Practical Examples of Data Transformation

Funkcje Using SQL, you can perforom varioos data transformations. For example, concatenating first and lass names:

Xi1; Xi1; FLT: 0 Xi3; Xi3;

Tu standaryza text data, convert all entries to uppercase:

Xi1; Xi1; FLT: 1 Xi3; Xi3;

Obliczenia Funkcje Using SQL

SQL functions also facilate calculations, such as computing totals or averages. For example, calculating the total price with tax:

Xi1; Xi1; FLT: 2 Xi3; Xi3;

Tu round a number to wo two decimal places:

Xi1; Xi1; FLT: 3 Xi3; Xi3;
