I tried 10 different npgsql version and entity framework using visual studio 2017 to get connected to PostgreSQL database but every time I get this error:
Could not load file or assembly "System.ValueTuple,version=4.0.3.0
Even if I install this, I still get the same error. Any idea?

I have installed MySQL server, workbench, shell and connector/NET on my computer. I want to add following reference: MySQL.data in visual studio community 2019. I searched in assembles section for mysql.data but nothing is visible in search result.
I am using the following statement to connect to SQL database.
using namespace MySql::Data::MySqlClient;
My project can't finish build process because I constantly have this error during Visual Studio build: Cannot open include file: 'msoledbsql.h': No such file or directory
I have 'msoledbsql.h' file included in one of the header files.
Does anyone know the solution of this issue?
After a long research of this issue I found that I've missing msoledbsql.h file on my machine.
The solution for this is to install Microsoft OLE DB Driver for SQL Server. We can find the driver on official Microsoft site Microsoft OLD DB Driver for SQL Server and choose the one suitable for your system architecture (x64 or x86).
Very important thing during the installation process is to select both options
OLE DB Driver 19 for SQL Server
OLE DB Driver 19 for SQL Server SDK
That should solve the issue.
I have created an Oracle virtual box VM using Windows server 2012 R2 standard OS. Then I installed active directory services using sever manager feature and then I installed SQL server 2012 express edition and installed all prerequisites for SharePoint server 2013. All prerequisites are installed successfully. All the installation done on a single machine. But still I am getting an error while installing SharePoint 2013.
Setup is unable to proceed due to the following error:
Windows server App-fabric is not correctly configured.You should uninstall Windows Server App-fabric and reinstall it using the SharePoint Product Preparation tool.
The sharepoint install disk has an executable named something like prerequisite.exe. Beware though you need to do your install with SharePoint 2013 SP1. SP1 being the key.
I'm a newbie at c++ linking and databases, so may be i'm asking a really stupid question. Anyway, i'm trying to access to firebird database using Qt5 for Windows. I've checked google and found 2 ways of doing so:
build ibase driver from Qt source;
use firebird through ODBC driver.
Software versions
I'm using latest version of Qt: 5.1.1. Firebird 2.5 is working ok: i've create a test_base and test user admin. Administartion of test_base i've done through FlameRobin.
Building
I've downloaded qt5.1.1 source and unpacked it in c:/devtools/qt5.1.1-src. Since Qt4.7-4.8 folder and project structure has been changed so old FAQs cannot be applied here. So i tried to build sql.pro from qtbase\src\sql folder with 2 lines added:
INCLUDEPATH+= C:/devtools/firebird/firebird_2_5/include
LIBS+= C:/devtools/firebird/firebird_2_5/lib/fbclient_ms.lib
And i've added C:/devtools/firebird/firebird_2_5/lib/ and C:/devtools/firebird/firebird_2_5/include in system PATH. Compilation is done without any error and i get a qt_pch.h.gch\c++ file in build dir. And i have no idea what's to do next, because i hoped to have bunch of .a and .dll files or bunch of error at least.
Using ODBC driver
I've downloaded and installed firebird ODBC driver from here. Installation was successful and i created ODBC DSN source mydb in Windows ODBC manager. Test connection button from ODBC configurator says that everything is ok.
Next thing i did was opening SQL Browser example from Qt Creator. And it fails to open my ODBC base with following parameters:
Driver: QODBC
Database Name: mydb
Username: admin
Password: admin
Hostname: localhost
Port: Default
And i get an error message: "[ODBC Firebird Driver] Unable to connect to data source: library 'C:\devtools\Firebird\Firebird_2_5\bin\fbclient.dll' failed to load QODBC3: Unable to connect".
I'm looking for resolving any of this two issues. Thanks in advance.
upd: i've connected firebird database through ODBC: the error was in using x64 database with x86 QODBC. Nota bene: in order to manage x86 DSN ODBC in x64 Windows 7 one must run ODBC manager from %WINDIR%\SysWOW64\odbcad32.exe NOT from Administration Panel as it explained here.
But what about building ibase from qt source?
I have started wso2 4.0.3 in my local and tested It is working fine.
But same version I have installed in linux box,server not started it is showing below error. I used this command to start: nohup sh wso2server.sh
ERROR - DatabaseUtil Database Error - Table "UM_DIALECT" not found;
SQL statement:
SELECT COUNT(UM_ID) FROM UM_DIALECT WHERE UM_TENANT_ID=? [42102-140]
org.h2.jdbc.JdbcSQLException: Table "UM_DIALECT" not found; SQL statement:
SELECT COUNT(UM_ID) FROM UM_DIALECT WHERE UM_TENANT_ID=? [42102-140]
It should be working fine if you are using fresh binary pack (zip). Are you using different type of database other than H2? (H2 is the default database shipped with the binary pack)
if you are getting this error again, please start sever with -Dsetup option.
Ex : wso2server.sh -Dsetup
Thanks,
Chamara Silva
It happen because your WSO2 ESB is missing previous data from the previous database.
You can find your carbon database in
$wso2dir\repository\database\WSO2CARBON_DB.h2.db
Maybe there are files that missing or can't be copied to your linux environment (not only your carbon database but also other configuration files). Based on #ChamaraS's answer, i also suggest you to using fresh binary pack or create a backup pack with your custom configuration.
ps: i am just curious if you used Filezilla to transfer those files (face same problem here)
