The app expression is used in an Azure Monitor query to retrieve data from a specific Application Insights app in the same resource group, another resource group, or another subscription. This is useful to include application data in an Azure Monitor log query and to query data across multiple applications in an Application Insights query.Here are 3 methods to do the INSERT INTO #temp. Method 1 requires both tables to have the exact same column names and count. The other 2 methods require you to define the columns you want inserted since we aren't using SELECT * anymore. email_address nvarchar(50) email_address nvarchar(50) SELECT. email_address.1. The query below is giving this error: 'extend' operator: Failed to resolve scalar expression named 'traces'. The idea is to do a count of all log messages that start with 'message prefix' that appear between 'start message' and 'end message'. Here is the query: | where message == 'start message'. | project event = 'START', message, timestamp.I have 2 KQL queries and I want to combine them in order to display two rows as one result. Not just result of first query, then result of second query:Resource Graph supports a subset of KQL data types, scalar functions, scalar operators, and aggregation functions. Specific tabular operators are supported by Resource Graph, some of which have different behaviors. Supported tabular/top level operators. Here's the list of KQL tabular operators supported by Resource Graph with specific samples:

I want to output multiple lists of unique column values with KQL. For instance for the following table: A B C 1 x one 1 x two 1 y one I want to output K V A [1] B [x,y] C [one, two] IExamples. The partition operator partitions the records of its input table into multiple subtables according to values in a key column. The operator runs a subquery on each subtable, and produces a single output table that is the union of the results of all subqueries. This operator is useful when you need to perform a subquery only on a …

The materialize() function is useful to cache query results that will be used in subsequent query statements, for example, if you have a summarization by an organization and then a column that displays it as percentage of the total, in such case materializing the results of the aggregation and then calculating the total, will reduce significantly …

Garnishing with graphs and data charts. There are dozens of functions and techniques with KQL for producing big data charts and graphs. Here's an example of a function that decomposes time series data and outputs it in a series of line charts: let min_t = datetime(2025-01-05); let max_t = datetime(2025-02-03 22:00); let dt = 2h;You should look into arg_min and arg_max which directly answers your original question about getting the value of a different column than the one being maximized (or minimized). Copying the example from the docs: StormEvents. | summarize arg_max(BeginLat, BeginLocation) by State. This gives you the BeginLocation of the maxium BeginLat by State ...Creating a cross-workspace rule is very easy…the only thing that changes compared to a regular rule is the query itself. In order to span multiple workspaces, you need to include the workspace and union KQL statements, adding tables from other workspaces as needed (remember the limit is 10). For example, a query to find EventID 4625 in two ...string. ️. A downstream pipeline of supported query operators. name. string. A temporary name for the subquery result table. Note. Avoid using fork with a single subquery. The name of the results tab will be the same name as provided with the name parameter or the as operator.

In this episode of Data Exposed: MVP Edition with Anna Hoffman, Hamish Watson will introduce you to the Kusto Query Language (KQL) which will allow you to query a variety of Azure resources. The session will also show how machine learning and time-series analytics can help advance your insights into your Azure services. Watch on Data Exposed

Another round of union happens on the aggregated nodes data. A final aggregation happens on top level. Basic KQL operators. Now that we have seen how a query is structured and optimized by Azure Synapse Data Explorer Engine, we can start writing some basic KQL. Most of the KQL queries can be fulfilled by certain common operators listed below:

In short, no. Unioning result sets together must have the same number / data type of columns. If you wanted to have the remaining sets populate null, the simplest way to do this would be to do something like so-select col1 , col2 , col3 , col4 from tbl1 union all select null as col1 , null as col2 , null as col3 , null as col4 from tbl2%kql --conn To check the details of a specific connection, run the following command: %kql --conn <database-name>@<cluster-name> Query and visualize.

1. if the input is of type string, you first need to invoke parse_json() on it, to make it of type dynamic.

In relational algebra (which SQL isn't) the union result might be one row, though only if the two input relations contained an identical tuple, eg. self-union of a one-tuple relation. – Robert Monfera.

A view is a virtual table based on the result-set of a Kusto Query Language (KQL) query. Like real tables, views organize data with rows and columns, and participate in tasks that involve wildcard table name resolution, such as union * and search * scenarios. However, unlike real tables, views don't maintain dedicated data storage.In order of importance: Only reference tables whose data is needed by the query. For example, when using the union operator with wildcard table references, it is better from a performance point-of-view to only reference a handful of tables, instead of using a wildcard (*) to reference all tables and then filter data out using a predicate on the source table name.
