Can't connect to MariaDB via MATLAB - Invalid MEX File - mysql

I am trying to connect to MariaDB using mYm (Mysql wrapper for MATLAB) on MATLAB.
Every time I use mYm to access DB I get an error
Invalid MEX-file 'path\to\DB\MySQL\mYm1.36 64-bit\mym.mexw64': A dynamic link library (DLL) initialization routine failed.
So far what I've understood is that DLL in question i.e. libmysql.dll is not registered.I tried do do that using regsvr32 "path\to\DB\MySQL\mYm1.36 64-bit\libmysql.dll". But that results in following error:
The module path\to\DB\MySQL\mYm1.36 64-bit\libmysql.dll failed to load.
Make sure the binary is stored at specified path or debug it to check for problems with binary or dependent .DLL files.
The specified module could not be found.
I require a solution to fix this error.
I might be wrong in assuming the dll is not registered.

DAML Sand box error: Error: Registry key 'Software\JavaSoft\Java Runtime Environment'\CurrentVersion' has value '1.8', but '1.7' is required

Getting below error when I start sandbox. I think we need use jdk8 as per the DAML doc.
daml sandbox --scenario Main:setup .daml/dist/quickstart-0.0.1.dar
Error: Registry key 'Software\JavaSoft\Java Runtime Environment'\CurrentVersion'
has value '1.8', but '1.7' is required.
Error: could not find java.dll

During my initial setup, I have faced the similar issue. It may be because of an existing Java installation in your machine.
You can try the below options to fix this issue.
Option 1:
1. Check if you have more than one version of JAVA in machine.
2. If yes, uninstall everything and do the clean installation. Make sure your Environment Path variable(s) are got set properly.
or
Option 2:
1) Download the latest JDK in Zip format "jdk-12.0.2_windows-x64_bin.zip"
2) Extract it manually in your local drive.
3) Manually update your Environment Path variables (ref. https://javatutorial.net/set-java-home-windows-10).
I hope it will help you to fix your problem.
Cheers,

Can't import file on Neo4j with RuntimeException error

I have updated the neo4j.conf file but can't seem to get rid of this error after changing the file and restarting. I am just trying to load a json file through neo4j and have included the line apoc.import.file.enabled=true on the neo4j.conf but doesn't seem to be working for me, I'm still getting the error message:
Failed to invoke procedure 'apoc.load.json' Caused by
java.lang.RuntimeException : Import from files not enabled, please set
apoc.import.file.enabled=true in your neo4j.conf
I am using neo4jCE 3.2.3 and have used the right file path for the json file as it previously worked on my desktop computer (I'm just trying to replicate it on my laptop) and I am using apoc 3.2.0.4 version plugin. The procedure apoc.load.json is also there when I call all procedures directory.

[FireDac][Phys][MySQL]-1101. Unsupported MySQL version [0]. Supported are client and server from v 3.20 to v6.2

Does anyone know how to solve this Error on RAD Studio XE6 Delphi
If you take the sample app supplied by Embarcadero
FireDAC\Samples\Comp Layer\TFDConnection\DLL_Sharing and change the FDConnection to use a MySQL server instead, you get this error.
[FireDac][Phys][MySQL]-1101. Unsupported MySQL version [0]. Supported are client and server from v 3.20 to v6.2.
The connection in the exe works, using the MySQL server, but the sharing in the DLL does not.
Even though the steps in the FireDAC DLL_Sharing are followed..
Copy the file FireDAC.Phys.MySQLWrapper.pas (from source\data\firedac directory) to your project directory, edit the file, and look for the following three lines:
if (FVersion < mvMySQL032000) or (FVersion >= mvMySQL060200) then
FDException(OwningObj, [S_FD_LPhys, S_FD_MySQLId], er_FD_MySQLBadVersion,
[FVersion]);
Remove them (or place them in comments), and rebuild your project. Make sure that it uses the FireDAC.Phys.MySQLWrapper from your project directory (you may have to close and re-open the project to ensure it uses your local unit).
That way, you still won't be able to connect at design-time, but at least it will work at runtime.

Use the "original" mysql libmysql.dll and its work fine ;)
the mariadb's libmysql.dll causes this error

Unable to schedule an ssis package WHICH RETRIEVES data from MYSQL

I've created an SSIS PACKAGE on machine X to retrieve data from MYSQL DB Query from machine Y and write to an SQLSERVER Destination Table which is on machine Z(compulsions since I am unable to connect to mysql from Z and X is the only machine which has navicat).
The package runs to the T when run manually and I'm trying to schedule it on machine X for Z's DB .I've created the xml configuration file and placed it on Z since the process runs on Z's DB.and the job fails when executing as a scheduled Job.
I've added passwords to the config file as they don't save automatically.
I suppose it's due to different machines being used(Package on X running on Z's DB and config file on Z).
Here's the error:
Failed to open package file "D:\CSMS\SSIS\Random\Random\MySQlDBtoDWH11DataTransfer.dtsx" due to error 0x80070015 "The device is not ready." This happens when loading a package and the file cannot be opened or loaded correctly into the XML document. This can be the result of either providing an incorrect file name was specified when calling LoadPackage or the XML file was specified and has an incorrect format.

Unable to understand where I'm failing!
Are you using Direct configuration or using Indirect( in which your xml config file path is saved in Environmental variable?
IF you are using Direct configuration, you need to make sure your both machines have the same folder structure which is saved in package.
If you are using Environment variable to point to configuration file. Make sure you have changed the value of variable according to machines and folders where your configuration file is.
To close this question,I've scheduled it to run from a batch file and the process is running fine.

xcode: Mysql connector library not work on iphone5 (armv7s) ,any solution?

I built my App using Mysql Connector/C to connect a remote Mysql database, its works fine on the simulator (no errors, no warnings) but when i try to run it on my device (iphone5) i got this error:
No architectures to compile for (ARCHS=armv7 armv7s, VALID_ARCHS=armv7 armv7s)
i tried -as in some answers- to change setting (Architectures - Build Active Architectures- Valid Architectures) but the error still, only when i change the setting (Architectures & Valid Architectures) to "armv6" its build without error but many warnings appears says:
warning: no rule to process file '(my App dir)/main.m' of type sourcecode.c.objc for architecture armv6
and also for all .m files, when i tried to start the App i got message:
Xcode cannot run using selected device
I know that the Connector library need to update , but are there any solution ?
your need compile the connector lib in xcode for iOS (armv6, armv7, armv7s, i386), then use lipo tool to combine output libs.
direct connect your mysql in app is not safe, a suggest way is setup a Apache+PHP+MySQL server, then on iPhone useing ASIHTTPRequest to connect your server.
