Generate ER diagram from postgresql database [SchemaSpy]

StackOverflow https://stackoverflow.com/questions/16399078

Question

Anyone use this tool? I wanted to generate a ER diagram from my database. I run SchemaSpy like this:

java -jar schemaSpy_5.0.0.jar -t pgsql -db mydb -host localhost -dp /home/katie/downloads/postgresql-8.0-312.jdbc3.jar -noschema -u postgres -o .

and then, I got errors:

Using database properties:
  [schemaSpy_5.0.0.

    jar]/net/sourceforge/schemaspy/dbTypes/pgsql.properties

I use PostgreSQL 9.1 on Xubuntu 12.04.

Was it helpful?

Solution

Issues were resolved by:

  • Using a PgJDBC contemporary to the PostgreSQL 9.1 database install, instead of trying to use PgJDBC 8.0; and
  • Using the JDBC3 driver, as SchemaSpy didn't seem to like the JDBC4 driver.

OTHER TIPS

java -jar F:/schema/schemaSpy_5.0.0.jar -t postgresql -db dhis2ccem1 -host localhost -port 5432 -s public -u postgres -p root -dp F:/schema/postgresql-9.0-801.jdbc4.jar -o output
