  - supportsSequences
```
public boolean supportsSequences()
```
    Description copied from class: Dialect
    
    Does this dialect support sequences?
    
    Overrides:
    
    supportsSequences in class DB2Dialect
    
    Returns:
    
    True if sequences supported; false otherwise.
  - supportsLimit
```
public boolean supportsLimit()
```
    Description copied from class: Dialect
    
    Does this dialect support some form of limiting query results via a SQL clause?
    
    Overrides:
    
    supportsLimit in class DB2Dialect
    
    Returns:
    
    True if this dialect supports some form of LIMIT.
  - 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 DB2Dialect
    
    Returns:
    
    The select command; or null if sequences are not supported.

  - supportsLimitOffset
```
public boolean supportsLimitOffset()
```
    Description copied from class: Dialect
    
    Does this dialect's LIMIT support (if any) additionally support specifying an offset?
    
    Overrides:
    
    supportsLimitOffset in class Dialect
    
    Returns:
    
    True if the dialect supports an offset within the limit support.
  - 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 DB2Dialect
    
    Returns:
    
    True if limit is relative from offset; false otherwise.
  - supportsVariableLimit
```
public boolean supportsVariableLimit()
```
    Description copied from class: Dialect
    
    Does this dialect support bind variables (i.e., prepared statement parameters) for its limit/offset?
    
    Overrides:
    
    supportsVariableLimit in class DB2Dialect
    
    Returns:
    
    True if bind variables can be used; false otherwise.
  - getLimitString
```
public java.lang.String getLimitString(java.lang.String sql,
                                       int offset,
                                       int limit)
```
    Description copied from class: Dialect
    
    Given a limit and an offset, apply the limit clause to the query.
    
    Overrides:
    
    getLimitString in class DB2Dialect
    
    Parameters:
    
    sql - The query to which to apply the limit.
    
    offset - The offset of the limit
    
    limit - The limit of the limit ;)
    
    Returns:
    
    The modified query statement with the limit applied.
  - getLimitHandler
```
public LimitHandler getLimitHandler()
```
    Description copied from class: Dialect
    
    Returns the delegate managing LIMIT clause.
    
    Overrides:
    
    getLimitHandler in class DB2Dialect
    
    Returns:
    
    LIMIT clause delegate.
  - getForUpdateString
```
public java.lang.String getForUpdateString()
```
    Description copied from class: Dialect
    
    Get the string to append to SELECT statements to acquire locks for this dialect.
    
    Overrides:
    
    getForUpdateString in class DB2Dialect
    
    Returns:
    
    The appropriate FOR UPDATE clause string.
  - getIdentityColumnSupport
```
public IdentityColumnSupport getIdentityColumnSupport()
```
    Description copied from class: Dialect
    
    Get the appropriate IdentityColumnSupport
    
    Overrides:
