''' SF_Database
|
||||
''' =========
|
||||
''' Management of databases embedded in or related to Base documents
|
||||
''' Each instance of the current class represents a single database, with essentially its tables, queries and data
|
||||
'''
|
||||
''' The exchanges with the database are done in SQL only.
|
||||
''' To make them more readable, use optionally square brackets to surround table/query/field names
|
||||
''' instead of the (RDBMS-dependent) normal surrounding character (usually, double-quote, single-quote or other).
|
||||
''' SQL statements may be run in direct or indirect mode. In direct mode the statement is transferred literally
|
||||
''' without syntax checking nor review to the database system.
|
||||
'''
|
||||
''' The provided interfaces include simple tables, queries and fields lists, and access to database metadata.
|
||||
'''
|
||||
''' Service invocation and usage:
|
||||
''' 1) To access any database at anytime
|
||||
''' Dim myDatabase As Object
|
||||
''' Set myDatabase = CreateScriptService("SFDatabases.Database", FileName, , [ReadOnly], [User, [Password]])
|
||||
''' ' Args:
|
||||
''' ' FileName: the name of the Base file compliant with the SF_FileSystem.FileNaming notation
|
||||
''' ' RegistrationName: the name of a registered database (mutually exclusive with FileName)
|
||||
''' ' ReadOnly: Default = True
|
||||
''' ' User, Password: additional connection arguments to the database server
|
||||
''' ' ... Run queries, SQL statements, ...
|
||||
''' myDatabase.CloseDatabase()
|
||||
'''
|
||||
''' 2) To access the database related to the current Base document
|
||||
''' Dim myDoc As Object, myDatabase As Object, ui As Object
|
||||
''' Set ui = CreateScriptService("UI")
|
||||
''' Set myDoc = ui.OpenBaseDocument("myDb.odb")
|
||||
''' Set myDatabase = myDoc.GetDatabase() ' user and password are supplied here, if needed
|
||||
''' ' ... Run queries, SQL statements, ...
|
||||
''' myDoc.CloseDocument()
