Set Date Ranges
When writing a query, you frequently need to retrieve data from a range of dates such as the last week, month, or quarter. Identifying the actual date range to use is time consuming, confusing, and is often error prone.
Note: The date range format is specific to Toad. If you want to view the syntax of the date range so you can copy it to another application such as SQL*Plus, click the date range link in the Query tab, as illustrated in the following:
ScenarioYou need to create a query that retrieves a list of the orders that were placed last year. In the past, you hard coded the dates to create the following statement: SELECT ORDER_NUM, BOOKINGS_DATE With Toad, you simply select Last year to dynamically insert the correct SQL. This ensures that your query is valid regardless of the date. The following displays the revised query: SELECT ORDER_NUM, BOOKINGS_DATE The criteria is empty and contains two single quotes without a space. Toad inserts the correct SQL between these quotes when you execute the query. |
The following date range commands are available and can also be used in the Editor:
|
/*Today*/ |
/*Last 15 days*/ |
/*Last quarter*/ |
|
/*Yesterday*/ |
/*Last 30 days*/ |
/*Current year*/ |
|
/*Current week*/ |
/*Current month*/ |
/*Last year*/ |
|
/*Last week*/ |
/*Last month*/ |
|
|
/*Last 7 days*/ |
/*Current quarter*/ |
|
|
Note: These commands are case sensitive. | ||
