Hi, i wanted to use a String to change my request to my DB.
Means i use a String called "search" for example.
So i could go search= "search1";
( "SELECT * FROM table WHERE x="search" ");

But it doesnt works.

However, if i put my request directly on my
("SELECT * FROM table WHERE x="search1"")
It works, indeed.

So i dont understand how to use a String (that i could change) to do my request to my DB.

Thanks for your help !

=> Sorry for my bad english, if you know what i mean :)

Create a class inspector that will generate SQL code that is needed to store class in a DB:

mydb.execute( mydb.tableFor( MyFunkyClass.class ) );

For example:

• http://www.hibernate.org/
• http://sourceforge.net/projects/crossdb/

Mainly for SQLite, add method to generate db.sqlite at given path or in sketch folder:

mySqlDb.createDatabase("name.sqlite");
mySqlDb.createDatabase("/full/path/to/my/folder/name.sqlite");

Smarter queries:

db.query( String )
db.query( String, Object ... args ) {
db.query( String.format( String, args ) )
}

or just use a [PreparedStatement](http://docs.oracle.com/javase/6/docs/api/java/sql/PreparedStatement.html PreparedStatement) which seems to bring in

select("table_name").all()
select("table_name").where("name",Object).groupBy("foo")

Hello,

I wish to populate an array with the query result, and the normal way is with resultSet rs = pgsql.query(query); however I get the message 'cannot convert from void to resultset' even when importing additional libraries.
import de.bezier.data.sql.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
String user = "postgres";
String pass = "a";
String database = "wordnet30";
ArrayList <String[]> result = new ArrayList<String[]>();

PostgreSQL pgsql;
pgsql = new PostgreSQL( this, "localhost:5432", "wordnet30", "postgres", "a" );
if ( pgsql.connect() )
{
//Statement st = conn.createStatement();
ResultSet rs = pgsql.query("SELECT * FROM ra");
int columnCount = rs.getMetaData().getColumnCount();
while(pgsql.next())
{
String[] row = new String[columnCount];
for (int i = 0; i < columnCount; i++)
{
row[i] = rs.getString(i+1);
}
result.add(row);

    }
}
else
{
}
Print(result);

Is there a way around this? Is it feasible to use the JDBC directly in Processing, and avoiding 'public static void main' ?
Best regards,
Nicholas Bloom

Hi,
I posted this to The Processing Forum, Can you have a look ? I explain the problem.
http://forum.processing.org/two/discussion/comment/45968#Comment_45968
Can you help ?
Thank you for your library. It helps me a lot.

http://processing.org/reference/Table.html

Attempting to use the library in Processing 3 gives the following error:

NoSuchMethodError: You may be using a library that's incompatible with this version of Processing.

Your library has been a critical part of my workflow and it would be tragic for it to not be updated to work with P3.

thanks!

Was ist das in PostgreSQL, das geht nicht.

public String[] getTableNames ()
{
    if ( tableNames == null )
    {
        tableNames = new ArrayList<String>();
        query( "SELECT relname AS 'table_name' FROM pg_stat_user_tables WHERE schemaname='public'" );
        while ( next() ) {
            tableNames.add( getObject("table_name").toString() );
        }
    }
    return tableNames.toArray(new String[0]);
}

}

The library zip file should have the folder structure described in the library guidelines

• documentation should be reference
• source should be src

Make sure this is taken account for:
http://dev.mysql.com/doc/refman/5.1/en/connector-j-reference-charsets.html

... there have been complaints about characters not showing up correct in Processing sketches. Review these and make tests to ensure it's not on our side.
