URL: https://github.com/apache/shardingsphere/issues/8303
### Which version of ShardingSphere did you use?
5.0.0
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
shardingProxy
The problem occued in my project when i invoke interface for updating .
and the sharding key is not null. the result is ok when i change the proxy
version to 4.1.1
part of proxy config:
pbcst_qry_info:
actualDataNodes: ms_ds.pbcst_qry_info_${0..15}
tableStrategy:
standard:
shardingColumn: ecif_cust_no
shardingAlgorithmName: pbcst_qry_info_inline
databaseStrategy:
standard:
shardingColumn: ecif_cust_no
shardingAlgorithmName: database_inline
keyGenerateStrategy:
column: ecif_cust_no
keyGeneratorName: snowflake
pbcst_qry_info_inline:
type: INLINE
props:
algorithm-expression:
pbcst_qry_info_${Math.abs(ecif_cust_no.hashCode() % 16)}
log:
