Your Holinesses,

I'm trying to recover the name, type and precision of fields in tables stored in a MySQL database using a database handle created via DBD::mysqlPP. I tried the code:

package FieldAttribs;

use DBI;

$dbh = ( "dbi:mysqlPP:database=$database;host=$host;port=$port", $user
+name, $password, {'RaiseError'=> 1} );

$sth = $dbh->prepare( "SELECT * FROM $table" );
$sth->execute();

printf "%s %s %s", $sth->{NAME_lc}->[0], $sth->{TYPE}->[0], $sth->{PRE
+CISION}->[0];

But then I get:

Can't set DBI::st=HASH(0x370ee64)->{TYPE}: unrecognised attribute name or invalid value at C:/Perl/site/lib/DBD/mysqlPP.pm line 439.

Can't set DBI::st=HASH(0x370ee64)->{PRECISION}: unrecognised attribute name or invalid value at C:/Perl/site/lib/DBD/mysqlPP.pm line 439.

Use of uninitialized value in printf at D:\Marcos\Perl\SVN\WbMx\trunk\Auxiliary\TestmysqlPP.pl line 11.

field1

Where 'field1' is actually the name of the field. Thus, NAME seems to be only statement handle that works. If I try the same code using the driver 'dbi:ODBC:driver=Microsoft Access Driver (*.mdb, *.accdb)' targeting an Access database with an identical table, I get:

field1 4 10

Any ideas? Many thanks in advance!

In reply to DBD::mysqlPP does not support TYPE and PRECISION statement handles? by taioba
