All known Subclasses: org.apache.ojb.broker.platforms.PlatformOracle9iImpl, org.apache.ojb.broker.platforms.PlatformWLOracle9iImpl,
| PlatformOracleImpl | | public class PlatformOracleImpl extends PlatformDefaultImpl (Code) | | This class is a concrete implementation of Platform. Provides an implementation
that works around some issues with Oracle in general and Oracle's Thin driver in particular.
Many of the database sequence specific properties can be specified using
custom attributes within the sequence-manager element.
The database sequence specific properties are generally speaking, see database user guide
for detailed description.
Implementation configuration properties:
| Property Key |
Property Values |
| sequenceStart |
DEPRECATED. Database sequence specific property.
Specifies the first sequence number to be
generated. Allowed: 1 or greater.
|
| seq.start |
Database sequence specific property.
Specifies the first sequence number to be
generated. Allowed: 1 or greater.
|
| seq.incrementBy |
Database sequence specific property.
Specifies the interval between sequence numbers.
This value can be any positive or negative
integer, but it cannot be 0.
|
| seq.maxValue |
Database sequence specific property.
Set max value for sequence numbers.
|
| seq.minValue |
Database sequence specific property.
Set min value for sequence numbers.
|
| seq.cycle |
Database sequence specific property.
If true, specifies that the sequence continues to generate
values after reaching either its maximum or minimum value.
If false, specifies that the sequence cannot generate more values after
reaching its maximum or minimum value.
|
| seq.cache |
Database sequence specific property.
Specifies how many values of the sequence Oracle
preallocates and keeps in memory for faster access.
Allowed values: 2 or greater. If set 0,
an explicite nocache expression will be set.
|
| seq.order |
Database sequence specific property.
If set true, guarantees that sequence numbers
are generated in order of request.
If false, a no order expression will be set.

| PlatformOracleImpl | | public PlatformOracleImpl()(Code) | | Default constructor.
|
| afterStatementCreate | | public void afterStatementCreate(Statement stmt) throws PlatformException(Code) | | In Oracle we set escape processing explizit 'true' after a statement was created.
|
| changePreparedStatementResultSetType | | protected void changePreparedStatementResultSetType(PreparedStatement ps)(Code) | | Attempts to modify a private member in the Oracle thin driver's resultset to allow proper
setting of large binary streams.
|
| getJoinSyntaxType | | public byte getJoinSyntaxType()(Code) | | Get join syntax type for this RDBMS - one on of the constants from JoinSyntaxType interface
|
| initOracleReflectedVars | | protected void initOracleReflectedVars()(Code) | | Initializes static variables needed for getting Oracle-specific JDBC types.
|
| isUsingOracleThinDriver | | protected static boolean isUsingOracleThinDriver(Connection conn)(Code) | | Checks if the supplied connection is using the Oracle thin driver.
Parameters:
conn - database connection for which to check JDBC-driver true if the connection is using Oracle thin driver, falseotherwise. |
| setObjectForStatement | | public void setObjectForStatement(PreparedStatement ps, int index, Object value, int sqlType) throws SQLException(Code) | | For objects beyond 4k, weird things happen in Oracle if you try to use "setBytes", so for
all cases it's better to use setBinaryStream. Oracle also requires a change in the resultset
type of the prepared statement. MBAIRD NOTE: BLOBS may not work with Oracle database/thin
driver versions prior to 8.1.6.
