```java
org.apache.shardingsphere.infra.binder.segment.select.projection.engine.ProjectionEngine
private Collection<ColumnProjection> getColumnProjections(final
Collection<Projection> projections) {
Collection<ColumnProjection> result = new LinkedList<>();
for (Projection each : projections) {
if (each instanceof ColumnProjection) {
result.add((ColumnProjection) each);
}
if (each instanceof ShorthandProjection) {
result.addAll(((ShorthandProjection)
each).getActualColumns().values());
}
}
return result;
}
```
`id + 1` is a `ExpressionProjection`, so this function will skip
`ExpressionProjection`, may be this occur the problem.
