I have a query that takes one column row from database and I want to set this data to my model. My model name is Pictures and my method is follow:
@Override
public Pictures getPictureList() throws Exception {
JdbcTemplate jdbc = new JdbcTemplate(datasource);
String sql= "select path from bakery.pictures where id=1";
Pictures pcList = jdbc.query(sql, new BeanPropertyRowMapper<Pictures>(Pictures.class));
return pcList;
}
This method returns "a query was Inferred to list".
How can I solve it?
java spring-boot

Use JdbcTemplate.queryForObject() method to retrieve a single row by it's primary key.
Pictures p = jdbc.queryForObject(sql,
new BeanPropertyRowMapper<Pictures>(Pictures.class));
JdbcTemplate.query() will return multiple rows which makes little sense if you are querying by primary key.
List<Pictures> list = jdbc.query(sql,
new BeanPropertyRowMapper<Pictures>(Pictures.class));
Picture p = list.get(0);
