duerwuyi opened a new issue, #37422: URL: https://github.com/apache/shardingsphere/issues/37422
## Bug Report ### Which version of ShardingSphere did you use? shardingsphere-proxy 5.5.2 postgres 17.2 as backend ### Expected behavior insertion succeed in all three types of timestamp. ### Actual behavior `TIMESTAMP '...'` is a typed literal of PG, should be routed as a normal literal, instead of an error. Furthermore, we suggest supporting routing `make_timestamp()` when its arguments are all literals. ```sql testdb=> CREATE SHARDING TABLE RULE t100 ( STORAGE_UNITS(ds_0,ds_1,ds_2,ds_3,ds_4), SHARDING_COLUMN=colocated_key, TYPE(NAME="AUTO_INTERVAL", PROPERTIES( "datetime-lower"="1970-01-01 00:00:00", "datetime-upper"="1980-01-01 00:00:00", "sharding-seconds"="86400" )) ); SUCCESS testdb=> create table t100 ( vkey int4 , pkey int4 , c0 numeric , colocated_key timestamp ); CREATE TABLE testdb=> INSERT INTO t100 (vkey, pkey, c0, colocated_key) VALUES (2, 12000, -479737441.3639, TIMESTAMP '1973-06-03 10:30:01'); ERROR: Please check your sharding conditions 'ShardingConditions(conditions=[ShardingCondition(values=[], startIndex=0)], sqlStatementContext=org.apache.shardingsphere.infra.binder.context.statement.dml.InsertStatementContext@5f864204, rule=org.apache.shardingsphere.sharding.rule.ShardingRule@1ec5ef0e, subqueryContainsShardingCondition=true)' to avoid same record in table 't100' routing to multiple data nodes. testdb=> insert into t100 (vkey, pkey, c0, colocated_key) values (2, 12000, -479737441.3639, make_timestamp(1973, 6, 3, 10, 30, 1)); ERROR: Please check your sharding conditions 'ShardingConditions(conditions=[ShardingCondition(values=[], startIndex=0)], sqlStatementContext=org.apache.shardingsphere.infra.binder.context.statement.dml.InsertStatementContext@87683f2, rule=org.apache.shardingsphere.sharding.rule.ShardingRule@79a00d3b, subqueryContainsShardingCondition=true)' to avoid same record in table 't100' routing to multiple data nodes. testdb=> insert into t100 (vkey, pkey, c0, colocated_key) values (2, 12000, -479737441.3639,'1973-06-03 10:30:01'); INSERT 0 1 ``` ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. [ss_postgres.zip](https://github.com/user-attachments/files/24228864/ss_postgres.zip) run `docker compose up -d` in this file.
