Check the Schema:
Table structure in most database clients, such as MySQL Workbench, pgAdmin, SQL Server Management Studio, or Oracle SQL Developer contains icons indicating the primary key column or is labeled as such.
Examine Table Design:
Right click the table in your database GUI and then open it in design or structure view. The names of the primary key column(s) will be underlined or asterisked.
Review Documentation:
If you don’t operate within a GUI, you can check the table structure documentation or, in the worst case, figure out what the primary key is, as it is described in the table definition.
