Compare Columns Where One is Similar to Part of Another

Question

I\'m trying to write a Select statement where I can see if one column is like part of another.

tblNames 
ID    FullName                   FirstName
1     Mr.         


        

Answer 1

Oracle expects number when + is used. For string, please use the samle below :

SELECT ID, FullName, FirstName
FROM tblNames
WHERE FullName like '%' || FirstName||'%'

To compare one column of a table to a column of another table, please do the following

select a.*,table_2_col_1, table_2_col_2 from (select table_1_col_1, table_1_col_2 from table_1 where
)  a, table_2 where   table_1_col_1 like '%' || table_2_col_1 ||'%'
