java.lang.Object

org.modeshape.connector.meta.jdbc.JdbcMetadataCollector

org.modeshape.connector.meta.jdbc.SqlServerMetadataCollector

All Implemented Interfaces:

MetadataCollector

public class SqlServerMetadataCollector
extends JdbcMetadataCollector

The Microsoft SQL Server JDBC drivers return a list of users from the DatabaseMetaData.getSchemas() method instead of the actual schemas. Unfortunately, the DatabaseMetaData.getTables(String, String, String, String[]) method actually returns schema names, so the default JdbcMetadataCollector implementation doesn't match up correctly. This class should be used when the Microsoft JDBC driver is used for database connectivity. The jTDS driver has already corrected this bug and can use the default JdbcMetadataCollector.

getSchemaNames

public List<String> getSchemaNames(Connection conn,

Description copied from interface: MetadataCollector

Return the list of schema names that currently exist in the database to which connection is connected within the named catalog. If catalogName is null, then all schema names should be returned regardless of the catalog with which they are associated. The schema names must be sorted in a manner that is stable between successive calls to this method.

Specified by:

getSchemaNames in interface MetadataCollector

Overrides:

getSchemaNames in class JdbcMetadataCollector

Parameters:

conn - the connection to the database; must not be non-null and must be open. This connection should not be closed by this method.

catalogName - the name of the catalog to which returned schemas must belong, or null if all schemas are to be returned

Returns:

An ordered list of the schemas in the database, or an empty list if no schemas exist; may not be null

Throws:

JdbcMetadataException - if the schema names cannot be retrieved
