When I am trying to get my data from MySQL in Power bi, after some time power bi gives the following error: Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: [DataSource.Error] MySQL: Fatal error encountered during data read.. '.
Since I am working with json data type, I assume that perheps there is a problem with that, but how to solve this error?
I was looking for solution but I found only something about changing data type. So I did so but it stils gives me this error.
The error there seems to be about the data source not the data type.
We ve had few of these before, it might have to do with some edit done in the data source which i assume in an SQL database.
One solution would be to revoke PBI access and grant it again.
I wrote this sql codes in qt5 in ubuntu. I want to update a table. But I received following error:
QSqlError(1065, "QMYSQL: Unable to execute query", "Query was empty")
This is my sql code:
query4.prepare("update food_main set cost=:material_cost,"+material+"=:material_num where name='"+material_name+"'");
query4.bindValue(":material_cost",material_cost);
query4.bindValue(":material_num",material__num);
query4.exec();
I must say that my table updates every time I run my code but I have the error too. Table and columns and variables were made in right method. What should I do?
I've declared an handler which will handle SQLEXCEPTION, in the clean up code i had it do SELECT 'My Handle';, i ran a script that fails because of a primary key violation and it worked cause i got my output.
the problem with DECLARE ... HANDLE FOR SQLEXCEPTION is that when there is an error it will run though it's doesn't say what error triggered it, so i want to output the error
How do i output the SQL Error using a MySQL Query, i don't care if i can only output the error code/id i just need something to output giving me an indication on what the error is so i can fix the problem
EDIT: in case if it's not obvious, this code is in an SQL Procedure
There is nothing in the DECLARE HANDLER documentation on this functionality. You could handle the errors MySQL returns to your application and print or log them that way.
I actually haven't used any handles, but i think you can make your code into a stored procedure and then run the stored procedure!! You might find MySQL accepts what you are trying to do then.
There is a Pentaho Data Integration (Kettle) Job that I'm trying to run on a client's workstation. It yields the following error:
2012/05/21 11:38:21 - Update Case Capital.0 - ERROR (version 4.3.0-GA, build 16753 from 2012-04-18 21.39.30 by buildguy) : Unable to commit Update connection [Voyager] :org.pentaho.di.core.exception.KettleDatabaseException:
2012/05/21 11:38:21 - Update Case Capital.0 - ERROR (version 4.3.0-GA, build 16753 from 2012-04-18 21.39.30 by buildguy) : Error closing prepared statement
2012/05/21 11:38:21 - Update Case Capital.0 - ERROR (version 4.3.0-GA, build 16753 from 2012-04-18 21.39.30 by buildguy) : This statement is already closed.
The Job runs fine on my computer on a test database, and it ran without any problems at the client as well. Other Kettle Jobs also fail with the same error at the client.
The error happens in an Update step (that runs SQL UPDATE statements) after an arbitrary number of updates had been done. The database used is Firebird 2.5.1.26351 (super classic).
Any advice as to why this happens?
Given the error message Error closing prepared statement and This statement is already closed., I think you are confronted with a bug in Jaybird 2.1.6 and earlier, where closing a statement multiple times will throw an SQLException (while the JDBC api doc specifies that a close() should be ignored if already closed).
That bug is fixed in Jaybird 2.2 (which has not been released yet, but the beta is available at http://www.firebirdsql.org/en/jdbc-driver/ )
I hope you can test if that indeed solves the problem, otherwise I would appreciate a more detailed bug report at http://tracker.firebirdsql.org/browse/JDBC

I have loaded an UDF function into MySQL (without having selected any particular DB). It used to work well during my session but now I get the error "ERROR 1305 (42000): FUNCTION currentdatabase.myfunction does not exist" when I try to use the function with the following sql statement :
select myfunction('aaa');
I then tried to drop the function and I got the same error code :
mysql> drop function myfunction;
ERROR 1305 (42000): FUNCTION database.myfunction does not exist
if a DB is selected.
Another error code otherwise :
ERROR 1046 (3D000): No database selected
So I decided to specify again the function and I got the following error code :
CREATE FUNCTION myfunction RETURNS INT SONAME 'myfunction.so';
ERROR 1125 (HY000): Function 'myfunction' already exists
My question is: how to use again my function ?
Thanks in advance.
Note: there is no space problem like ("select myfunction ('aaa');") as reported on several other websites.
I recently encountered this issue my self and I put together a quick blog post about it:
When installing a UDF recently I got an
annoying error message, which didn't seem to want to go away. Deleting
the function before attempting to remove it did not work so I used the
following set of escalating commands to attempt to get it to
install. But back to the error for a moment:
bash > mysql -u user -p < installdb.sql
Enter password:
ERROR 1125 (HY000) at line 7: Function 'lib_mysqludf_ssdeep_info' already exists This can be
solved really simply with the following options:
Attempt
to delete the function and then reinstall it Delete the
function row from the mysql.func table and then reinstall it
Stop the MySQL server (after trying option 2), start it again and
then reinstall it
From my testing you do not need to have backups of your binary database files as #jmcejuela suggests in his answer.

I believe the problem comes from removing the .so library before dropping the function/s. The server still believes it has the functions since they appear in SELECT * FROM mysql.func but of course calling these functions fail. Somehow DROP doesn't simply remove entries in this table but also checks whether the libraries are found which makes this fail. CREATE supposedly just check first the func table which makes this fail...
The solution is to restore the func table (func.MYI, func.MYD, func.frm files under your mysql's data/mysql) to the point everything matches.
Luckily I had a backup of these files. Otherwise you will have to backup them from a new mysql installation (you could simply install locally a new server not to remove your current one)
Bottom line: do not remove the .so libraries before dropping the functions.
Got some of these errors when swapping out (not dropping) the .so library before dropping the function(s).
Restarting the server eliminated the error messages, whether the functions were successfully dropped or not. Mysqld just looked at the mysql.func table and loaded functions from the (new) .so. I know restarting the server is not always an option, but if it is, it's fast and complete.
