James Taylor commented on PHOENIX-1580:
---------------------------------------
You can add this check in ParseNodeRewriter:
{code}
public static SelectStatement rewrite(SelectStatement statement,
ParseNodeRewriter rewriter) throws SQLException {
Map<String,ParseNode> aliasMap = rewriter.getAliasMap();
TableNode from = statement.getFrom();
TableNode normFrom = from == null ? null : from.accept(new
TableNodeRewriter(rewriter));
{code}
The ParseNodeRewriter is used to apply changes to a statement. Since the
statement itself is immutable, a traversal is made to copy the parts of the
statement that has changed.
