Hi,
Thank you for your help.
Is there a means of simplifying the following UNION
statement?

select * from D_Vendors where VendorName like '%Criteria%'
UNION
select * from D_Vendors where VendorName like '%Alistair-Hugo%'
UNION
select * from D_Vendors where VendorName like '%Elizabeth Higgins%'
UNION
select * from D_Vendors where VendorName like '%Focus Vision%'
UNION
select * from D_Vendors where VendorName like '%Redhead%'
UNION
select * from D_Vendors where VendorName like '%Research House%'
UNION
select * from D_Vendors where VendorName like '%Spectrum%'
UNION
select * from D_Vendors where VendorName like '%Take Note%'
UNION
select * from D_Vendors where VendorName like '%Transcription Global%'
UNION
select * from D_Vendors where VendorName like '%Viewpoint%'
UNION
select * from D_Vendors where VendorName like '%White Rooms%'
UNION
select * from D_Vendors where VendorName like '%Wyoming%'
)

best way to do this is to pass the string values as a comma seperated list like


DECLARE @SearchList varchar(1000)
SET @SearchList='Criteria,Alistair-Hugo,Elizabeth Higgins,...,Wyoming'

and use like

SELECT d.*
FROM D_Vendors d
INNER JOIN dbo.ParseValues(@SearchList,',')f
ON d.VendorName LIKE '%' + f.Val + '%'

ParseValues can be found in below link

select * from D_Vendors
where VendorName like '%Criteria%'
or VendorName like '%Alistair-Hugo%'
or VendorName like '%Elizabeth Higgins%'
...

==========================================
Cursors are useful if you don't know sql.
SSIS can be used in a similar way.
