public VirtuosoAdapter(DatabaseMetaData metadata)

Method Details

newSQLTypeInfo

public SQLTypeInfo newSQLTypeInfo(ResultSet rs)

Description copied from interface: DatastoreAdapter

Create a new SQL type info from the current row of the passed ResultSet. Allows an adapter to override particular types where the JDBC driver is known to be buggy.

Specified by:

newSQLTypeInfo in interface DatastoreAdapter

Overrides:

newSQLTypeInfo in class BaseDatastoreAdapter

Parameters:

rs - ResultSet

Returns:

The SQL type info

getVendorID

public String getVendorID()

Description copied from interface: DatastoreAdapter

Accessor for the Vendor ID for this datastore.

Specified by:

getVendorID in interface DatastoreAdapter

Overrides:

getVendorID in class BaseDatastoreAdapter

Returns:

Vendor id for this datastore

getAddPrimaryKeyStatement

public String getAddPrimaryKeyStatement(PrimaryKey pk,
 IdentifierFactory factory)

MySQL, when using AUTO_INCREMENT, requires the primary key specified in the CREATE TABLE, so we do nothing here.

Specified by:

getAddPrimaryKeyStatement in interface DatastoreAdapter

Overrides:

getAddPrimaryKeyStatement in class BaseDatastoreAdapter

Parameters:

pk - An object describing the primary key.

factory - Identifier factory

Returns:

The PK statement

getDropTableStatement

public String getDropTableStatement(Table table)

Method to return the DROP TABLE statement. Override the default omitting the CASCADE part since Virtuoso doesn't support that.

Specified by:

getDropTableStatement in interface DatastoreAdapter

Overrides:

getDropTableStatement in class BaseDatastoreAdapter

Parameters:

table - The table

Returns:

The drop statement

getExistingIndexes

public ResultSet getExistingIndexes(Connection conn,
 String catalog,
 String schema,
 String table)
                             throws SQLException

Specified by:

getExistingIndexes in interface DatastoreAdapter

Overrides:

getExistingIndexes in class BaseDatastoreAdapter

Parameters:

conn - the JDBC connection

catalog - the catalog name

schema - the schema name.

table - the table name

Returns:

a ResultSet with the format @see DatabaseMetaData#getIndexInfo(java.lang.String, java.lang.String, java.lang.String, boolean, boolean)

Throws:

SQLException - if an error occurs

getIdentityLastValueStmt

public String getIdentityLastValueStmt(Table table,
 String columnName)

Accessor for the auto-increment sql statement for this datastore.

Specified by:

getIdentityLastValueStmt in interface DatastoreAdapter

Overrides:

getIdentityLastValueStmt in class BaseDatastoreAdapter

Parameters:

table - Name of the table that the autoincrement is for

columnName - Name of the column that the autoincrement is for

Returns:

The statement for getting the latest auto-increment key

getIdentityKeyword

public String getIdentityKeyword(org.datanucleus.store.StoreManager storeMgr)
