Selecting from a table where the name is passed as a variable

Question

I am trying to write a simple stored proc which takes three arguments \'database name one\', \'database name two\' and \'table name\'. The sql will then perform a row count

Answer 1

You'd have to use dynamic sql, and concatenate the table name into the SQL string to then execute via sp_executsql:

select @sqlstring = 'select @numrowsOUT = count(*) from ' + QUOTENAME(@tablename)
EXECUTE sp_executesql ....
