描述：
Sqlsever数据库中自带函数SYSDATETIME()在金仓数据库中对应的是SYSTIMESTAMP。
错误信息：
java.sql.SQLException
: [KingbaseES Server]ERROR: 函数 SYSDATETIME() 不存在 Line 1 at SQL statement
HINT: 不能根据所提供的名称和参数类型找到与之匹配的函数。你可以增加显式的类型转换。

解决办法：
编写语句时使用对应的函数替换即可（红色部分是需要修改的）。
Sqlserver写法：
“INSERT INTO TBL_WORKFLOW_AGENT_LOG (id,workflowId,processDefinitionId,processInstanceId,taskDefinitionId,taskId,beagenterId,agenterId,agentDateTime,creater,createDateTime)values(NEWID(),'”+wid+”‘,'”+rs1.getString(“PROC_DEF_ID_”)+”‘,'”+rs1.getString(“PROC_INST_ID_”)+”‘,'”+rs1.getString(“TASK_DEF_KEY_”)+”‘,'”+rs1.getString(“EXECUTION_ID_”)+”‘,'”+beAgenterId+”‘,'”+agenterId+”‘,
SYSDATETIME()
,”,
SYSDATETIME()
)”;
改为：
“INSERT INTO TBL_WORKFLOW_AGENT_LOG(id,workflowId,processDefinitionId,processInstanceId,taskDefinitionId,taskId,beagenterId,agenterId,agentDateTime,creater,createDateTime)values(NEWID(),'”+wid+”‘,'”+rs1.getString(“PROC_DEF_ID_”)+”‘,'”+rs1.getString(“PROC_INST_ID_”)+”‘,'”+rs1.getString(“TASK_DEF_KEY_”)+”‘,'”+rs1.getString(“EXECUTION_ID_”)+”‘,'”+beAgenterId+”‘,'”+agenterId+”‘,
SYSTIMESTAMP
,”,
SYSTIMESTAMP
)”
