Using Python to Operate MarkLogic

To operate the MarkLogic database using Python, you need to use MarkLogic's official Python client library - 'MarkLogic Python Client' This library can be installed through pip. Now let's gradually introduce how to use it to connect and operate MarkLogic databases. ###Connect to the MarkLogic database Firstly, you need to import the 'DatabaseClient' class from the 'marklogic' library and create a database client using the host name, port, username, and password. For example: python from marklogic import DatabaseClient Host='localhost' # MarkLogic host name Port=8000 # MarkLogic Port Username='admin' # username Password='password' # Password client = DatabaseClient(host, port, username, password) ###Data insertion To insert data into the MarkLogic database, you need to use the database client's' new '_ The document 'method creates a new document object and uses' add'_ The content 'method adds the content to be stored. Then, use the 'write' method to write the document to the database. For example: python #Create a new document doc = client.new_document() #Add Content doc.add_content('{"name": "John", "age": 30}') #Write document to database doc_uri = '/people/john.json' client.write(doc, doc_uri) ###Data Query To query data in the MarkLogic database, you can use the 'search' method on the database client. You need to specify a query string and specify the format of the results. Then, use the 'results' attribute to obtain the query results. For example: python query = 'John' Result_ Format='JSON '# Specify the result format as JSON results = client.search(query, result_format) for result in results: print(result) ###Data modification To modify the data in the MarkLogic database, you can use the 'new' option on the database client_ The document 'method creates a new document object and uses' add'_ The content 'method adds the content to be modified. Then, use the 'write' method to write the updated document to the database. For example: python doc = client.new_document() Doc.add_ Content ('{"name": "John Doe", "age": 35} ') # Update content doc_uri = '/people/john.json' client.write(doc, doc_uri) ###Data deletion To delete data from the MarkLogic database, you can use the 'delete' method on the database client. You need to specify the document URI to delete. For example: python doc_uri = '/people/john.json' client.delete(doc_uri) These are basic operations, and you can perform more advanced operations according to your needs.
