JdbcTemplate.queryForMap should return first value of equally named columns [SPR-16578] #21120
Description
Philippe Marschall opened SPR-16578 and commented
When a ResultSet contains multiple columns which are equal when ignoring the case the Map returned by JdbcTemplate#queryForMap contains the value of the last column with the equal name. As an example think of the following query:
SELECT 1 as "X", 2 as "x"
from dual
However the specification of ResultSet states that
Column names used as input to getter methods are case insensitive. When a getter method is called with a column name and several columns have the same name, the value of the first matching column will be returned.
Affects: 5.0.4
