店铺流程：CREATE DEFINER=`newdb`@`%` PROCEDURE `GetMaximumIDsCount`(IN AppID INT,IN isBurnCenter INT,IN BurnCenterID INT)BEGIN    IF isBurnCenter = 1 THEN    SELECT MAX(CAST(b.hospitalid AS SIGNED))    FROM tblhosipital b    WHERE b.appId = AppID AND b.burncenterid IS NULL;    END IF;    IF isBurnCenter = 0 THEN    SELECT MAX(CAST(h.hospitalid AS SIGNED))    FROM tblhosipital h    WHERE h.appId = AppID AND h.burncenterid <> '' AND h.burncenterid = BurnCenterID;    END IF;END从 ApplicationDbContext 调用（代码优先）public virtual ObjectResult<long?> GetMaximumIDsCount2(Nullable<int> appID, Nullable<int> isBurnCenter, Nullable<int> burnCenterID)        {            var appIDParameter = appID.HasValue ?                new ObjectParameter("AppID", appID) :                new ObjectParameter("AppID", typeof(int));            var isBurnCenterParameter = isBurnCenter.HasValue ?                new ObjectParameter("isBurnCenter", isBurnCenter) :                new ObjectParameter("isBurnCenter", typeof(int));            var burnCenterIDParameter = burnCenterID.HasValue ?                new ObjectParameter("BurnCenterID", burnCenterID) :                new ObjectParameter("BurnCenterID", typeof(int));            return ((IObjectContextAdapter)this).ObjectContext.ExecuteStoreQuery<Nullable<long>>("GetMaximumIDsCount @AppID, @isBurnCenter, @BurnCenterID", appIDParameter, isBurnCenterParameter, burnCenterIDParameter);        }获取异常：您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，了解在第 1 行的“GetMaximumIDsCount @AppID、@isBurnCenter、@BurnCenterID”附近使用的正确语法
