Question

I use Firefox plugin SQLite Manager execute my SQL:

    declare @id int
    declare @lon float
    declare @lat float
    set @id=5
    set @lon=118.476000
    set @lat=32.033720
    while @i<=10000
      begin
        INSERT INTO njdm 
          (ID,dalei,xiaolei,hanyi,level,longitude,latitude) 
        VALUES 
          (@id, 5, 10, "地名描述",1,@lon,@lat)

        set @id=@id+1
        set @lon=@lon+0.000010
        set @lat=@lat+0.000010
      end

And get the error:

    [ near "declare": syntax error ]
    Exception Name: NS_ERROR_FAILURE
    Exception Message: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE)                          [mozIStorageConnection.createStatement]

any help?TIA!

SQLite supports only SQL operations, it does not directly support variables, variable assignments, looping, or other program constructs. You will need to write this code in some other language that supports those constructs, then send the commands to SQLite either by constructing dynamic SQL or by using one of the SQLite support libraries associated with your selected language.
