public class TimesTenDialect
extends Dialect
```
A SQL dialect for TimesTen 5.1. Known limitations: joined-subclass support because of no CASE support in TimesTen No support for subqueries that includes aggregation - size() in HQL not supported - user queries that does subqueries with aggregation No CLOB/BLOB support No cascade delete support. No Calendar support No support for updating primary keys.

```
    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.

  - getCreateSequenceString
```
public String getCreateSequenceString(String sequenceName)
```
    Description copied from class: Dialect

    Parameters:
    sequenceName - The name of the sequence
    
    Returns:
    The sequence creation command
  - getDropSequenceString

    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:

    Description copied from class: Dialect
    
    Does this dialect support column-level check constraints?
    
    Overrides:
    
    supportsColumnCheck in class Dialect

    True if table-level CHECK constraints are supported; false otherwise.
  - 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.
  - 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 Dialect
    
    Returns:
    True if bind variables can be used; 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 Dialect
    
    Returns:
    True if this dialect supports some form of LIMIT.
  - 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.
  - getLimitString

                    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 Dialect
    
    Parameters:
    querySelect - 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.
