Delphi 7 TAdoQuery too slow

原文 2017-05-03 15:03:00 3 1 sql-server/ delphi-7/ ado/ tadoquery

I'm using Delphi 7 and SQL Server 2008. The connection is AdoConnection and the Query component I'm using is TAdoQuery.

When i run the following simple query in sql server

select FMStreamid, Latitude, Longitude, RealTime from tblFMStream where vehicleid = 2

it takes 2 sec to execute in sql server (see pic) sql server response

However running the same query in Delphi takes around 15 seconds to Open. Does anyone know how to speed that? Thanks

他们在Delphi上花费的额外时间可能是AdoConnection正在使用的提供程序和打开查询时触发的数据集事件的结合

SQLCLR running too slow

SQL connection is too slow

Select Max() is too slow

Linq ToLookUp too slow

ToUniversalTime() - too slow?

Parameterized query is too slow

Executing the contents of a memo on a TADOQuery

PHP5 - SQLSRV too slow

SQL Azure response is too slow

Looping Stored Procedure too slow
