问题 Good Afternoon to All, I have a question concerning on SQL Queries. is it possible to use an array as a parameter to a query using the "IN" command? for example, int x = {2,3,4,5} UPDATE 'table_name' set 'field' = data WHERE field_ID IN (x) the reason I am asking this is to avoid an iterative SQL Statement when I have to update data in a database. I also thought of using a for each statement in for the UPDATE Query but I don't know if it will affect the performance of the query if it will

(I have no control over the use/non use of CSV lists within database fields, working with what i have) and I have done a little testing and found that you can do the following: Where database_field In (#CSV_list#) If database_field equalled 2 and CSV_list equalled 1,2,3,4 this would return true as the value of 2 was found within the CSV list.

mysql force order of results found to match order of IN clause

问题 This question is different to a commonly asked question about ordering the final results by the IN clause. I would like to force the results returned by the query that contains the IN clause, to match the order of the IN clause. This is the original question that I am working from. I'd like to alter the query below so that a row containing progress=2 occurs before progress=4 and progress=7 for each session_id when ordering the formation_page_hits table by datetime . Here is the current query:

Using IN clause in a native sql query

由 ☆樱花仙子☆ 提交于 2019-11-29 03:42:55
We are trying to dynamically generate an IN clause for a native sql query to return a JPA entity. Hibernate is our JPA provider. Our code looks something like this. @NamedQuery( name="fooQuery", queryString="select f from Foo f where f.status in (?1)" ) .... Query q = entityManager.createNamedQuery("fooQuery"); q.setParameter(1, "('NEW','OLD')"); return q.getResultList(); This doesn't work, the in clause does not recognize any of the values passed in via this manner. Does anyone know of a solution to this problem? topchef JPA supports named list parameters, in your case: @NamedQuery( name=
