Querying with OCNQL

On this page

The Open Connectors Query Language (OCNQL) provides a standard way to search across all of our connectors. Many API providers support some form of searching in their APIs but each one approaches searching differently. Rather than having you research how to query each resource at a provider, we've normalized your search experience. SAP Open Connectors translates your queries to the API provider's search syntax.

OCNQL Overview

OCNQL represent the "where" portion of a typical query that can include many other components like field selection, sorting, and pagination. Take a look at GET requests or POST /bulk/query in the API docs for any connector to see how you can structure your queries. Here are some examples from QuickBooks Online, MailChimp, and Salesforce Sales Cloud. OCNQL in API Docs

The easiest way to make queries is through the API docs, but when you integrate your code with SAP Open Connectors you'll need to understand how to structure queries with OCNQL.

You compose queries with available query connectors field selection, sorting, and pagination. Each connector allows different components of the query, but in most situations you can use some common parts. The most common components include the object name, OCNQL expression, field selection, field sorting, and pagination. Here's how you might construct a query:

<object name>?where <expression>&<select fields>&<sort fields>&<page size (limit)>&<page offset (offset)>

An example query with all components:

/contacts?where=Department!='Procurement'&fields=username&orderBy=MailingCity asc&page=1&pageSize=10

Query Reference

Query ComponentExampleDescription
Object name/contacts?where=Department!='Procurement'&fields=username&orderBy=MailingCity asc&page=1&pageSize=10The name of the object to search.
OCNQL query
the "where" expression
/contacts?where=Department!='Procurement'&fields=username&orderBy=MailingCity asc&page=1&pageSize=10The expression or expressions specifying what to search and what objects to return in our result set. See Valid OCNQL Operators.
This is made up of a left­ hand ­side (LHS), an operator and a right­ hand­ side (RHS).
Select fields/contacts?where=Department!='Procurement'&fields=username&orderBy=MailingCity asc&page=1&pageSize=10The field or fields to return in your result set.
Field selection is available only for connectors where the resource supports selecting fields. When not available, you can use a common resource to filter the fields that you receive in a response.
Sort fields/contacts?where=Department!='Procurement'&fields=username&orderBy=MailingCity asc&page=1&pageSize=10The field or fields to sort your result set.
Include asc to sort ascending, and desc for descending.
Pagination/contacts?where=Department!='Procurement'&fields=username&orderBy=MailingCity asc&page=1&pageSize=10page is the offset to begin your results.
pageSize is the maximum number of results to return.

Examples

Equal Operator

Select from accounts where the Name equals a specific value. Select where name

OR and Greater Than Operators

Select from accounts where the name equals a specific value OR the Industry is a specific value AND the LastModifiedDate > a specific value. Select where name and name and date

When working with dates and time, wrapping a value in the ` character will ensure a column does not get split.

For example: select * from customers ‘metaData.lastUpdateTime> 2015-01-06T09:31:38-07:00’

Since the `metaData.lastUpdateTime > 2015-01-06T09:31:38-07:00′is wrapped in \ character, the column will not get split.
