Welcome to SchemaSpy. We will do the best to simplify documentation process of your database.
Parameters can be specified in the comand line (described below) or you can predefine configuration in the file.
SchemaSpy will search configuration file in
To use an alternative configuration file run SchemaSpy with parameter:
java -jar schemaspy.jar -configFile path/to/config.file
Config file example:
# type of database. Run with -dbhelp for details schemaspy.t=mssql # optional path to alternative jdbc drivers. schemaspy.dp=path/to/drivers # database properties: host, port number, name user, password schemaspy.host=server schemaspy.port=1433 schemaspy.db=db_name schemaspy.u=database_user schemaspy.p=database_password # output dir to save generated files schemaspy.o=path/to/output # db scheme for which generate diagrams schemaspy.s=dbo
You can easily run SchemaSpy from the command line:
java -jar schemaspy.jar -t dbType -dp C:/sqljdbc4-3.0.jar -db dbName -host server -port 1433 [-s schema] -u user [-p password] -o outputDir
It is important to notice, that command-line parameters override those configured in schemaspy.properties file.
Commonly used parameters:¶
- [-t databaseType]
- Type of database (e.g. ora, db2, etc.). Use -dbhelp for a list of built-in types. Defaults to ora.
- [-db dbName]
- Name of database to connect to
- [-u user]
- Valid database user id with read access. A user id is required unless -sso is specified.
- [-s schema]
- Database schema. This is optional if it’s the same as user or isn’t supported by your database. Use -noschema if your database thinks it supports schemas but doesn’t (e.g. older versions of Informix).
- [-p password]
- Password associated with that user. Defaults to no password.
- [-o outputDirectory]
- Directory to write the generated HTML/graphs to
- [-dp pathToDrivers]
- Looks for drivers here before looking in driverPath in [databaseType].properties. The drivers are usually contained in .jar or .zip files and are typically provided by your database vendor.
- [-hq] or [-lq]
- Generate higher or lower-quality diagrams. Various installations of Graphviz (depending on OS and/or version) will default to generat /ing either higher or lower quality images. That is, some might not have the “lower quality” libraries and others might not have the “higher quality” libraries. Higher quality output takes longer to generate and results in significantly larger image files (which take longer to download / display), but the resultant Entity Relationship diagrams generally look better.
