How can I optimize/refactor a TSQL “LIKE” clause?

Question

I have a table with 117000 or so records. I need to perform a search that checks 3 separate fields for a given string pattern.

My where clause is as follows:

Answer 1

If you can't use FullTextSearch you can increase speed in 10 times. Do next:

1 Add calculated field:

alter table TableName
add CalculatedColumnName as upper(Column1 + '|' + Column2...) collate Latin1_General_100_Bin2
persisted;

2 Add index for calculated field:

create nonclustered index IDX_TableName_CalculatedColumnName
on TableName(CalculatedColumnName);

3 Change your query text

select count(*)
from TableName
where CalculatedColumnName like '%' + upper(@ParameterValue) + '%' collate Latin1_General_100_Bin2
