+# class pq\Cursor
+
+Declare a cursor.
+
+## Constants:
+
+* BINARY  
+  Causes the cursor to return data in binary rather than in text format. You probalby do not want to use that.
+* INSENSITIVE  
+  The data returned by the cursor should be unaffected by updates to the tables underlying the cursor that take place after the cursor was opened.
+* WITH_HOLD  
+  The cursor should stay usable after the transaction that created it was successfully committed.
+* SCROLL  
+  Force that rows can be retrieved in any order from the cursor.
+* NO_SCROLL  
+  Force that rows are only retrievable in sequiential order.
+
+> ***NOTE:***  
+  See the [notes in the official PostgreSQL documentation](http://www.postgresql.org/docs/current/static/sql-declare.html#SQL-DECLARE-NOTES) for more information.
+
+## Properties:
+
+* public (readonly) pq\Connection $connection  
+  The connection the cursor was declared on.
+* public (readonly) string $name  
+  The identifying name of the cursor.
