LINQ syntax differences: Devo APIs vs search window

[ 1 Addition, sum, plus / Concatenation (add, +) operations ] [ 2 Maximum (max) operations → create field ] [ 3 Minimum (min) operations → create field ] [ 4 Mlevalmodel operation ] [ 5 Multiplication, product (mul, *) operations ]

Due to architectural differences, the LINQ syntax presents some particularities in the Devo APIs and the search window of the Devo app.

Therefore, keep in mind that copying a LINQ query from the search window and pasting it into an API request, or vice versa, might not work. Before examining the differences explained below, you can visit Build a query using LINQ to know the standard procedures when working with LINQ.

Alerts API

Note that due to technical reasons, the Alerts API is the only API that uses the LINQ syntax used in the search window of the Devo app. This is indicated in the different sections below.

Addition, sum, plus / Concatenation (add, +) operations

When you use this operation in the Data Search, you can add as many arguments as needed (where applicable), however, the number of arguments is limited to two when used in APIs.

As a workaround, you can perform subsequent adding operations until you have added all the arguments you need.

Other Devo APIs

Syntax:

Create field: select add(value1, value2, value3, value4...) as totalField

Query example:

from demo.ecommerce.data
select add(bytesTransferred, timeTaken, statusCode) as `totalField`

Syntax:

Create field: select add(value1, value2) as totalFieldA, add(totalFieldA, value3) as totalFieldB, add(totalFieldB, value4) as totalFieldC...

Query example:

from demo.ecommerce.data
select add(bytesTransferred, timeTaken) as totalFieldA, add(totalFieldA, statusCode) as totalFieldFinal

Maximum (max) operations → create field

When you use this operation in the Data Search to create a new field, you can add as many arguments as needed, however, the number of arguments is limited to two when used in APIs.

As a workaround, you can perform subsequent maximum operations until you have obtained the maximum of all the arguments you need.

Syntax:

Create field: select max(value1, value2, value3, value4...) as maxField

Query example:

from demo.ecommerce.data
select max(bytesTransferred, timeTaken, statusCode) as `maxField`

Syntax:

Create field: select max(value1, value2) as maxFieldA, max(maxFieldA, value3) as maxFieldB, max(maxFieldB, value4) as maxFieldC...

Minimum (min) operations → create field

When you use this operation in the Data Search to create a new field, you can add as many arguments as needed, however, the number of arguments is limited to two when used in APIs.

As a workaround, you can perform subsequent minimum operations until you have obtained the minimum of all the arguments you need.

Syntax:

Create field: select min(value1, value2, value3, value4...) as minField

Query example:

Syntax:

Create field: select min(value1, value2) as minFieldA, min(minFieldA, value3) as minFieldB, min(minFieldB, value4) as minFieldC...

Query example:

Mlevalmodel operation

mlevalmodel operation is not supported in search window. Use this operation in APIs when you want to work with models you uploaded in Model Management.

Multiplication, product (mul, *) operations

When you use this operation in the Data Search, you can add as many arguments as needed, however, the number of arguments is limited to two when used in APIs.

As a workaround, you can perform subsequent multiplication operations until you have multiplied all the arguments you need.
