metadata on a table

[Malm Paul <paul.malm@xxxxxxxxxxxxx>]

Hi,

I'm trying to read the metadata from table to create the same sort of table in another database, using java.

 

This is how I do it today

quwstion = "SELECT  * FROM table"
stmnt = dbConnection.prepareStatement(question);

rs = stmnt.executeQuery();

ResultSetMetaData rsMetaData = rs.getMetaData();
int numberOfColumns = rsMetaData.getColumnCount();
System.out.println("resultSet MetaData column Count=" + numberOfColumns);
int precision = rsMetaData.getPrecision(1);
String columnTypeName = rsMetaData.getColumnTypeName(1);
String name = rsMetaData.getColumnName(1);
String classname = rsMetaData.getColumnClassName(1);

The first object is the primary key with the name "fid",

columnTypeName = int4

 

I can see in the original table that fid has the type serial, which is an int4 (pgAdmin).

But when I create the table in the other database I would like to create it as serial not just int4, how can I know that it is a serial? 

 

Kind regards,

Paul
