Question

I want to run this query in Android Application :

SELECT field1 FROM table1  
where field1 = ?(enteredField1) AND field2 = ?(enteredField2)  
AND enteredField3 BETWEEN field3 , field4  
;

my DB schema

table1(field1, field2, field3, field4, field5)  

enteredField1 , 2 , 3 = are parameters which is to be checked.

I hope I am clear with my question.

here is the function –

public boolean checkData(String task1, String dte1, String startTime1 )  
{   

        // field 1 = task , fiels 2 = dte, field 3 = startHr, field 4 = endHr  
        // enteredField 1,2,3 = task1, dte1, startTime1   
        // here I want to insert the query  

    int a = cursor.getCount();  
    if(a>0)  
    {  
        return true;  
    }  
    return false;  
}

you can use SQLiteQueryBuilder to solve your problem. Following is an example for you, hope it can help.

SQLiteQueryBuilder qb = new SQLiteQueryBuilder();
SQLiteDatabase db = null; // get your database instance here.
qb.setTables("table1");
qb.appendWhere("field1 = ? AND field2 = ?");
qb.query(db, new String[] { "field1" }, "enteredField3 BETWEEN field3 AND field4",
        new String[] { "enteredField1", "enteredField2"}, null, null, null);
