+
+# Implementation
+
+### Select
+
+##### Working with columns.   
+
+    SqlParser.query()
+       .col("A")
+       .col("B")
+       .col("C", "NICK")
+       .col("ALIAS","D", "NICK")
+       .cols("E", "F", "G")
+       .sum("H").count()
+       .max("I")
+       .table("YOUR_TABLE", "T")
+       .build();
+
+   > Output: SELECT A, B, C AS NICK, ALIAS.D AS NICK, E, F, G, SUM(H), COUNT(*), MAX(I) FROM  YOUR_TABLE T
+
+
+##### More than one table.   
+
+     SqlParser.query()
+        .col("P", "NAME", "PRODUCT_NAME")
+        .col("C", "NAME", "COLOR_NAME")
+        .table("PRODUCT", "P")
+        .table("COLOR", "C")
+        .equal("P", "IDCOLOR", "C","ID")
+        .build();
+
+  > Output: SELECT P.NAME AS PRODUCT_NAME, C.NAME AS COLOR_NAME FROM PRODUCT P, COLOR C WHERE P.IDCOLOR = C.ID
+
+
+##### Exists or not exists.   
+   
+        SqlParser.query()
+           .table("TABLE", "T")
+           .exists(Sql.query().table("XTABLE", "XT").equal("XT", "FIELD", "T","FIELD").build())
+           .notExists(Sql.query().table("YTABLE", "YT").equal("YT", "FIELD", "T","FIELD").build())
+           .build();
+  
+  > Output: SELECT  *  FROM  TABLE T WHERE  EXISTS (SELECT  *  FROM  XTABLE XT WHERE XT.FIELD = T.FIELD) NOT EXISTS (SELECT  *  FROM  YTABLE YT WHERE YT.FIELD = T.FIELD)
+  
+  
+##### Greater, smaller, equal, trim.   
+  
+      SqlParser.query()
+         .table("TABLE")
+         .greater("THE_COLUMN" , 9)
+         .and()
+         .smallerEqual("THE_COLUMN", 40)
+         .or()
+         .equalTrim("TEST", " RAW ")
+         .build();
+       
+   > Output: SELECT  *  FROM  TABLE WHERE THE_COLUMN > 9 AND THE_COLUMN <= 40 OR TRIM(TEST) = 'RAW'
+       
+### Delete.
+
+     SqlParser.delete("TABLE").smallerEqual("COL", 0).build();     
+     
+   > Output: DELETE FROM TABLE WHERE COL <= 0
+   
+### Insert.
+   
+      SqlParser.insert("TABLE")
+         .col("A", 1)
+         .col("B", "TEST")
+         .build();
+
+> Output: INSERT INTO TABLE(A,B) VALUES(1,'TEST');
+         
+### Create.
+
+     SqlParser.create("TABLE")
+                .pk("ID")
+                .num("CODE")
+                .num("TYPE")
+                .flo("PRICE")
+                .flo("QUANTITY")
+                .build();
+                
+  > Output: CREATE TABLE TABLE (ID INTEGER PRIMARY KEY,CODE INTEGER,TYPE INTEGER,PRICE FLOAT,QUANTITY FLOAT);
+
+         
+### Cursor.
+
+     Cursor cp = SqlParser.cursor(yourCursor);
+
+        if (cp.binded()) 
+            Product product = new Product(cp.num("ID")
+                                        , cp.num("CODE")
+                                        , cp.flo("STOCK")
+                                        , cp.flo("")
+                                        , cp.str("NAME"));
+                                        
+                                        
+### ContentValues.
+       
+	 SqlParser.content().add("NAME", "John")
+		          .add("CITY", "New York")
+        		  .add("STATE", "New Jersey");
