As per the Salesforce Documentation, Dynamic Apex enables developers to create more flexible applications. In other words, we can say that using dynamic apex, you can write Generic Code that can be re-used again and again with multiple sObjects. So, the logic that you’ve written is not object dependent.

What is the static and dynamic apex in Salesforce?
Static SOQL is one which you write in square brackets. It is good to use when you didn’t have any dynamic changes in the soql query. Dynamic SOQL refers to the creation of a SOQL string at runtime with Apex code.
What does dynamic mean in Salesforce?
What are Salesforce Dynamic Forms? The premise of Dynamic Forms is to create user centric, intuitive page layouts that display the right information at the right time. Over time, the page layout, or “Details” section in Lightning pages, can become congested with fields.
What is Salesforce Apex used for?
Apex enables developers to access the Salesforce platform back-end database and client-server interfaces to create third-party SaaS applications. Apex includes an application programming interface (API) that Salesforce developers can use to access user data on the platform.
What is dynamic SOSL in Salesforce?
Dynamic SOSL refers to the creation of a SOSL string at run time with Apex code. Dynamic SOSL enables you to create more flexible applications. For example, you can create a search based on input from an end user, or update records with varying field names.
What are some of the advantages of dynamic apex?
Dynamic Apex enables developers to create more flexible applications by providing them with the ability to “Access sObject and field describe information”, “Write Dynamic SOQL Queries”, “Write Dynamic SOSL Queries” and “Dynamic DML”.
What is difference between static and dynamic dashboards?
A Static Dashboard is the default in Salesforce. Dynamic Dashboards can be customized to each viewers needs regardless of what they have permission to see in Salesforce.

What is Apex and Visualforce?
Apex and Visual Force. Visualforce is a component-based user interface (UI) framework that allows the development of strong and reusable interfaces. Apex is a platform for developing software as a service (SaaS) applications based on the CRM functionality of Salesforce.
What is batch Apex in Salesforce?
Batch Apex is used to run large jobs (think thousands or millions of records!) that would exceed normal processing limits. Using Batch Apex, you can process records asynchronously in batches (hence the name, “Batch Apex”) to stay within platform limits.
What is difference between SOQL and SOSL?
SOSL & SOQL. The chart below describes the differences….Difference between SOSL and SOQL search types.SOQLSOSLSearch Focus:Accuracy. Gives full set of results that match criteria.Relevance & Speed.

What is the difference between SOQL and SOSL query in Salesforce?
Unlike SOQL, which can only query one object at a time, SOSL enables you to search text, email, and phone fields for multiple objects simultaneously. You use SOSL with the search() call in the API and SOQL with the query() call.
What is dynamic SOQL in Salesforce?
Dynamic SOQL refers to the creation of a SOQL string at run time with Apex code. Dynamic SOQL enables you to create more flexible applications. For example, you can create a search based on input from an end user or update records with varying field names. To create a dynamic SOQL query at run time, use the Database.

We can also use schemaDescribe () to create tree structure of all the objects and fields in the schema browser, to do this we need to use the codemap

What is Dynamic Apex?
In other words, we can say that using dynamic apex, you can write Generic Code that can be re-used again and again with multiple sObjects. So, the logic that you’ve written is not object dependent. You can make your SOQL queries, SOSL queries and DML statements dynamic. Let’s have a look at some good use cases to see how that works.
Can you use Dynamic Apex to create SOSL?
You can also use Dynamic Apex to create SOSL. The procedure is same like we did for SOQL. Have a look at the below screenshots from sObject Convertor where we used SOSL to find the records based on the source object selected in the component and the search text entered by the user.

Dynamic SOQL Considerations
You can use simple bind variables in dynamic SOQL query strings. The following is allowed:
SOQL Injection
SOQL injection is a technique by which a user causes your application to execute database methods you did not intend by passing SOQL statements into your code. This can occur in Apex code whenever your application relies on end user input to construct a dynamic SOQL statement and you do not handle the input properly.
Dynamic sObject Creation Example
This example shows how to obtain the sObject token through the Schema.getGlobalDescribe method and then creates a new sObject using the newSObject method on the token. This example also contains a test method that verifies the dynamic creation of an account.
Setting and Retrieving Field Values
Use the get and put methods on an object to set or retrieve values for fields using either the API name of the field expressed as a String, or the field’s token. In the following example, the API name of the field AccountNumber is used:
Setting and Retrieving Foreign Keys
Apex supports populating foreign keys by name (or external ID) in the same way as the API. To set or retrieve the scalar ID value of a foreign key, use the get or put methods.
