User · Answer

First of all my Search query value is from a user s input  I have tried all the answers on this one and all the results Google have given me  90  of the answers says put        and the other 10  says a more complicated answers   For some reason all of those did not work for me   How ever I remembered that in MySQL  phpmyadmin  there is this built in search function so I tried it just to see how MySQL handles a search with an apostrophe  turns out MySQL just escaping apostrophe with a backslash LIKE        so why just I replace apostrophe with a    in every user s query   This is what I come up with   if  empty  user search              r user search   str ireplace            user search             find it    SELECT   FROM table WHERE column LIKE    r user search              results    pdo- gt prepare  find it            results- gt execute      This solves my problem  Also please correct me if this is still has security issues

SELECT   FROM TableName WHERE CHARINDEX      ColumnName   gt  0    When you have column with large amount of nvarchar data and millions of records  general  LIKE  kind of search using percentage symbol will degrade the performance of the SQL operation   While CHARINDEX inbuilt TSQL function is much more faster and there won t be any performance loss   Reference SO post for comparative view
