exists( )


Refines a query to match items where the specified property contains a value.

The exists() function refines a DiscountRulesQueryBuilder to only match items where the value of the specified propertyName doesn't equal null or undefined. exists() checks for either existence or non-existence based on the boolen parameter. Note that exists() does match items where the value of the specified propertyName is an empty string or an invalid value. exists() is only useful for properties which don't contain default values and therefore their values may be unassigned.

Method Declaration

function exists(
  propertyName: string,
  value: boolean,
): DiscountRulesQueryBuilder;

The find() function returns a Promise that resolves to the query results and metadata. The Promise is rejected if find() is called with insufficient permissions or if any of the previous functions used to refine the query are invalid.

Method Declaration
Copy
function find(): Promise<DiscountRulesQueryResult>;
Request
This method does not take any parameters
Returns
Return Type:Promise<DiscountRulesQueryResult>
JavaScript
const query = discountRules.queryDiscountRules.find();

ge( )


Refines a query to match items where the specified property is greater than or equal to the specified value.

The ge() function refines a DiscountRulesQueryBuilder to match only items where the value of the specified propertyName is greater than or equal to the specified value. ge() matches only values of the same type. For example, 0 stored as a number doesn't match '0' stored as a string. If a property contains a number stored as a string (for example, '0'), that value is compared alphabetically and not numerically. If a property doesn't have a value, that value is ranked lowest. The following types of properties can be compared:

  • Number: Compares numerically.
  • Date: Compares JavaScript Date objects.
  • String: Compares lexicographically, so 'abc' is greater than 'ABC'.
Method Declaration
Copy
function ge(propertyName: string, value: any): DiscountRulesQueryBuilder;
Method Parameters
propertyNamestring

Property whose value is compared with value.


valueany

Value to compare against.

Returns
JavaScript
const query = discountRules.queryDiscountRules.ge("_createdDate", "2021-03-01");

gt( )


Refines a query to match items where the specified property is greater than the specified value.

The gt() function refines a DiscountRulesQueryBuilder to match only items where the value of the specified propertyName is greater than the specified value. gt() matches only values of the same type. For example, 0 stored as a number doesn't match '0' stored as a string. If a property contains a number stored as a string (for example, '0'), that value is compared alphabetically and not numerically. If a property doesn't have a value, that value is ranked lowest. The following types of properties can be compared:
