sql server - Checking if multiple entries exist in SQL, delet them and add a new one -


i have table column rowid, personid, activitytypeid, groupid, select above column , works fine.

bit of above table data above data can have data like, same `personid can have multiple activitytypeid , activitytypeid have groupid. this

rowid  personid activitytypeid groupid 1       20          1             2 2       20          2             2 3       20          7             8

now problem is, if particular personid, there more 3 entries in same group. wish delete entries of person while selecting , add new 1 manually. can done in store procedure?

any appreciated.

apologies, if title doesnt make sense.

a stored procedure way go since making multiple calls different tables.

to clear, trying delete entries based on specific personid , add 1 select statement? can done following syntax:

create proc my_sp  @deletedid int, -- id of person trying delete @insertedid int -- id of person trying add begin set nocount on -- ensure select statement not interefered  delete table personid = @deletedid  insert table select * table2 personid = @insertedid end

to call stored procedure use execute statement parameters:
exec my_sp 0123, 5555 0123 id of deleted person , 5555 added one.

if wanted manually pass data insert into instead of using select statement you'll have add more parameters , use 

insert table values(@param1, @param2, @param3, ... etc)

here's link on using insert into may well: http://www.w3schools.com/sql/sql_insert.asp

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
