How does query with multiple where condition work in postgresql?

@deron 

In PostgreSQL, you can use the "AND" and "OR" operators to create queries with multiple where conditions.

For example, if you want to retrieve data from a table where both conditions are true, you can use the following query:

1
2

SELECT * FROM table_name
WHERE condition1 AND condition2;

If you want to retrieve data where at least one of the conditions is true, you can use the following query:

1
2

SELECT * FROM table_name
WHERE condition1 OR condition2;

You can also combine multiple conditions using parentheses to specify the order of evaluation:

1
2

SELECT * FROM table_name
WHERE (condition1 AND condition2) OR condition3;

By using these operators and parentheses, you can create complex queries with multiple where conditions in PostgreSQL.
