Do you know how to create indexs in SQL Server tables that span
multiple columns?
CREATE UNIQUE NONCLUSTERED INDEX newKey ON YourTable
(
empNumber,
kDate,
shiftNo
) WITH( STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF,
ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
GO
In your where clause :
Where empNumber = YourmakeshiftValue
and kDatebetween StartOfDay and EndOfDay
and shftno = 1
As a heads up. This index may never get used if the table is joined
so all of this is mute.
