B4J Question SQLException SQL error or missing Database! Help Please

[sizap]

Helloy B4J folks,
i am trying to send Datas to my webserver and put them there into a SQL database named : SensorDatas.
Everything works but when my Handler trys to put the datas into the SQL database i receive this Exception.

java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database (near "17": syntax error)

I think that i understand what it means, but i don´t know how i can solve this issue.

Thats my Handler Code:

Sub Handle(req As ServletRequest, resp As ServletResponse)
    Dim data As sensorDatas = Main.ReadObject(req.InputStream)
    Dim m As Map
    m.Initialize
    m.Put("Datas",data.datas)
    m.Put("Date", data.date )
    DBUtils.InsertValues(Main.SQL1, "SDatas", m)
    Log("Datas added succesfully.")
End Sub

And here the Subroutine InsertValues:

Public Sub InsertValues (SQL As SQL, TableName As String, Values As Map)
    Dim sb As StringBuilder
    sb.Initialize
    sb.Append("INSERT INTO " & TableName & "(" & Values.GetKeyAt(0) & ", " & Values.GetKeyAt(1) & _
    ") VALUES (" & Values.GetValueAt(0) & ", " & Values.GetValueAt(1) & ")")
    Log(sb.ToString)
    SQL.ExecNonQuery(sb.ToString)
End Sub

The issue happend at the execute of the query.
I have no experience with SQL and Server, cause of that please be patient with me
And many thanks for youre help.

Are you trying to put string values into the database?
If you are, you will need to put a single quote before and after the value.
ie, values(one,two,three) need to be changed to values('one','two','three')

Please don't build such queries. You should use parameterized queries. See DBUtils.InsertMaps.
