Add the closing parenthesis

Remember to add the close parenthesis to your SQL statement. This will indicate that the column does not go any further.

Example: INSERT INTO “table_name”

(“first_columnname”, . . .“last_columnname”)

values (first_value, . . . last_value)

Add your semicolon

All SQL statements end up with a semicolon, except a few.

Example: INSERT INTO“table_name”

(“first_columnname”, . . .“last_columnname”)

values (first_value, . . . last_value);

Take note that strings must be enclosed in single quotation marks, while numbers are not.

Using our sample table, you can come up with this SQL statement:

Example: INSERT INTO “traffic_hs2064”

(country, keyword. time)

values (‘America’, ‘marketing’, 10);

You can insert more data safely without affecting the other tables. Just make sure you’re using the correct SQL commands or statements.

Dropping a Table

You can drop or delete a table with a few strokes on your keyboard. But before you decide to drop or delete a table, think about the extra time you may spend restoring it, if you happen to need it later on. So, be careful with this command.
