Retrieving SQL Connection Data

Aspose.Cells for Python via .NET can help you retrieve SQL connection data. This includes any and all data that is required to make a connection to the SQL server, for example, server URL, username, table name, full SQL query, query type, location of the table, and name of the named range associated with it.

In Microsoft Excel, connect to a database by:

1. Clicking the Data menu and selecting From Other Sources followed by From SQL Server.
2. Then select Data followed by Connections.
3. Use the Connections wizard to connect to the database and create a database query.

Aspose.Cells for Python via .NET provides the Workbook.DataConnections property for retrieving external connections. It returns a collection of ExternalConnection objects in the workbook.

If the ExternalConnection object contains SQL connection data, it can be type-caste to a DBConnection object and its properties can be used to retrieve database command, command type, connection description, connection information, credentials, and so on.

from aspose import pycore
from aspose.cells import Workbook
from aspose.cells.externalconnections import DBConnection


#  The path to the documents directory.
dataDir = "./"
#  Create a workbook object from source file
workbook = Workbook(dataDir + "connection.xlsx")
#  Access the external collections
connections = workbook.data_connections
connectionCount = len(connections)
connection = None
for i in range(connectionCount):
    connection = connections[i]
    #  Check if the Connection is DBConnection, then retrieve its various properties
    if connection is DBConnection:
        dbConn = pycore.cast(DBConnection, connection)
        #  Retrieve DB Connection Command
        print("Command: "  + dbConn.command)
        #  Retrieve DB Connection Command Type
        print("Command Type: "  + str(dbConn.command_type))
        #  Retrieve DB Connection Description
        print("Description: "  + dbConn.connection_description)
        #  Retrieve DB Connection ID
        print("Id: "  + str(dbConn.connection_id))
        #  Retrieve DB Connection Info
        print("Info: "  + dbConn.connection_info)
        #  Retrieve DB Connection Credentials
        print("Credentials: "  + str(dbConn.credentials_method_type))
        #  Retrieve DB Connection Name
        print("Name: "  + dbConn.name)
        #  Retrieve DB Connection ODC File
        print("OdcFile: "  + dbConn.odc_file)
        #  Retrieve DB Connection Source File
        print("Source file: "  + dbConn.source_file)
        #  Retrieve DB Connection Type
        print("Type: "  + str(dbConn.type))
        #  Retrieve DB Connection Parameters Collection
        paramCollection = dbConn.parameters
        paramCount = len(paramCollection)
        #  Iterate the Parameter Collection
        for j in range(paramCount):
            param = paramCollection[j]
            #  Retrieve Parameter Cell Reference
            print("Cell reference: "  + param.cell_reference)
            #  Retrieve Parameter Name
            print("Parameter name: "  + param.name)
            #  Retrieve Parameter Prompt
            print("Prompt: "  + param.prompt)
            #  Retrieve Parameter SQL Type
            print("SQL Type: "  + str(param.sql_type))
            #  Retrieve Parameter Type
            print("Param Type: "  + str(param.type))
            #  Retrieve Parameter Value
            print("Param Value: "  + str(param.value))
