Connecting using IPv6

Post by NickXCT » Tue 03 Feb 2015 19:44

I'm trying to connect to a MySQL server using IPv6. I can connect to the server using the IPv4 address with dbExpress driver and I can connect to the server using the IPv6 address using the MySQL Workbench (so I know the IPv6 address works over the network). But I cannot get the dbExpress driver to work with the IPv6 address. I have the following parameters:

DriverUnit=DbxDevartMySql
DriverPackageLoader=TDBXDynalinkDriverLoader,DBXCommonDriver200.bpl
MetaDataPackageLoader=TDBXDevartMySqlMetaDataCommandFactory,DbxDevartMySqlDriver200.bpl
ProductName=DevartMySQL
GetDriverFunc=getSQLDriverMySQLDirect
LibraryName=dbexpmda40.dll
VendorLib=not used
MaxBlobSize=-1
FetchAll=True
EnableBoolean=False
UseUnicode=True
HostName=xxxx:xxxx:xxxx:x:xxxx:xxxx:xxxx:xxxx
DataBase=databasename
User_Name=loginid
Password=loginpw
IPVersion=IPv6

Where xxxx:xxxx:xxxx:x:xxxx:xxxx:xxxx:xxxx is the IPv6 address.

Can you tell me what I'm doing wrong?

Thank you for the information. We have reproduced and fixed the issue. The fix will be included in the next dbExpress Driver for MySQL build.

That's great.

Can you tell me where the problem lies? E.g. can I work round this by not using the BuiltIn module?

To solve the problem, you can delete the "coIPVersion = 109" constant declaration in the dbxmda.pas module.
