SSIS Double Backslash is causing connection issues

问题

I'm currently using an Execute SQL Task to pull in dynamic information to build my connection string for each of my databases. From there I'm passing them to a Foreach Loop. At this point I'm building my connection string using an expression:

"Data Source="+ @[User::DatabaseServer]+ "\\"+@[User::Instance]+";User ID="+@[User::UserName]+ ";Password="+ @[User::Password] +";Initial Catalog=Defaul;Provider=SQLNCLI10.1;"

My issue is the following, when my connection string is built with a double backslash.

Data Source=DatabaseServer\\InstanceName;User ID=UserName;Password=Password;Initial Catalog=Default;Provider=SQLNCLI10.1;

Does anyone know how to prevent the double backslash from occurring? I've tried to use the escape characters but I have had 0 success.

回答1:

i found a work around of the issue  :


what I have done is :

I have taken the first parameter for connction string like : "anystaring
and the second parameter for the db is :  newdb"

so now check the screenshot I have given the URL(not able to upload the image sorry):
