public SybaseASE15Dialect()
```
    Constructs a SybaseASE15Dialect
- 方法详细资料
  - supportsCascadeDelete
```
public boolean supportsCascadeDelete()
```
    从类复制的说明: Dialect
    
    Does this dialect support cascaded delete on foreign key definitions?
    
    覆盖:
    
    supportsCascadeDelete 在类中 Dialect
    
    返回:
    
    true indicates that the dialect does support cascaded delete on foreign keys.
  - getMaxAliasLength
```
public int getMaxAliasLength()
```
    从类复制的说明: Dialect
    
    What is the maximum length Hibernate can use for generated aliases?
    The maximum here should account for the fact that Hibernate often needs to append "uniqueing" information to the end of generated aliases. That "uniqueing" information will be added to the end of a identifier generated to the length specified here; so be sure to leave some room (generally speaking 5 positions will suffice).
    
    覆盖:
    
    getMaxAliasLength 在类中 Dialect
    
    返回:
    
    The maximum length.
  - areStringComparisonsCaseInsensitive
```
public boolean areStringComparisonsCaseInsensitive()
```
    By default, Sybase string comparisons are case-insensitive.
    If the DB is configured to be case-sensitive, then this return value will be incorrect.
    Are string comparisons implicitly case insensitive.
    In other words, does [where 'XYZ' = 'xyz'] resolve to true?
    
    覆盖:
    
    areStringComparisonsCaseInsensitive 在类中 Dialect
    
    返回:
    
    True if comparisons are case insensitive.
  - getCurrentTimestampSQLFunctionName

    覆盖:
    
    getCurrentTimestampSQLFunctionName 在类中 Dialect
    
    返回:
    
    The function name.

```
    Actually Sybase does not support LOB locators at al.
    
    覆盖:
    
    supportsExpectedLobUsagePattern 在类中 Dialect
    
    返回:
    
    false.
    True if normal LOB usage patterns can be used with this driver; false if driver-specific hookiness needs to be applied.

```
public String getCrossJoinSeparator()
```
    从类复制的说明: Dialect
    
    Returns 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!
    
    覆盖:
    
    getCrossJoinSeparator 在类中 Dialect
    
    返回:
    
    The cross join separator

                             String tableName)
```
    从类复制的说明: Dialect
    
    Some dialects support an alternative means to SELECT FOR UPDATE, whereby a "lock hint" is appended to the table name in the from clause.
    contributed by Helge Schulz
    
    覆盖:

```
    从类复制的说明: Dialect
    
    Modifies the given SQL by applying the appropriate updates for the specified lock modes and key columns.
    The behavior here is that of an ANSI SQL SELECT FOR UPDATE. This method is really intended to allow dialects which do not support SELECT FOR UPDATE to achieve this in their own fashion.
    
    覆盖:
    
    applyLocksToSql 在类中 Dialect
    
    参数:

                                  throws SQLException
```
    从类复制的说明: Dialect
    
    Registers a parameter (either OUT, or the new REF_CURSOR param type available in Java 8) capable of returning ResultSet *by position*. Pre-Java 8, registering such ResultSet-returning parameters varied greatly across database and drivers; hence its inclusion as part of the Dialect contract.
    
    覆盖:
    
    registerResultSetOutParameter 在类中 Dialect
    
    参数:

    参数:
    
    ps - The callable statement.

```
public boolean isCurrentTimestampSelectStringCallable()
