Question

I have five columns and i want to search data from five columns but column values can be more than 5, its not fixed.

Example

column name

first-name,last-name,subject,result,grade.

I want to search more-than one value using sqlite.(first-name can be a,b,c,d)

How to achieve this??

Any help would be appreciated.

Using IN keyword in SQLite would allow you perform search with a set of multiple values. For example:

SELECT * FROM table WHERE first-name IN ('a', 'b', 'c', 'd');

Now what you can do is to build an input (searchable words) parameter using any loop and replace it in the IN brackets.

For example:

String names = "'a', 'b', 'c', 'd'";      /* build it through loop */

Cursor c = db.rawQuery("SELECT * FROM table WHERE first-name IN (?)",
              new String[]{names});

With multiple columns:

String names = "'a', 'b', 'c', 'd'";      /* build it through loop */

Cursor c = db.rawQuery("SELECT * FROM table WHERE first-name IN (?)
         OR last-name IN (?) OR subject IN (?) OR result IN (?) OR grade IN (?)",
         new String[]{names, names, names, names, names});
