How to concatenate % and column name in a LIKE statement

Question

I'm trying this:

SELECT FacilityID, FacilityName, CMSProviderID, [Provider Number] 
FROM G2_Facility, SCIPHospitalCompare
WHERE [Provider Number] LIKE '%' + CMSProviderID + '%';

And I get:

Msg 245, Level 16, State 1, Line 1
Conversion failed when converting the varchar value '%' to data type int.

What am I doing wrong? I saw many examples doing stuff like this but for some reason it simply does not work at all.

Thanks!

Answer 1

I assume that either [Provider Number] or CMSProviderID is a numeric field?

Convert the numeric field to a string to compare the two:

SELECT FacilityID, FacilityName, CMSProviderID, [Provider Number]  
FROM G2_Facility, SCIPHospitalCompare 
WHERE CAST([Provider Number] as nvarchar(50)) LIKE 
    '%' + CAST(CMSProviderID as nvarchar(50)) + '%';
