Knut Anders Hatlen commented on DERBY-5525:
-------------------------------------------
> So, we should this issue as invalid. Do we generate a truncation warning,
> though?
Right now we're not even truncating the value, so no truncation warning is
generated.
> Precision for UPPER function is wrong if the returned value is longer than
> the literal argument

> Key: DERBY-5525
> URL: https://issues.apache.org/jira/browse/DERBY-5525
> Project: Derby
> Issue Type: Bug
> Components: SQL
> Affects Versions: 10.8.2.2
> Reporter: Knut Anders Hatlen
>
> Seen in ij in a database with territory based collation and German locale:
> ==vv= COPIED FROM IJ CONSOLE =vv==
> ij> VALUES UCASE('Straßenbahn');
> 1
> -----------
> STRASSENBA&
> 1 Zeile ausgewählt
> ==================================
> And with JDBC calls:
> Connection c = DriverManager.getConnection(
> "jdbc:derby:memory:db;create=true;territory=de_DE;" +
> "collation=TERRITORY_BASED");
> Statement s = c.createStatement();
> ResultSet rs = s.executeQuery("values upper('Straße')");
> System.out.println(rs.getMetaData().getPrecision(1));
> rs.next();
> System.out.println(rs.getString(1));
> This prints
> 6
> STRASSE
> The precision is wrong, since the returned value is 7 characters long.
