OpenSQL is one of the most important parts of the daily work of an ABAP programmer. To do it right, practice is necessary, and so I encourage you to do this in order to improve your understanding of SQL.
In this chapter, we discussed the basics of ABAP OpenSQL and the advanced functions of SQL. You were also shown how to change data in databases, how to optimize big datasets, and how to measure the efficiency of SQL statements and tracing database operations.
In the next chapter, this knowledge will prove really useful. We will look at how to import and export a documents format, which will be important in scenarios such as ensuring that mass importing or exporting will be executed with efficiency.
