlite3> conn <- connectSqlite3 "mydb"
Prelude Database.HDBC Database.HDBC.Sqlite3> quickQuery conn "CREATE TABLE
mytable (FirstName varchar, LastName varchar, Age int )" []
[]
Prelude Database.HDBC Database.HDBC.Sqlite3> quickQuery conn "INSERT INTO
mytable VALUES ('Sebastian','Sylvan',26)" []
[]
Prelude Database.HDBC Database.HDBC.Sqlite3> commit conn
Prelude Database.HDBC Database.HDBC.Sqlite3> quickQuery conn "SELECT * FROM
mytable" []
[[SqlString "Sebastian",SqlString "Sylvan",SqlString "26"]]
Prelude Database.HDBC Database.HDBC.Sqlite3> disconnect conn


Not sure why that Age field came back as a string though :-)
