C＃ 使用SqlSugar Updateable系统报错无效数字，如何解决？求指导！

代码：

 for (int i = 1; i <10; i++)            {                var UpdateSN = new WF_UNITINFO();                {                    UpdateSN.ID = "202207200000" + i;                    UpdateSN.UNITID = "DEV202207200000" + i;                    UpdateSN.UNITID56 = "DEV202207200000" + i + "202000000001TEST0" + i;                }                db.Updateable<WF_UNITINFO>(UpdateSN).UpdateColumns(it => new { it.ID, it.UNITID, it.UNITID56})                    .Where(it=>it.UNITID == "DEV202207200000" + i).ExecuteCommand();            }

(it=>it.UNITID == "DEV202207200000" + i)
使用Convert强制转换也一样报错

系统报错：

Oracle.ManagedDataAccess.Client.OracleException  HResult=0x80004005  Message=ORA-01722: 无效数字  Source=Oracle Data Provider for .NET, Managed Driver  StackTrace:   at SqlSugar.AdoProvider.ExecuteCommand(String sql, SugarParameter[] parameters)   at SqlSugar.UpdateableProvider`1.ExecuteCommand()   at SqlSugar.OracleUpdateable`1.ExecuteCommand()   at Queryable.Program.Main(String[] args) in D:\C#\Practice02\Queryable\Program.cs:line 114
