Update Queries

For updating values already entered into a database. Can edit multiple rows at once. Not using the WHERE clause will cause every entry to be edited.

Editing 'table':

Indented line

"UPDATE table SET column1=value1 WHERE column2=value2;" - Changes values in column1 to value1, where column2 equals value2.

Indented line

"UPDATE table SET column1=value1;" - Sets all values in the table, in column1, to value1 (regardless of their current value).

Indented line

"UPDATE table SET column1=value1, column2=value2;" - Changes column1 to value1 and column2 to value2.
