DBDatabaseDriverDerby()
Constructor for the Derby database driver.
|
Modifier and Type | Method and Description |
---|---|
DBCommand |
createCommand(DBDatabase db)
Creates a new Derby command object.
|
String |
getConvertPhrase(DataType destType,
DataType srcType,
Object format)
Returns a data type convertion phrase template for this driver
The returned template must contain a '?' which will be replaced by a column expression. |
String |
getDatabaseName()
returns the name for the database / schema
|
void |
getDDLScript(DBCmdType type,
DBObject dbo,
DBSQLScript script)
Appends the required DLL commands to create, drop or alter an object to the supplied DBDQLScript.
|
Object |
getNextSequenceValue(DBDatabase db,
String seqName,
int minValue,
Connection conn)
Returns the next value of a named sequence The numbers are used for fields of type DBExpr.DT_AUTOINC.
If a driver supports this function it must return true for isSupported(DBDriverFeature.SEQUENCES). |
String |
getSequenceTableName()
returns the name of the sequence table
|
String |
getSQLPhrase(int phrase)
Gets an sql phrase template for this database system.
|
Timestamp |
getUpdateTimestamp(Connection conn)
Overridden.
|
boolean |
isSupported(DBDriverFeature type)
Returns whether or not a particular feature is supported by this driver
|
boolean |
isUseSequenceTable()
returns whether a sequence table is used for record identiy management.
Default is false. |
void |
setDatabaseName(String databaseName)
Sets the name for the database / schema
This names is required for creating a database. When a name is set, the driver will automatically execute 'USE dbname' when the database is opened. |
void |
setSequenceTableName(String sequenceTableName)
Sets the name of the sequence table.
|
void |
setUseSequenceTable(boolean useSequenceTable)
If set to true a special table is used for sequence number generation.
Otherwise the AutoIncrement feature of Derby is used identiy fields. |
