    The orqacle join fragment

```
    Get the separator to use for defining cross joins when translating HQL queries.
    Typically this will be either [ cross join ] or [, ]
    Note that the spaces are important!

  - createCaseFragment
```
public CaseFragment createCaseFragment()
```
    Map case support to the Oracle DECODE function. Oracle did not add support for CASE until 9i.
    
    Overrides:
    
    createCaseFragment in class Dialect
    
    Returns:
    The oracle CASE -> DECODE fragment
  - getLimitString
```
public java.lang.String getLimitString(java.lang.String sql,
                              boolean hasOffset)
```
    Description copied from class: Dialect
    
    Apply s limit clause to the query.
    Typically dialects utilize variable limit clauses when they support limits. Thus, when building the select command we do not actually need to know the limit or the offest since we will just be using placeholders.
    Here we do still pass along whether or not an offset was specified so that dialects not supporting offsets can generate proper exceptions. In general, dialects will override one or the other of this method and Dialect.getLimitString(String, int, int).
    
    Overrides:
    
    getLimitString in class Dialect
    
    Parameters:
    sql - The query to which to apply the limit.
    hasOffset - Is the query requesting an offset?
    
    Returns:
    the modified SQL
  - getBasicSelectClauseNullString
```
public java.lang.String getBasicSelectClauseNullString(int sqlType)
```
    Allows access to the basic Dialect.getSelectClauseNullString(int) implementation...
    
    Parameters:
    sqlType - The Types mapping type code
    
    Returns:
    The appropriate select cluse fragment
  - getSelectClauseNullString
```
public java.lang.String getSelectClauseNullString(int sqlType)
```
    Description copied from class: Dialect
    
    Given a Types type code, determine an appropriate null value to use in a select clause.
    One thing to consider here is that certain databases might require proper casting for the nulls here since the select here will be part of a UNION/UNION ALL.
    
    Overrides:
    
    getSelectClauseNullString in class Dialect
    
    Parameters:
    sqlType - The Types type code.
    
    Returns:
    The appropriate select clause value fragment.
  - getCurrentTimestampSelectString

public java.lang.String getCurrentTimestampSelectString()
```
    Description copied from class: Dialect

    Returns:
    The command.
  - getCurrentTimestampSQLFunctionName
```
public java.lang.String getCurrentTimestampSQLFunctionName()
```
    Description copied from class: Dialect

    Overrides:
    
    getAddColumnString in class Dialect
    
    Returns:
    The "add column" fragment.
  - getSequenceNextValString
```
public java.lang.String getSequenceNextValString(java.lang.String sequenceName)
```
    Description copied from class: Dialect
    
    Generate the appropriate select statement to to retrieve the next value of a sequence.
    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 java.lang.String getSelectSequenceNextValString(java.lang.String sequenceName)
```
    Description copied from class: Dialect
    
    Generate the select expression fragment that will retrieve the next value of a sequence as part of another (typically DML) statement.
    This differs from Dialect.getSequenceNextValString(String) in that this should return an expression usable within another statement.
    
    Overrides:
    
    getSelectSequenceNextValString in class Dialect
    
    Parameters:
    sequenceName - the name of the sequence

  - getCreateSequenceString
```
public java.lang.String getCreateSequenceString(java.lang.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:
    
    getCreateSequenceString in class Dialect
    
    Parameters:
    sequenceName - The name of the sequence
    
    Returns:
    The sequence creation command
  - getDropSequenceString
```
public java.lang.String getDropSequenceString(java.lang.String sequenceName)
```
    Description copied from class: Dialect
    
    Typically dialects which support sequences can drop a sequence with a single command. This is convenience form of Dialect.getDropSequenceStrings(java.lang.String) to help facilitate that.
    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
    
    Returns:
    The sequence drop commands
  - getCascadeConstraintsString

    Overrides:
    
    dropConstraints in class Dialect
    
    Returns:
    True if constraints must be dropped prior to dropping the table; false otherwise.

    Does this dialect support sequences?
    
    Overrides:
    
    supportsSequences in class Dialect
    
    Returns:
    True if sequences supported; false otherwise.
  - supportsPooledSequences
```
public boolean supportsPooledSequences()
```
    Description copied from class: Dialect

    Overrides:
    
    supportsPooledSequences in class Dialect
    
    Returns:

  - getForUpdateNowaitString
```
public java.lang.String getForUpdateNowaitString(java.lang.String aliases)

  - bindLimitParametersInReverseOrder
```
public boolean bindLimitParametersInReverseOrder()
```
    Description copied from class: Dialect
    
    ANSI SQL defines the LIMIT clause to be in the form LIMIT offset, limit. Does this dialect require us to bind the parameters in reverse order?
    
    Overrides:
    
    bindLimitParametersInReverseOrder in class Dialect
    
    Returns:
    true if the correct order is limit, offset
  - useMaxForLimit
```
public boolean useMaxForLimit()
```
    Description copied from class: Dialect
    
    Does the LIMIT clause take a "maximum" row number instead of a total number of returned rows?
    This is easiest understood via an example. Consider you have a table with 20 rows, but you only want to retrieve rows number 11 through 20. Generally, a limit with offset would say that the offset = 11 and the limit = 10 (we only want 10 rows at a time); this is specifying the total number of returned rows. Some dialects require that we instead specify offset = 11 and limit = 20, where 20 is the "last" row we want relative to offset (i.e. total number of rows = 20 - 11 = 9)
    So essentially, is limit relative from offset? Or is limit absolute?
    
    Overrides:
    
    useMaxForLimit in class Dialect
    
    Returns:
    True if limit is relative from offset; false otherwise.
  - forUpdateOfColumns
```
public boolean forUpdateOfColumns()
```
    Description copied from class: Dialect
    
    Is FOR UPDATE OF syntax supported?
    
    Overrides:
    
    forUpdateOfColumns in class Dialect
    
    Returns:
    True if the database supports FOR UPDATE OF syntax; false otherwise.
  - getQuerySequencesString
```
public java.lang.String getQuerySequencesString()
```
    Description copied from class: Dialect
    
    Get the select command used retrieve the names of all sequences.
    
    Overrides:
    
    getQuerySequencesString in class Dialect
