Class

public class TEZ_AC_pageblocktablecolumn{
    public list<contact> con{get;set;}
    public TEZ_AC_pageblocktablecolumn (){
        con=[select id, name from contact limit 1000];

OFFSET Added to SOQL

Use OFFSET to specify the starting row offset into a query’s result set. OFFSET is helpful for paging into large result sets and quickly jumping to a particular subset rows in large results. For example, the following SOQL query returns a result set that skips the first 100 rows of the full query results:

SELECT Name FROM Merchandise__c WHERE Price__c > 5.0 ORDER BY Name LIMIT 50 OFFSET 100

The resulting set of 50 records begins with the 101st record in the query result set.
