How do you select a random rows from a table?
For example, if there are 1000 rows in a table matching the criteria that I want, I want to select just 20 random ones.
Like TOP, but random.
Thanks, and this is for SQL Server CE 3.5!
回答1:
How about this?
SELECT TOP(20) * FROM myTable ORDER BY NEWID()
回答2:
How about SELECT * FROM tbl_name ORDER BY RAND() LIMIT 0,20;
However if your db is with million rows Both newid() and rand() would perform slow.
