I have made a program allows a user to manipulate a database, I have a part where the user can add multiple entries into a certain database (anywhere between 1 to 10 entries) I have created another program (below) that I use to "reset" the database, using similar principles to what my main program does.
import sqlite3, time
schoolDBConn = sqlite3.connect("SCHOOL_DB.db")
schoolDBCursor = schoolDBConn.cursor()
schoolDBCursor.execute(
"""
CREATE TABLE IF NOT EXISTS USER_DETAILS
(
username text,
password text,
clearance int,
classes int
)
"""
)
schoolDBCursor.execute("SELECT * FROM USER_DETAILS")
print(schoolDBCursor.fetchall())
if input("Delete all user_details?").upper() == "Y":
schoolDBCursor.execute("DELETE FROM USER_DETAILS")
if input("add items to user_details?").upper() == "Y":
user_list = [("foo","bar",3,0),("bar","foo",3,0),("Terri","Pass",2,0),
("Chris","Pass",2,0),("Tony","Pass",2,0),("Emma","Pass",2,0),
("Thomas","Pass",1,0),("Penny","Pass",1,0),("Kamryn","Pass",1,0),
("Kelsie","Pass",1,0),("James","Pass",1,0),("Connor","Pass",1,0),
("Steve","Pass",1,0),("Bob","Pass",2,0),("Elon","Pass",1,0)]
for i in user_list:
schoolDBCursor.execute("""INSERT INTO USER_DETAILS VALUES (?,?,?,?)""",
(i[0],i[1],i[2],i[3]))
schoolDBCursor.execute("SELECT * FROM USER_DETAILS")
print(schoolDBCursor.fetchall())
If I run this function, all the items in the existing database are printed, then if I choose to only delete what exists in the database, the print function returns nothing. If I choose to delete and then "add" the items to the database, the print function returns the items I added
However, when I re-run the program, the first print statement returns the original items in the database (not the deleted table, or the items in the users_list) and this is of course not helpful.
My main program is affected by this too, and it causes problems as I need data to be updated quickly.
I also use an application "SQlite manager" to view my tables, and they do not update in that either
Turns out I did not commit the data, I had to do:
schoolDBConn.commit()
or
with schoolDBConn:

When creating a flask site with sqlite3, I noticed that if I tried to INSERTINTO (using a web-form) the database, when the database was empty, it wouldn't produce an error, but nothing would happen, the INSERT INTO (SQL) would simply not take effect.
I had to manually populate the database using a pre-made query, and then, without changing anything else in the code, the inserting-into the form worked fine.
Can anyone shed any light as to why this might have happened? I assume it isn't necessary for a database to be populated in order for it to be used/functional in flask/sqlite3.
I wondered if it had anything to do with my setup.
create-db.py
import sqlite3
db_locale='users.db' #flask will create this db if it doesn't exist
connie=sqlite3.connect(db_locale)
c=connie.cursor() #used to create commands
c.execute("""
CREATE TABLE comments
(
id INTEGER PRIMARY KEY AUTOINCREMENT,
title TEXT,
name TEXT,
comments TEXT
)
""")
connie.commit()
connie.close()
The addcomment() and insertcomment() methods in the main .py file
def addcomment():
if request.method=="GET":
return render_template('addcomment.html')
else:
user_details=(
request.form['title'],
request.form['name'],
request.form['comments']
)
insertcomment(user_details)
return render_template('addsuccess.html')
def insertcomment(user_details):
connie=sqlite3.connect(db_locale)
c=connie.cursor()
sql_execute_string='INSERT INTO comments (title,name,comments) VALUES (?,?,?)';
c.execute(sql_execute_string,user_details)
connie.commit()
connie.close()
print(user_details)
I am creating a database in Microsoft Access 2010 where when a user logged in the database, the user will only see records that is related to him or her. I've put a criteria in the record's query specifically in IssuingManager field which is [Forms]![frm_Home]![txtUser] but I always get enter parameter value when I run it. txtUser is an invisible text box in my main form so the records will have a reference on which records to filter. My main goal is to limit the user's data to their own records and hide or block them to others. I am new to access and still learning it. Any help or other ways I can filter the data or limit it to the records that is only related to the current user logged in is a big help.
This is my SQL code:

I would recommend to avoid using form's field references in queries at all. If form closed, the query will request parameter, like most likely in your case.
Replace the reference by global function created in standard module. This function can store the name, for instance, in static/global variable or retrieve it from table. Main or login form can set this variable/table record once, then the form can be closed without affecting queries functionality
Add another column and put the username. So when selecting the records, there's a condition where user='username'. They look all the data base on what the username has.
your method is fine & correct; you just have some sort of cockpit implementation error
the criteria in the query should be: Forms!frm_Home.txtUser
you could have a spelling error in your form name or text box name
make the textbox visible and enter a valid entry and run the query manually
what you are getting appears to be a parameter prompt that means it cannot find the object i.e. form named frm_Home
maybe someone once wrote a script for mass change of lotus type groups? Mass but not all, only grups with first two characters begins on ('GD') i need change mostly type from mail only (3) to Multipurpose (0).
Just select the groups, create an agent with this code, that runs on selected documents:
FIELD GroupType := "0";
If you really want to do the selection in your agent, then let it run on "all documents in view" and add a selection before the action:
SELECT #Begins( ListName ; "GD" );
FIELD GroupType := "0";
As this will run a lot slower I would manually select the groups and use the first agent as selecting is as easy as setting the cursor to the first group with "GD", then scroll down to the last one and click it while holding the Shift- Key.
According to the Peoplebook here, CreateRowset function has the parameters {FIELD.fieldname, RECORD.recname} which is used to specify the related display record.
I had tried to use it like the following (just for example):
&rs1 = CreateRowset(Record.User, Field.UserId, Record.UserName);
&rs1.Fill();
For &k = 1 To &rs1.ActiveRowCount
MessageBox(0, "", 999999, 99999, &rs1(&k).UserName.Name.Value);
End-for;
(Record.User contains only UserId(key), Password.
Record.UserName contains UserId(key), Name.)
I cannot get the Value of UserName.Name, do I misunderstand the usage of this parameter?
Fill is the problem. From the doco:
Note: Fill reads only the primary database record. It does not read
any related records, nor any subordinate rowset records.
Having said that, it is the only way I know to bulk-populate a standalone rowset from the database, so I can't easily see a use for the field in the rowset.
Simplest solution is just to create a view, but that gets old very soon if you have to do it a lot. Alternative is to just loop through the rowset yourself loading the related fields. Something like:
For &k = 1 To &rs1.ActiveRowCount
&rs1(&k).UserName.UserId.value = &rs1(&k).User.UserId.value;
&rs1(&k).UserName.SelectByKey();
End-for;
We have a weekly backup process which exports our production Google Appengine Datastore onto Google Cloud Storage, and then into Google BigQuery. Each week, we create a new dataset named like YYYY_MM_DD that contains a copy of the production tables on that day. Over time, we have collected many datasets, like 2014_05_10, 2014_05_17, etc. I want to create a data set Latest_Production_Data that contains a view for each of the tables in the most recent YYYY_MM_DD dataset. This will make it easier for downstream reports to write their query once and always retrieve the most recent data.
To do this, I have code that gets the most recent dataset and the names of all the tables that dataset contains from the BigQuery API. Then, for each of these tables, I fire a tables.insert call to create a view that is a SELECT * from the table I am looking to create a reference to.
This fails for tables that contain a RECORD field, from what looks to be a pretty benign column-naming rule.
For example, I have this table:
For which I issue this API call:
{
'tableReference': {
'projectId': 'redacted',
'tableId': u'AccountDeletionRequest',
'datasetId': 'Latest_Production_Data'
}
'view': {
'query': u'SELECT * FROM [2014_05_17.AccountDeletionRequest]'
},
}
This results in the following error:
HttpError: https://www.googleapis.com/bigquery/v2/projects//datasets/Latest_Production_Data/tables?alt=json returned "Invalid field name "__key__.namespace". Fields must contain only letters, numbers, and underscores, start with a letter or underscore, and be at most 128 characters long.">
When I execute this query in the BigQuery web console, the columns are renamed to translate the . to an _. I kind of expected the same thing to happen when I issued the create view API call.
Is there an easy way I can programmatically create a view for each of the tables in my dataset, regardless of their underlying schema? The problem I'm encountering now is for record columns, but another problem I anticipate is for tables that have repeated fields. Is there some magic alternative to SELECT * that will take care of all these intricacies for me?
Another idea I had was doing a table copy, but I would prefer not to duplicate the data if I can at all avoid it.
Here is the workaround code I wrote to dynamically generate a SELECT statement for each of the tables:
def get_leaf_column_selectors(dataset, table):
schema = table_service.get(
projectId=BQ_PROJECT_ID,
datasetId=dataset,
tableId=table
).execute()['schema']
return ",\n".join([
_get_leaf_selectors("", top_field)
for top_field in schema["fields"]
])
def _get_leaf_selectors(prefix, field):
if prefix:
format = prefix + ".%s"
else:
format = "%s"
if 'fields' not in field:
# Base case
actual_name = format % field["name"]
safe_name = actual_name.replace(".", "_")
return "%s as %s" % (actual_name, safe_name)
else:
# Recursive case
return ",\n".join([
_get_leaf_selectors(format % field["name"], sub_field)
for sub_field in field["fields"]
])
We had a bug where you needed to need to select out the individual fields in the view and use an 'as' to rename the fields to something legal (i.e they don't have '.' in the name).
The bug is now fixed, so you shouldn't see this issue any more. Please ping this thread or start a new question if you see it again.
