I'm working on an Azure web app. Using the entity framework to fetch the result.
Everything is working fine. All queries are working as expected.
But the following one throwing the SQL connection timeout error. Most of the time it works fine but doesn't know when it starts giving the error and keep this error for more than 24 hours.
var logsCount = context.Logs.Where(l => l.StartDate >= startDate && l.StartDate <= endDate)
.GroupBy(l => l.KeywordID)
.ToDictionary(l => l.Key, l => l.Count());
I believe it's not an issue with the query because it keeps running fine for many days and starts giving problem suddenly.
It starts working fine itself. Not sure, why it's happening?
Can it be anything related to database or server only?
Please try creating an index like the following using a tool like SQL Server Management Studio:
CREATE INDEX IX ON [YourTable] (StartDate, KeywordID) INCLUDE
( list all columns returned separated by comma )

Im using adonis.js , I have the following query... When I make a request to my API this is the first database query. I get the above error only once every hour or so. Im using render.com to host my API and postgres database. I believe adonis.js uses knex and this maybe the problem but I am not sure.
const api_key_check = await database
.table('client_api_key')
.where('api_key', api_key_encoded)
.first()
It looks like knex have an open issue since node's 12 release.
Follow this thread and see if some proposed solution works for you:

I have a Mirth (v3.10) Database Reader channel source that grabs some test records (from an SQL Server source) using the query...
select *
from [mydb].[dbo].[lab_test_MIRTHTEST_001]
where orc_2_1_placer_order_number
in (
'testid_001', 'testid_002', 'testid_003'
)
Even though the channel appears to function properly and messages are getting written to the channel destination, I am seeing SQL errors in the server logs in the dashboard when deploying the channel:
[2020-12-16 08:16:28,266] ERROR (com.mirth.connect.connectors.jdbc.DatabaseReceiver:268): Failed to process row retrieved from the database in channel "MSSQL2SFTP_TEST"
com.mirth.connect.connectors.jdbc.DatabaseReceiverException: com.microsoft.sqlserver.jdbc.SQLServerException: The index 1 is out of range.
at com.mirth.connect.connectors.jdbc.DatabaseReceiverQuery.runPostProcess(DatabaseReceiverQuery.java:233)
at com.mirth.connect.connectors.jdbc.DatabaseReceiver.processRecord(DatabaseReceiver.java:260)
...
I can run this query fine in the SQL Server Mgmt Studio itself (and the messages seem to be transmitting fine), so not sure why this error is popping up but am concerned there is something I'm missing here.
Anyone with more experience know what is going on here? How to fix?
The issue looks to be in the post-process SQL section of the Database Reader, so it makes sense that the messages appear to be working.
Did you intend to enable the post-process section at the bottom of your source tab?
Kindly share the code that you are using to process data in the result set. In the meantime, you can consider the code below as a staring point. You can place this in Javascript transformer step in the source connector of your channel.
//Declaring variables to hold column values returned from the result set
var variable1;
var variable2;
//defining the sql read command
var Query = "select * from [mydb].[dbo].[lab_test_MIRTHTEST_001]";
Query += " where orc_2_1_placer_order_number in";
Query += " ('testid_001', 'testid_002', 'testid_003')";
var result = dbconn.executeCachedQuery(Query);
//where dbconn is your database connection string
//looping through the results
while(result.next())
{
variable1=result.getString("variable1");
variable2 = result.getString("variable2");
}
//optionally place the returned values in a channel map for use later
$c('variable1',variable1);
$c('variable2',variable2);
I have very simple SSIS package which brings 8 columns from PostgreSQL into SQL server. There are only 10 rows feeding through. Now requirement changed by adding another
- join
- with extra column to bring back.
- Also one where clause condition to be removed.
When changed and preview using OLE DB source editor it throws error 'Value does not fall within the expected range'
script runs successfully in PostgreSQL within 40 sec(though it should not take that long).
In 'OLE DB source editor:
When adding Join - it previews(successfully)
when adding Join and bringing column - it previews (successfully)
when adding Join, bringing column and removing condition ( condition let it bring 149 records instead of 10 ) - (throws error)
I guess it is very basic error and someone with experience will be able to spot it quickly. Will be very thankful for kind and prompt response..
I have checked datatype for new column source and destination and it matches. character (255)
I have run script using PGAdmin 4 and it runs successfully in PostgreSQL.

I am having an issue with a date literal not returning any results when I run an SOQL query. The query is as follows:
Select * From dbo.Case WHERE CreatedDate = YESTERDAY
With the query, I would like to obtain case data from the previous day. I know there is data available that was created the previous day. The results of the query when I preview it, though, are an empty set with no error message.
A different wrinkle that makes this not quite a strict SOQL issue is that I am trying to use this query as an SQL command on an ADO.NET connection using the CData ADO.NET driver to connect to a SalesForce.com instance. My goal is to be able to build SSDT packages that will allow me to stage the data from SalesForce into our SQL Server for processing there.
I have similar issues using the LAST_N_DAYS date literal as well.
I believe I should be using SOQL to query in the SQL command text field for the ADO.NET source connection but I am not 100% sure about that. I know for certain that I cannot use T-SQL because it does not recognize the GETDATE().
Any guidance on how to pull the records from Case for the previous day or where the query I am using might be wrong would be greatly appreciated.
Found an answer. The following SQL command will pull the data from the previous day:
Select * From dbo.Case Where CreatedDate = 'YESTERDAY'
The single quotes evaluate the yesterday date literal as expected.
Likewise, the following SQL statement will get the last 30 days of data.
Select * From dbo.Case Where CreatedDate = 'LAST_N_DAYS:30'
Thanks to anyone who researched and attempted the question! :)
After over one day of finding & trying to solve issue its time to ask here.
We use Firebird over years (around 6) and with current version 2.5.2 updated long time ago we met the problem with unable to UPDATE statement.
SQL statement is OK, even "where" condition is used with primary key.
Problem: update is going to stuck after click on: execute
a) from php script it return Internal server error 500
b) directly from Flamerobin or IBQ its freezes and not responding at all
hint: SQL which wasnt working is working right after clean firebird (stop & start) but after a while its going to stuck again
hint: selects are or, problem is only with UPDATE
hint: I did all described here https://www.ibphoenix.com/resources/documents/how_to/doc_5
(redump of database file which was giving me errors on gfix -v -full)
after redump there was no error but problem occurs
hint: We have more servers running the same configuration with more database files but this happen only for one table in one DB file on one server.
After some investigation I finally got this from fbtrace:

Im out of ideas what to check, almost lost. Just want let you know that we didnt change anything in FB or server configuration.
Thanks for any usefull help.
Everything was caused by one of many script running in background (from cron) taking open transaction without committing for few hours.
Its OK back again.
