Restriction.toSQL() doesn't escape special characters
-----------------------------------------------------
Key: DERBY-4654
URL: https://issues.apache.org/jira/browse/DERBY-4654
Project: Derby
Issue Type: Bug
Components: SQL
Affects Versions: 10.6.1.0
Reporter: Knut Anders Hatlen
Priority: Minor
org.apache.derby.vti.Restriction.toSQL() adds double quotes around column
names, but it does not escape the special characters (like double quotes) in
the column names, so the returned string may not be valid SQL. This could cause
problems when using the restriction to generate a query against an external
database.
Restriction.doubleQuote() should use IdUtil.normalToDelimited() to get proper
quoting of the names.
