Can not edit parameter in Read Database in RapidMiner 7 - rapidminer

I drag a Read Database operator in the process view and then try to edit the parameter, but the parameter can not be edited as showing (btw, I already added a database connection in manage database connections):
Not sure how to solve the problem?

It looks like your view setup got a bit out of order. Try to click the little blue arrow on top of the Parameters tab, or even reset the complete view via RapidMiner's menu -> View -> Restore Default View.

Server returns invalid timezone. Go to Advanced tab and set servertimezone property manually

My Intelij IDE wont connect to my database server of MySQL Workbench, it specifies it as a timezone problem and wants me to go to advanced tab and set serverTimezone property manually.
I tried looking if there where a similar problem but i cant seem to find it.
In the Database tool window, right click on the data source, choose Properties (Shift+Enter), click on the Advanced tab.
Set the serverTimezone property to UTC.
See also the corresponding documentation page.
#CrazyCoder is correct but here is a more details answer:
In DataGrip right click on your database drop down menu click on Properties then go to Advanced and slowly look for severTimeZone as in this attachement below:
Don't forget to click on apply and test again it should work.
Done.
I had same problem. Running
SET GLOBAL time_zone = '+8:00';
on MySql command line solved the problem!
You need to set 'serverTimezone' with 'UTC'. But use upper case!
Open Properties, in mac use (Command + ;), click on the Advanced tab.
You can follow the picture find the configuration , Set Time zone = UTC

Why won't mysql workbench allow me to execute or create a schema?

I wanna create a schema because I wanna test out tables. I tried to click the "create a new schema", button at the top but it was glazed over where if I click it, nothing happens as if it isn't even there. So after this, I thought "Well I'll try and execute a schema via a statement until then I realized that the execute button is also glazed over. I'm wondering if there's something wrong and obvious I did since I just installed MySQL and have done nothing else in the settings.
You can right-click and create the schema from MySQLWorkbench. The steps are below:
List of Schemas in UI
Right-click, and select Create Schema
Specify the name of the schema to be created
Click Apply, confirm the SQL script in the dialog box, and again click Apply
Note the successful execution of the script
Verify the new schema in the Schemas section in UI

Unable to resolve valid table in PhpStorm

I'm getting unable to resolve table errors appear in php files containing SQL querying valid tables.
If I Ctrl + Enter over the query, then I get expected results in the DB console, and if I expand the database in the DB explorer tab then I can see the tables.
It's not affecting code execution, but it's annoying because it catches my eye when writing code, and it masks real SQL errors.
I've tried refreshing the database connection, and I've verified that the php tab is connecting to the correct database.
In 2017.2 I had to go to
Settings > Languages & Frameworks > SQL Resolution Scopes
and add my project and database link in there to get it right again.
Try re-creating DB connection from scratch (delete existing one and create it again).
Thinking of possible reasons ... I can think of this scenario:
working with project in current stable version (currently 2016.1.x);
trying EAP build for next version (2016.2 at this moment) on this project and make some DB-related changes there (even simple syncing DB);
going back to stable version (2016.1.x) .. and because new version uses newer file format/versioning for DB-related data (cached DB structure etc) IDE may start ignoring "unknown/newer" format for such data and instead of throwing appropriate warning it just "silently" throwing "unresolved table" message.
No other ideas.
I was getting what OP was getting, and the problem was my DB Server was MariaDB and i had MySQL selected as the SQL Dialect.
See File > Settings: Languages & Frameworks > SQL Dialects.
Faulty error pollution DRIVES ME NUTS TOO!
If I start having SQL resolution issues, I will check my resolution scopes (settings -> Languages & Frameworks -> SQL Resolution Scopes).
Generally I have the most issues when my project mapping is set to 'All Data Sources' by default.
The following steps always fixes it for me:
Click the Project Mapping Dropdown
Uncheck the global 'All Data Sources' setting (required to make other selection available)
Click the drop down arrow for your Database connection
Check 'All Schemas' (Or Specific Tables)
Click OK to close the settings window
Your false resolution errors should disappear after the next parse cycle.
You aren't limited to applying the above steps to just one DB connection, you can do it for all connections in your project.
Sometimes adding a custom resolution scope will work as well, but it is hit or miss for me.
Click the plus sign (top right)
Select the file you are working on and hit 'OK'
Select the 'Resolution Scope' column
Deselect 'all data sources'
Select the specific DB resources you want
Reconnecting to the DB never works for me.
Specifying the table works well... but it can become very cumbersome as the project grows.
I have also run into an additional situation where PHPStorm would only resolve some of my queries, no matter what scope resolution settings I used. However, after I attached a console to my file, they resolved just fine.
(Search for 'Attach Console' in Help | Find Action. You can also add it to a 'Quick List' or Keymap it.)
Although this answer is specifically for phpstorm, I had this same issue in IntelliJ and none of the above fixes worked for me. I had my scope added, everything was active. I could query the database in the console window perfectly fine, and I was totally stumped.
Eventually, I noticed some text in the database panel that said 0 of 4 in tiny text. It looked like this:
Upon clicking on the 0 of 4 text, I discovered there were no schemas added to the connection, even though a default database was set upon making the connection originally. Going to that page allows you to add schemas. Be sure to either select "All schemas", "Current schema", or the specific database that you want to use with your connection.
Changed dialect to MariaDB on global and project level.
OR
To dismiss this error in PHPStorm versions before 2017 which have no SQL Resolution Scopes option:
Go to File
Go to Settings...
Go to Editor and then Inspections
In SQL chapter uncheck Unresolved reference
Click Apply and then OK
Adding database name before the table name worked in my case.
For instance, instead of writing SELECT * FROM Client, put SELECT * FROM database.Client.
I will add another answer, because for me, it was a completely different (embarrassing) cause:
I somehow forgot to add the database name in the data sources general settings (where you also set the host, user and password).
In my case, I have clicked the right button in the SQLScript and change the Dialect to "Generic SQL". It worked for me.
I solved this problem as follows:
CTRL + SHIFT + F10
new query console
Write a selection query to the database, for example:
SELECT * FROM user WHERE user_email='$email' AND user_password='$password'
Enter your code page and click on the table name in the query
ALT + ENTER
run query in console
Select the console you created
First, you need to check the Schemas tab, and make sure you've added the database.
If the unable to resolve table error stills appears, there're two options to fix this:
1.You can edit the properties of the Data Source and add the name of Database, then you can see that select * from table works well.
2.On the other hand, you can also use sql like this select * from database.table. It works for me.
By the way, in many situations, autocomplete can be very useful.
[PHPSTORM]I solved this problem by setting
Languages&Features
SQL Dialect
adding your current file into path and modify its SQL Dialect as a server you are using.
NOTICE!!!!! mine is MySQL but it is exactly MySQL causing problems, after switching into [generic SQL] PROBLEM SOLVED!!!

SSRS Dataset Field Refresh not updating for Tablix

I have updated the SP for the attached dataset that the tablix is using. The refresh worked fine and I can see my new fields in the shared data set when I look in the Fields tab. My problem is the tablix itself is not giving me access to the new fields. There is a disconnect somewhere and I cannot figure out hot to get the tablix to see the updated fields available in the dataset. I run into this problem frequently and hope I can get a good answer here to return to in the future as I am sure I will need to. I have googled and looked through the suggested questions here and I cannot find one that is directly related to this issue.
I will also know note that the report project is in TFS source control as I read that has some adverse side affects. I have marked the whole project for edit and also went to the folder structure and made sure everything was unset to read only.
I am using SSRS 2008 in VS 2010.
Just found it... I don't understand the need for hidden menus like this..
Click the report itself, then go up to View on the menu and at the very bottom there is "Report Data". From here you can select your dataset and go to its properties and refresh the reports attached dataset's fields. What a pain in the butt.
Here is a link that helps better explain it.
http://blog.dontpaniclabs.com/post/2012/01/26/Developings-Reports-for-SQL-Server-Reporting-Services
You can also delete the .data file if you still can't get it to refresh.
Go into the file folder where the .rdl file exists
Next to it, there should be a file with the same name with the
.rdl.data extensions. Delete this file.
It appears to force the refresh probably because it has to recreate the file.
Here's a less invasive way but may not always work:
In the Report Data windown, right click on you dataset and click
Dataset Properties like so:
Click Refresh Fields near the bottom right of the Dataset Properties
window:
After changing the Stored Procedure code, without changing the name and number of fields returned, I could only get the report to seemingly call the new format of the stored procedure by clicking the Refresh button in the report's Preview tab.
Go into your solution folder, where the rdl's are stored and delete .rdl.data file for your report.
Next time you'll run the report, new rdl.data file will be created and it will have all the new fields from the updated SP.
ok, this maybe an older thread, but I kept running into the same problem on occasion. The absolutely easiest way to fix this is adding the following line of code to the beginning of the stored procedure that produces your dataset for the report:
SET FMTONLY OFF;
Happy coding :)
I ran into a very similar issue:
Added a new field to an existing SQL table function
(With some difficulty) added the new field to the existing dataset in SSRS
Spent some time unsuccessfully trying to add the new fields to the table (tablix?) in design mode.
This didn't work for me so eventually I opened the particular report file [filename].rdl in a text editor and surprise surprise it was XML. It was easy enough to add the missing field manually, and visual studio then prompted me to refresh the report.
<DataSets>
<DataSet Name="DataSet1">
...
<Fields>
<!-- add new field at this level -->
<Field Name="[newfield]">
<DataField>Email</DataField>
<rd:TypeName>System.String</rd:TypeName>
</Field>
</Fields>
</DataSet>
</DataSets>
I am having exact same issue in VS 2012. The stored procedure used as a query will not allow to refresh fields. When the button is pressed nothing happens.
The only solution I found is to flip the Query Type to Text and provide the parameter values on the exec call to the SP.
Why do we have to put up with these obvious show stopper bugs?
Had the same issue and I was able to resolve it by renaming my dataset in properties, creating a new dataset with the original name, and then hitting the refresh button.
Old thread, but I ran into this using VS 2015 and SSMS 2016. I was certain it was an issue with VS. When I went back to SSMS and tried executing my stored procedure, however, I found that passing certain parameter values would cause the query to fail. Interestingly, I was able to ALTER the stored procedure without encountering any errors. (Perhaps because some combinations of parameters wouldn't result in a failure?)
Anyways, at the end of the day it was faulty coding in my sproc that was causing the fields in SSRS not to refresh. When I went back and corrected the issues with my code, everything worked as expected in VS.
I am working in Visual Studio 2015 and none of the above answers worked for me. If you are getting the data from a stored procedure, you need to open the .xsd file and right click on the data model. Select Configure, and the correct values from the procedure should appear on the right of the window.
Then refresh your dataset from the Report Data tab.
I had the same issue.
I installed SP1 so that .rdl.data file would get generated which inturn also fixed the data refresh issue.

I was trying to use an ODBC driver for the datasource that connected ok, but wouldn't show Fields in VS 2015 SSRS report. I went back and used a datasource based on SQL Server driver (it's in the choices when designing a datasource) and it worked perfectly.
I had this same issue but the cause was different from the other answers at the time of this writing.
In my case, the stored procedure used as the data source was returning multiple data sets (due to some debugging code that I had left in there).
SSRS was "seeing" the fields in the first dataset, whereas I was expecting it to see the fields in the second dataset.
Removing the extraneous datasets fixed the issue and SSRS was able to see the fields that I intended.
Clearing reportviewer's datasources works for me.
this.(reportviewername).LocalReport.DataSources.Clear();
Open the Visual Studio 2008 reports solution
Open (double click) your report (.rpt file) on left pane
Press Ctrl + Alt + D to open the Report Data panel
Expand the DataSets folder
Find the report's main data set and right click the "DataSet Properties" menu
Click the "Refresh Fields" button on the popup window.
Deleting .data no work for me. Deleting Dataset and adding again worked. And I had previously configured VS/SSRS to NOT cache.
refresh and deleting .data did not work for me. So I just manually added the fields.

Retrieve Schema for MySQL DB-Connection does not work in Talend

I've created a new MySQL DB Connection, and verified it's OK by pressing the Check button in DataBase Connection - Step 2/2 form.
Then I right-click on the DataBase Connection I created and select Retrieve Schemas.
On the first screen of the Schema form that is opened I leave all default values and press Next.
On the second page the Next button is greyed-out, and no matter what I select/fill on the form it remains being greyed out.
Anybody knows why it may be so?
Thanks!!!
I had the same problem, but you can avoid it.
If you select the CATALOG, the Next button will still be greyed as on attached screenshot. But if yo will expand the CATALOG and Sellect All, the Next button will be active.
I had this same issue, in order to resolve it I needed to generate database diagrams and then verify that talend could see all the tables I was looking to retrieve. Basically if you cannot expand any schemas it means there is nothing to import.
