```SELECT * FROM linkis_ps_job_history_group_history
id = ${id}
and submit_user = ${umUser}
and engine_type = ${engineType}
and created_time >= ${startDate} AND created_time <![CDATA[<=]]>${endDate}
and
${element}
ORDER BY linkis_ps_job_history_group_history.created_time DESC
```
在你提供的SQL查询中,${element}
似乎是一个可变的占位符,用于动态地添加条件。如果你不希望element
被自动识别为请求参数,同时又不能直接删除,你需要确保在处理这个查询时,对element
进行适当的处理。以下是一些可能的解决方案:
element
变量是否为空或者是否需要包含在查询中。如果element
是空的或者不需要,你可以直接忽略它,或者用一个不会影响查询的无操作(如1 = 1
)替换它。python
element_condition = "${element}" if your_element_variable else "1 = 1"
sql_query = f"SELECT * FROM linkis_ps_job_history_group_history \
WHERE id = {id} \
AND submit_user = {umUser} \
AND engine_type = {engineType} \
AND created_time >= {startDate} \
AND created_time <![CDATA[<=]]> {endDate} \
AND {element_condition} \
ORDER BY linkis_ps_job_history_group_history.created_time DESC"
str.format()
来构造SQL查询,确保element
只在有值时添加。python
query_template = """
SELECT * FROM linkis_ps_job_history_group_history
WHERE id = {}
AND submit_user = {}
AND engine_type = {}
AND created_time >= {} AND created_time <![CDATA[<=]]> {}
AND {}
ORDER BY linkis_ps_job_history_group_history.created_time DESC
"""
params = [id, umUser, engineType, startDate, endDate, your_element_variable or "1 = 1"]
sql_query = query_template.format(*params)
element
是否存在,动态构建SQL查询字符串。这样,当element
为空或不需要时,就不会出现在SQL中。python
conditions = ["id = %s", "submit_user = %s", "engine_type = %s",
"created_time >= %s AND created_time <![CDATA[<=]]> %s"]
query_params = [id, umUser, engineType, startDate, endDate]
if your_element_variable:
conditions.append(your_element_variable)
query_params.append(your_element_variable)
sql_query = "SELECT * FROM linkis_ps_job_history_group_history WHERE " + " AND ".join(conditions) + " ORDER BY linkis_ps_job_history_group_history.created_time DESC"
确保在实际应用中,你遵循SQL注入防护的最佳实践,比如使用参数化查询,防止恶意输入破坏你的数据库。
