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")
