if where clause contains more than one equal condition on the same column, no rows are returned for the count query

SELECT count FROM "table1" as Something WHERE (Something."column1" = 'gaurav' AND Something."column1" = 'chaudhary')
does not return any row when this is fired through a prepared statement.
#Table table does not have any value given in the where clause
Though the query
SELECT count FROM "table1" as Something WHERE (Something."column1" = 'gaurav')
works and returns a row with 0 as value.

Though this is a minor issue but due to this, our search is failing if the user gives matching columns in the criteria.
