SFRestAPI (QueryBuilder) Category
If you’re unsure of the correct syntax for a SOQL query or a SOSL search, you can get help from the SFRestAPI (QueryBuilder)
category methods. These methods build query strings from basic conditions that you specify, and return the formatted string. You can pass the returned string to SFRestAPI
or RestClient
request methods for query or search.
SFRestAPI (QueryBuilder)
provides two static methods each for SOQL queries and SOSL searches: one takes minimal parameters, while the other accepts a full list of options. Swift versions of these methods are not defined explicitly by Mobile SDK. To code these methods in Swift, use the autocomplete suggestions offered by the Xcode compiler. These suggested method and parameter names are determined by Swift compiler heuristics and can differ from their Objective-C equivalents.
SOSL query builder methods are:
- Swift (Compiler-generated)
- Objective-C
Parameters for the SOSL search methods are:
-
Swift Objective-C withSearchTerm
term
-
The search string. This string can be any arbitrary value. The method escapes any SOSL reserved characters before processing the search.
Swift Objective-C fieldScope
fieldScope
-
Indicates which fields to search. It’s either
nil
or one of the IN search group expressions: “IN ALL FIELDS”, “IN EMAIL FIELDS”, “IN NAME FIELDS”, “IN PHONE FIELDS”, or “IN SIDEBAR FIELDS”. Anil
value defaults to “IN NAME FIELDS”. See Salesforce Object Search Language (SOSL).Swift Objective-C objectScope
objectScope
-
Specifies the objects to search. Acceptable values are:
-
nil
—No scope restrictions. Searches all searchable objects. -
An
NSDictionary
object pointer—Corresponds to the SOSL RETURNING fieldspec. Each key is ansObject
name; each value is a string that contains a field list as well as optional WHERE, ORDER BY, and LIMIT clauses for the key object.If you use an
NSDictionary
object, each value must contain at least a field list. For example, to represent the following SOSL statement in a dictionary entry:set the key to “Widget__c” and its value to “name WHERE
createddate
= “THIS_FISCAL_QUARTER”. For example: -
NSNull
—No scope specified.
Swift Objective-C limit
limit
-
-
To limit the number of results returned, set this parameter to the maximum number of results you want to receive.
SOQL QueryBuilder methods that construct SOQL strings are:
- Swift (Compiler-generated)
- Objective-C
Parameters for the SOQL methods correspond to SOQL query syntax. All parameters except withFields
/fields
and sObject
can be set to nil
.
-
Swift Objective-C withFields
fields
-
An array of field names to be queried.
Swift Objective-C sObject
sObject
-
Name of the object to query.
Swift Objective-C whereClause
where
-
An expression specifying one or more query conditions.
Swift Objective-C groupBy
groupBy
-
An array of field names to use for grouping the resulting records.
Swift Objective-C having
having
-
An expression, usually using an aggregate function, for filtering the grouped results. Used only with
groupBy
.Swift Objective-C orderBy
orderBy
-
An array of fields name to use for ordering the resulting records.
Swift Objective-C limit
limit
-
Maximum number of records you want returned.
See SOQL SELECT Syntax.
The QueryBuilder
category also provides a class method for cleaning SOSL search terms:
- Swift
- Objective-C
This method escapes every SOSL reserved character in the input string, and returns the escaped version. For example:
- Swift
- Objective-C
This call returns “FIND \{MyProspect\}”.
The sanitizeSOSLSearchTerm
method is called in the implementation of the SOSL and SOQL QueryBuilder methods, so you don’t need to call it on strings that you’re passing to those methods. However, you can use it if, for instance, you’re building your own queries manually. SOSL reserved characters include:
\ ? & | ! { } [ ] ( ) ^ ~ * : " ' + -
