public SqlTypeDescriptor getSqlTypeDescriptorOverride(int sqlCode)
```
    Description copied from class: Dialect
    
    Returns the SqlTypeDescriptor that should be used to handle the given JDBC type code. Returns null if there is no override.
    
    Overrides:
    
    getSqlTypeDescriptorOverride in class Dialect
    
    Parameters:
    
    sqlCode - A Types constant indicating the SQL column type

    getAddColumnString in class Dialect
    
    Returns:
    
    The "add column" fragment.
  - getSequenceNextValString
```
public String getSequenceNextValString(String sequenceName)
```
    Description copied from class: Dialect
    
    Generate the appropriate select statement to to retrieve the next value of a sequence.
    This should be a "stand alone" select statement.
    
    Overrides:

  - getCreateSequenceString
```
public String getCreateSequenceString(String sequenceName)
```
    Description copied from class: Dialect
    
    Typically dialects which support sequences can create a sequence with a single command. This is convenience form of Dialect.getCreateSequenceStrings(java.lang.String) to help facilitate that.
    Dialects which support sequences and can create a sequence in a single command need *only* override this method. Dialects which support sequences but require multiple commands to create a sequence should instead override Dialect.getCreateSequenceStrings(java.lang.String).
    
    Overrides:
    
    getCreateSequenceString in class Dialect
    
    Parameters:
    
    sequenceName - The name of the sequence
    
    Returns:
    
    The sequence creation command

  - dropConstraints
```
public boolean dropConstraints()
```
    Description copied from class: Dialect
    
    Do we need to drop constraints before dropping tables in this dialect?
    
    Overrides:
    
    dropConstraints in class Dialect
    
    Returns:
    
    True if constraints must be dropped prior to dropping the table; false otherwise.
  - supportsSequences
```
public boolean supportsSequences()
```
    Description copied from class: Dialect
    
    Does this dialect support sequences?
    
    Overrides:

    SchemaUpdate
  - getLimitHandler
```
public LimitHandler getLimitHandler()
```
    Description copied from class: Dialect
    
    Returns the delegate managing LIMIT clause.
    
    Overrides:
    
    getLimitHandler in class Dialect
    
    Returns:
    
    LIMIT clause delegate.
  - 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.
  - getLimitString
```
public String getLimitString(String sql,
                             boolean hasOffset)
```
    Description copied from class: Dialect
    
    Apply a limit clause to the query.
    Typically dialects utilize variable limit clauses when they support limits. Thus, when building the select command we do not actually need to know the limit or the offset since we will just be using placeholders.
    Here we do still pass along whether or not an offset was specified so that dialects not supporting offsets can generate proper exceptions. In general, dialects will override one or the other of this method and Dialect.getLimitString(String, int, int).
    
    Overrides:
    
    getLimitString in class Dialect
    
    Parameters:
    
    sql - The query to which to apply the limit.
    
    hasOffset - Is the query requesting an offset?
    
    Returns:
    
    the modified SQL
  - bindLimitParametersInReverseOrder
```
public boolean bindLimitParametersInReverseOrder()
```
    Description copied from class: Dialect
    
    ANSI SQL defines the LIMIT clause to be in the form LIMIT offset, limit. Does this dialect require us to bind the parameters in reverse order?
    
    Overrides:
    
    bindLimitParametersInReverseOrder in class Dialect
    
    Returns:
    
    true if the correct order is limit, offset

  - 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
  - supportsPooledSequences

    Overrides:
    
    supportsPooledSequences in class Dialect
    
    Returns:
    
    True if such "pooled" sequences are supported; false otherwise.

    Overloaded form of Dialect.getCreateSequenceString(String), additionally taking the initial value and increment size to be applied to the sequence definition.
    The default definition is to suffix Dialect.getCreateSequenceString(String) with the string: " start with {initialValue} increment by {incrementSize}" where {initialValue} and {incrementSize} are replacement placeholders. Generally dialects should only need to override this method if different key phrases are used to apply the allocation information.
    
    Overrides:
    
    getCreateSequenceString in class Dialect
    
    Parameters:
    
    sequenceName - The name of the sequence
    
    initialValue - The initial value to apply to 'create sequence' statement
    
    incrementSize - The increment value to apply to 'create sequence' statement
    
    Returns:
    
    The sequence creation command
  - supportsEmptyInList
```
public boolean supportsEmptyInList()
```
    Description copied from class: Dialect
    
    Does this dialect support empty IN lists?
    For example, is [where XYZ in ()] a supported construct?
    
    Overrides:
    
    supportsEmptyInList in class Dialect
    
    Returns:
    
    True if empty in lists are supported; false otherwise.
  - supportsExpectedLobUsagePattern
```
public boolean supportsExpectedLobUsagePattern()
```
    Description copied from class: Dialect
    
    Expected LOB usage pattern is such that I can perform an insert via prepared statement with a parameter binding for a LOB value without crazy casting to JDBC driver implementation-specific classes...
    Part of the trickiness here is the fact that this is largely driver dependent. For example, Oracle (which is notoriously bad with LOB support in their drivers historically) actually does a pretty good job with LOB support as of the 10.2.x versions of their drivers...
    
    Overrides:
    
    supportsExpectedLobUsagePattern in class Dialect
    
    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.
  - supportsUnboundedLobLocatorMaterialization
```
public boolean supportsUnboundedLobLocatorMaterialization()
```
    Description copied from class: Dialect
    
    Is it supported to materialize a LOB locator outside the transaction in which it was created?
    Again, part of the trickiness here is the fact that this is largely driver dependent.
    NOTE: all database I have tested which Dialect.supportsExpectedLobUsagePattern() also support the ability to materialize a LOB outside the owning transaction...
    
    Overrides:
    
    supportsUnboundedLobLocatorMaterialization in class Dialect
    
    Returns:
    
    True if unbounded materialization is supported; false otherwise.

    Overrides:
    
    supportsRowValueConstructorSyntax in class Dialect
    
    Returns:
    
    True if this SQL dialect is known to support "row value constructor" syntax; false otherwise.

    Overrides:
    
    supportsIfExistsBeforeTableName in class Dialect
    
    Returns:
    
    true if the "if exists" can be applied before the table name

  - getDropSequenceString
```
public String getDropSequenceString(String sequenceName)
```
    Description copied from class: Dialect
    
    Typically dialects which support sequences can drop a sequence with a single command. This is convenience form of Dialect.getDropSequenceStrings(java.lang.String) to help facilitate that.
    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:
    
    getDropSequenceString in class Dialect
