How to test whether a table exists in database?

Question

How can I test whether a table exists in a database before I execute a query? If the table doesn't exist, I want first create a default table with certain name so that I can always display something in JTable.
Thanks!

Hi,
There are tow ways :
The first one is :
- load the list of tables of the Database in a Vector for exemple by using methode DatabaseMetaData.getTables () and you can test if the table exist or not in the vector by using methode Vector.contains(Object o).
The code seems Like that :
// Loading List Of Tables
// you need to load the list of tables at the begening of
// your class
Vector listOfTables = new Vector();
try
rs = yourConnection.getMetaData().getTables();
while (rs.next())
listOfTables.addElement(rs.getString(3));
catch(SQLException exp)
// When you need to test the existance of table name
// you add this line
if(listOfTables.contains(tableName))
// your code
The second one :
try
//execute your query
catch
//Create your default JTable
I hope that my response can help you!
