com.j256.ormlite.db
Class OracleDatabaseType

java.lang.Object
  com.j256.ormlite.db.BaseDatabaseType
      com.j256.ormlite.db.OracleDatabaseType

All Implemented Interfaces:

DatabaseType

public class OracleDatabaseType
extends BaseDatabaseType
implements DatabaseType

Oracle database type information used to create the tables, etc..

WARNING: I have not tested this unfortunately because of a lack of access to a Oracle instance. Love to get 1-2 hours of access to an database to test/tweak this. Undoubtably is it wrong. Please contact the author if you'd like to help.

Method Detail

getDriverUrlPart

public String getDriverUrlPart()

Description copied from interface: DatabaseType

Return the part in the database URI which identifies the particular database. Usually the URI is in the form jdbc:ddd:... where ddd is the driver url part.

Specified by:

getDriverUrlPart in interface DatabaseType

getDriverClassName

public String getDriverClassName()

Description copied from interface: DatabaseType

Return the class name of the database driver.

Specified by:

getDriverClassName in interface DatabaseType

appendStringType

protected void appendStringType(StringBuilder sb,
                                FieldType fieldType,
                                int fieldWidth)

Description copied from class: BaseDatabaseType

Output the SQL type for a Java String.

Overrides:

appendStringType in class BaseDatabaseType

appendByteType

protected void appendByteType(StringBuilder sb)

Description copied from class: BaseDatabaseType

Output the SQL type for a Java byte.

Overrides:

appendByteType in class BaseDatabaseType

appendLongType

protected void appendLongType(StringBuilder sb)

Description copied from class: BaseDatabaseType

Output the SQL type for a Java long.

Overrides:

appendLongType in class BaseDatabaseType

appendObjectType

protected void appendObjectType(StringBuilder sb)

Description copied from class: BaseDatabaseType

Output the SQL type for a Java object.

Overrides:

appendObjectType in class BaseDatabaseType

configureGeneratedIdSequence

protected void configureGeneratedIdSequence(StringBuilder sb,
                                            FieldType fieldType,
                                            List<String> statementsBefore,
                                            List<String> additionalArgs,
                                            List<String> queriesAfter)

Description copied from class: BaseDatabaseType

Output the SQL necessary to configure a generated-id column. This may add to the before statements list or additional arguments later. NOTE: Only one of configureGeneratedIdSequence, configureGeneratedId, or configureId will be called.

Overrides:

configureGeneratedIdSequence in class BaseDatabaseType

configureId

protected void configureId(StringBuilder sb,
                           FieldType fieldType,
                           List<String> statementsBefore,
                           List<String> additionalArgs,
                           List<String> queriesAfter)

Description copied from class: BaseDatabaseType

Output the SQL necessary to configure an id column. This may add to the before statements list or additional arguments later. NOTE: Only one of configureGeneratedIdSequence, configureGeneratedId, or configureId will be called.

Overrides:

dropColumnArg

public void dropColumnArg(FieldType fieldType,
                          List<String> statementsBefore,
                          List<String> statementsAfter)

appendEscapedEntityName

public void appendEscapedEntityName(StringBuilder sb,
                                    String word)

Description copied from interface: DatabaseType

Add a entity-name word to the string builder wrapped in the proper characters to escape it. This avoids problems with table, column, and sequence-names being reserved words.

Specified by:

appendEscapedEntityName in interface DatabaseType

Overrides:

appendEscapedEntityName in class BaseDatabaseType

isIdSequenceNeeded

public boolean isIdSequenceNeeded()

Description copied from interface: DatabaseType

Return true if the database needs a sequence when you use generated IDs. Some databases (H2, MySQL) create them auto-magically. This also means that the database needs to query for a sequence value before the object is inserted. For old[er] versions of Postgres, for example, the JDBC call-back stuff to get the just-inserted id value does not work so we have to get the next sequence value by hand, assign it into the object, and then insert the object -- yes two SQL statements.

Specified by:

isIdSequenceNeeded in interface DatabaseType

Overrides:

isIdSequenceNeeded in class BaseDatabaseType

appendSelectNextValFromSequence

public void appendSelectNextValFromSequence(StringBuilder sb,
                                            String sequenceName)

Description copied from interface: DatabaseType

Append the SQL necessary to get the next-value from a sequence. This is only necessary if DatabaseType.isIdSequenceNeeded() is true.

Specified by:

appendSelectNextValFromSequence in interface DatabaseType

Overrides:

appendSelectNextValFromSequence in class BaseDatabaseType
