Does pyodbc support any form of named parameters?

问题

I know sqlite3 has

data = {'test_col': 012345679}
sqlite3_conn.execute("""
    UPDATE test_db SET test_col = :test_col
    ;""", data)

and mysql-connector-python has

data = {'test_col': 012345679}
mysql_conn.execute("""
    UPDATE test_db SET test_col = %(test_col)s
    ;""", data)

but does pyodbc support any form of named parameters? I like being able to just pass a dict to the execute method. It is very convenient, and with some of my queries, such as INSERT INTO ... ON DUPLICATE KEY UPDATE, it is needed.

回答1:

It doesn't support named parameters, but bound parameters passed in the correct order are fairly straightforward:

x = "This"
y = 345

mssql_cur.execute("SELECT * FROM mytable WHERE colx = ? AND coly = ?", x, y)

or

mssql_cur.execute("SELECT * FROM mytable WHERE colx = ? AND coly = ?", (x, y))

More details and options here, such as passing executemany parameters:

Good luck!
