    从类复制的说明: Dialect
    
    The fragment used to insert a row without specifying any column values. This is not possible on some databases.
    
    覆盖:
    
    getNoColumnsInsertString 在类中 Dialect
    
    返回:
    
    The appropriate empty values clause.
  - getLimitString
```
public String getLimitString(String querySelect,
                             int offset,
                             int limit)
```
    从类复制的说明: Dialect
    
    Given a limit and an offset, apply the limit clause to the query.
    
    覆盖:
    
    getLimitString 在类中 Dialect
    
    参数:
    
    querySelect - The query to which to apply the limit.
    
    offset - The offset of the limit
    
    limit - The limit of the limit ;)
    
    返回:
    
    The modified query statement with the limit applied.
  - getLimitHandler
```
public LimitHandler getLimitHandler()
```
    从类复制的说明: Dialect
    
    Returns the delegate managing LIMIT clause.
    
    覆盖:

  - getDefaultLimitHandler
```

```
  - supportsLimit
```
public boolean supportsLimit()
```
    从类复制的说明: Dialect
    
    Does this dialect support some form of limiting query results via a SQL clause?
    
    覆盖:
    
    supportsLimit 在类中 Dialect
    
    返回:
    
    True if this dialect supports some form of LIMIT.
  - useMaxForLimit
```
public boolean useMaxForLimit()
```
    从类复制的说明: 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?
    
    覆盖:
    
    useMaxForLimit 在类中 Dialect
    
    返回:
    
    True if limit is relative from offset; false otherwise.
  - supportsLimitOffset
```
public boolean supportsLimitOffset()
```
    从类复制的说明: Dialect
    
    Does this dialect's LIMIT support (if any) additionally support specifying an offset?
    
    覆盖:
    
    supportsLimitOffset 在类中 Dialect
    
    返回:
    
    True if the dialect supports an offset within the limit support.
  - supportsVariableLimit
```
public boolean supportsVariableLimit()
```
    从类复制的说明: Dialect
    
    Does this dialect support bind variables (i.e., prepared statement parameters) for its limit/offset?
    
    覆盖:
    
    supportsVariableLimit 在类中 Dialect
    
    返回:
    
    True if bind variables can be used; false otherwise.
  - closeQuote
```
public char closeQuote()
```
    从类复制的说明: Dialect
    
    The character specific to this dialect used to close a quoted identifier.
    
    覆盖:
    
    closeQuote 在类中 Dialect
    
    返回:
    
    The dialect's specific close quote character.
  - getCurrentSchemaCommand
```
public String getCurrentSchemaCommand()
```
    从类复制的说明: Dialect
    
    Get the SQL command used to retrieve the current schema name. Works in conjunction with Dialect.getSchemaNameResolver(), unless the return from there does not need this information. E.g., a custom impl might make use of the Java 1.7 addition of the Connection.getSchema() method
    
    覆盖:
    
    getCurrentSchemaCommand 在类中 Dialect
    
    返回:
    
    The current schema retrieval SQL
  - openQuote
```
public char openQuote()
```
    从类复制的说明: Dialect
    
    The character specific to this dialect used to begin a quoted identifier.
    
    覆盖:
    
    openQuote 在类中 Dialect
    
    返回:
    
    The dialect's specific open quote character.
  - appendLockHint
```
public String appendLockHint(LockOptions lockOptions,
                             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
    
    参数:
    
    lockOptions - The lock options to apply
    
    tableName - The name of the table to which to apply the lock hint.
    
    返回:
    
    The table with any required lock hints.
  - getCurrentTimestampSelectString
```
public String getCurrentTimestampSelectString()
```
    The current_timestamp is more accurate, but only known to be supported in SQL Server 7.0 and later and Sybase not known to support it at all
    Retrieve the command used to retrieve the current timestamp from the database.
    
    返回:
    
    The command.
  - areStringComparisonsCaseInsensitive
```
public boolean areStringComparisonsCaseInsensitive()
```
    从类复制的说明: Dialect
    
    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.
  - supportsResultSetPositionQueryMethodsOnForwardOnlyCursor
```
public boolean supportsResultSetPositionQueryMethodsOnForwardOnlyCursor()
```
    从类复制的说明: 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!
    
    覆盖:
    
    supportsResultSetPositionQueryMethodsOnForwardOnlyCursor 在类中 Dialect
    
    返回:
    
    True if methods like ResultSet.isAfterLast() and ResultSet.isBeforeFirst() are supported for forward only cursors; false otherwise.
  - supportsCircularCascadeDeleteConstraints
```
public boolean supportsCircularCascadeDeleteConstraints()
```
    从类复制的说明: Dialect
    
    Does this dialect support definition of cascade delete constraints which can cause circular chains?
    
    覆盖:
    
    supportsCircularCascadeDeleteConstraints 在类中 Dialect
    
    返回:
    
    True if circular cascade delete constraints are supported; false otherwise.
  - supportsLobValueChangePropogation
```
public boolean supportsLobValueChangePropogation()
```
    从类复制的说明: 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().
    
    覆盖:
    
    supportsLobValueChangePropogation 在类中 Dialect
    
    返回:
    
    True if the changes are propagated back to the database; false otherwise.
  - doesReadCommittedCauseWritersToBlockReaders
```
public boolean doesReadCommittedCauseWritersToBlockReaders()
```
    从类复制的说明: Dialect
    
    For the underlying database, is READ_COMMITTED isolation implemented by forcing readers to wait for write locks to be released?
    
    返回:
    
    True if writers block readers to achieve READ_COMMITTED; false otherwise.
  - doesRepeatableReadCauseReadersToBlockWriters
```
public boolean doesRepeatableReadCauseReadersToBlockWriters()
```
    从类复制的说明: Dialect
    
    For the underlying database, is REPEATABLE_READ isolation implemented by forcing writers to wait for read locks to be released?
    
    返回:
    
    True if readers block writers to achieve REPEATABLE_READ; false otherwise.

    Returns the SqlTypeDescriptor that should be used to handle the given JDBC type code. Returns null if there is no override.
    
    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.

    参数:
    
    sql - the SQL string to modify

    参数:
    
    ps - The callable statement.

```
public boolean isCurrentTimestampSelectStringCallable()
```
    从类复制的说明: Dialect
    
    Should the value returned by Dialect.getCurrentTimestampSelectString() be treated as callable. Typically this indicates that JDBC escape syntax is being used...
    
    覆盖:
