MS SQL server Meata data question

Tom Jones

I need to use php's native mssql api in order to read the meta data from an
entire DBMS ... I have sql server 2000 up and running and using the provided
browsing tools poked around and found that the databases in the system were
listed under a database named "master" in a table named "sysdatabas es" ...
there is a "syscolumns " table there too but it looks like i need specific
info about the architecture of sql server's inner workings to use it.

the native php support for sql server doesn't have meta data functions like
are provided for things like mysql and odbc. I can't use adodb or pear for
alot of reasons ...

can anyone help me or point me to a souce for how to get:

databases -- I have done this one in a round about way
tables in those databases
attributes in those tables
and attribute types

I need to do this for Oracle too but I think the native support for Oracle
is better and the tools built in ... I think Oracle supports something they
call show commands that just do what I want.

Thanks
Tom

No idea about SQL Server, never used it. However, in Oracle, you look in the
'data dictionary' for metadata; it's a set of views such as USER_TABLES,
USER_TAB_COLUMN S that you query with ordinary SQL.

See: http://otn.oracle.com/pls/db92/db92....emark=homepage

'SHOW' commands are for MySQL - such as 'SHOW TABLES'. You can execute these
as queries and they return a result set, but they're not proper SQL as you
can't have WHERE clauses or use them in joins etc.

Check out the INFORMATION_SCH EMA_* Views, which are well explained in
the MSSQL documentation (BOL). Thats what I use...

Call the store procedure sp_databases and sp_tables to get a list of
databases and tables (in the current database). sp_columns will get your a
list of a table's columns. Look in your MS SQL help file for more info.

A client is panicking about their large Access application, which has been running smoothly with 100s of thousands of records for quite some time. They have a big project in the next year that will lead to a lot of use of the database and the adding of quite a lot of new data (though I can't conceive of them adding more than than 10s of thousands of records, which won't change the current performance profile at all).

Hi all I am developing a multi-user business/accounting application.

Before I go ahead and make the changes, I thought I would bounce it off the group and see if there is a simpler approach.

Is There a Client/Server Version of Access ?

by: B1ackwater | last post by:

We've fooled around with Access a bit, but only using the single-user store-bought version. It seems to be a good database - versatile and infinitely programmable - and can apparently be used as a front end to SQL server if we ever needed to go that route.
