Constructor Details

MsSequence

public MsSequence(String name)

Creates a new Microsoft SQL sequence with BIGINT data type as default.

Parameters:

name - the sequence name

Method Details

getCreationSQL

public void getCreationSQL(SQLScript script)

Description copied from interface: IStatement

Generates the SQL statements needed to create this database object. This is an abstract method that must be implemented by subclasses to provide the specific CREATE SQL for each object type.

Specified by:

getCreationSQL in interface IStatement

Parameters:

script - the SQL script to append creation statements to

appendAlterSQL

public ObjectState appendAlterSQL(IStatement newCondition,
 SQLScript script)

Description copied from interface: IStatement

Fill script with object changes and return change type

Specified by:

appendAlterSQL in interface IStatement

Parameters:

newCondition - new object state

script - script to collect changes

Returns:

object change type

setDataType

public void setDataType(String dataType)

setMinMaxInc

public void setMinMaxInc(long inc,
 Long max,
 Long min,
 String dataType,
 long precision)

setCached

public void setCached(boolean isCached)

setStartWith

public void setStartWith(String startWith)

setCycle

public void setCycle(boolean cycle)

setCache

public void setCache(String cache)

getRelationColumns

public Stream<Pair<String,String>> getRelationColumns()

Description copied from interface: IRelation

Gets the columns of this relation as name-type pairs.

Specified by:

getRelationColumns in interface IRelation

Returns:

a stream of column name and type pairs

computeHash

public void computeHash(Hasher hasher)

Description copied from interface: IHashable

Computes the hash of the implementing object using the provided hasher. The implementation should call appropriate put methods on the hasher for all fields that should contribute to the hash value.

Specified by:

computeHash in interface IHashable

Parameters:

hasher - the hasher instance to use for hash computation

compare

public boolean compare(IStatement obj)

Description copied from class: AbstractStatement

This method does not account for nested child PgStatements. Shallow version of AbstractStatement.equals(Object)

Specified by:

compare in interface IStatement

Overrides:

compare in class AbstractStatement
