Summary: Metadata TYPE_NAME value is null for String Columns
Key: TEIID-1976
URL: https://issues.jboss.org/browse/TEIID-1976
Project: Teiid
Issue Type: Bug
Components: Common
Affects Versions: 8.0
Reporter: Mark Drilling
Assignee: Ramesh Reddy
The metadata TYPE_NAME value for string datatypes is apparently returning null. I am
running against a JBoss AS7.1Final server with Teiid 8.0Beta2.
My application (openshift web client) establishes connection from a DataSource, eg
connection = dataSource.getConnection(),
then resultSet = connection.getMetaData().getColumns();
when iterating thru the resultSet, the value for columnName="TYPE_NAME" is null
for string types. Other types seem to return a correct value.

Ramesh Reddy commented on TEIID-1976:
-------------------------------------
Mark,
I do not see "getColumns" call on the DatabaseMetadata interface. Which version
of JDBC API are you using? I tried below, and it works correctly.
{code:JAVA}
ResultSetMetaData metadata = results.getMetaData();
int columns = metadata.getColumnCount();
System.out.println("Results");
for (int row = 0; row < columns; row++) {
System.out.print(metadata.getColumnName(row+1));
System.out.print("(");
System.out.print(metadata.getColumnTypeName(row+1));
System.out.print(")");
System.out.print(",");
}
{code}

I tried below with couple different VDBs
{code:JAVA}
ResultSet results = connection.getMetaData().getColumns(null, null, null, null);
for (int row = 1; results.next(); row++) {
System.out.print(results.getString("TYPE_NAME"));
}

I did not see the behaviour you described. Please attach your VDB or test case.

You should instead use getString("COLUMN_NAME") and
getString("TYPE_NAME"), or at the least
resultSet.getMetaData().getColumnLable\(i\). We do not guarantee that the column name
will match the label since the actual query may not fetch columns with the same names as
expected by JDBC.

Ramesh Reddy resolved TEIID-1976.
---------------------------------
Resolution: Done
index stores need to use the data types defined by system store to match with uuid based
look ups. The sub-selection data types defined in the teiid map correctly with designer
data types in terms of runtime type, however they do not align with uuids or their names.
This fixes the both issues.
