无法使用#

Question

我尝试在https://phekb.org/phenotype/type-2-diabetes-mellitus中使用“原始T2DM病例算法的eMERGE OMOP MS SQL版本”。当我运行代码时，出现此错误：“‘#’处或附近存在语法错误”。问题应该出在这里：

SELECT event_id, person_id, start_date, end_date, 
     op_start_date, op_end_date, visit_occurrence_id

INTO #qualified_events

FROM 
(
  select pe.event_id, pe.person_id, pe.start_date, pe.end_date,
    pe.op_start_date, pe.op_end_date, 
    row_number() over (partition by pe.person_id order by pe.start_date ASC) as ordinal, 
    pe.visit_occurrence_id
  FROM primary_events pe

我尝试制作临时表而不是使用“#”，但错误存在。任何建议都会对我有很大帮助。谢谢。

如果是MySQL，则这样写：

CREATE TEMPORARY TABLE IF NOT EXISTS temp_qualified_events AS (

  select pe.event_id, pe.person_id, pe.start_date, pe.end_date,
    pe.op_start_date, pe.op_end_date, 
    row_number() over (partition by pe.person_id order by pe.start_date ASC) as ordinal, 
    pe.visit_occurrence_id
  FROM primary_events pe
);

“#”前缀用于 MS SQL 临时表。
