getutcdate means : Coordinated Universal Time
and return universal time regardless your time zone
but getdate return time based on your time zone:

<br />
SELECT 'SYSDATETIME()      ', SYSDATETIME();<br />
SELECT 'SYSDATETIMEOFFSET()', SYSDATETIMEOFFSET();<br />
SELECT 'SYSUTCDATETIME()   ', SYSUTCDATETIME();<br />
SELECT 'CURRENT_TIMESTAMP  ', CURRENT_TIMESTAMP;<br />
SELECT 'GETDATE()          ', GETDATE();<br />
SELECT 'GETUTCDATE()       ', GETUTCDATE();<br />
/* Returned:<br />
SYSDATETIME()            2007-05-03 18:34:11.9351421<br />
SYSDATETIMEOFFSET()      2007-05-03 18:34:11.9351421 -07:00<br />
SYSUTCDATETIME()         2007-05-04 01:34:11.9351421<br />
CURRENT_TIMESTAMP        2007-05-03 18:34:11.933<br />
GETDATE()                2007-05-03 18:34:11.933<br />
GETUTCDATE()             2007-05-04 01:34:11.933<br />
*/<br />

Thanks Reza,

Could I understand GETDATE returns machine local time?

GetDate() returns current date of your sqlserver machine(means the server where your sqlserver installed)

GETUTCDATE returns current date of the system in UTC time (Greenwich Mean Time) while GETDATE return current time in the timezone where the system is working.

Executing Multiple Oracle Procedures Parallel( not in sequence) in dotnet [modified]

12-Jan-09 22:22

Do you mean that yo will store 128 records per minute. If so, that isn't so much, but if the amount rises, I think the first bottleneck will be the program storing those records and the possible network between the program and the database. Most of the databases canhandle that amount easily as long as the commands can be delivered to them fast enough.

One consideration is also that do you insert every record separately or can you make insertions as a batch. For example SQL Server client in .Net framework has SqlBulkCopy class which might be useful. Also SqlDataAdapter can handle batches. I'm not sure what's the sitatuation with MySQL client.
