Hello, Following abnormally high costs when using serverless sql on September 9 and 10, I noticed that the cluster sometimes stays on for an hour even though it's not receiving any new requests, and that the auto-stop is set to 5 minutes of inactivit...
Hi @EmmaP Have you checked the monitoring tab? Any active sessions, queued queries that could block cluster from terminating?Monitor a SQL warehouse - Azure Databricks | Microsoft Learn

I'm using a SQL warehouse with autostop after 5 minutes of inactivity. However, the cluster is constantly activating and deactivating without any explanation. There are no queries being executed, and I can't identify any reasons why it is happening,...
Hi @msolcuadrado ,In your case I would try to contact directly with databricks support team. This is a serious issue and I feel your pain. They should help you pinpoint an excat cause + maybe you'll get a refund
According to the official Databricks documentation on GCP, I should have the ability to deploy a serverless SQL warehouse inside Databricks. Following the documentation, it is requested to turn on Serverless SQL warehouses (On), but there is nothing ...
Hi @LeoRickli ,The step to turn on turn on Serverless SQL warehouses (On) is only required if your account was created before March 28, 2022. Serverless compute is enabled by default for your workspaces created after that date.And did you do 1 step ...
We are experiencing the following issues.Description:I encountered an issue while executing a Spark SQL query in Databricks, and it seems to be related to the query optimization phase. The error message suggests an internal bug within Spark or the Sp...
Hi,I'm receiving the error Incorrect syntax near '=' when I run simple queries like the example below. This only happens when I use a column created using a CASE statement in the WHERE clause. I can use any other column in the WHERE clause, includi...
What jumps out to me at first is the backticks on `Peak Vertical Force / BW`, but I'm assuming that's just a column name and not an attempt at division.Next that jumps out is TestType and TestTypeName being aliased as testType and testTypeName- spark...
I was trying to install a personalized .whl file located in the "shared" folder but I'm obtaining this error:org.apache.spark.SparkException: Process List(/bin/su, libraries, -c, bash /local_disk0/.ephemeral_nfs/cluster_libraries/python/python_start_...
Hi,I'm using the REST API for SQL Warehouse in order to execute queries. I have experienced multiple times that query validation fails over the REST API, while executing the same query in the Databricks UI on the same cluster succeeds. An example: [P...
Had to try for myself and it seems the sql execution context in the REST API is different than that of an *.sql script, notebook or query made against an sql warehouse through the ui. The error stems from the fact that the SET command can also be use...
Dear community,Im trying to setup a connection to get data from a catalog / underlying tables from that catalog and load it directly into MS Access 365 (latest version). Is it possible to do this? What would be the best practice? Thanks,Bram
Hi! @jakubk:I have the same issue that I cannot achieve via access is to change to tables from inside the unity catalog, I can only see tables in the hive_metastore and cannot change the default / or to any other catalog. The same DSN is working fine...
Hello. Please forgive me if this is not the right place to ask, but I'm having issues with databricks' statement execution api. I'm developing Haskell client for this api.I managed to implement most of it, but I'm running into issues with using named...
@jhrcekagreed, your original issue is still a bug. I created a support case with Databricks Support for it, we'll see what they say.
Hello we are currently facing a challenge with writing data from a local machine to Delta tables. While small data loads (e.g., 100 Rows) work without any issues, attempting to write larger batches (around 1,000 Rows) results in an exception. the iss...

I have a query using LCA. When referencing another table that has a column with the same name as the column used as LCA, the behavior of the query changes and it starts referencing the table column instead of the column that is already in the select ...
Hi @Kaniz_Fatma,we had the same problem as @paulocorrea.That's why it would be correct for to me to throw an error on ambiguous columns and the LCA could/must be addressed with a default identifier.Thanks
When trying to execute a query via sql warehouse, I get the following error:INVALID_PARAMETER_MARKER_VALUE.DUPLICATE_NAMEthe sql statement uses ? placeholders and the correct number of arguments are being passed.I am not able to use named placeholder...
Hi @RickB ,Which API are you using to invoke this? Parameter markers can be provided by:Python using its pyspark.sql.SparkSession.sql() API.Scala using its org.apache.spark.sql.SparkSession.sql() API.Java using its org.apache.spark.sql.SparkSession.s...
I'm planning to connect SQL Server Management Studio (SSMS) with Databricks using Lakehouse Federation. I understand that there are some differences in the SQL dialects between SSMS and Databricks SQL. For instance, in SSMS, we use TOP 10 to limit th...
To add on this:if you really have to use T-SQL (the MS dialect of SQL), you can define the SQL warehouse from databricks as a linked server on your SQL server.As said: SSMS is merely a sql client, the SQL dialect to be used is defined by the database...
