问题 I have a customer table, and a detail table. I want to want to pull a record for every customer in the table and show the latest detail data on that customer where applicable. Currently my where clause is filtering out customers. I have tried moving the where clause into the left outer join, but I have not been able to get the desired result. It does not seem to filter the product at all when I run the query. SELECT cust.Customer , cust.Company , inv.Date , inv.Product , inv.Units , inv

问题 We're connecting to an Ads server with a .net application using the Advantage .NET Data Provider. The ServerType = REMOTE. The max. connections on the server is set to 150.

问题 Our EMR software uses Advantage Database SQL server as its database and I'm creating various PHP projects which require interaction with this database. What is the best approach to connecting and working with Advantage DB SQL and PHP? I'd like to connect on a read-only level to prevent any data wrong-doing with insurance/patient/provider records. Note: I connect to other databases using PDO drivers. Is there an Advantage DB driver for PDO that I'm unaware of? Server info: PHP, Windows 2008,

问题 I need to create an ERD for an ADS 10 database. Reverese Engineering would be nice, since the database already exists. Unfortunately, I didn't found a ERD-Tool which supports this database. Does anybody knows a tool which supports this features? 回答1: You can use the Advantage Data Architect to get a model of a database. As far as I know this only works on data dictionaries, but you can easily add free tables to a dictionary if necessary. I don't know of any other ADS compatible modelling

问题 I am running into what seems to me to be a bug in the Advantage Database PHP Extension (I know, I know...). I've reported it as a bug, but still haven't heard anything back, so I thought I'd run it by you guys. Working Code: for ($i = 0; $i < 100; $i++) { $connection = ads_connect( 'DataDirectory=\\some\path\;ServerTypes=2;RightsChecking=Off;TrimTrailingSpaces=true;CommType=TCP_IP;', '', '' ); $results = ads_do( $connection , 'SELECT TOP 1 * FROM projects'); ads_close( $connection ); } This
