if i use the following statement, i receive the Nummer propper.
SQL=“SELECT Nummer FROM Sponning WHERE Type=‘17x57 Bi’;”
But i like to use for ‘17x57 Bi’ a string varable.
How to do that ??
SQL=“SELECT Nummer FROM Sponning WHERE Type=” + myvariablehere + “;”
You might want to add the single quotes as well…
SQL=“SELECT Nummer FROM Sponning WHERE Type=’” + myvariablehere + “’;”
Or better, use PreparedStatements. There might be single or double quotes in the string passed, you never know

it also works without the “;” at the end
