h2. Using the Avoka SQL-Plus DSC
You can save data retrieved from a database into string process variables as concatenated strings or list variables.
The following process [sample|^sql_plus_mulivalues_test.lca] demonstrates how to retrieve data from a database and save the data into string or list process variables. You can import this archive file using archive manager and open it in the process designer.
First, we create variables, called 'names_string', 'emails_string', 'names_list' and 'emails_list' of types 'string' and 'list' and specify its properties as shown on the following picture.

| Optionally, you can check the 'prepared SQL statement' box to create a prepared SQL statement and specify query parameters. To test your statement, click
the 'Test'
button. This will display the first row of the result set retrieved from the database. |

You can specify any delimiter as an arbitrary string.
The second step we retrieve data from the database and save data as elements into the list variables.
The following picture shows settings to save data from database into the list variables.

The third step of the process logs values of all variables and saves the log file into a directory. After we run the process, we can open the log file generated from the data and saved in the local server directory that looks like the one shown in the following picture.

This service is useful when you need to save data from a database as concatenated strings or elements of lists.
