Im receiving an error where I am using an incorrect integer value for userID_fk and target. The error comes up for values which have an integer as their data type and if its changed to text or varchar it will state a site has been created and the siteID will increase but no other data will be included. I want the user to input their username so its matched with its userID and inserted into userID_fk through python with Tkinter.
Below is the structure for my users and sites table
users:
CREATE TABLE `users` (
`userID` int(255) NOT NULL AUTO_INCREMENT,
`userName` varchar(255) CHARACTER SET latin1 COLLATE latin1_general_cs NOT NULL,
`userPassword` varchar(225) CHARACTER SET latin1 COLLATE latin1_general_cs NOT NULL,
`Name` varchar(255) NOT NULL,
`phoneNum` text NOT NULL,
`email` varchar(230) NOT NULL,
`region` text NOT NULL,
`accessLevel` int(10) NOT NULL,
PRIMARY KEY (`userID`)
) ENGINE=InnoDB AUTO_INCREMENT=10002 DEFAULT CHARSET=utf8 ROW_FORMAT=COMPACT
sites:
CREATE TABLE `sites` (
`siteID` int(225) NOT NULL AUTO_INCREMENT,
`siteName` text CHARACTER SET latin1 COLLATE latin1_general_cs NOT NULL,
`userID_fk` int(255) NOT NULL,
`region` text NOT NULL,
`risklevel` text NOT NULL,
`siteType` text NOT NULL,
`target` int(225) NOT NULL,
PRIMARY KEY (`siteID`),
KEY `userID_fk` (`userID_fk`),
CONSTRAINT `sites_ibfk_1` FOREIGN KEY (`userID_fk`) REFERENCES `users` (`userID`) ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=COMPACT
Python code to insert a site into the sites table:
def register_site():
sitename_info = sitename2.get()
username2_info = username2.get()
region_info = region.get()
risklevel_info = risklevel.get()
sitetype_info = sitetype.get()
targetpercent_info = targetpercent.get()
# Sql code for writing the data that was written in the regsitering page.
cursor = cnn.cursor()
sitequery = "INSERT INTO `sites`(`siteID`, `siteName`, `userID_fk`, `region`, `risklevel`, `siteType`, `target`) VALUES (NULL,%s,%s,%s,%s,%s,%s)"
sitequery_vals = (sitename_info, username2_info, region_info, risklevel_info, sitetype_info, targetpercent_info)
cursor.execute(sitequery, sitequery_vals)
cnn.commit()
cursor.close()
cnn.close()
# removes the values in the entrys once the user selects that the registration was successful
sitename2_entry.delete(0, END)
region_entry.delete(0, END)
risklevel_entry.delete(0, END)
sitetype_entry.delete(0, END)
targetpercent_entry.delete(0, END)
Label(screen10, text = "Site Created", fg = "green", font = ("calibri", 11)).pack()
If username2_info is the userName, you need to get the userID from the users table:
sitequery = ("INSERT INTO `sites` (`siteName`, `userID_fk`, `region`, `risklevel`, `siteType`, `target`) "
"SELECT %s, `userID`, %s, %s, %s, %s FROM `users` WHERE `userName` = %s")
sitequery_vals = (sitename_info, region_info, risklevel_info, sitetype_info, targetpercent_info, username2_info)
cursor.execute(sitequery, sitequery_vals)
cnn.commit()
I am using prepared statements for my SQL insert query, and I am receiving the message that there is an error in the syntax.
I have tried using PHPMyAdmin and used the same query in that and substituted the placeholders for the real values and that query worked fine, therefore I am assuming it is something to do with my use of prepared statements.
def create_user(f_name, s_name, email, sex, dob, mobile=None):
try:
conn = mysql.connector.connect(host=host, user=user, passwd=password) # create a connection to the database
cursor = conn.cursor(prepared=True) # Creates a cursor that is expecting prepared
if mobile is not None: # if the mobile number is specified
sql_parameterized_query = ("""BEGIN;
INSERT INTO users (FirstName, Surname, Email, Dob, Gender, Mobile)
VALUES (%s, %s, %s, %s, %s, %s);
INSERT INTO passwords (UserID, hashedPass)
VALUES (LAST_INSERT_ID(),%s);
COMMIT;""")
query_array = (f_name, s_name, email, date_sql_format(dob), sex, mobile, hash_user_password)
else: # if the mobile number is not specified
sql_parameterized_query = ("""BEGIN;
INSERT INTO users (FirstName, Surname, Email, Dob, Gender)
VALUES(%s, %s, %s, %s, %s);
INSERT INTO passwords (UserID, hashedPass)
VALUES(LAST_INSERT_ID(),%s);
COMMIT;""")
query_array = (f_name, s_name, email, date_sql_format(dob), sex, hash_user_password) # Init array of values
cursor.execute(sql_parameterized_query, query_array) # Execute query
conn.commit()
I would like it to insert the details for a new user into the database all fields are required excluding the mobile phone number, that is why I have used the if statement to separate them, if this is poor practice then please guide me in the correct direction for that too as I could not find a more elegant way of solving that issue, anyway, when calling the function like so create_user("Ollie", "Pugh", "oliver.pugh#icloud.com", "M", "22-04-2001")
The variable query_array has the value of ('Ollie', 'Pugh', 'oliver.pugh#icloud.com', '2001-04-22', 'M', '$2b$12$RU9FRcNjgHlC78kjZA5OIeqT1s1K2LHndC2iDK8mcqkadGc8d9XO2')
The message I receive is: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'INSERT INTO users (FirstName, Surname, Email, Dob, Gender)' at line 2
The structure of the table Users is:
CREATE TABLE `users` (
`UserID` int(11) NOT NULL AUTO_INCREMENT,
`FirstName` varchar(255) NOT NULL,
`Surname` varchar(255) NOT NULL,
`Email` varchar(255) NOT NULL,
`Dob` date NOT NULL,
`Gender` char(1) NOT NULL,
`Mobile` varchar(11) DEFAULT NULL,
`timeOfCreation` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
`Authority` varchar(255) NOT NULL DEFAULT 'User',
PRIMARY KEY (`UserID`)
) ENGINE=InnoDB AUTO_INCREMENT=23 DEFAULT CHARSET=latin1
The solution to my problem was to create a procedure, I named it CreateUser and consisted of:
BEGIN
START TRANSACTION;
IF mobile = "NULL" THEN
SET mobile = null;
END IF;
INSERT INTO `cl43-flexfit`.users (FirstName, Surname, Email, Dob, Gender,Mobile)
VALUES (f_name, s_name, email, dob, gender, mobile);
INSERT INTO `cl43-flexfit`.passwords (UserID, hashedPass)
VALUES (LAST_INSERT_ID(), passhash);
COMMIT;
END
And I have modified the python script to have two cursors as I could not use a USE statement within the procedure nor could I use one with a cursor that was configured for prepared statements.
try:
conn = mysql.connector.connect(host=host, user=user, passwd=password) # create a connection to the database
cursor = conn.cursor() # Have to have two as you can not select database with a prepared cursor
prep_cursor = conn.cursor(prepared=True) # Creates a cursor that is expecting prepared
if mobile is None: # if the mobile number is not specified
mobile = "NULL" # This is recognised as null in the procedure
sql_parameterized_query = "CALL CreateUser(%s, %s, %s, %s, %s, %s, %s)" # Calls the create user procedure
query_array = (f_name, s_name, email, date_sql_format(dob), sex, mobile, hash_user_password)
cursor.execute("USE `cl43-flexfit`;")
prep_cursor.execute(sql_parameterized_query, query_array) # Execute query
conn.commit()
I'm sure there are still better ways of doing this, but this does the job for now.
I created a table with mysql.connector like this:
CREATE TABLE %s (ID int NOT NULL AUTO_INCREMENT,
date VARCHAR(200) NOT NULL default'{}',
s_time VARCHAR(30) NOT NULL default'{}',
shukkin VARCHAR(30) NOT NULL default'{}',
taikin VARCHAR(30) NOT NULL default'{}',
t_time VARCHAR(30) NOT NULL default'{}',
shucchou VARCHAR(30) NOT NULL default'{}',
shucchou_time VARCHAR(30) NOT NULL default'{}',
shucchou_kaeri_time VARCHAR(30) NOT NULL default'{}',
PRIMARY KEY (ID))" %val_s
And I'm trying to insert there and date now with this code block
now2 = datetime.datetime.now()
now = now2.strftime("%m/%d/%Y")
but when I insert to date VARCHAR(200) it becomes something like this
0.000742942050520059
And I dont know where is a problem... I tried inserting directly like this 06/04/2019 but when I selected * from table it shows same number as above.
Can someone please tell me where is a problem?
now2 = datetime.datetime.now()
now = now2.strftime("%m/%d/%Y")
now_t = now2.strftime("%H:%M:%S")

I don't use markdown very much, my code indent is not a problem, I pasted code to stackoverflow some indentation problems, please ignore.
I made a mistake when I created the data table using pymysql:
Create table failure, cause: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''JD_phone' (\n id INT (15) PRIMARY KEY,\n price VARCHAR (15) NOT NUL' at line 1")
Insert data failure, cause： 'tbname'
So is my SQL statement wrong, and how do I write the remaining decimal point in the SQL statement?
Oh, I've solved it, by testing every field test,I changed the long field to longs to successfully create the data table, which should be the reason for the built-in name conflict with mysql.
The table is successful and the name is JD_phone
