getTables is this right?

Hi,

I am having problems getting info on tables with getTables. I get null
returned all of the time.

I looked at this url, which I don't know if it is very recent or not.

http://www.postgresql.org/docs/pgsql/src/interfaces/jdbc/org/postgresql/jdbc
2/DatabaseMetaData.java

public java.sql.ResultSet getTables(String catalog, String schemaPattern,
String tableNamePattern, String types[]) throws SQLException
{
// Handle default value for types
if(types==null)
types = defaultTableTypes;

if(tableNamePattern==null)
tableNamePattern="%";

// the field descriptors for the new ResultSet
Field f[] = new Field[5];
java.sql.ResultSet r; // ResultSet for the SQL query that we need
to do
Vector v = new Vector(); // The new ResultSet tuple stuff

f[0] = new Field(connection, "TABLE_CAT", iVarcharOid, 32);
f[1] = new Field(connection, "TABLE_SCHEM", iVarcharOid, 32);
f[2] = new Field(connection, "TABLE_NAME", iVarcharOid, 32);
f[3] = new Field(connection, "TABLE_TYPE", iVarcharOid, 32);
f[4] = new Field(connection, "REMARKS", iVarcharOid, 32);

I was using this code

snip:

//String [] onlytables = new String[3];
//onlytables[0] = "TABLE";
//onlytables[1] = "INDEX";
ResultSet tableRS =
m_inputCon.getMetaData().getTables(null,null,"%",null);

/* I had used the String [] onlytables in place of null, but I got

java.sql.SQLException: ERROR: parser: parse error at or near ")"

while (tableRS.next())

{


String tableType = tableRS.getString(4); // make sure that
this is a table and not an index.
.
System.out.println("TABLE TYPE IS: "+tableType);
if ( tableType.compareTo( "TABLE") !=0 ) {

tableRS.next();
}



String onetable = tableRS.getString(3); // table name int is
faster that "TABLE_NAME"


snip:

Now when I read the JDBC API It says that the TABLE_NAME is column 3 and
TABLE_TYPE should be column 4 in the getTables ResultSet.
It looks to me like that is messed up with.

f[2] = new Field(connection, "TABLE_NAME", iVarcharOid, 32);
f[3] = new Field(connection, "TABLE_TYPE", iVarcharOid, 32);

I may be way off here, in my guessing, but I can't get getTables table type
to return a type.

I am using the 7.0 driver with the jar named 7.0-1.2.jar and Postgress 7.0.3
on the server end.

I hope I didn't get my versions messed up, but that is the other thing I am
not certain about, what is the latest version of the driver and is it
nessicarly in the current "latest" postgress download?

Thanks,

Eric
