[英]How to bind query parameters in hibernate if query is dynamic statement?
I am having a dynamic query as : 我有一个动态查询:
DECLARE @LOERangeMin int =0 ;
DECLARE @LOERangeMax int = 0;
DECLARE @CycleStartStatus nvarchar(500) = :param1;
DECLARE @CycleEndStatus nvarchar(500) = :param2;
DECLARE @Team nvarchar(100) = NULL;
DECLARE @ReportStartDate datetime = NULL;
DECLARE @ReportEndDate datetime = GETDATE();
select min([Cycle Time]) AS AvgMinCycleTime,max([Cycle Time]) AS AvgMaxCycleTime,AVG([Cycle Time]) AS AvgCycleTime
from EpicTable where EpicStartStatusName = @CycleStartStatus and EpicEndStatusName = @CycleEndStatus
I am preparing Query object by passing this query as a string as : 我通过将此查询作为字符串传递来准备Query对象:
Query que = session.createSQLQuery(queryString);
In this I want to set CycleStartStatus and CycleEndStatus using que.setParameter("param1",CycleStartStatus); 在这里我想使用que.setParameter(“param1”,CycleStartStatus)设置CycleStartStatus和CycleEndStatus; and que.setParameter("param2",CycleEndStatus); 和que.setParameter(“param2”,CycleEndStatus);
I tried this way but it is showing "org.hibernate.QueryParameterException: could not locate named parameter [param1]". 我试过这种方式,但它显示“org.hibernate.QueryParameterException:找不到命名参数[param1]”。 So can anyone please help me out how can I do this? 所以有人可以帮助我,我该怎么做?
You must place the HQL parameters using this notation: :paramName
. 您必须使用以下表示法放置HQL参数:paramName
。 Like this: 像这样:
select min([Cycle Time]) AS AvgMinCycleTime,
max([Cycle Time]) AS AvgMaxCycleTime,
AVG([Cycle Time]) AS AvgCycleTime
from EpicTable where EpicStartStatusName = :param1
and EpicEndStatusName = :param2
And then: 接着:
Query que = session.createSQLQuery(queryString);
que.setParameter("param1",CycleStartStatus);
que.setParameter("param2",CycleEndStatus);
