Description

The update section of "merge SQL" reports an error when using an alias

// if i replace red code with "b = '123456'", I don't get an error
String sql = "merge into xxx as t1 using yyy as t2 on t1.a = t2.a when matched then update set t1.b = '123456'" ; 
SqlParser.ConfigBuilder configBuilder = SqlParser.configBuilder();
configBuilder.setCaseSensitive(false);

SqlParser parser = SqlParser.create(sql, config);
SqlNode node = parser.parseQuery();
