【问题描述】*：
我使用EFCore来操作达梦数据库。
有个业务需要操作两张表，执行的SQL如下：
表一：

SELECT
	 CASE
    WHEN EXISTS (
		
        SELECT
			 1
        
		FROM "LANGUAGES" AS "l"
        
		WHERE "l"."TenantId" = 1 /* :__language_TenantId_0 */ AND
			 "l"."Name" = 'ja' /* :__language_Name_1 */)
		 THEN TRUE
    ELSE FALSE
END
SELECT TOP(1) "r"."Id",
              "r"."ConcurrencyStamp",
              "r"."CreationTime",
              "r"."CreatorUserId",
              "r"."DeleterUserId",
              "r"."DeletionTime",
              "r"."Description",
              "r"."DisplayName",
              "r"."HospitalID",
              "r"."IsDefault",
              "r"."IsDeleted",
              "r"."IsStatic",
              "r"."LastModificationTime",
              "r"."LastModifierUserId",
              "r"."Name",
              "r"."NormalizedName",
              "r"."TenantId"
FROM   "ROLES" AS "r"
WHERE  ("r"."TenantId" IS NULL)
       AND "r"."Name" = 'admin'

表二：

INSERT INTO "ROLES" (
	"ConcurrencyStamp",
	 "CreationTime",
	 "CreatorUserId",
	 "DeleterUserId",
	 "DeletionTime",
	 "Description",
	 "DisplayName",
	 "HospitalID",
	 "IsDefault",
	 "IsDeleted",
	 "IsStatic",
	 "LastModificationTime",
	 "LastModifierUserId",
	 "Name",
	 "NormalizedName",
	 "TenantId")

VALUES (
	'0f491f43-557a-4b2a-b6cb-2bb83f8f545f' /* :p0 */,
	 '2024-06-28T16:26:12' /* :p1 */,
	 NULL /* :p2 */,
	 NULL /* :p3 */,
	 NULL /* :p4 */,
	 NULL /* :p5 */,
	 'admin' /* :p6 */,
	 0 /* :p7 */,
	 1 /* :p8 */,
	 0 /* :p9 */,
	 1 /* :p10 */,
	 NULL /* :p11 */,
	 NULL /* :p12 */,
	 'admin' /* :p13 */,
	 'ADMIN' /* :p14 */,
	 NULL /* :p15 */)
;
SELECT
	 "Id"

FROM "ROLES"

WHERE sql%ROWCOUNT = 1 AND
	 "Id" = scope_identity(
		)
	;	

执行这些操作使用的是同一个DbContext实例，在执行到表二的操作时，报告了 Parameter '__LANGUAGE_TENANTID_0' not found in the collection 错误。
可以看到**__LANGUAGE_TENANTID_0**是操作表一是使用的参数，我在表一的操作按理来说已经结束了，为什么在操作表二时报告了缺少执行表一时所需的参数呢？
