Rajesh Kartha commented on DERBY-1837:
--------------------------------------
I am positive now this an ij issue, if I create a simple jdbc test I am able to
get the correct column names back.
ResultSet rs=stmt.executeQuery("select * from
(values('aaa','a')) as a(c1,c2)");
ResultSetMetaData rsmd=rs.getMetaData();
while(rs.next()){
System.out.println(rsmd.getColumnName(1)+"\t"+rsmd.getColumnName(2));
System.out.println(rs.getString(1)+"\t"+rs.getString(2));
}
System.out.println("====================================================");
rs=stmt.executeQuery("select * from (values('a','a')) as
a(c1,c2)");
rsmd=rs.getMetaData();
while(rs.next()){
System.out.println(rsmd.getColumnName(1)+"\t"+rsmd.getColumnName(2));
System.out.println(rs.getString(1)+"\t"+rs.getString(2));
}
returns:
C1 C2
aaa a
====================================================
C1 C2
a a

> A select from a derived table does not return the aliased column names
> correctly if the selected column(s) are char(1). The column names
> show up as '&' in the following example:
> ij> select * from (values('a','a')) as a(c1,c2);
> &|&
> ---
> a|a
> 1 row selected
> ij> select * from (values('a','aa')) as a(c1,c2);
> &|C2
> ----
> a|aa
> 1 row selected
> ij> select * from (values('aaa','a')) as a(c1,c2);
> C1 |&
> -----
> aaa|a
> 1 row selected
> ij> select * from (values(1,'a')) as a(c1,c2);
> C1 |&
> -------------
> 1 |a
> 1 row selected
