    This should be a "stand alone" select statement.
    
    Overrides:
    
    getSequenceNextValString in class Dialect
    
    Parameters:
    
    sequenceName - the name of the sequence
    
    Returns:
    
    String The "nextval" select string.
  - getSelectSequenceNextValString
```
public String getSelectSequenceNextValString(String sequenceName)

  - getCreateSequenceString
```
public String getCreateSequenceString(String sequenceName)
```
    Description copied from class: Dialect
    
    Typically dialects which support sequences can create a sequence with a single command. This is convenience form of Dialect.getCreateSequenceStrings(java.lang.String) to help facilitate that.
    Dialects which support sequences and can create a sequence in a single command need *only* override this method. Dialects which support sequences but require multiple commands to create a sequence should instead override Dialect.getCreateSequenceStrings(java.lang.String).
    
    Overrides:

    Dialects which support sequences and can drop a sequence in a single command need *only* override this method. Dialects which support sequences but require multiple commands to drop a sequence should instead override Dialect.getDropSequenceStrings(java.lang.String).
    
    Overrides:
    
    getDropSequenceString in class Dialect
    
    Parameters:
    
    sequenceName - The name of the sequence

    Overrides:
    
    createCaseFragment in class Dialect
    
    Returns:
    
    This dialect's CaseFragment strategy.

    Overrides:
    
    getDefaultMultiTableBulkIdStrategy in class Dialect
  - supportsJdbcConnectionLobCreation
```
public boolean supportsJdbcConnectionLobCreation(DatabaseMetaData databaseMetaData)
```
    Description copied from class: Dialect
    
    Check whether the JDBC Connection supports creating LOBs via Connection.createBlob(), Connection.createNClob() or Connection.createClob().
    
    Overrides:
    
    supportsJdbcConnectionLobCreation in class Dialect
    
    Parameters:
    
    databaseMetaData - JDBC DatabaseMetaData which can be used if LOB creation is supported only starting from a given Driver version
    
    Returns:
