    Constructs a SybaseASE157Dialect
- Method Detail
  - getTableTypeString
```
public String getTableTypeString()
```
    Overrides:
    
    getTableTypeString in class Dialect
  - supportsExpectedLobUsagePattern
```
public boolean supportsExpectedLobUsagePattern()
```
    Description copied from class: SybaseASE15Dialect
    
    Actually Sybase does not support LOB locators at al.
    
    Overrides:
    
    supportsExpectedLobUsagePattern in class SybaseASE15Dialect
    
    Returns:

    True if normal LOB usage patterns can be used with this driver; false if driver-specific hookiness needs to be applied.
  - supportsLobValueChangePropogation
```
public boolean supportsLobValueChangePropogation()
```
    Description copied from class: Dialect
    
    Does the dialect support propagating changes to LOB values back to the database? Talking about mutating the internal value of the locator as opposed to supplying a new locator instance...
    For BLOBs, the internal value might be changed by: Blob.setBinaryStream(long), Blob.setBytes(long, byte[]), Blob.setBytes(long, byte[], int, int), or Blob.truncate(long).
    For CLOBs, the internal value might be changed by: Clob.setAsciiStream(long), Clob.setCharacterStream(long), Clob.setString(long, String), Clob.setString(long, String, int, int), or Clob.truncate(long).
    NOTE : I do not know the correct answer currently for databases which (1) are not part of the cruise control process or (2) do not Dialect.supportsExpectedLobUsagePattern().
    
    Overrides:
    
    supportsLobValueChangePropogation in class Dialect
    
    Returns:
    
    True if the changes are propagated back to the database; 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.
  - getForUpdateString
```
public String getForUpdateString()
```
    Description copied from class: Dialect
    
    Get the string to append to SELECT statements to acquire locks for this dialect.
    
    Returns:

```
    Description copied from class: Dialect
    
    Get the FOR UPDATE OF column_list fragment appropriate for this dialect given the aliases of the columns to be write locked.
    
    Overrides:
    
    getForUpdateString in class Dialect
    
    Parameters:
    
    aliases - The columns to be write locked.
    
    Returns:
    
    The appropriate FOR UPDATE OF column_list clause string.
  - appendLockHint
```
public String appendLockHint(LockOptions mode,
                             String tableName)
```
    Description copied from class: 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
    
    Parameters:
    
    mode - The lock options to apply
    
    tableName - The name of the table to which to apply the lock hint.
    
    Returns:
    
    The table with any required lock hints.
  - applyLocksToSql
```
public String applyLocksToSql(String sql,
                              LockOptions aliasedLockOptions,
                              Map<String,String[]> keyColumnNames)
```
    Description copied from class: 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.
    
    Parameters:
    
    sql - the SQL string to modify
    
    aliasedLockOptions - lock options indexed by aliased table names.
    
    keyColumnNames - a map of key columns indexed by aliased table names.
    
    Returns:
    
    the modified SQL string.
  - buildSQLExceptionConversionDelegate
```
public SQLExceptionConversionDelegate buildSQLExceptionConversionDelegate()
```
    Description copied from class: Dialect
    Build an instance of a SQLExceptionConversionDelegate for interpreting dialect-specific error or SQLState codes.
    When Dialect.buildSQLExceptionConverter() returns null, the default SQLExceptionConverter is used to interpret SQLState and error codes. If this method is overridden to return a non-null value, the default SQLExceptionConverter will use the returned SQLExceptionConversionDelegate in addition to the following standard delegates:
    1. a "static" delegate based on the JDBC 4 defined SQLException hierarchy;
    2. a delegate that interprets SQLState codes for either X/Open or SQL-2003 codes, depending on java.sql.DatabaseMetaData#getSQLStateType
    It is strongly recommended that specific Dialect implementations override this method, since interpretation of a SQL error is much more accurate when based on the vendor-specific ErrorCode rather than the SQLState.
    Specific Dialects may override to return whatever is most appropriate for that vendor.
    Overrides:
    
    buildSQLExceptionConversionDelegate in class Dialect
    
    Returns:
    
    The SQLExceptionConversionDelegate for this dialect

    Returns:
    
    True if this dialect supports some form of LIMIT.
  - 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.
  - getLimitHandler
```
public LimitHandler getLimitHandler()
```
    Description copied from class: Dialect
    
    Returns the delegate managing LIMIT clause.
    
    Overrides:

```
    Description copied from class: Dialect

    The "add column" fragment.
