I have downloaded the xml containing the entry tease out along with all its templates and modules from the link https://en.wiktionary.org/w/index.php?title=Special:Export&pages=tease_out&templates.
Clearly, this xml contains module en-headword.
Then I import this xml with
php C:\Bitnami\mediawiki-1.35.2-0\apps\mediawiki\htdocs\maintenance\importDump.php C:/Users/Akira/Desktop/tease_out.xml
php C:\Bitnami\mediawiki-1.35.2-0\apps\mediawiki\htdocs\maintenance\rebuildrecentchanges.php
php C:\Bitnami\mediawiki-1.35.2-0\apps\mediawiki\htdocs\maintenance\initSiteStats.php
Then it shows on my cmd that
C:\Users\Akira>php C:\Bitnami\mediawiki-1.35.2-0\apps\mediawiki\htdocs\maintenance\importDump.php C:/Users/Akira/Desktop/tease_out.xml
Done!
You might want to run rebuildrecentchanges.php to regenerate RecentChanges,
and initSiteStats.php to update page and revision counts

Could you please explain why the content is not rendered properly?
I am the superuser of a particular database schema. Therefore I have all privileges on the tables in this schema, including ALTER DELETE UPDATE and INSERT.
I am administrating this database using the GUI MySQL Workbench 6.3. I used to select rows and to obtain a read-only result grid, which was convenient because it prevented me from accidentally editing data in my table.
This was indicated by a 'read only' flag in the bottom right corner of the result grid (see below).
However, I did not change anything in the structure of the table, and now when I select rows I am able to edit data and the 'read only' flag has disappeared.
I find it a bit unsecure because it would mean I could accidentally edit data in the table by mistyping.
How could I revert to a read-only result display?
The rules that allow editing a result set are very strict. The select query must be a plain one - no aggregate functions, no joins, no unions. There must be a primary key which is used to address the records to be changed.
Update: it wasn't necessary to worry about accidentally editing records in the table while not being in read-only mode.
Indeed, if you change a record in the table (in the screenshot below, I changed a year from 2010 to 2020), for this change to be actually committed in the database, you would need to click the "apply" button in the bottom right corner.
Moreover, upon closing the tab, you are asked whether or not you want to save changes. Consequently, if you accidentally edited a record, you just have to click "Don't save" upon closing the tab.
I have a python app that has an admin dashboard.
There I have a button called "Update DB".
(The app uses MySQL and SQLAlchemy)
Once it's clicked it makes an API call and gets a list of data and writes that to the DB, and if there are new records returned by the API call it adds them and does not duplicate currently existing records.
However if API call returns less items, it does not delete them.
Since I don't even have a "starting to google" point I need some guidance of what type of SQL query should my app be making.
Like once button is clicked ,it needs to go through all the rows:
do the changes to the updated records that existed
add new ones if there are any returned by the API call
delete ones that API call did not return.
What is this operation called or how can I accomplish this in mysql?
Once I find out about this I'll see how can I do that in SQLAlchemy.
You may want to set a timestamp column to the time of latest action on the table and have a background thread remove old rows as another action. I don't know of any atomic action that may perform the desired data reformation. Another option might be satisfactory is to write the replacement batch to a staging table, rename both versions (swap) and drop the old table. HTH
I am using the MySQL for Excel add-in. I have been using this for months to highlight a set of data and load it into my database.
I added a new table last week, and was successfully loading data into it using the same method. It stopped working. When I attempt to Append data, I get an error dialogue box that says "Cannot Find Column 30"...which happens to be the number (and therefore) last column in my table.
Some more information:
- If I highlight this same set of data and try to write it to another table, it will allow me to (even though I don't confirm and do it). I get past the error dialogue box to the Mapping dialogue box.
- I tried writing data from the previous table to this new problem table. I got the same error dialogue box.
This tells me that the problem is not with the data set. It is with the table.
I then deleted the table, all the connections and redid it from scratch. Still the same problem.
Where is this failing? Thank you.
ya even i had the same problem, even i tried the same way u did, like deleted the table recreated everything, it did not work, finally i tried to append some random table and went to "Advanced Options" at the bottom of the append pop up
in this u will see some "Stored Column mappings" and some mappings in it, now delete all of them and hit "Accept" now u can append the table
it will work
I know this is super old but I have a solution because it just happened to me.
Try append on different table. When box pops up click 'Advanced Options'
Then under column mapping uncheck both:
(Automatically store the column mapping for the given table) AND
(Reload stored column mapping for the select table automatically)
Then goto the Stored mappings tab and delete all the stored mappings
Click Accept and then rejoice you are free of that error for life.
best -J
If Excel does not show you the "Stored Column mappings" then connect to a MySQL table not used before in Excel, then retry the Append, the mapping will be shown. Then you can follow the answer provided by user3611272.
Problem will be resolved by doing below steps:
Select any table from Table other than your target table.
Click on Append Data
Press "Advanced Options"
Select tab "Stored Mappings"
Delete your target table mapping and Accept.
it will solve the issue.
I have a ssis project with 3 ssis packages, one is a parent package which calls the other 2 packages based on some condition. In the parent package I have a foreach loop container which will read multiple .csv files from a location and based on the file name one of the two child packages will be executed and the data is uploaded into the tables present in MS SQL Server 2008. Since multiple files are read, if any of the file generates an error in the the child packages, I have to log the details of error (like the filename, error message, row number etc) in a custom database table, delete all the records that got uploaded in the table and read the next file and the package should not stop for the files which are valid and doesn't generate any error when they are read.
Say if a file has 100 rows and there is a problem at row number 50, then we need to log the error details in a table, delete rows 1 to 49 which got uploaded in the database table and the package to start executing the next file.
How can I achieve this in SSIS?
You will have to set TransactionOption=*Required* on your foreach loop container and TransactionOption=*Supported* on the control flow items within it. This will allow for your transactions to be rolled back if any complications happen in your child packages. More information on 'TransactionOption' property can be found # http://msdn.microsoft.com/en-us/library/ms137690.aspx
Custom logging can be performed within the child packages by redirecting the error output of your destination to your preferred error destination. However, this redirection logging only occurs on insertion errors. So if you wish to catch errors that occur anywhere in your child package, you will have to set up an 'OnError' event handler or utilize the built-in error logging for SSIS (SSIS -> Logging..)
I suggest you try the creation of two dataflows in your loop container. The main idea here is to have a set of three tables to better and more easily handle the error situations. In the same flow you do the following:
1st dataflow:
Should read .csv file and load data to a temp table. If the file is processed with errors you simply truncate the temp table. In addition, you should also configure the flat file source output to redirect the errors to an error log table.
2nd dataflow:
On the other hand, in case of processing error-free, you need to transfer the rows from temp into the destination table. So, here, the OLEDB datasource is "temp table" and the OLEDB destination is "final table".
Don´t forget to truncate the temp table in both cases, as the next file will need an empty table.
Let's break this down a bit.
I assume that you have a data flow that processes an individual file at a time. The data flow would read the input file via a source connection, transform it and then load the data into the destination. You would basically need to implement the Error Handler flow in your transformations by choosing "Redirect Row". Details on the Error Flow are available here: https://learn.microsoft.com/en-us/sql/integration-services/data-flow/error-handling-in-data.
If you need to skip an entire file due to a bad format, you will need to implement a Precedence Constraint for failure on the file system task.
My suggestion would be to get a copy of the exam preparation book for exam 70-463 - it has great practice examples on exactly the kind of scenarios that you have run into.
We do something similar with Excel files
We have an ErrorsFound variable which is reset each time a new file is read within the for each loop.
A script component validates each row of the data and sets the ErrorsFound variable to true if an error is found, and builds up a string containing any error details.
Then - based on the ErrorsFound variable - either the data is imported or the error is recorded in a log table.
It gets a bit more tricky when the Excel files are filled in badly enough for the process not to be able to read them at all - for example when text is entered in a date, number or currency field. In this case we use the OnError Event Handler of the Data flow task to record an error in the log but won't know which row(s) caused the problem
