Database select statement, trying to use wildcards to display specific rows [duplicate]
This question already has an answer here:
Is storing a delimited list in a database column really that bad?
10 answers
I am trying to select all airlines where has the value 'Air Canada Rouge' for example, in the Airline columns there is sometimes concatenated values such as Air Canada, Air Canada Rouge, Air Transat. An example of the select statement I am currently using is:
select * from crs where Airline LIKE '%airlineName' OR Airline LIKE
'airlineName,%' OR Airline LIKE ',airlineName%';
This only works for rows that have Airlines that include 2 values such as Air Canada, Air Canada Rouge.
But I need the select statement to fetch rows with columns that has values that include 3 or 4 concatenated airlines.
How would I make a select statement to do this?
Thank you

As you want an exact matchwhere ',' + airline + ',' like '%,airlineName,%'
- But you should normalize the data to one-item-per-row then this becomes trivial, in most cases delimited data in a column is a recipe for disaster.

As you want an exact matchwhere ',' + airline + ',' like '%,airlineName,%'
- But you should normalize the data to one-item-per-row then this becomes trivial, in most cases delimited data in a column is a recipe for disaster.
