I've got a problem that I don't know how to solve, I've tried many solutions but always getting that Operational error: near...
def insert_medicine_to_table():
con = sqlite3.connect('med_db3.db')
cur = con.cursor()
table_name = 'medicines'
column_name = "présentation"
value = 'Boîte de 2 seringues pré-remplies'
cur.execute("INSERT INTO medicines {} VALUES (?)".format(column_name), value)
con.commit()
con.close()
sqlite3.OperationalError: near "présentation": syntax error
The goal here is that either the script or python has to recognize the field (column name) and insert the value into "that" field, like the following:
fields = ['présentation', 'princeps', 'distributeur_ou_fabriquant', 'composition', 'famille', 'code_atc', 'ppv', 'prix_hospitalier', 'remboursement', 'base_de_remboursement__ppv', 'nature_du_produit']
values = ['Boîte de 2 seringues pré-remplies', 'Oui', 'SANOFI', 'Héparine', 'Anticoagulant héparinique', 'B01AB01', '43.80', '27.40', 'Oui', '43.80', 'Médicament']
That is one entry in the database. The problem here is that other entries can or not have one or more values for some field, and also the fields are not presented in the same order in other entries.
It has to recognize each field in the database table and insert each value into the right column.
The problem causing your error is that your SQL isn't valid. The statement you are trying to execute is:
INSERT INTO medicines présentation VALUES (?)
The statement you want to execute is:
INSERT INTO medicines ("présentation") VALUES (?)
As far as your larger question is concerned, if you create both the list of columns ("présentation") and list of parameter markers (?) and build the query using them, you're most of the way there.
If a field can have multiple values supplied for each "entry" in your database, you may need to change your database design to handle that. You'll at least need to figure out how you want to handle the situation, but that would be a matter for a different question.

I am trying to check if a value is in SQLite with python to then either update the table if the value exists or create a new value if it is not. I have tried to create a cursor to check rows, append the rows to a list with loop, check if value exists, check the count of the rows... I seems to get hung up on the if statement when trying to access the value initialized from the query. Here is the code:
checkT = db.execute("SELECT COUNT(*) FROM trans WHERE stock=:stock AND id=:user_id", stock=request.form.get("symbol"), user_id=session["user_id"])
if checkT > 0:
print("there")
else:
print("not there")
How can I fix this? Thank you!
From the CS50 Library for Python doc for execute
Returns
for SELECTs, a list of dict objects, each of which represents a row in the result set; for INSERTs, the primary key of a newly inserted row (or None if none); for UPDATEs, the number of rows updated; for DELETEs, the number of rows deleted; for CREATEs, True on success; on error, a RuntimeError is raised
checkT is a list with one element, which is a dict with one key/value pair.
This checkT[0]['COUNT(*)'] will give the number returned from the sql. Counting the rows would not be appropriate in this case because this query will always return one row.
One hint: column names in a SELECT can be aliased, given a different name, like so:
SELECT COUNT(*) as count from....... It would just be typing convenience, because then the key in the returned dict will be count instead of COUNT(*).
Remember: in the flask run terminal there is a traceback with gives more details information on the error received (assuming "hung up" means a 500 Internal Server Error).
I have two DAC's POReceipt, and and POReceiptLine. POReceiptLine containts a field called MfrPartNbr.
I want the user to be able to lookup all the POReceipts where the POReceiptLine.MfrPartNbr is equal to an entered value.
The SQL would be
SELECT *
FROM dbo.POReceipt
WHERE POReceipt.ReceiptNbr IN
(
SELECT ReceiptNbr
FROM dbo.POReceiptLine
WHERE MfrPartNbr = 'MY_ENTERED_PART_NBR'
)
Any idea how to write the BQL Statement for this?
As stated, an inner join won't work in this case because you will receive the same POReceipt multiple times (once for each POReceiptLine). The following BQL query shows how you can get the desired results using a sub query. If mfrPartNbr is an extension field, then replace POReceiptLine.mfrPartNbr with the correct extension name (e.g. POReceiptLineExtension.mfrPartNbr).
PXSelect<POReceipt, Where<Exists<
Select<POReceiptLine,
Where<POReceiptLine.receiptNbr, Equal<POReceipt.receiptNbr>,
And<POReceiptLine.mfrPartNbr, Equal<Required<POReceiptLine.mfrPartNbr>>>>>>>>.Select(this, "MY_ENTERED_PART_NBR");
OK Here we go.
Using Kentico 11/Portal Engine (no hot fixes)
Have a table that holds Content only page Types. One field of importance is a Date and time field.
I am trying to get rows out of this table that match a certain month and year criteria. For instance give me all records where Month=2 and Year=2018. These argument will be passed via the query string
I have a custom Stored proc that I would like to receive two int(or string) arguments then return a collection of all matching rows.
I am using a RepeaterWithCustomQuery to call the procedure and handle the resulting rows. As you can see below the querystring arguments are named "year" and "monthnumber".
The Query
Me.PR.PREDetailSelect
When my Webpart is set up in this configuration I get the following error:
In my Query, I have tried:
EXEC Proc_Custom_PRDetails #MonthNumber = ##ORDERBY##; #Year = ##WHERE##<br/>
EXEC Proc_Custom_PRDetails #MonthNumber = ##ORDERBY##, #Year = ##WHERE##<br/>
EXEC Proc_Custom_PRDetails #MonthNumber = ##ORDERBY## #Year = ##WHERE##<br/>
Any help would be appreciated (Thanks in advance Brendan). Lastly, don't get too caught up in the names of specific objects as I tried to change names to protect the innocent.
Those macros for queries are not meant to be used with stor procs. The system generates this false condition 1=1 in case if you don't pass anything so it won't break the sql statement like the one below:
SELECT ##TOPN## ##COLUMNS##
FROM View_CMS_Tree_Joined AS V
INNER JOIN CONTENT_MenuItem AS C
ON V.DocumentForeignKeyValue = C.MenuItemID AND V.ClassName = N'CMS.MenuItem'
WHERE ##WHERE##
ORDER BY ##ORDERBY##
You need to convert you stor proc to SQL statement then you can use these SQL macros or use stor proc without parameters
If look at the query above top and where are not good because system will do adjustment, but you can use order by and columns, but they both must be present (I think it passes them as is):
exec proc_test ##ORDERBY##, ##COLUMNS##
Honestly I would advice against doing this, plus you won't gain much by calling stor proc.
I am trying to reference dynamic tables and fields in a tkinter GUI project using MySQLdb. Using psycopg2.sql to handle an insert statement.
The user select a code, size and color and inputs a quantity. The table names are made up of the size and the code (eg. size-small and code-1111, table_name=small1111). Then the color is the column name and the quantity is an integer entered into the field. The inputs are saved in a dictionary (tdict) when the user selects them. And the dictionary elements are called to be saved in the database table.
table_name = tdict['Size']+tdict['Code']
stmnt = ("INSERT INTO {} (%s, Date) VALUES(%s, %s)").format(sql.Identifier((table_name, tdict['Color'])))
c.execute(sql.SQL(stmnt, (tdict['Quantity'], date)))
The insert query is giving me a TypeError
TypeError("SQL identifiers must be strings")
Can anyone please help? What am I doing wrong? How should the Identifier be made to behave as a string?
Note: I've tried to pass the Identifier elements through a str class but it didn't work. ie
stmnt = ("INSERT INTO {} (%s, Date) VALUES(%s, %s)").format(sql.Identifier((str(table_name, tdict['Color']))))
You are asking sql.Identifier() to create an identifier out of a tuple, e.g. ('small1111','magenta'). Because format() only substitutes into braces {} (and not %s), I think what you actually had in mind was this:
stmnt = sql.SQL("INSERT INTO {} ({}, Date) VALUES(%s %s)").format( sql.Identifier(table_name), sql.Identifier(tdict['Color']) )
I'd suggest you rethink your database design, though --- you should probably have columns named size, code, and color rather than separate tables and columns for each. That will prevent you from having to add a new column each time a new color or a new table for each new size or code. SELECT count(*) FROM inventory WHERE size = 'small' AND code = '1111' GROUP BY color seems preferable to having to create queries dynamically.
This error message will also appear when you have a typo error where you should have used sql.Literal('someFixedNumber'), but instead using sq.Identifier('someFixedNumber')
I have two tables. Both of them have a column named 'title'. When I use the following code snippet to join two tables, I can't access one of the title column.
$select = $this->select(Zend_Db_Table::SELECT_WITH_FROM_PART);
$select->setIntegrityCheck(false);
$select->join("service","service.id = lecture.service_id");
return $select;
is there a way to access both columns?
You need to rename one of the columns so it doesn't conflict with the other. If you pass an array as the optional 3rd argument to join(), you can specify which columns to retrieve from the joined table. If one or more of the entries in the array is hashed, then the hash key will be used as the property name. With the code below, you can refer to the title column of the service table as "service_title" in your query results. If you want other columns from the service table, add them to the array, with or without hashes as desired.
$select = $this->select(Zend_Db_Table::SELECT_WITH_FROM_PART);
$select->setIntegrityCheck(false);
$select->join("service", "service.id = lecture.service_id",
array("service_title" => "service.title");
return $select;
$select = $this->select();
$select->from(array('t'=>'table1'), array('table_title AS title_first','table_sendo_colun','table_third_colun'));
$select->setIntegrityCheck(false);
$select->join("service","service.id = t.service_id");
return $select;
Maybe It can do the job.
Regard´s.
