VS 2008 Data Project. Create tables in different schema's
Hi there,
I have a database project that creates tables. Some of the table structures are the same but are unique to a particular currency. So say I have a table called CurrencyQuote and I want one for each currency then what I done was create a Schema for each currency and then create that table in the schema.
However I want to Automate this from VS 2008 database project and dont want to create a table script for each currency when the only thing different is the schema that it goes into. Also if I want to add a column to the table I have to update all the curreny tables rather than just updaing the one table and then running it against the various schemas.
Any ideas on this ... thanks Mick

emmh, kinda like the idea of using a sproc to create the tables 8080. I could also add it to a list of tables and inside my sprocs to get the data, I could check if the table was supported... Emmhh got me thinking 8080.
As for the partitions, at the time I read a fair bit on this approach and I was going to go for it, but there was a few gotcha's that I didnt like and cant remember... joys of getting old... I mean older :-)
Tick data is fairly intensive and this approach seemed to also be used by a few other people in the same game.
So all in all 8080, you dont think VS 2008 Db proj can handle this, which is my gut feeling also... but you have give me a viable solution. If I dont hear another in the next day... points are yours for imagination :-) thanks Mick

I have 7 currencys which I recieve may 100 quotes a sec for... add this up over a period and the table gets big. So I,ve broken the table into 7 tables and used the Schema for each so I would have 7 schema..called EUR, GBP, USD etc and a table called Currency quote in each.
I have 1 stored proc that is called and depending on the Currency passed in I update the table in that schema. When the tables get big, I aggregate the data up and delete some of the historial data. I do this to keep the tables light as I also need to read from them. This imho is faster than creating one big table.
Hope this explains a bit of the madness.
However I have a VS 200 database project and what I do is I have a schema script for each Currency. I then want to put the one currencyquote table, into each schema.. so really I want to loop for each schema and create a table in it.
Now all I want to know, is there a way to automate such a process in VS 2008 DB project. Instead I have 7 tables created for each schema... eg Create Table EUR.CurrencyQuote ... Create Table GBP.Currency quote. If I want to add a column I need to change the 7 create scripts.
I hope this explains what I mean.
All the best and thanks Mick
