public String	getCreateSequenceString(String The name of the sequence sequenceName) Overrides default org.hibernate.dialect.sequence.SequenceSupport.getCreateSequenceString. Typically dialects which support sequences can create a sequence with a single command.
public String	getCreateSequenceString(String The name of the sequence sequenceName, int The initial value to apply to 'create sequence' statement initialValue, int The increment value to apply to 'create sequence' statement incrementSize) Overrides default org.hibernate.dialect.sequence.SequenceSupport.getCreateSequenceString.

public String	getSelectSequenceNextValString(String the name of the sequence sequenceName) Implements org.hibernate.dialect.sequence.SequenceSupport.getSelectSequenceNextValString. Generate the select expression fragment that will retrieve the next value of a sequence as part of another (typically DML) statement.
public String	getSelectSequencePreviousValString(String the name of the sequence sequenceName) Overrides default org.hibernate.dialect.sequence.SequenceSupport.getSelectSequencePreviousValString.

public String getCreateSequenceString(String sequenceName) Overrides default org.hibernate.dialect.sequence.SequenceSupport.getCreateSequenceString. Doc from org.hibernate.dialect.sequence.SequenceSupport.getCreateSequenceString. Typically dialects which support sequences can create a sequence with a single command. This method is a convenience making it easier to implement `getCreateSequenceStrings(String, int, int)` for these dialects. The default definition is to return `create sequence sequenceName` for the argument `sequenceName`. Dialects need to override this method if a sequence created in this manner does not start at 1, or if the syntax is nonstandard. 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 override `getCreateSequenceStrings(String, int, int)` instead. Parameters sequenceName:String The name of the sequence Returns:String The sequence creation command Annotations @Override

public String getCreateSequenceString(String sequenceName)

Typically dialects which support sequences can create a sequence with a single command. This method is a convenience making it easier to implement getCreateSequenceStrings(String, int, int) for these dialects.

The default definition is to return create sequence sequenceName for the argument sequenceName. Dialects need to override this method if a sequence created in this manner does not start at 1, or if the syntax is nonstandard.

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 override getCreateSequenceStrings(String, int, int) instead.

Parameters

sequenceName:String: The name of the sequence

Returns:String

The sequence creation command

public String getCreateSequenceString(String sequenceName, int initialValue, int incrementSize) Overrides default org.hibernate.dialect.sequence.SequenceSupport.getCreateSequenceString. Doc from org.hibernate.dialect.sequence.SequenceSupport.getCreateSequenceString. Typically dialects which support sequences can create a sequence with a single command. This method is a convenience making it easier to implement `getCreateSequenceStrings(String, int, int)` for these dialects. Overloaded form of `getCreateSequenceString(String)`, additionally taking the initial value and increment size to be applied to the sequence definition. The default definition is to suffix `getCreateSequenceString(String)` with the string: `start with initialValue increment by incrementSize` for the arguments `initialValue` and `incrementSize`. Dialects need to override this method if different key phrases are used to apply the allocation information. Parameters sequenceName:String The name of the sequence initialValue:int The initial value to apply to 'create sequence' statement incrementSize:int The increment value to apply to 'create sequence' statement Returns:String The sequence creation command Annotations @Override

public String getSelectSequenceNextValString(String sequenceName) Implements org.hibernate.dialect.sequence.SequenceSupport.getSelectSequenceNextValString. Doc from org.hibernate.dialect.sequence.SequenceSupport.getSelectSequenceNextValString. Generate the select expression fragment that will retrieve the next value of a sequence as part of another (typically DML) statement. This differs from `getSequenceNextValString(String)` in that it must return an expression usable within another statement. Parameters sequenceName:String the name of the sequence Returns:String The "next value" fragment. Annotations @Override
