Migrating PHP based "table" to a view or other table.


Recommended Posts

Hi,

 

At the moment I've got two tables: "Sports" and "Groups"  - and I've got a PHP script editing another table which is like a "sports by group" (or "events") eg. seperating different groups of competitors (ages, disabilities... whatever the group is)...  I need the table to have a static ID for each row/"event" generated.... so I cant use a view because it cant have a primary key.

 

Is there an SQL based alternative, that will allow the same final queryable table/view but that will remove the language side of it (like creating a view with primary keys?)

 

Thanks,

Good point....

 

two tables, I need to have a third with all of the other two table's worth of data init - linked with a Primary key....  eg:  in the new table, for each record in the groups table I would have every record from the sports table...  At the moment I can get the data like I want into a view - but those dont allow primary keys ( and understandably)..... At the moment I'm having to "start" the system by using PHP to generate each record into the new table - and then essentially lock access to the other two tables - because changing them could change the new table's data ( which is the "mission critical" thing in the system....

 

Is there an alternative method to this scripting?

groups

--------

group_id int PK

group_name varchar

upper_limit int

lower_limit int

 

sports

-------

sport_id int PK

name varchar

 

 

data:

 

groups

-------

1, "Jnr", 12,15

2, "Snr", 16, 19

 

sports

--------

1,"High Jump"

2, "Long Jump"

 

 

so that my resulting table would be:

 

events

__________

1, 1( sport_id), 1 (group  id)

2, 1, 2

3, 2,1

4,2,2

 

 

At the moment I can acheive a similar thing in a view - however the events table cannot have the primary key .... can I get a primary key in there somewhere?

I'm not sure what you mean by the "INSERT INTO... SELECT...". (as in I know the SQL.. but not what its talkign about table wise).....

 

the events table/view/whatever needs to have a static id to each group/sport id combination ( as I showed in the example events table).... thanks

You can use the resultset from one query as the input for another... the refman has examples.
