Constructor Detail

### InterbaseDialect

    public InterbaseDialect()

Method Detail

### getAddColumnString

    public String getAddColumnString()

  Description copied from class: `Dialect`
  The syntax used to add a column to a table (optional).

  Overrides:
    `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 retreive the next value of a sequence.

  This should be a "stand alone" select statement.

  Overrides:
    `getSequenceNextValString` in class `Dialect`
  Parameters:
    `sequenceName` - the name of the sequence
  Returns:
    String The "nextval" select string.

### getSelectSequenceNextValString

    public String getSelectSequenceNextValString(String sequenceName)

  Description copied from class: `Dialect`
  Generate the select expression fragment that will retreive the next value of a sequence as part of another (typically DML) statement.

  This differs from `Dialect.getSequenceNextValString(String)` in that this should return an expression usable within another statement.

  Overrides:
    `getSelectSequenceNextValString` in class `Dialect`
  Parameters:
    `sequenceName` - the name of the sequence
  Returns:
    The "nextval" fragment.

### 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

### 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`
  Parameters:
    `sequenceName` - The name of the sequence
  Returns:
    The sequence drop commands

### getQuerySequencesString

    public String getQuerySequencesString()

  Description copied from class: `Dialect`
  Get the select command used retrieve the names of all sequences.

  Overrides:
    `getQuerySequencesString` in class `Dialect`
  Returns:
    The select command; or null if sequences are not supported.
  See Also:
    `SchemaUpdate`

### getForUpdateString

    public String getForUpdateString()

  Description copied from class: `Dialect`
  Get the string to append to SELECT statements to acquire locks for this dialect.

  Overrides:
    `getForUpdateString` in class `Dialect`
  Returns:
    The appropriate `FOR UPDATE` clause string.

### getForUpdateString

    public String getForUpdateString(String aliases)

  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.

### supportsSequences

    public boolean supportsSequences()

  Description copied from class: `Dialect`
  Does this dialect support sequences?

  Overrides:
    `supportsSequences` in class `Dialect`
  Returns:
    True if sequences supported; false otherwise.

### 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 s limit clause to the query.

  Typically dialects utilize `variable` limit caluses when they support limits. Thus, when building the select command we do not actually need to know the limit or the offest 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

### bindLimitParametersFirst

    public boolean bindLimitParametersFirst()

  Description copied from class: `Dialect`
  Does the `LIMIT` clause come at the start of the `SELECT` statement, rather than at the end?

  Overrides:
    `bindLimitParametersFirst` in class `Dialect`
  Returns:
    true if limit parameters should come before other parameters

### 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

### getCurrentTimestampCallString

    public String getCurrentTimestampCallString()

### isCurrentTimestampSelectStringCallable

    public boolean isCurrentTimestampSelectStringCallable()

  Description copied from class: `Dialect`
  Should the value returned by `Dialect.getCurrentTimestampSelectString()` be treated as callable. Typically this indicates that JDBC escape sytnax is being used...

  Overrides:
    `isCurrentTimestampSelectStringCallable` in class `Dialect`
  Returns:
    True if the `Dialect.getCurrentTimestampSelectString()` return is callable; false otherwise.
