Answer 1

Yep, you can generate an SQL statement dynamically and then execute it.

For example,

DECLARE @specificTableName nvarchar(50)
DECLARE @specificColumnName nvarchar(50)

SET @specificTableName = 'tblSpecific'
SET @specificColumnName = 'colSpecific'

DECLARE @sql nvarchar(4000)

set @sql = 'SELECT ... FROM tblCommon c INNER JOIN ' +
@specificTableName + ' s ON c.PrimaryKey = s.' + @specificColumnName


exec (@sql)
