In SQL I (sadly) often have to use “
LIKE” conditions due to databases that violate nearly every rule of normalization. I can’t change that right now. But that’s irrelevant to the question.
Further, I often use conditions like
WHERE something in (1,1,2,3,5,8,13,21) for better readability and flexibility of my SQL statements.
Is there any possible way to combine these two things without writing complicated sub-selects?
I want something as easy as
WHERE something LIKE ('bla%', '%foo%', 'batz%') instead of this:
WHERE something LIKE 'bla%' OR something LIKE '%foo%' OR something LIKE 'batz%'
I’m working with SQl Server and Oracle here but I’m interested if this is possible in any RDBMS at all.
There is no combination of LIKE & IN in SQL, much less in TSQL (SQL Server) or PLSQL (Oracle). Part of the reason for that is because Full Text Search (FTS) is the recommended alternative.
Both Oracle and SQL Server FTS implementations support the CONTAINS keyword, but the syntax is still slightly different:
WHERE CONTAINS(t.something, 'bla OR foo OR batz', 1) > 0
WHERE CONTAINS(t.something, '"bla*" OR "foo*" OR "batz*"')
The column you are querying must be full-text indexed.
