zhangfei 9c3e603b94 Fix Bug #443: 手术计费:点击签发耗材时异常报错
当手术计费弹窗中点击"签发"耗材时,因耗材的locationId(发放库房)为空导致后端异常。
在DoctorStationAdviceAppServiceImpl.handDevice方法中,当locationId为null时,使用登录用户的科室ID作为默认值,
与NurseBillingAppService中的处理方式保持一致。

-- 移除 adm_practitioner 表中 create_by 列的 NOT NULL 约束
-- 用于解决 org.postgresql.util.PSQLException: ERROR: null value in column "create_by" of relation "adm_practitioner" violates not-null constraint
-- 在PostgreSQL中NOT NULL约束实际上是列的一个属性而不是命名约束
-- 因此我们使用 ALTER COLUMN ... DROP NOT NULL 来移除它
-- 可选:先查看当前表结构及约束信息
-- 注意:\d 命令仅在 psql 中有效,在脚本中不能使用

-- 移除 create_by 列的 NOT NULL 约束
ALTER TABLE "public"."adm_practitioner"
ALTER COLUMN "create_by" DROP NOT NULL;
-- 可选:如果需要,可以同时移除默认值
-- ALTER TABLE "public"."adm_practitioner"
-- ALTER COLUMN "create_by" DROP DEFAULT;
-- 提示执行此脚本后create_by 列将允许 NULL 值
-- 这将解决插入数据时因缺少 create_by 值而导致的违反非空约束错误
