what the solution ?
Like the error says, you should
change AGE INI to AGE INT.

i have a database and i give it name "test" then
i try to change the database name using python code, but when i run the program the result give me an error warning. here is my code :
def changedb_name():
import mysql.connector
mydb = mysql.connector.connect(host = 'localhost', user='root', password ='')
mycursor = mydb.cursor()
mycursor.execute('ALTER DATABASE test RENAME to test1')
changedb_name()
here is the error warning :

From where did you find the SQL syntax to ALTER DATABASE...RENAME... ? It seems to me your reference is flawed; that isn't any MySQL syntax I'm familiar with. I believe the ability briefly existed for the blink of an eye. A bit of an internet history search confirms that it hasn't been part of MySQL (pdf) syntax in over 10 years (hat tip to #zloctb).
You can't rename a database in pure SQL. The usual workaround is to export to SQL and re-import to the new database.
SQLAlchemy and SQLite errors appearing on PythonAnywhere but it was fine on localhost.
So I just uploaded my Flask site to pythonanywhere, and when I tried to access it it can't access my database, but is getting a bunch of errors instead.
2021-01-30 10:42:05,740: Exception on /m/550 [GET]
Traceback (most recent call last):

sqlite3.OperationalError: near "(": syntax error
**NO MATCH**
I was not getting these exceptions on my local computer. A little googling and it seems like this is because PA uses an older version of SQLite? Which seems a bit stupid to begin with but it also seems like I can't update it?
So I'm wondering if there is some smart solution to this, or if it would perhaps be easier to switch to MySQL? Would there be other problems in doing that instead? Or do I just need to switch out the SQLALCHEMY_DATABASE_URI to fit MySQL instead? My Current one looks like this:
SQLALCHEMY_DATABASE_URI = 'sqlite:////home/movieelo/cinelow/my_server/database/database.db'
SQLALCHEMY_TRACK_MODIFICATIONS = False
All help and guidence will be greatly appreciated!
UPDATE:
I managed to switch to MySQL but am still getting SQL syntax related errors, such as:
mysql.connector.errors.ProgrammingError: 1064 (42000): 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 '(PARTITION BY
movie_category_scores.category_id ORDER BY movie_category_scores.s' at line 2
**NO MATCH**
UPDATE 2
I think that I have now identiefied the single function that is causing the errors, and it looks like this:
def get_top_movies_by_category(category_id):
query = db.session.query(
MovieCategoryScores,
func.rank()\
.over(
order_by=MovieCategoryScores.score.desc(),
partition_by=MovieCategoryScores.category_id,
)\
.label('rank')
).filter(MovieCategoryScores.votes >= 10)
# now filter
query = query.filter(MovieCategoryScores.category_id == category_id)
query = query.order_by(MovieCategoryScores.category_id, 'rank')
movies = query.all()
return movies
Which generates this error:

Giles Thomas (of PythonAnywhere) confirmed that the SQLite version available on PythonAnywhere doesn't support window functions.
Window functions were added to SQLite version 3.25.0. In the future, you can check whether the SQLite version included with your Python installation supports windows functions by running:
import sqlite3
if sqlite3.sqlite_version_info > (3, 25, 0):
print("Window functions are supported!")
else:
print("Window functions are not supported :(")

i tried a solution (given below , taken from the link https://bugs.mysql.com/bug.php?id=66030&thanks=3¬ify=195). but it didn't help. I still get the same error. Please help me.
solution:
// We'll need some help from you to diagnose this one. With a text editor, open the /Applications/MySQLWorkbench.app/Contents/PlugIns/db_mssql_grt.py file
and around line 174 you'll find a line that looks like:
ver_string = execute_query(connection, "SELECT SERVERPROPERTY('ProductVersion')").fetchone()[0]
Change that to:
ver_string = execute_query(connection, "SELECT CAST(SERVERPROPERTY('ProductVersion') AS VARCHAR)").fetchone()[0]
Then save and retry. Thanks! //

Where is the error and what is the fix?
It seems that mysql doesn't like the INT(5). Try to use SMALLINT.
More info: http://dev.mysql.com/doc/refman/5.7/en/integer-types.html
The DOMAIN column has an ) that is not needed.
The POSTAL_CODE column has a default clause, but no default value.
I'm not sure that you need multiple " to begin and start the query.
I believe you have an extra parenthesis in line 4:
DOMAIN varchar(255) DEFAULT NULL) ,
Remove it and try it again.

ProgrammingError: (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 '(60)) AS anon_1' at line 1")
Looks like MySQL is reporting a syntax error in one of your SQL statements:
<snip>
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
'(60)) AS anon_1' at line 1
</snip>
It looks like MySQL is objecting to a statement that includes the string:
(60)) AS anon_1
NOTE: I am not familiar with Sqlalchemy, but it looks to me like the exception (the SQL error from the statement) is getting propagated up to the handler specified in the connection.
FOLLOWUP: It's likely that a query that Sqlalchemy is executing is not compatible with the older version of MySQL. Looks like it's in the "_check_unicode_returns" function.
Have you tried disabling unicode support?
conn_str = "mysql://user:pass#192.168.171.233/dbd?use_unicode=0"
