[GitHub] [shardingsphere] wuwu20048 opened a new issue, #17483: why 5.1.1 version The SQL clause 'IS' is unsupported?
wuwu20048 opened a new issue, #17483:
URL: https://github.com/apache/shardingsphere/issues/17483
## Bug Report
"is not null" or "<> null" was supported for encrypt cipher filed in 5.0.0 version . but in 5.1.1 version The SQL clause 'IS' is unsupported.
why ?
### Which version of ShardingSphere did you use?
5.1.1 version
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-JDBC
### Expected behavior
I want the “IS” work well for the cipher filed
### Actual behavior
```java
Caused by: org.apache.shardingsphere.infra.exception.ShardingSphereException: The SQL clause 'IS' is unsupported in encrypt rule.

### Reason analyze (If you can)
```java
static {
LOGICAL_OPERATOR.add("AND");
LOGICAL_OPERATOR.add("&&");
LOGICAL_OPERATOR.add("OR");
LOGICAL_OPERATOR.add("||");
SUPPORTED_COMPARE_OPERATOR.add("=");
SUPPORTED_COMPARE_OPERATOR.add("<>");
SUPPORTED_COMPARE_OPERATOR.add("!=");
SUPPORTED_COMPARE_OPERATOR.add(">");
SUPPORTED_COMPARE_OPERATOR.add("<");
SUPPORTED_COMPARE_OPERATOR.add(">=");
SUPPORTED_COMPARE_OPERATOR.add("<=");
}
private Optional<EncryptCondition> createBinaryEncryptCondition(final BinaryOperationExpression expression, final String tableName) {
String operator = expression.getOperator();
if (!LOGICAL_OPERATOR.contains(operator)) {
if (SUPPORTED_COMPARE_OPERATOR.contains(operator)) {
return createCompareEncryptCondition(tableName, expression, expression.getRight());
}
throw new ShardingSphereException("The SQL clause '%s' is unsupported in encrypt rule.", operator);
}
return Optional.empty();
}
```
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
### Example codes for reproduce this issue (such as a github link).
