}

Samples

You can take a look at the sample app located on this project.

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 ")
     .like("TEST2", "%fox%")
     .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");

Update

    ContentValues cv =  SqlParser.content().add("NAME", "John")
	          .add("CITY", "New York")
    		  .add("STATE", "New Jersey").get();

     yourDb.update(tableName, cv, rowId + " = ?", new String[]{String.valueOf(yourId)});
