SQL query taking longer time to execute - sql

Question

I'm trying to execute the query. It take 32 min to execute. I have tried NOLOCK but only optimized it with 3 min.
the query is given below:-
SELECT PO.payday, PO.facility, PO.department, PO.workcenter, PO.shift, PO.team, PO.orderno, PO.fg_productno,
PO.sfg_productno, NoCarton = '1', NoPack = 5, NoCigarette = PO.nocigarette, VNC.sampleid, VNC.comment,
VNC.createdby, SampleDateTime = dbo.AF_GetUTCToLocal(VNC.UTCStartDate),
SampleTime = Cast(CONVERT(CHAR(10), VNC.utcstartdate, 101) AS DATETIME), VNC.ncgroup, VNC.productcomponent,
VNC.nc, VNC.ncname, VNC.weightingfactor, VNC.ConsumerSensitive, VNC.[lowunits], VNC.[low %], VNC.[highunits],
VNC.[high %], VNC.vqi, VNC.deepcontrol,

As per your query filter and columns needed, please make index on respected columns.
By default SQL will create clustered index on your primary key, but you may create some other unclustered index on your table to make your execution faster.
You may find this link for your reference or Google it there are hundreds of article available on Internet for same.
