Error message is very clear. And MySQL does not support custom data types.

Currently MySQL is supporting only:

1. Numeric Type
2. Date and Time Type
3. String Type

Or, you can use each of the input values as a set of values of IN function in MySQL.

Change your JAVA code as follows:

StringBuilder sbSql = new StringBuilder( 1024 );
sbSql.append( "select * from userinfo where firstname in(" );

for( int i=0; i < Parameter.length; i++ ) {
  if( i > 0 ) sbSql.append( "," );
  sbSql.append( " ?" );
} // for
sbSql.append( " )" );
PreparedStatement pst = conn.prepareStatement( sbSql.toString() );

for( int i=0; i < Parameter.length; i++ ) {
  pst.setString( i+1, Parameter[ i ] );
} // for

ResultSet rs = pst.executeQuery();
