Metabase Mongodb Query

If you are using a Metabase version earlier than 0.33, you will need to either write a SQL query that contains joins, or have your Metabase administrator set up foreign keys (they can read more about that here). If you are using Metabase 0.33 or above, you can perform joins using the Notebook editor. See something that needs fixing? Precog allows any user to ingest new data sources directly into Metabase, regardless of source, size, or complexity. Metabase users can access API’s, NoSQL DB’s, Applications, or any data source they choose. Precog lets the user pick the exact data they need for any new tables they want to add to Metabase. If you are using a Metabase version earlier than 0.33, you will need to either write a SQL query that contains joins, or have your Metabase administrator set up foreign keys (they can read more about that here). If you are using Metabase 0.33 or above, you can perform joins using the Notebook editor.

Pivot tables are a tabular way to summarize and group data. They’re a valuable tool in the analyst’s toolkit, as they’re an efficient way to present — and rearrange — a lot of information. Here’s how they work:

Pivot tables vs. regular tables

Your typical, basic table is a grid of cells. Each column represents an attribute of a single record, with a single record per row.

A pivot table is a table that groups rows and columns, and includes summarial rows with aggregate values for those groupings. These aggregate values are usually referred to as subtotals and grand totals, though these aggregates could also be other values, such as averages.

The reason they’re called pivot tables is because you can rotate (“pivot”) a column 90 degrees so that the values in that column become column headings themselves. Pivoting values into column headings can be really helpful when trying to analyze data across multiple attributes, like time, location, and category. You can pivot multiple columns, or not pivot any at all.

This is all pretty abstract, so let’s walk you through an example to give you a feel for how pivot tables work.

Pivoting tables

To start, let’s say we want to know:

how much annual revenue orders are bringing in
for each state (i.e., where do our customers live?)
and how those orders break down by product category

Here’s our query using the notebook editor:

Here we’re taking data from the Orders table and summarizing the records. We’re grouping the orders by User -> State, Created At (by year), and Product -> Category. For each group (say Alaska in 2017), we count the number of orders and add up the subtotals for those orders. (Note that, even though we’ve only selected the Orders table in the data section, Metabase will automatically join the Products and People tables to get the State and Category data.)

The resulting table is a regular one, with rows for each combination of state, year, and product category.

Now, let’s say that for each state, we also want to know the sum of the annual subtotals for each state (e.g., how much money did orders for Doohickey products make in Alaska for all years?). To find out, we could add up the subtotals ourselves, or use a pivot table to calculate that figure for us. At the bottom left of your screen, select Visualization then click on the Pivot Table option.

In our pivot table, Metabase has set the rows, columns, and values as follows:

rows: User -> State and Created At (by year)
columns: Product -> Category
values: Count and Sum of Subtotal

Like the flat table, the pivot table lets us see, for example, that in 2020 our customers in Alaska (AK) have purchased a combined 11 Doohickey products for $867.63. But now the pivot table has grouped the rows related to Alaska, and given a subtotal for those Alaskan rows, allowing us to see the answer to our question: Alaskans purchased 103 Doohickeys from 2016–2020, totaling $6,900.43.

In addition to the group subtotals, the pivot table also includes both row and column grand totals:

Row grand total example: the total number of Doohickey orders placed across all states.
Column grand total example: the sum of all subtotals in Alaska across all product categories.

We can navigate the table by collapsing and expanding groups of rows:

Now, let’s try “pivoting” the table. In the bottom left of the screen, we’ll click on Settings, which brings up Pivot Table options. To pivot the table, we’ll move fields between the three buckets: rows, columns, and values.

Order within a single bucket matters, so let’s start by simply rearranging the table within a single bucket: the rows bucket. If we switch the order of fields to use for table rows, putting Created At above User -> State, the table will rearrange itself:

Now the table groups first by year, then gives a breakdown of orders for each state across each product category.

We can also switch fields between the buckets, like moving Product -> Category from a column to a row, and User -> State from a row to a column.

You can also turn off subtotals for a given row grouping:

Like with flat tables, we have some sorting and formatting options, and we can click on values in the table to bring up the Action menu, which will lets us drill through the data.

Pivot tables only work with databases that support joins and expressions, so you won’t be able to use them with databases like MongoDB and Google Analytics. They also only work with questions composed with the GUI editors (i.e., simple and custom questions). The workaround here is that if you must use SQL to compose a question, you can save that question, then use its results as the starting point for a GUI question in order to build a question. The trick here is to do your aggregation and grouping in the GUI question. That is, use the SQL question to grab the raw data you want to work with, then start a new GUI question to filter, summarize, and group that data.

For example, to use a SQL question to build the pivot table we created above, you’d first write a SQL query to get the raw data you want to work with:

Notice that we’re just grabbing records here; there’s no summarizing or grouping. Next, we save that SQL question (here as “Raw data for pivot table”), and start a new simple or custom question that uses the results of that question as its starting data.

Now we can count, sum, and group our results:

When we visualize this question, we’ll now be able to use the pivot table visualization to see the group subtotals and grand totals.

MongoDB C# find by date

MongoDB - search by date and time using C# driver, Add BSON attribute on dateTime field (see below),. you can use linqu syntax to build such a query var min = new DateTime(2016, 03, 03, 22, 0, 0); var max Getting this in C# returns a date which is actually a UTC date (the Kind property is UTC), which btw is indicated by the 'Z' suffix of the value in db. Comparing this UTC date with a new DateTime() makes not much sense, as the latter creates a date in your time zone, which can be different than +0 (UTC).

MongoDB match between dates

MongoDB Database Big Data Analytics Use operator g t e a n d lt to find objects between two dates in MongoDB. To understand these operators, let us create a collection. Creating a collection here:

MongoDB actually stores the millis of a date as an int (64), as prescribed by http://bsonspec.org/#/specification However, it can get pretty confusing when you retrieve dates as the client driver will instantiate a date object with its own local timezone. The JavaScript driver in the mongo console will certainly do this.

To match, use $ match in MongoDB and to get data between two dates, use $ gte and $ lte. Let us create a collection with documents −. > db.demo560.insertOne( {'value1':40,'value2':40,shippingDate:new ISODate('2020-02-26')}); { 'acknowledged' : true, 'insertedId' : ObjectId('5e8f3d5254b4472ed3e8e867') } > db.demo560.insertOne( {'value1':20,'value2':60,shippingDate:new ISODate('2020-02-26')}); { 'acknowledged' : true, 'insertedId' : ObjectId('5e8f3d5254b4472ed3e8e868') } > db.demo560

MongoDB date operations

Date(), These functions accept the following formats: new Date('<YYYY-mm-dd>') returns the ISODate with the Date () ¶ Date () returns the current date as a string in the mongo shell. new Date () returns the current date as a Date object. The mongo shell wraps the Date object with the ISODate helper. new Date ('<YYYY-mm-dd>') returns the ISODate with the specified date. new Date ('<YYYY-mm-ddTHH:MM:ss>')

$toDate (aggregation), The following aggregation operation on the orders collection converts the order_date to date before sorting by the date value: copy. copied. // Define stage to Behavior¶. When using an Olson Timezone Identifier in the <timezone> field, MongoDB applies the DST offset if applicable for the specified timezone.. For example, consider a sales collection with the following document:

$subtract (aggregation), db.sales.aggregate( [ { $project: { item: 1, dateDifference: { $subtract: [ new Date(), '$date' ] } } } ] ). Both operations return documents that resemble the following:. If the two values are dates, return the difference in milliseconds. If the two values are a date and a number in milliseconds, return the resulting date. Accepts two argument expressions. If the two values are a date and a number, specify the date argument first as it is not meaningful to subtract a date from a number.

MongoDB date query

Date(), The mongo shell wraps the Date object with the ISODate helper. The ISODate is in UTC. You can specify a particular date by passing an ISO-8601 date string with a year within the inclusive range 0 through 9999 to the Use Date in a Query¶. MongoDB stores datetime as UTC (To confirm this edit Mongo document and you will see Z at the end in ISODate( …. ) value). When you use ZappySys MongoDB SQL Query Syntax like below it may or many not perform Automatic Date Conversion from Local to UTC. If you suffix “Z” after date/time value then its treated as UTC and no DateTime conversion happens.
