Some people are quick learners and can absorb new information after a few days of practicing. Others may take more time, practice, and researching to comprehend and get and true understanding of SQL commands are fundamental concepts. Other factors such as patience when receiving an SQL error or the dedication to starting a SQL project and asking questions when confronted with a SQL error. These factors can go a long way in decreasing the learning curve. But overall, it will typically take you about a few weeks or months of intentional, directed effort towards learning SQL and then you can start looking for SQL jobs and entry- level SQL developer jobs.
