apex-soqlbuilder's Introduction

Apex SOQLBuilder

Salesforce Apex Class for dynamic query builder and DML operations. You can construct query more intuitively because those methods arranged here are able to be used with conditional branching, loop handling and others.

Introduction

Development of Apex class needs to describe Salesforce's unique language called SOQL to handle DML operations for sObjects. More conditions to filter sObject records to get, query becomes longer and more redundant, which makes it difficult to describe dynamic query.
On this occasion, SOQLBuilder class has been defiened to solve this problem. The concept of MVC framework is consulted for this class that incorporates a part of features of Model. The goal is to realize the way of SOQL query description with more simplisity, readability, variability and availability.

Sample of usage

Sample 0

SOQLBuilder bld = new SOQLBuilder(); // Create the class instance

Sample 1

bld.soqlSelect('Id');
bld.soqlSelect('Name');
bld.soqlSelect('Alias');
List<User> user = bld.soqlGet('User');

Or in another way,

bld.soqlSelect('Id, Name, Alias');
List<User> user = bld.soqlGet('User');

The method call like above is exactly the same thing as following.

List<User> user = [
    SELECT
        Id,
        Name,
        Alias
    FROM
        User
];

Sample 2

bld.soqlSelect('*');
bld.soqlWhere('Id', '00s4h00000216cCDXW');
List<Account> accList = bld.soqlGet('Account');

Or in another way,

bld.soqlWhere('Id', '00s4h00000216cCDXW');
List<Account> accList = bld.soqlGet('Account');

The method call like above is exactly the same thing as following.

List<Account> accList = [
    SELECT
        Id,
        Name,
        AccountNumber,
        AccountSource,
        AnnualRevenue,

        LastReferencedDate,
        LastViewedDate,
        MasterRecordId,
        NaicsCode,

        OwnerId,
        Ownership,
        ParentId,
        PersonIndividualId,
        Phone,
        ...., // abbr.
        LastModifiedDate,
        CreatedById
    FROM
        Account
    WHERE
        Id = '00s4h00000216cCDXW'
];

Sample 3

bld.soqlSelect('Id, Name');

for (Integer i = 0; i < 100; i++) {
    bld.soqlOrWhere('Name', 'Misaka' + i);
}

List<Account> accList = bld.soqlGet('Account');

The method call like above is exactly the same thing as following.

List<Account> accList = [
    SELECT
        Id,
        Name
    FROM
        Account
    WHERE
        Name = 'Misaka0' OR Id = 'Misaka1' OR Id = 'Misaka2' OR Id = 'Misaka3' ...  OR Id = 'Misaka99'
];

Sample 4

SOQLBuilder bld = new SOQLBuilder();
RestRequest req = RestContext.request;

// Get URL Query Parameters
Integer limitVal  = (Integer)req.params.get('limit');
Integer offsetVal = (Integer)req.params.get('offset');

// Construct SOQL Query
bld.soqlSelect('Id, Name, Phone');

// Only when parameters are set
if (limitVal != null) { // When Not null
    bld.soqlLimit(limitVal);
}
if (offsetVal != null) { // When Not null
    bld.soqlOffset(offsetVal);
}

// Execute Query
List<Account> accList = bld.soqlGet('Account');

The method call like above is exactly the same thing as following.

SOQLBuilder bld = new SOQLBuilder();
RestRequest req = RestContext.request;

// Get URL Query Parameters
Integer limitVal  = (Integer)req.params.get('limit');
Integer offsetVal = (Integer)req.params.get('offset');

// Have to describe SOQL queries for all patters of conditions
List<Account> accList = new List<Account>();
if (limitVal != null && offsetVal != null) {
    accList = [SELECT Id, Name, Phone FROM Account LIMIT :limitVal OFFSET :offsetVal];
} else if (limitVal != null && offsetVal == null) {
    accList = [SELECT Id, Name, Phone FROM Account LIMIT :limitVal];
} else if (limitVal == null && offsetVal != null) {
    accList = [SELECT Id, Name, Phone FROM Account OFFSET :offsetVal];
} else {
    accList = [SELECT Id, Name, Phone FROM Account];
}

Sample 5

SOQLBuilder bld = new SOQLBuilder();

RestRequest req = RestContext.request; // Rest API Context

// Get API request body, key: sObject field name / value: sObject field value
Map<String, Object> params = (Map<String, Object>)JSON.deserializeUntyped(req.requestBody.ToString());

// Some verifying process (abbr.)
***

// Get Name
String accName = (String)params.get('Name');

// Get sObject record of the Name
bld.soqlSelect('Id');
bld.soqlWhere('Name', accName);
List<Account> accList = bld.soqlGet('Account');

// DML Operation
Map<String, Object> result = bld.soqlUpdate(accList, params); // Just simply assign "params" variable

// Verify result
if (! (Boolean)result.get('success') ) { // When failed
    Exceptiopn e = (Exceptiopn)result.get('error');
    System.debug(e.getMessage());
    return;
}

はじめに

Apex での sObject の DML 操作は SOQL と呼ばれる Salesforce 独自の言語が必要となり、開発において都度クエリを記述する必要がある。クエリの絞り込みが多くなるにつれてコードは冗長化し、動的なクエリの記述は難しくなる。
この課題を解決する目的として、SOQLBuilder クラスを定義することにした。このクラスは、フレームワークの概念である MVC を参考にして、「モデル」機能の一部の動作を模倣するものである。これにより、SOQL クエリを直書きするよりも簡略的で可読性、可変性、可用性の高い記法の実現を目指している。
