Click the Parameters button to the right of the command text field. Parameters are mapped to variables so that the values can be used in the SQL commands. The question mark in the SQL command is referred to as a parameter. The process date value is being stored in a variable, so the first step in accessing that variable is to add a question mark in the query in place of the variable name that you would typically use when running the statement in SSMS. Take note of the WHERE clause in the following image. In my example, I am using a basic select statement that is returning all the fields that I want to archive. In the SQL command text field that opens up below, paste your SQL statement. After selecting or creating the connection manager, set the data access mode to SQL Command. Inside the data flow, add an OLE DB Source component and open the editor. In the control flow of the package, I have added a data flow task right after the Execute SQL task. For today’s example, I am using the same package from last week’s post so that I can add on to it. The task then stores the value it returns in a variable. Once a variable is populated, what can you do with it? It can be used in many different ways throughout the package, however, today, I’ll show you how to use a variable in a TSQL statement in an OLE DB source component.Īs a recap, last week I used an Execute SQL task to pull the max value for a date key that is copied to an archive table (the destination). Last week, I demonstrated a simple way to create variables and how to write a value to those variables using an execute SQL task.
