### Which version of ShardingSphere did you use?
shardingsphere-jdbc:5.0.0-alpha
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-JDBC
### Expected behavior
### Actual behavior
Caused by: java.lang.ClassCastException:
org.apache.shardingsphere.sql.parser.sql.common.segment.dml.item.ExpressionProjectionSegment
cannot be cast to
org.apache.shardingsphere.sql.parser.sql.common.segment.dml.expr.simple.LiteralExpressionSegment
### Reason analyze (If you can)
1. as follows sql, when i config 'name' use ENCRYPT, my sql like 'ON
DUPLICATE KEY UPDATE name=VALUES(name)' will throw As above exception, but i
change the sql like this 'ON DUPLICATE KEY UPDATE name=?', ENCRYPT is work good.
2. i trace the code, find ENCRYPT field will use OnDuplicateUpdateContext
public Object getValue(final int index) {
ExpressionSegment valueExpression = valueExpressions.get(index);
return valueExpression instanceof ParameterMarkerExpressionSegment ?
parameters.get(getParameterIndex(valueExpression)) :
((LiteralExpressionSegment) valueExpression).getLiterals();
}
3. when name=VALUES(name) valueExpression will is
ExpressionProjectionSegment, is not LiteralExpressionSegment so will throw as
above exception.
4. when name=? valueExpression will is ParameterMarkerExpressionSegment ,
is work good.
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule
configuration, when exception occur etc.
INSERT INTO anchor_info (id, source, anchorId, name, avatar, status,
createTime, updateTime) VALUES
(#{id,jdbcType=BIGINT}, #{source,jdbcType=VARCHAR},
#{anchorId,jdbcType=VARCHAR}, #{name,jdbcType=VARCHAR},
#{avatar,jdbcType=VARCHAR},#{status,jdbcType=TINYINT},
#{createTime,jdbcType=BIGINT}, #{updateTime,jdbcType=BIGINT})
ON DUPLICATE KEY UPDATE name=VALUES(name),
updateTime=VALUES(updateTime);
rules:
!ENCRYPT
tables:
anchor_info:
columns:
name:
cipherColumn: name
encryptorName: aes
encryptors:
aes:
type: AES
props:
