I am new to SSIS, I have created variables for connection string (Both source and destination). While generating the Config file, which property I need to select. Could you please help me with this?
It's not necessary to create variables for a connection string.
There are a few things you will need to provide to us to give you an exact answer.
The type of database you are connecting to.
What type of authentication you use to connect to it.
If you take the below image when setting up a connection manager for an OLE DB you simply need to provide the server name. Then which type of authentication it is.
If the connection is successful you should be able to select a database you wish to connect to. You can also test the connect to make sure the connection is working successfully.
Let me know if you have any other issues.
Thanks

Is there a way I can view the connection string used by the client to connect to my Postgres instance?
Problem:
I am connecting to Postgres via jasper and I am setting prepareThreshold=0 in the connection string to disable prepared statements. I see that it's not being honoured for some reason. So I would like to confirm that jasper is actually passing the setting in the connection string correctly.
You can ask the database server only for information it has.
prepareThreshold is a setting of the JDBC driver, and the database has no knowledge about it.
You can cast the java.sql.Connection to an org.postgresql.PGConnection and use the getPrepareThreshold() method to get the desired information.
DBIx::Class::Manual::Intro
suggests connecting to the database as follows
my $schema = MyApp::Schema->connect(...)
explicitly providing connection details such as the password.
I want to connect to the same database from multiple different scripts, and it would be unwise to code the same connection parameters into each of the programs separately.
What is the "official" way to create a connection method with fixed connection details?
I realize that I can write something like this
package MyApp::Schema;
use base qw/DBIx::Class::Schema/;
sub my_connect {
$_[0]::SUPER->connect(...);
}
1;
Is this approach recommended?
I realize that providing different connection details may be useful for testing scripts, but in reality we do not yet use testing scripts, so this is currently irrelevant for our team.
Put your connection details in a config file, create a utility to return the connection and read the config details like you showed, or as a factory type function. Make the config dependant on the environment and you'll have testing capabilities for free.
I have a small application written in Go that connects to a PostgreSQL database on another server, utilizing database/sql and lib/pq. When I start the application, it goes through and establishes that all the database tables and indexes exist. As part of this process, it issues a SET search_path TO preferredschema,public command. Then, for the remainder of the database access, I do not have to specify the schema.
From what I've determined from debugging it, when database/sql reconnects (no network is perfect), the application begins failing because the search path isn't set. Is there a way to specify commands that should be executed when it reconnects? I've searched for an event that might be able to be leveraged, but have come up empty so far.
Thanks!
From the fine manual:
Connection String Parameters
[...]
In addition to the parameters listed above, any run-time parameter that can be set at backend start time can be set in the connection string. For more information, see http://www.postgresql.org/docs/current/static/runtime-config.html.
Then if we go over to the PostgreSQL documentation, you'll see various ways of setting connection parameters such as config files, SET commands, command line switches, ...
While the desired behavior isn't exactly spelled out, it is suggested that you can put anything you'd SET right into the connection string:
connStr := "dbname=... user=... search_path=preferredschema,public"
// -----------------------------^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
and since that's all there is for configuring the connection, it should be used for every connection (including reconnects).
The Connection String Parameters section of the pq documentation also tells you how to quote and escape things if whatever preferredschema really is needs it or if you have to grab a value at runtime and add it to the connection string.
I'd like to scope some cells to particular values if the current user is an SSAS admin.
I'm not sure where I'd even begin to determine that kind of introspection. Any ideas would be welcome please.
Note that I'm using UDM and not Tabular models
As a workaround you can append «;EffectiveUserName=» to connection string. Then try to connect and check for exception. This connection is able to establish with administrative rights only.
See here for how to use the SCOPE function in an IF clause. Inside the clause, the USERNAME() function can be used to return the current user(See here). Hope this helps.
Is there any official write-up what forms can Data Source field take in sql server connection string? I'm aware of following forms:
SERVER
SERVER\Instance
tcp:SERVER,port
nb:SERVER
nb:SERVER\Instance
are there more forms?
EDIT: The essence of this exercise is not to construct a connection string. I am trying to parse existing connection string, and I want to know all the forms it could take. I appreciate everybody who pointed me to www.connectionstrings.com, and this site is useful enough, but it clearly does not have all the information. For example, it will not specify that it is possible to use construct like "Data Source=tcp:SERVER,10000" to specify that TCP must be used for this datasource on port 10000.
