From 60553337d72f73d663f46d0e6a62e8c81077b322 Mon Sep 17 00:00:00 2001 From: Bruce Momjian Date: Thu, 4 Oct 2001 15:46:49 +0000 Subject: [PATCH] Attached is a patch which deals with select 'id' as xxx from table The issue is: When the driver gets a data type which does not map into the SQL.Types it attempts to load the object into a java object. Eventually throwing an exception indicating that the type "unknown" was not found. Since the backend defaults "unknown" types to text it was suggested that the jdbc driver do the same. This patch does just that. I have tested it on the above select statement as well as a small program that serializes, and deserializes a class Dave Cramer --- src/interfaces/jdbc/org/postgresql/jdbc1/ResultSet.java | 8 +++++++- src/interfaces/jdbc/org/postgresql/jdbc2/ResultSet.java | 8 +++++++- 2 files changed, 14 insertions(+), 2 deletions(-) diff --git a/src/interfaces/jdbc/org/postgresql/jdbc1/ResultSet.java b/src/interfaces/jdbc/org/postgresql/jdbc1/ResultSet.java index 8949eabc75..eecce9c939 100644 --- a/src/interfaces/jdbc/org/postgresql/jdbc1/ResultSet.java +++ b/src/interfaces/jdbc/org/postgresql/jdbc1/ResultSet.java @@ -862,7 +862,13 @@ public class ResultSet extends org.postgresql.ResultSet implements java.sql.Resu case Types.VARBINARY: return getBytes(columnIndex); default: - return connection.getObject(field.getPGType(), getString(columnIndex)); + String type = field.getPGType(); + // if the backend doesn't know the type then coerce to String + if (type.equals("unknown")){ + return getString(columnIndex); + }else{ + return connection.getObject(field.getPGType(), getString(columnIndex)); + } } } diff --git a/src/interfaces/jdbc/org/postgresql/jdbc2/ResultSet.java b/src/interfaces/jdbc/org/postgresql/jdbc2/ResultSet.java index 9df669910d..feec8d08c2 100644 --- a/src/interfaces/jdbc/org/postgresql/jdbc2/ResultSet.java +++ b/src/interfaces/jdbc/org/postgresql/jdbc2/ResultSet.java @@ -727,7 +727,13 @@ public class ResultSet extends org.postgresql.ResultSet implements java.sql.Resu case Types.VARBINARY: return getBytes(columnIndex); default: - return connection.getObject(field.getPGType(), getString(columnIndex)); + String type = field.getPGType(); + // if the backend doesn't know the type then coerce to String + if (type.equals("unknown")){ + return getString(columnIndex); + }else{ + return connection.getObject(field.getPGType(), getString(columnIndex)); + } } }
