How do you set a date range in Java?
A Java example to check if a provided date is within a range of 3 momths before and after current date.

DECLARE @MinDate DATE = ‘20140101’, @MaxDate DATE = ‘20140106’; SELECT TOP (DATEDIFF(DAY, @MinDate, @MaxDate) + 1) Date = DATEADD(DAY, ROW_NUMBER() OVER(ORDER BY a. object_id) – 1, @MinDate) FROM sys. all_objects a CROSS JOIN sys.
How do you set a date range in SQL query?

What are the best practices in SQL?
SQL Query writing: Best practices
- Do query for only the number of columns you need.
- Do NOT reuse queries unless it serves your full purpose.
- Always watch out for the execution plan and measure the time costs.
- Avoid sub queries.
- Use proper indexes (for faster search results).
How do you insert 1000 rows?
Just head over to Name Box and give values in the format ‘starting row: ending row’. For example, if you want to insert 1000 rows from row 4, then give 4:1003 and hit enter. Then it would select 1000 rows from row 4. Next, right click on selected rows and click on ‘insert’ option.
How do I make SQL insert faster?
- Use multi-row statements instead of multiple single-row statements.
- Use multi-row INSERT statements for bulk-inserts into existing tables.
- Use IMPORT instead of INSERT for bulk-inserts into new tables.
- Use batch updates to delete a large number of rows.
- Use TRUNCATE instead of DELETE to delete all rows in a table.
How do I optimize a SQL insert?
To optimize insert speed, combine many small operations into a single large operation. Ideally, you make a single connection, send the data for many new rows at once, and delay all index updates and consistency checking until the very end.
How do you optimize an insert statement?
How will you design database for fast insert?
Here are a few ideas, note for the last ones to be important you would have extremly high volumns:
- do not have a primary key, it is enforced via an index.
- do not have any other index.
- Create the database large enough that you do not have any database growth.
- Place the database on it’s own disk to avoid contention.
What is bulk insert in SQL?
