Deprecated
Data Access Layer (DAL) is deprecated. While the existing code keeps working, we recommend switching to Database API.
In the Enterprise Edition of ASPRunnerPro you can use multiple database connections in a single project. This article explains how you can access data from multiple databases in your events.
Method 1: using DAL functions
There are three options to refer to a table:
1. Finds the first matching table by its name in all connections, starting with the primary connection.
dal.Table("table")
2. Finds the tables by the table name and schema name.
dal.TableSchema("table", "schema")
3. Finds the table by the table name, schema name and connection name. The schema name can be left empty, and the last parameter is the connection name as it appears on Datasource tables screen.
dal.TableSchemaConn("table", "schema", "connection")
4. Finds the table by the table name and connection name.
dal.TableConn("table", "connection")
A complete code example:
set data = dal.TableConn("carscars", "cars at localhost").QueryAll()
while not data.eof
Response.Write data("Make") & ", " & data("Model") & "<br>"
data.MoveNext
wend
data.close : set data=nothing
Method 2: using free form SQL Queries
Here is how to update all cars where make is Audi and the YearOfMake equals 2002:
cman.byName_p1("cars at localhost").query_p1("Update carscars set yearofmake=2002 where make='Audi'")
