Column names and datatypes

Use getMetadata of Connection. According to jdocs, the DatabaseMetaData
object can probably give you what you are looking for.

Subject: [GENERAL] Column names and datatypes

I need to acquire the list of all column names and datatypes from a table
through the JDBC interface using an sql command. What I want is available in
"psql" with the "\d tablename" command, but I cannot figure out how to get
these via an sql command. Can anyone help?

Thanks,

Glenn

You can either query the information_schema's tables and views, or
you can start psql with the '-E' switch and view the queries its
sending and modify them to fit your requirements.
