Method Detail

supportsRandomAccessResultSet

public boolean supportsRandomAccessResultSet(Select sel,
                                             boolean forUpdate)

Description copied from class: DBDictionary

Return false if the given select requires a forward-only result set.

Overrides:

supportsRandomAccessResultSet in class DBDictionary

appendSelectRange

protected void appendSelectRange(SQLBuffer buf,
                                 long start,
                                 long end)

Description copied from class: DBDictionary

If this dictionary can select ranges, use this method to append the range SQL.

Overrides:

appendSelectRange in class DBDictionary

getCreateSequenceSQL

public java.lang.String[] getCreateSequenceSQL(Sequence seq)

Description copied from class: DBDictionary

Return a series of SQL statements to create the given sequence. Returns CREATE SEQUENCE <sequence name>[ START WITH <start>] [ INCREMENT BY <increment>] by default.

Overrides:

getCreateSequenceSQL in class DBDictionary

getSequencesSQL

protected java.lang.String getSequencesSQL(java.lang.String schemaName,
                                           java.lang.String sequenceName)

Description copied from class: DBDictionary

Return the SQL needed to select the list of sequences.

Overrides:

getSequencesSQL in class DBDictionary

decorate

public java.sql.Connection decorate(java.sql.Connection conn)
                             throws java.sql.SQLException

Description copied from class: DBDictionary

Decorate the given connection if needed. Some databases require special handling for JDBC bugs. This implementation issues any DBDictionary.initializationSQL that has been set for the dictionary but does not decoreate the connection.

Specified by:

decorate in interface org.apache.openjpa.lib.jdbc.ConnectionDecorator

Overrides:

decorate in class DBDictionary

Throws:

java.sql.SQLException
