SQL Server 2014 Word Count

Question

I have a SQL Server database that I\'m searching for keywords.

All I need to know is how many of the keywords appear in a column.

For example

Answer 1

You can use a string splitter for this. Here is the DelimitedSplit8K function by Jeff Moden.

DECLARE @str VARCHAR(8000) = 'I like red shoes and green shoes, but green are my favourite'

SELECT
    COUNT(DISTINCT ITEM)
FROM dbo.DelimitedSplit8K(@str, ' ')
WHERE
    Item IN('red', 'green', 'blue')
