i am getting error "security issue : the connection string may contain a password"
i want to connect access database with my c++ program using ODBC.
i am using visual studio 2008.
following are the steps what i have done to create this
created simple access database (testdb.mdb) and added user dsn(test)
then created mfc application in database support i selected database view with file support and selected odbc and cliked button data source and selected my created dsn(test)
now when i build this that above error occurs what shoul i do ?
just remove the line
#error Security Issue: The connection string may contain a password
from the generated header file.
it is there just to make you aware of that it is not good to have hardcoded passwords in your code.

I'm trying to setup Redmine on the following products
redmine-4.0.7
Rails 5.2.4.2
Phusion Passenger 6.0.7
Apache/2.4.6
mysql Ver 14.14
I expected there will be initializing page however, I got `Internal Error' from http://mydomain/redmine/
I can see the following messages in log/prduction.log
Completed 500 Internal Server Error in 21ms (ActiveRecord: 1.5ms)
ActiveRecord::StatementInvalid (Mysql2::Error: Can't find file: './redmine/settings.frm' (errno: 13 - Permission denied): SHOW FULL FIELDS FROM `settings`):
It seems I need ./redmine/settings.frm but there isn't.
Does anyone know how to place ./redmine/settings.frm and what content should be in?
The error is thrown by your database server (i.e. MySQL). It seems that MySQL does not have the required permission to access the files where it stores the table data.
Usually, those files are handled (i.e. created, updated, and eventually deleted) entirely by MySQL which requires specific access patterns to ensure consistent data. Because of that, you should strongly avoid to manually change any files under control of MySQL. Instead, you should only use SQL commands to update table structures and table data.
o fix this issue now, you need to fix the permissions of your MySQL data files so that MySQL can properly access them. What exactly is required here is unfortunately not simply explained since there can be various causes. If you have jsut setup your MySQL server, it might be best start entirely new.
I am working with the libmysqld c library in a C++ application on windows in order to interface with an embedded mysql server i.e. a mysql server that is online for the lifetime of the process that embeds it. The application that creates the database uses a mysql .ini file for creating the datadir relative to the application directory instead of in the global mysql install folder e.g.
[libmysqld_server]
basedir=./
datadir=./Database
I can programatically create a trigger with no problem e.g.
status = mysql_query(mysql,
"CREATE TRIGGER del_trigger AFTER DELETE ON table FOR EACH ROW\
INSERT INTO otherTable (col1, col2) VALUES (OLD.col1, OLD.col2)\
");
if (status == 0) {
Log(DEBUG, "Initialize(): <%p> Delete Trigger creation passed ...", this);
}
else {
Log(DEBUG, "Initialize(): <%p> Delete Trigger creation failed with error %s...", this, mysql_error(mysql));
}
The problem I run into however is that when the trigger gets called, mysql will complain that the mysql.proc table does not exist because I do not have a mysql database inside my application specific datadir. I have tried copying the mysql folder from the installation directory in C:\Program Files\MySQL... but then I run into issues where mysql reports
Error:Cannot load from mysql.proc. The table is probably corrupted
The only advice I have seen related to the above error is to run the 'mysql_upgrade' command which does not seem to work for the case of an embedded database using its own datadir. I'm at the point where all of the tables are created and their respective triggers are setup but just can't get around this mysql.proc error.
UPDATE:
I am also seeing some inconsistent behavior here. My version of MySQL is "mysql-5.5.16-win32" and it comes with a mysql_embedded.exe binary that I can use to open up a console and point to the database files generated by my application when it isn't running. When I perform operations in the mysql_embedded.exe, the triggers work without issue (no 'mysql.proc is probably corrupted' errors). So it seems like only the libmysqld c api is having an issue with the mysql system tables.
The solution was as simple as verifying that the "mysql" database was the same version as mysql version embedded in libmysqld. I verified my client version info via the following:
const char * version = mysql_get_client_info();
This returned "5.1.44" instead of the "5.5.16" that I was expecting. Downloading the mysql ZIP archive for 5.1.44 and using the mysql database in the datadir fixed the issue that I was experiencing.
Does anyone know how to export registered servers in Aqua Data Studio? Maybe there's some tricky method to do it by copying some .ini file or registry keys?
AD Studio server registrations are in [USER_HOME]/.datastudio/connections directory. You can copy your existing connections from one machine to another.
AquaFold's documentation about copying registrations from one computer to another is here:
https://www.aquaclusters.com/app/home/project/public/aquadatastudio/wikibook/Documentation16/page/128/Configuration-Connection-files#copy
*** Note: make sure you take a backup of the .datastudio before replacing files.
To Export the connections please make sure you have a fresh installation of aqua data studio on the other system and you haven't set up any new connections.
1) Simply go to C:\Users[userName]\.datastudio
copy folders, files below and place in the same location of the new system:
C:\Users[userName]\.datastudio\connections
C:\Users[userName]\.datastudio\bigquery
C:\Users[userName]\.datastudio\pfile.properties
pfile.properties has the cipher key to decrypt passwords on the system.
I initially only copied the connections folder and found none of my passwords worked anymore. Then I added the pfiles.properties file. That fixed the password problem, but when I tried to open a Query Analyzer window on any of my many MS SQL Server registered servers, I got an error: Id 18456, Level 14, State 1, Line 1 Login failed for user '<username>'.
By copying the rest of the files and subfolders in the .datastudio folder (except for the history which I didn't need and the license files as I had to renew my license anyway), the error was cleared. Bottom line, copy the entire .datastudio folder to transfer your configuration to the new machine, as is documented in the aquaclusters Wiki link: "Copying this directory to a new computer copies all of your current ADS customizations and server registrations."
I am newbie to informatica.
I am using INFORMATICA 9.1.0 and oracle 11g as source and target database.
I tried to create one table in target database and tried to load data from source to target.
Table is getting created in target database. and I created mapping and workflow which is valid and i start work flow but it gave me following error.
Message Code RR_4036

please help me with good solutions.
I got solution for this.
Previously while creating remote connection in Relational Connection Editor for a session, In code page option i chose "UTF-8 encoding of unicode". Now i changed to "ms windows latin 1 (ansi) superset of latin1" and I restarted the workflow which is succeeded.
The following video link shows how to create relational connection for a session.

The problem:
My C++ application connects to a MySQL server, reads the first/header line of each db export.txt, makes a create table statement to prepare for the import and executes that against the database (no problem with that, the table appears just as intended) -- but when I try and execute the LOAD DATA LOCAL INFILE to import the data into the newly created table, I get the error "The used command is not allowed with this MySQL version". But, this works on the CLI! When I execute this command on the CLI using mysql -u <user> -p<password> -e "LOAD DATA LOCAL INFILE 'myfile.txt' INTO TABLE mytable FIELDS TERMINATED BY '|' LINES TERMINATED BY '\r\n';" it works flawlessly?
The Situation:
My company gets a large quantity of database exports (160 files/10gb of .txt files that are '|' delimited) from our vendors on a monthly basis that have to replace the old vendor lists. I am working on a smallish C++ app to deal with it on my work desktop. The application is meant to set up the required tables, import the data, then execute a series of intermediate queries against multiple tables to assemble information in a series of final tables, which is then itself exported and uploaded to the production environment, for use in the companies e-commerce website.
My Setup:
Ubuntu 12.04
MySQL Server v. 5.5.29 + MySQL Command Line client
Linux GNU C++ Compiler
libmysqlcppconn is installed and I have the required mysqlconn library linked in.
I have already overcome/tried the following issues/combinations:
1.) I have already discovered (the hard way) that LOAD DATA [LOCAL] INFILE statements must be enabled in the config -- I have the "local-infile" option set in the configuration files for both client and server. (fixed by updating the /etc/mysql/my.cnf with "local-infile" statements for the client and server. NOTE: I could have used the --local-infile=1 to restart the mysql-server, but this is my local dev environment so I just wanted it turned on permanently)
2.) LOAD DATA LOCAL INFILE seems to fail to perform the import (from the CLI) if the target import file does not have execute permissions enabled (fixed with chmod +x target_file.txt)
3.) I am using the mysql root account in my application code (because its my localhost, not production and this particular program will never run on a production server.)
4.) I have tried executing my compiled binary program using the sudo command (no change, same error "The used command is not allowed with this MySQL version")
5.) I have tried changing the ownership of the binary file from my normal login to root (no change, same error "The used command is not allowed with this MySQL version")
6.) I know the libcppmysqlconn is working because I am able to connect and perform the CREATE TABLE call without a problem, and I can do other queries and execute statements
What am I missing? Any suggestions? Thanks in advance :)
After much diligent trial and error working with the /etc/mysql/my.cfg file (I know this is a permissions issue because it works on the command line, but not from the connector) and after much googling and finding some back alley tech support posts I've come to conclude that the MySQL C++ connector did not (for whatever reason) decide to implement the ability for developers to be able to allow the local-infile=1 option from the C++ connector.
Apparently some people have been able to hack/fork the MySQL C++ connector to expose the functionality, but no one posted their source code -- only said it worked. Apparently there is a workaround in the MySQL C API after you initialize the connection you would use this:
mysql_options( &mysql, MYSQL_OPT_LOCAL_INFILE, 1 );
which apparently allows the LOAD DATA LOCAL INFILE statements to work with the MySQL C API.
Here are some reference articles that lead me to this conclusion:
1.) How can I get the native C API connection structure from MySQL Connector/C++?
2.) Mysql 5.5 LOAD DATA INFILE Permissions
3.) http://osdir.com/ml/db.mysql.c++/2004-04/msg00097.html
Essentially if you want the ability to use the LOAD DATA LOCAL INFILE functionality from a programmatic Connector API -- you have to use the mysql C API or hack/fork the existing mysql C++ api to expose the connection structure. Or just stick to executing the LOAD DATA LOCAL INFILE from the command line :(
