Definiing variables in connection string

Hi,
I have a web application which connects to database (using DataSource thru JNDI lookup) through Microsoft SQL Server JDBC Driver. The application server is JBoss. Now in the connection string i also want to put a variable "hostname" with its value being the login id of the current user of the web application. How can I do that? I then would acces the connection string to get the current login id from the "hostname" variable. I know there are other ways to save the login id (like in HttpSession) but in my case I have to make it a part of the connection string.
Thanks

This one was my fault. The connection string was not the issue. It was the SQL command I was sending. The terminating semicolon had to be removed.

Using variable in connection string returns 0 for variable.

hi all- I am pulling data from a visual forxpro database and the connection string is as follows:
Data Source=\\ServerName\FolderName\AR;User ID=Domain\svcAct;Provider=VFPOLEDB.1;Persist Security Info=True;
I created a variable called CurrentARPath and stored the path
\\ServerName\FolderName\AR
I then tried using this variable in the Expression property of the connection string as follows:
"Data Source="+(DT_WSTR, 20)@[User::CurrentARPath] + ";User ID=Domain\\svcAct;Provider=VFPOLEDB.1;Persist Security Info=True;"
However, the above expression is evaluating the variable to 0 as shown below; this is causing the connection in connection manager to go down(offline) and the OLED data source is complaining.
Data Source=0;User ID=Domain\svcAct;Provider=VFPOLEDB.1;Persist Security Info=True;
any idea what i am doing wrong here? thanks in advance!

What datatype is CurrentARPath? Are there any
configurations on the connection string or variable?
Which
package protection level are you using?
CurrentARPath data type - Char
there are no configurations on the connection string. one thing that i should mention is that i have created a variable called ArPath of type object and using it in the for each loop container. this variable gets populated using an execute SQL statement.
i am then mapping the vale from ArPath to CurrentARPath in the loop container.
Package protection level is default(encrypt sensitive)
thanks for the help.

Setting substitution variable to connection string (not ODBC name)

Hi,
I havce a question regarding the use of a sub variable in SQL data loads as the data source. I find this works great when the variable is set to an existing ODBC. What I would really like to do is skip the ODBC creation step and have the substitution variable be the actual connection string, such as "Driver={SQL Native Client};Server=myServerAddress;Database=myDataBase; Uid=myUsername;Pwd=myPassword;"
Can anyone confirm or deny whether this functionality exists? As usual, the documentation is vague on the subject and doesn't exclude the possibility, but doesn't include it, either.
Thanks!

My first thought is that no, you can't do that. Even if you could, I'm not sure if you'd want to do that. The easiest way to find out is simply to try. But more than likely I think you should just have "hard-coded" values for the source/target server. If you are trying to stay with the same load rule for dev/test/prod servers, you might just be better off coming up with a naming scheme that let's you keep them all separate.

Unix Environment variable for connect string in SQL*Plus

I am using some environment variables to connect to a sql*plus session in unix.
they are exported as part of a file which contains the following and gets executed through the .profile.
export db_username=xxx
export db_password=xxx
export db_name=xxx
i have created a file abc.sql which contains the following
connect $db_username/$db_password@$db_name
Now, I have a shell script which uses this file inside it to connect to a sql*plus session and execute some queries.
The contents of the shell script :
API_CONNECT_SQL=abc.sql
sqlplus /nolog << THEEND
WHENEVER SQLERROR EXIT SQL.SQLCODE ROLLBACK
WHENEVER OSERROR EXIT FAILURE ROLLBACK
set timing on
@${API_CONNECT_SQL}
---- do something
EXIT
THEEND
Now, the sql*plus session is able to get db_username and db_password, but not the db_name. It says "TNS service name not found".
If I hardcode some database name in place of db_name, it connects properly.
Please let me know the problem and solution as well.
Any help appreciated.
thanks,
Vijay

for me this one works
# =========================================
# begin of script
# =========================================
export db_username=alpha

Dynamically Setting a Variable from a Connection String that has been set by a Config File

Hi Guys
I'm setting up a Master / Slave (Parent / Child) dtsx environment but I'm unable to work out how to dynamically set a variable in the Master dtsx from a connection string that has had its value set by a config file. I'm sure it's possible.
Below is the what I'm hoping to achieve. I've set up everything apart from the highlighted section.
Any ideas?

First, what version of SQL Server are you using?
You could switch the problem around. You could set the value of a variable from the config file, then it is easy to use that variable as the connection string source for your connection manager. At the same time you can use a parent variable
configuration to map that variable to variables in your child package.

How to create dynamic connection string with variables using ssis.

Hello,
Can anyone let me know on how to create dynamic connection string with variables using ssis?
Any help would be appreciated.

Hi vinay9738,
According to your description, you want to connect multiple database from multiple servers using dynamic connection.
If in this case, we can create a Table in our local database (whatever DB we want) and load all the connection strings. We can use Execute SQL Task to query all the connection strings and store the result-set in a variable of object type in SSIS package.
Then use ForEach Loop container to shred the content of the object variable and iterate through each of the connection strings. And then Place an Execute SQL task inside ForEach Loop container with the SQL statements we have to run in all the DB instances.
For more details, please refer to the following blog:
http://sql-developers.blogspot.kr/2010/07/dynamic-database-connection-using-ssis.html
If there are any other questions, please feel free to let me know.

How to build a connection string if "Only variable names (i.e.: $variable) may be used as the target of an assignment statement."

im looping through databases on a server & building a connection string to each database.
$SQLConn.ConnectionString = "Server=$SrvName; Database=$DBName; User ID =DBLogin; Password=myPassword;"
The problem is i get this error:
Only variable names (i.e.: $variable) may be used as the target of an assignment statement
I can put the code into an Inlinescript, but then I lose the ability to perform paralellism. Is there any way to construct the connection string in PS Workflow without using an Inlinescript?

Hi Winston,
Why not just wrap the InlineScript blocks in a Parallel block, to cause them to execute in parallel?
For example:
workflow foo {
parallel {
inlinescript {
start-sleep -Seconds (Get-Random -Minimum 1 -maximum 5)
"a"
inlinescript {
start-sleep -Seconds (Get-Random -Minimum 1 -maximum 5)
"b"
Sometimes outputs "a b" and sometimes outputs "b a"

Parent Variable Configuration - Passing Connection strings..

I have one parent package and a few child packages. I am using SQL Server 2008 R2.
I want to pass variables from Parent Package containing Connection String and other data to the child package. I created few variables in parent package e.g. ParentConnectionString & child package e.g. ChildConnectionString. I set the child package variables
using Package Configurations > Configuration Type = Parent package variable and map the ChildConnectionString value to ParentConnectionString.
I have put a script component that displays variables value set in the child package from parent package.
In child package i have a Connection of ConnectionManagerType = OLEDB. I have added an expression to set the ConnectionString using the ChildConnectionString.
When i run the parent package during the validation phase, it calls the child package. The script component displays the values are being set in child package from parent package but after that it fails saying - invalid username/password; logon denied.
I suspect that the connectionstring expression are going to be executed at run time and not at validation time.
If i put the complete connection string in ChildConnectionString it works fine.
I am not sure if i am doing anything wrong?

It could be that you simply need to put the DelayValidation property to True.
Thing is, when the package starts it validates itself; but at this time the design time connection string property is used, whereas the "real" conn string has been designed to come at a later - runtime, hence you need to set the DelayValidation to true to
make the package not checking the connectivity in advance, and thus successfully start.

Powershell use Connection String to query Database and write to Excel

Right now I have a powershell script that uses ODBC to query SQL Server 2008 / 2012 database and write to EXCEL
$excel = New-Object -Com Excel.Application
$excel.Visible = $True
$wb = $Excel.Workbooks.Add()
$ws = $wb.Worksheets.Item(1)
$ws.name = "GUP Download Activity"
$qt = $ws.QueryTables.Add("ODBC;DSN=$DSN;UID=$username;PWD=$password", $ws.Range("A1"), $SQL_Statement)
if ($qt.Refresh()){
$ws.Activate()
$ws.Select()
$excel.Rows.Item(1).HorizontalAlignment = $xlCenter
$excel.Rows.Item(1).VerticalAlignment = $xlTop
$excel.Rows.Item("1:1").Font.Name = "Calibri"
$excel.Rows.Item("1:1").Font.Size = 11
$excel.Rows.Item("1:1").Font.Bold = $true
$filename = "D:\Script\Reports\Status_$a.xlsx"
if (test-path $filename ) { rm $filename }
$wb.SaveAs($filename, $xlOpenXMLWorkbook) #save as an XML Workbook (xslx)
$wb.Saved = $True #flag it as being saved
$wb.Close() #close the document
$Excel.Quit() #and the instance of Excel
$wb = $Null #set all variables that point to Excel objects to null
$ws = $Null #makes sure Excel deflates
$Excel=$Null #let the air out
I would like to use connection string to query the database and write results to EXCEL, i.e.
$SQL_Statement = "SELECT ..."
$conn = New-Object System.Data.SqlClient.SqlConnection
$conn.ConnectionString = "Server=10.10.10.10;Initial Catalog=mydatabase;User Id=$username;Password=$password;"
$conn.Open()
$cmd = New-Object System.Data.SqlClient.SqlCommand($SQL_Statement,$conn)
do{
try{
$rdr = $cmd.ExecuteReader()
while ($rdr.read()){
$sql_output += ,@($rdr.GetValue(0), $rdr.GetValue(1))
$transactionComplete = $true
catch{
$transactionComplete = $false
}until ($transactionComplete)
$conn.Close()
How would I read the columns and data for $sql_output into an EXCEL worksheet. Where do I find these tutorials?

Hi Q.P.Waverly,
If you mean to export the data in $sql_output to excel document, please try to format the output with psobject:
$sql_output=@()
do{
try{
$rdr = $cmd.ExecuteReader()
while ($rdr.read()){
$sql_output+=New-Object PSObject -Property @{data1 = $rdr.GetValue(0);data2 =$rdr.GetValue(1)}
$transactionComplete = $true
catch{
$transactionComplete = $false
}until ($transactionComplete)
$conn.Close()
Then please try to use the cmdlet "Export-Csv" to export the data to excel like:
$sql_output | Export-Csv d:\data.csv
Or you can export to worksheet like:
$excel = New-Object -ComObject Excel.Application
$excel.Visible = $true
$workbook = $excel.Workbooks.Add()
$sheet = $workbook.ActiveSheet
$counter = 0
$sql_output | ForEach-Object {
$counter++
$sheet.cells.Item($counter,1) = $_.data1$sheet.cells.Item($counter,2) = $_.data2}
Refer to:

How to determine the connection string to a SQLite database, in C# code

Hello. I'm trying to figure out how to specify the connection string to a SQLite database, I would like to access using the following code:
string connectionString = null;
SqlConnection connection;
SqlCommand command;
SqlDataAdapter adapter = new SqlDataAdapter();
DataSet ds1 = new DataSet();
string sql = "SELECT DataName, Data, Id, UserId, DateLastUpdated FROM MainTable";
connectionString = "Data Source=C:\\SQLITEDATABASES\\SQLITEDB1.sqlite;Version=3;";
connection = new SqlConnection(connectionString);
try
connection.Open();
command = new SqlCommand(sql, connection);
catch
The value I assigned to the variable connectionString, in the code above, I obtained somewhere from the Internet. It does not work. I'm using Visual Studio 2013, against the file sqlite-netFx451-setup-bundle-x86-2013-1.0.96.0.exe, which
I installed, and got from
here.
My application's App.config file looks as follows:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
</configSections>
<connectionStrings>
<add name="DC_Password_Saver.Properties.Settings.DC_Password_SaverConnectionString" connectionString="data source="C:\Users\patmo_000\Documents\Visual Studio 2013\Projects\DC Password Saver\DC Password Saver\DC Password Saver.db"" providerName="System.Data.SQLite.EF6"/>
</connectionStrings>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.1"/>
</startup>
</configuration>
I tried to use the value assigned to connectionString in the XML settings above, replacing single backslash characters with double backslash characters, because the Visual Studio editor flagged them as unrecognizable, and wound up with the
following.
SqlDataAdapter adapter = new SqlDataAdapter();
DataSet ds1 = new DataSet();
string sql = "SELECT DataName, Data, Id, UserId, DateLastUpdated FROM MainTable";
connectionString = "data source="C:\\Users\\patmo_000\\Documents\\Visual Studio 2013\\Projects\\DC Password Saver\\DC Password Saver\\DC Password Saver.db"";
connection = new SqlConnection(connectionString);
The above code however does not work either. So again, does anyone know how I can specify in C# code, a connection string to access my SQLite database? Thanks in advance for your reply.

What does SQLite connection strings has to do with WPF?
You will find some valid connection strings here:
https://www.connectionstrings.com/sqlite/
But you cannot use the SqlConnection class to connect to a SQLite database. You will need to download and add a reference to the System.Data.SQLite library and then use the SQLiteConnection class:
connection = new System.Data.SQLite.SQLiteConnection(connectionString);
try
connection.Open();
command = new System.Data.SQLite.SQLiteCommand(sql, connection);
catch
Please refer to the following article for more information and an example of how to connect and read and write data from an SQLite database using C#:
http://blog.tigrangasparian.com/2012/02/09/getting-started-with-sqlite-in-c-part-one/.
There is contains a link where you can download the required assemblies.
Hope that helps.
Please remember to mark helpful posts as answer to close your threads and then start a new thread in an approproate forum if you have a new question.

Changing connection string host from localhost to IP address produces error

Hi all,
First of all, thanks in advance for your help. Second, I know next to nothing about Oracle database administration, so please be patient, but I want to understand things, rather than just running down the Google rabbit hole with guess-and-check until things happen to work and I don't know why.
I've got a connection string that I'm using to connect to a local Oracle database I'm using for testing. I have the 11g installed and the 11.1.0.7 64-bit client (as my application is a 64-bit application) installed, both locally on my development machine. I've got a connection working using the following connection string:
Data Source=(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))(CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = mywindowslogin.path.to.me)));User Id=********;Password=********;However, when I change "localhost" to my IP address, my computer name, or anything else, I get "ORA-12541: TNS:no listener".
The tnsnames.ora in my database home is as follows - it was set up for me automatically when I installed the database. mywindowslogin.path.to.me doesn't point to anywhere, which I assume is correct, but my computer is on the path.to.me domain.
LISTENER_MYWINDOWSLOGIN =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
MYWINDOWSLOGIN =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = mywindowslogin.path.to.me)
)How can I resolve this issue?
Edited by: Don on Jul 14, 2010 8:31 AM

Does setting the environment variable affect all installations? Only two of my four Oracle Homes have a tnsnames.ora file, or event a NETWORK/ADMIN location, so I'm not sure where to put tnsnames.ora in those Homes. I copied the tnsnames.ora for my database to the one other Home that had a NETWORK/ADMIN location, but I'm still getting "ORA-12541: TNS:no listener" if I don't use "localhost" as the host.
Thanks!

Set SSIS variable = database connection manager name

Is it possible to set a SSIS string to only the name of a database connection manager or even the connection string it uses ? I don't see an option for that in Evaluate as expression property of ssis variable.
This is what I mean -
SSIS Connection manager name = SQL_DBASE
SSIS String str_managerName = SSIS Connection manager name: Can you do this dynamically in SSIS ?

I'm guessing what they really want to do is evaluate some indicator (some input from a user or an infrastructure setting) and then dynamically connect to any one of 10 (arbitrary example) database servers based on what they get as input. They
don't care about the connection manager per se. What seems reasonable is the that the Connection Manager might take a server variable but if they wanted to do things like that they would have bought Datastage.
You might try attacking this problem at the Control Level and then connect to the database you want based on a variable you set. I'm seeing that a Sequence Container can branch on the contents of a variable.
Or if the dba is your friend you might get the dba to add all your servers as linked servers to a central connection machine and then you might be able to do this by putting the ssis variable in a "Sql Command from a Variable" variable.
It might look something like this:
Server is designated in ssis var @[User::Machine]
then executing from a variable
"select top 100 * from " + @[User::Machine] + ".mydb.dbo.mytable"
Be careful as hades about levels of indirection and what quotes you want at what level. Evaluate Expression in ssis helps with this. The syntax I show works only with an ms sql connection server to a remote ms sql server. This is what a
dynamic connection to a linked server connection to Oracle would look like:
"select * from
openquery("+ @[User::Machine] + ",'select * from oradb.oratable where rownum < 100')"
When ever a thousand of your best friends are helping you connect to your database (using tools like linked servers as opposed to direct connections) it's probably best to use with only small specific updates or queries, large queries or large
updates would probably take a long time and or might not finish. But try it before you give up. We are actually doing fairly large Oracle queries (5-10 million rows) through ms sql linked server.

Security and connection string

Hi,
   I am a new developer using ColdFusion.
   Does ColdFusion support Windows Authentication or I have to have my connection string in plain text in my cfm files?
   Can I have connection string in my form or I have in one config file?
   Is it possible to encryp my password and user name in the cfm file?
   Your information and help is great appreciated,
   Regards,
iccsi,

That is a broad question. Are you referring to connections to data sources, or recognizing user IDs for site logins? If the former, you can configure the database logins (with some caveats) within the secure CF Administrator, and never have to pass credentials directly in your CFML code. As for user IDs for logins, if you configure your webserver (IIS) to use Windows Authentication via NTLM, Coldfusion will receive the Windows login and make it acccessible to you via CGI variables.

Hi Pandiyanpvp,
According to your description, the OLEDB Destination Connection String should be dynamically based on the OLEDB Source Connection String. They are all the same, except adding “DW” at the end of the Database of OLEDB Source Connection String in OLEDB Destination
Connection.
To achieve this requirement, we can create a variable with the Database name of OLEDB Source Connection String, then use expression to control the OLEDB Source and OLEDB Destination Connection Strings. For more details, please refer to the following steps:
Create a variable named Source with the Database name of OLEDB Source Connection String as value.
Click the OLEDB Source Connection Manager to navigate to the Properties window.
Click “…” next to Expressions to add a ConnectionString Property with the expression like below:
"Data Source=.;Initial Catalog="+@[User::Source] + ";Provider=SQLNCLI11.1;Integrated Security=SSPI;Auto Translate=False;"
Click the OLEDB Destination Connection Manager to navigate to the Properties window.
Click “…” next to Expressions to add a ConnectionString Property with the expression like below:
"Data Source=.;Initial Catalog="+ @[User::Source] + "DB"+";Provider=SQLNCLI11.1;Integrated Security=SSPI;Auto Translate=False;"
If there are any other questions, please feel free to ask.
Thanks,
