Usage

from simplemysql import SimpleMysql

db = SimpleMysql(
                host="localhost",
                db="mydatabase",
                user="username",
                passwd="password"
)

# insert a record to the *books* table
db.insert("books", {"type": "paperback", "name": "Time Machine", "price": 5.55, year: "1997"})

book = db.getOne("books", ["name"], ["year = 1997"])

print "The book's name is " + book.name

Query methods

insert(), update(), delete(), getOne(), getAll(), query()

insert(table, record{})

Inserts a single record into a table.

db.insert("food", {"type": "fruit", "name": "Apple", "color": "red"})
db.insert("books", {"type": "paperback", "name": "Time Machine", "price": 5.55})

update(table, row{}, condition[])

Update one more or rows based on a condition (or no condition).

# update all rows
db.update("books", {"discount": 0})

# update rows based on a simple hardcoded condition
db.update("books",
        {"discount": 10},
        ["id=1"]
)

# update rows based on a parametrized condition
db.update("books",
        {"discount": 10},
        ("id=%s AND year=%s", [id, year])
)

insertOrUpdate(table, row{}, key)

Insert a new row, or update if there is a primary key conflict.

# insert a book with id 123. if it already exists, update values
db.insert("books",
                {"id": 123, type": "paperback", "name": "Time Machine", "price": 5.55},
                "id"
)

getOne(table, fields[], condition[], order[], limit[])

getAll(table, fields[], condition[], order[], limit[])

Get a single record or multiple records from a table given a condition (or no condition). The resultant rows are returned as namedtuples. getOne() returns a single namedtuple, and getAll() returns a list of namedtuples.

book = db.getOne("books", ["id", "name"])

# get a row based on a simple hardcoded condition
book = db.getOne("books", ["name", "year"], ("id=1"))

# get a row based on a simple hardcoded condition
book = db.getOne("books", ["name", "year"], ("id=1"))

# get multiple rows based on a parametrized condition
books = db.getAll("books",
        ["id", "name"],
        ("year > %s and price < 15", [year, 12.99])
)

# get multiple rows based on a parametrized condition with an order and limit specified
books = db.getAll("books",
        ["id", "name", "year"],
        ("year > %s and price < 15", [year, 12.99]),
        ["year", "DESC"],       # ORDER BY year DESC
        [0, 10]                 # LIMIT 0, 10
)

lastId()

Get the last insert id

delete(table, fields[], condition[], order[], limit[])

Delete one or more records based on a condition (or no condition)

# delete all rows
db.delete("books")

# delete rows based on a condition
db.delete("books", ("price > %s AND year < %s", [25, 1999]))

query(table)

Run a raw SQL query. The MySQLdb cursor is returned.

db.query("DELETE FROM books WHERE year > 2005")
