java.sql.SQLFeatureNotSupportedException: can't get index from
columnLabel[xxxxxxxxx].
### Which version of ShardingSphere did you use?
<dependency>
<groupId>org.apache.shardingsphere</groupId>
<artifactId>shardingsphere-jdbc-core-spring-boot-starter</artifactId>
<version>5.2.0</version>
</dependency>
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
shardingsphere-jdbc Read/Write Splitting
### Expected behavior
java:
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;
}
in this projections ,there has some ExpressionProjection, but not add to
result.
sql:
select ifnull(sell_price,0) productPrice from product where id=1;
ifnull(sell_price) productPrice is a ExpressionProjection
