Turns out, it uses a connection pool by HikariCP. The default behavior of the maxLifetime and idleTimeout configurations are causing the reconnection. Setting both configurations to 0 disables them and removes the reconnecting issue. Shoutout to this comment for helping me understand my problem.

This should be easy with a NOT EXISTS subquery. Assuming the tables are as you show them: selact a.* from a where "Current Stock" = 0 and not exists ( select * from b where b.id = a.id and "Current Stock" > 0 ) ;

Maximum SQL Server memory set to 12 GB, but it still goes over 12 GB. How do I prevent SQL Server going over max memory limit?

My problem is that my server is going over the set 12GB memory and if things like CLR/Full Text/Server exe files taking additional memory. What Denny Cherry wrote is true for SQL Server version from 2005 to 2008 r2. From SQL Server 2012 onward there was considerable change in SQL Server memory allocation. Memory for SQLCLR is allocated from max server memory setting in SQL Server 2012 not outside of it. BOL says that from SQL Server 2012 onward Max server memory controls SQL Server memory allocation, including the buffer pool, compile memory, all caches, qe memory grants, lock manager memory, and CLR memory (basically any “clerk” as found in dm_os_memory_clerks). Memory for thread stacks, memory heaps, linked server providers other than SQL Server, or any memory allocated by a “non SQL Server” DLL is not controlled by max server memory. Prior to SQL 2012, the buffer pool both “managed” memory and was a consumer of memory for database pages. It’s management of memory meant it allocated 8Kb pages of memory for other consumers like plan cache. Roll forward to 2012+, the buffer pool is a pure consumer of memory from SQLOS which manages all of the memory. Please tell me how to configure SQL Server, so it does not go over the set max limit. This is not possible. In SQL Server 2012 if you are not using third party linked servers providers or if any DLL which is not Microsoft provided is not loaded in SQL Server address space there is less chance that SQL Server can consume memory outside max server memory setting. But the fact is you cannot control SQL Server not to utilize memory outside buffer pool. That is how it is designed.

Your issue is that you have defined a recursive function ... the function is calling itself. The logic that exists in it currently would result in a stack dump with OUT OF MEMORY error (or something along those lines, at least) if it didn't give you the error of "table already exists" to begin with.. CREATE OR REPLACE FUNCTION f_copy_tbl(_tbl regclass, _newtbl text) RETURNS void AS $func$ BEGIN -- --Now populate `parts1` table with `parts` table's content... SELECT f_copy_tbl('parts','parts1'); --- THIS IS THE OFFENDING LINE HERE .. REMOVE IT INSERT INTO parts1 SELECT * FROM parts; -- END $func$ LANGUAGE plpgsql VOLATILE; Your order of SQL should be as such: CREATE OR REPLACE FUNCTION my_func(param1 VARCHAR, param2 VARCHAR) RETURNS VOID AS $$ DECLARE var1 VARCHAR; BEGIN -- DO STUFFS HERE FOR FUNCTION END; $$ LANGUAGE plpgsql; -- THE ABOVE DEFINES THE FUNCTION -- THE BELOW EXECUTES THE FUNCTION SELECT my_func('val1', 'val2'); -- THIS ONE LINE WILL EXECUTE ALL SQL DEFINED INSIDE THE FUNCTION The function definition is what is between the dollar quoting..

You're having to sort, because you don't have an index on parent_id.. "comment_pkey" PRIMARY KEY, btree (id) "index_comment_id_parent_id" UNIQUE, btree (id, parent_id) This is also redundant. There is no need for a UNIQUE index on on (id, parent_id) when you're already UNIQUE on id. Solution: Drop the index on id, parent_id, create an index on parent_id. Moreover, you're having to sort on ct.created_date DESC. This is because your only index is on (website_page_id, parent_id, deleted_date, created_date DESC) That's a huge index. It's also not useful here at all. Solution: Drop this overly compound index, and create one on ct.created_date DESC Don't forget to vacuum analyze. Note this query won't ever be fast. You're essentially processing 1000010 rows even if you only need 10. Consider not asking for the hierarchy for the whole database to get 10 rows.

(I accept that this is not quite technically accurate, but is close enough) The error message is telling you that the database was created in a higher version than the one you are trying to open it in. All the database files are marked with this version. This database was created in v12, you're trying to open it in v11. This will not work. There is nothing you can do except use a v12 database home to mount/open the database. It is possible to create a database in v12 which is compatible with v11, by using the COMPATIBLE parameter. This tells the database engine what version the database should remain compatible with, and what database features to use.

Yes, PostgreSQL is fully network aware. You can put it on a separate machine or not, this all depends on how you use it, so you will need to state your requirements, type and volume of data, etc. See for example https://www.postgresql.org/docs/current/static/runtime-config-connection.html and https://www.postgresql.org/docs/current/static/ssl-tcp.html For development purposes, you can install it on your own machine to develop your programs and later just move your application to use the production database.

It's actually very simple. Start from the wanted date and descend the dates until you find the first row. If it's 'start' then you are inside an interval. If it's 'stop', you are not: select ( select startstop from mytable where mydate = '2017-02-07' and startstop = 'start' or mydate < '2017-02-07' order by mydate desc limit 1 ) = 'start' as result ; The complicated WHERE is for dealing with the inclusive date ranges. If inclusive-exclusive were used, the condition would be simper. A similar way - perhaps a bit more clear - would be: with ct as ( select mydate, startstop from mytable where mydate

Your query can be collapsed to the single JOIN without subselects: UPDATE student_activity AS c LEFT JOIN student_activity AS b ON c.student_id = b.student_id AND c.class_type = b.class_type AND c.date > b.date WHERE b.date IS NULL SET c.first_attendance = c.date ; I hope your table student_activity have the index (student_id, class_type, date)

Check out this site for SQL Build Numbers. It is a comprehensive list of build numbers for SQL Server. https://sqlserverbuilds.blogspot.ca/#sql2014 According to this list of build numbers, you will first have to apply Service Pack 1 for SQL Server 2014 which will bring you to 2014.120.4100.1. Then you will have to apply MS15-058 which will bring you to 2014.120.4213.0 as requested. The blog post will have links to download the service pack and patch. Obviously, with any upgrade, please take care. Make sure you have proper backups of your databases before hand. If a VM, taking a VM snapshot before the upgrade is a good idea. While I do not expect you to have issues running these installs, it is best to always have a backup ahead of time. Additionally, please make sure you read the documentation pertaining to each of these updates so you can be fully aware of what they will do to your environment.

I would try the following statement to retrieve the owner of the object: select owner, object_name, object_type from ALL_OBJECTS where object_name = 'MEMBER'; Referenced here Then depending on the result(s) returned you would adjust your statement to something like this: SELECT * FROM .MEMBER; ...and replace with the owner that was returned in the first statement.

I don't know anything about node.js and sequelize.js, so I can't help you that way.But I can leave you a model of the SQL query class in PostgreSQL that allows you to group the records that way. And then you can adjust the query according to your need.Assuming a table tbl with the following structure and data:create table tbl ( fecha date not null, valor int not null ); insert into tbl (fecha, valor) values ('2016-01-01', 10), ('2016-01-01', 20), ('2016-01-01', 30), ('2016-02-01', 40), ('2016-02-01', 50); The following query, using the function https://www.postgresql.org/docs/current/static/functions-aggregate.html returns the results as requested:select fecha, string_agg(valor::text, ' ' order by valor) from tbl group by fecha; http://rextester.com/TTUHB35745

Yeah, you can use a few. JOINAnd there are two options in your case.That's the request. JOIN by comments.user_id:select u.username, t.name_task, t.description, t.state, c.body_comment from tasks as t inner join comments as c on t.code_task = c.code_task inner join users as u on c.user_id = u.user_id; That's it. tasks.user_idselect u.username, t.name_task, t.description, t.state, c.body_comment from tasks as t inner join comments as c on t.code_task = c.code_task inner join users as u on t.user_id = u.user_id;

Two leads: If "jiradb.public.propertyentry" is a materialized view, you might be running into a bug that was fixed with the release of 9.4.17 on 2018-03-01. The release notes: Repair pg_upgrade's failure to preserve relfrozenxid for materialized views (Tom Lane, Andres Freund) This oversight could lead to data corruption in materialized views after an upgrade, manifesting as “could not access status of transaction” or “found xmin from before relfrozenxid” errors. The problem would be more likely to occur in seldom-refreshed materialized views, or ones that were maintained only with REFRESH MATERIALIZED VIEW CONCURRENTLY. If such corruption is observed, it can be repaired by refreshing the materialized view (without CONCURRENTLY). The last line also hints how to repair this. Or, if you upgraded from Postgres 9.2 or older, this other issue resulting in cannot freeze committed xmax may be yours: https://www.postgresql.org/message-id/E1erVTy-0005Lp-8p%40gemulon.postgresql.org https://www.postgresql.org/message-id/CAPYLKR6yxV4=pfW0Gwij7aPNiiPx+3ib4USVYnbuQdUtmkMaEA@mail.gmail.com Fixed, but not released, yet. Should be in 9.4.18.
