how would you make a stored procedure that takes as a parameter a list of fields and their values to update and another parameter with where arguments and do an update for a certain table with this?

in mysql you could do something like this inside a stored procedure...
SET @stmnt= CONCAT(UPDATE mytable SET ‘,@update_agrs,' WHERE', @where_args);
PREPARE stmnt FROM @stmnt;
EXECUTE stmnt;
can you do something like this in sql server where you can construct a query with arguments for column names, and update values.  the thing i haven't found is how to get text in a parameter to be used as column names in a query.
thanks

hi hillelben:

you can do the following

Declare @QRY varchar(1000)

set @QRY = 'Update Table set col1 = ' +  5 + ' where name = ''jack''; '

Exec (@QRY)
