search column in other column sql

Question

I have the following query:

SELECT 
    Table1 . *
FROM
    Table1
        inner JOIN
    Table2 ON Table1.Column1 = Table2.Column2

I want to change the query to find NOT only a macth between Table1.Column1 to Table2.Column2 but to find all data where Table1.Column1 is a string inside Table2.Column2 .

What I need to do?

Answer 1

How about something like

SELECT 
    Table1 . *
FROM
    Table1
        inner JOIN
    Table2 ON Table1.Column1 LIKE CONCAT('%',Table2.Column2,'%')

Answer 2

If it's SQL SERVER , use CHARINDEX

SELECT 
Table1 . *
FROM
Table1
    inner JOIN
Table2 ON CHARINDEX(Table1.Column1, Table2.Column2) > 0

Answer 3

Change the ON clause to

SqlServer

ON Table2.Column2 LIKE '%'+Table1.Column1+'%'

MySQL

ON Table2.Column2 LIKE CONCAT('%',Table1.Column1,'%') 

Answer 4

Try this

SELECT 
    Table1.*
FROM
    Table1
        inner JOIN
    Table2 ON T Table2.Column2 Like '%' + Table1.Column1 + '%'
