Shorten SQL Syntax of LIKE Clause to IN Clause

Question

In SQL, Is there any way to Shorten syntax From

Select * from TableName
where ColumnName like \'%A%\' or ColumnName like \'%B\' or ColumnName like \'C%\'


        

Answer 1

No there isn't a way to combine LIKE with IN directly

There are ways around this, like this example for SQL Server

Select *
from
   TableName T
   JOIN
   (VALUES ('%A%'),('%B'),('C%')) AS X(Expression) ON T.ColumnName LIKE X.Expression

This changes multiple OR search conditions into rows and a JOIN

Or you can use a UNION to combine several queries in one

Select * from TableName
where ColumnName like '%A%'
union
Select * from TableName
where ColumnName like '%B'
union
Select * from TableName
where ColumnName like 'C%'
