Question

How do I set the database name dynamically in a SQL Server stored procedure?

Answer 1

Stored Procedures are database specific. If you want to access data from another database dynamically, you are going to have to create dynamic SQL and execute it.

Declare @strSQL VarChar (MAX)
Declare @DatabaseNameParameter VarChar (100) = 'MyOtherDB'

SET @strSQL = 'SELECT * FROM ' + @DatabaseNameParameter + '.Schema.TableName'

You can use if clauses to set the @DatabaseNameParameter to the DB of your liking.

Execute the statement to get your results.
