Note. If you want to use the values of login and password from variables in the activity “Connect to database“, you need to use “Connection string“ as a method of connection to DB with the following syntax:

`mssql://${username}:${password}@localhost?database=TESTDB2&request%20timeout=25000`

where username​ - is the variable that contains the value of the login; password​ - is the variable that contains the value of the password.
In the mandatory parameter “Login and password“ of this activity you can set any value, it won't affect the performance of the activity.

Connection string

1. Calculate a value: this allows you to use a special formula or a special method to set the query text.

For example, you can use the connection string to set the required timeout value:

`mssql://{{login}}:{{password}}@127.0.0.1?database=demo&request%20timeout=25000`

When using this string, make sure to change the parameter host 127.0.01 , the parameter database demo and the parameter timeout 25000 to required values.
