Solved Openquery Is Taking A Long Time In Sql Server But Runs In 2 Sec I have one query that taking too long, that is 60 minutes. i am programmer but i am not quite sure if all the table are indexes out. here is the query, any table that ends with v is view: select. My source and target tables are identical but constantly in flux as cdc is applying updates, inserts, and deletes from source to target constantly. the issue we have is to identify those situations when the cdc tool does not replicate some database log activity from oracle to synapse. the way we are doing this.
Sql Query Execution Takes More Time Microsoft Q A How to debug oracle long running query execution is taking more than 24 hours with objecthistory as ( select temp.object key, max (temp.source event date) as maxsed, temp.user name, temp.event date from ( select max (object key) as object key, user name, event date, source event date from v aaa group by object history key, user n. The below 2 queries are running too slow, 1st one takes ~10 hours (47000 seconds), the second one takes ~1 hr (4300 seconds). i tried using parallel hints within the queries, though the execution plan looks good query still takes hours to execute. Below is the select query which takes 1515 seconds to finish. can some one help me improve the query performance by looking into the execution plan provided below. I'm encountering an "issue" (at least a strange slow behavior) with a new installation of oracle 12c on windows server 2019, with this query which takes at least 5 minutes to complete:.
Long Running Query Azure Sql Server Microsoft Q A Below is the select query which takes 1515 seconds to finish. can some one help me improve the query performance by looking into the execution plan provided below. I'm encountering an "issue" (at least a strange slow behavior) with a new installation of oracle 12c on windows server 2019, with this query which takes at least 5 minutes to complete:. This is to ask some suggestion about a query which is infrequently taking minutes >hours time to finish (mostly it is fast). this is the query generated by the execute query; procedure in oracle forms compiled in forms 11g and running on oracle 11g database. I could set this query up in one oracle database and make it run slow and make it run fast in another. there are many factors that determine how the database resolves the query, object statistics, sys schema statistics, and parameters, as well as server performance. We got complaint from user stating a query running longer and i see the query is big one, but after running the multiple parts of the query manually , i see below query which is part of main query is running for more than hours itself when we tested it from sqlplus prompt, it appears its struggling for fetching data and pass it to the client. There are a lot of reasons why an oracle query could take so long, but in this case i would guess: 1 the inner select (select objid from table1 and select objid from table2) will have to be evaluated on each row.
