Learn about SOQL and SOSL, which are similar to SQL or MySQL, but have governor limits you need to be aware of when writing queries.
- [Instructor] SQL-Like but Different.…SOQL, which is Salesforce's Object Query Language,…is very similar to SQL.…Though you will find, if you are an expert SQL developer,…that you're going to run into challenges…trying to create some of those queries in SOQL.…SOQL is very specific.…It has been optimized…to work for Salesforce…and its underlying database.…Salesforce does provide a deeper look into that…and we're going to take a quick look at that now.…
On this page here, Salesforce goes into…a complete discussion of why SOQL is different…and how it actually relates…to various aspects of the force.com platform.…So you'll want to go through this deep dive here…and you want to understand the differences…between what SOQL provides and why…in order to query the various objects…that Salesforce provides in the Salesforce platform.…Keeping in mind that it's similar but it is different,…what I personally recommend is that you start…with a very simple, small query.…
Make sure that is doing what you want it to do.…And then you can start to add complexity.…
