I have written eight source code
to insert some value to a database called "TA" in one table called "8box". I am planning to run this eight source code
at the same time,and then this eight source code
keeps storing data in database in almost one hour. I wrote this code for collecting data, and each of this eight source code
have the same syntax to insert values to "8box"
I want to run this eight source code
at the same time to be able to collect data.
I tried this and the result is that the database is just filled with values from first source code, none values from another source stored in database
What should i do ?
waktu=time.strftime('%Y-%m-%d %H:%M:%S')
con = mdb.connect('localhost', 'root', 'qwer1234', 'TA');
with con:
cur = con.cursor()
#cur.execute("DROP TABLE IF EXISTS 8Box")
#cur.execute("CREATE TABLE 8Box (Name VARCHAR(25),Lot_Bid INT,Bid INT,Offer INT,Lot_Offer INT,Time DATETIME)")
cur.execute("INSERT INTO 8Box VALUES (%s,%s,%s,%s,%s,%s)",(name_new,lot_bid_1_new,bid_1_new,off_1_new,lot_off_1_new,waktu))
cur.execute("INSERT INTO 8Box VALUES (%s,%s,%s,%s,%s,%s)",(name_new,lot_bid_2_new,bid_2_new,off_2_new,lot_off_2_new,waktu))
cur.execute("INSERT INTO 8Box VALUES (%s,%s,%s,%s,%s,%s)",(name_new,lot_bid_3_new,bid_3_new,off_3_new,lot_off_3_new,waktu))
cur.execute("INSERT INTO 8Box VALUES (%s,%s,%s,%s,%s,%s)",(name_new,lot_bid_4_new,bid_4_new,off_4_new,lot_off_4_new,waktu))
cur.execute("INSERT INTO 8Box VALUES (%s,%s,%s,%s,%s,%s)",(name_new,lot_bid_5_new,bid_5_new,off_5_new,lot_off_5_new,waktu))
cur.execute("INSERT INTO 8Box VALUES (%s,%s,%s,%s,%s,%s)",(name_new,lot_bid_6_new,bid_6_new,off_6_new,lot_off_6_new,waktu))
cur.execute("INSERT INTO 8Box VALUES (%s,%s,%s,%s,%s,%s)",(name_new,lot_bid_7_new,bid_7_new,off_7_new,lot_off_7_new,waktu))
cur.execute("INSERT INTO 8Box VALUES (%s,%s,%s,%s,%s,%s)",(name_new,lot_bid_8_new,bid_8_new,off_8_new,lot_off_8_new,waktu))
cur.execute("INSERT INTO 8Box VALUES (%s,%s,%s,%s,%s,%s)",(name_new,lot_bid_9_new,bid_9_new,off_9_new,lot_off_9_new,waktu))
cur.execute("INSERT INTO 8Box VALUES (%s,%s,%s,%s,%s,%s)",(name_new,lot_bid_10_new,bid_10_new,off_10_new,lot_off_10_new,waktu))
You should use the MySQLdb
interface and not the _mysql
interface. I would code it as:
cn = MySQLdb.connect(...)
c = cn.cursor()
try:
c.executemany("""
INSERT INTO 8Box VALUES (%s,%s,%s,%s,%s,%s)
""", [
(name_new,lot_bid_1_new,bid_1_new,off_1_new,lot_off_1_new,waktu),
(name_new,lot_bid_2_new,bid_2_new,off_2_new,lot_off_2_new,waktu),
# .. etc.
(name_new,lot_bid_10_new,bid_10_new,off_10_new,lot_off_10_new,waktu)
])
cn.commit()
except:
cn.rollback()
raise
