Dbschema mongodb set primary key driver#
Download JDBC Driver Binary Distributionĭownload the driver from the DbSchema website. The collection fields can be sorted by adding sort=true in the URL.Ĭode modifications allowed only to the current repository as pull requests The number of scanned documents can be set in the URL using the parameter scan=.
Scanning random documents from each collection. We presume that collections are storing similar documents, so we 'deduce' a virtual schema by To be able to execute native MongoDb queries we embedded an Rhino JavaScript engine inside the driver.Įach time you execute a query we parse and run it as JavaScript with Rhino.Ĭalling methods from the DatabaseMetaData.getTables(), getColumns(), etc., the driver willĭeduce a logical structure of the database.
This because the first document in the result may have less keys as the next records. If expand is set the driver will read ahead a number of rows in order to create a correct ResultSetMetaData. Use resultSet.getObject(1) to get this object.Īdding the parameter expand=true in the URL will create a column in the result set for each key in the result document. The driver returns by default a ResultSet with a single Object. Therefore, the JDBC URL is the same as MongoDb URL. The driver is using the native MongoDb Java driver to connect and execute queries. JDBC driver capable to execute native MongoDb queries, similar with Mongo Shell. The driver is provided by DbSchema - MongoDb Diagram Designer for everybody who needs an MongoDb JDBC driver.
