>>>I am attempting to display a count of the rows in a table called ContactUpdates in the AP Database. However, I am using a variable named @TableNameVar to contain the name of the table which I obtain by using a SQL statement sort of like a derived table, as in this: SET @TableNameVar = 'SELECT MIN(name) from sys.tables' , but it isn't quite working yet. This is for an exercise in my T-SQL class.
