SQL basics
TableA named set of data, like customers or transactions.
RowOne record inside a table.
ColumnOne detail in each row, like amount or country.
SELECTThe columns you want to see.
FROMThe table you want to use.
WHEREThe rule for which rows to keep.
What running SQL looks like
SELECT name, risk_level FROM customers;
| name | risk_level |
|---|---|
| Avery Stone | medium |
| Blair Kim | high |
| Casey Rivera | high |
The SQL on the left asks for two columns. The result on the right is what comes back from the customers table.
