Hi,
I noticed that getTypeInfo() may not return data in the order specified in Oracle documentation (
https://docs.oracle.com/javase/7/docs/api/java/sql/DatabaseMetaData.html#getTypeInfo()): Retrieves a description of all the data types supported by this database. They are ordered by DATA_TYPE and then by how closely the data type maps to the corresponding JDBC SQL type.
With the following code snippet:
try (Connection connection = dataSource.getConnection(); ResultSet rs = connection.getMetaData().getTypeInfo()) {
while (rs.next()) {
System.out.println(rs.getInt("DATA_TYPE"));
}
} catch (SQLException e) {}
I am getting DATA_TYPE in a non-monotonic order:
-7
-2
1
12
-5
...
Additional metadata:
JDBC driver: PostgreSQL 9.4.1212
Server version: 9.6beta1.0 (9.6beta1.0)
What do I do wrong?
Best regards,
Jan Motl
