public SQLServerDialect()
```
- Method Detail
  - getNoColumnsInsertString
```
public String getNoColumnsInsertString()
```
    Description copied from class: Dialect
    
    The fragment used to insert a row without specifying any column values. This is not possible on some databases.
    
    Overrides:
    
    getNoColumnsInsertString in class Dialect
    
    Returns:
    The appropriate empty values clause.
  - getLimitString
```
public String getLimitString(String querySelect,
                    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.
  - appendIdentitySelectToInsert
```
public String appendIdentitySelectToInsert(String insertSQL)
```
    Use insert table(...) values(...) select SCOPE_IDENTITY()
    
    Parameters:
    insertSQL - The insert command
    
    Returns:
    The insert command with any necessary identity select clause attached.
  - 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.
  - 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.
  - closeQuote
```
public char closeQuote()
```
    Description copied from class: Dialect
    
    The character specific to this dialect used to close a quoted identifier.
    
    Overrides:
    
    closeQuote in class Dialect
    
    Returns:
    The dialect's specific close quote character.
  - openQuote
```
public char openQuote()
```
    Description copied from class: Dialect
    
    The character specific to this dialect used to begin a quoted identifier.
    
    Overrides:
    
    openQuote in class Dialect
    
    Returns:
    The dialect's specific open quote character.
  - appendLockHint
```
public String appendLockHint(LockOptions lockOptions,
                    String tableName)
```
    Description copied from class: Dialect
    
    Some dialects support an alternative means to SELECT FOR UPDATE, whereby a "lock hint" is appends to the table name in the from clause.
    contributed by Helge Schulz
    
    Parameters:
    lockOptions - 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.
  - getCurrentTimestampSelectString
```
public String getCurrentTimestampSelectString()
```
    Description copied from class: Dialect
    
    Retrieve the command used to retrieve the current timestamp from the database.
    
    Returns:
    The command.
  - areStringComparisonsCaseInsensitive
```
public boolean areStringComparisonsCaseInsensitive()
```
    Description copied from class: Dialect
    
    Are string comparisons implicitly case insensitive.
    In other words, does [where 'XYZ' = 'xyz'] resolve to true?
    
    Overrides:
    
    areStringComparisonsCaseInsensitive in class Dialect
    
    Returns:
    True if comparisons are case insensitive.
  - supportsResultSetPositionQueryMethodsOnForwardOnlyCursor
```
public boolean supportsResultSetPositionQueryMethodsOnForwardOnlyCursor()
```
    Description copied from class: Dialect
    
    Does this dialect support asking the result set its positioning information on forward only cursors. Specifically, in the case of scrolling fetches, Hibernate needs to use ResultSet.isAfterLast() and ResultSet.isBeforeFirst(). Certain drivers do not allow access to these methods for forward only cursors.
    NOTE : this is highly driver dependent!
    
    Overrides:
    
    supportsResultSetPositionQueryMethodsOnForwardOnlyCursor in class Dialect
    
    Returns:
    True if methods like ResultSet.isAfterLast() and ResultSet.isBeforeFirst() are supported for forward only cursors; false otherwise.

    Overrides:
    
    supportsCircularCascadeDeleteConstraints in class Dialect
    
    Returns:
    True if circular cascade delete constraints are supported; false otherwise.
  - 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.

```
    Description copied from class: Dialect
    
    For the underlying database, is REPEATABLE_READ isolation implemented by forcing writers to wait for read locks to be released?
    
    Returns:
    True if readers block writers to achieve REPEATABLE_READ; false otherwise.
  - getSqlTypeDescriptorOverride
```
protected SqlTypeDescriptor getSqlTypeDescriptorOverride(int sqlCode)
```
    Returns the SqlTypeDescriptor that should be used to handle the given JDBC type code. Returns null if there is no override.

    getSqlTypeDescriptorOverride in class Dialect
    
    Parameters:
    sqlCode - A Types constant indicating the SQL column type

```
    Description copied from class: Dialect
