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 class: PgStatement

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 class PgStatement

Parameters:

script - the SQL script to append creation statements to

fillSequenceBody

public void fillSequenceBody(StringBuilder sbSQL)

Description copied from class: AbstractSequence

Fills the sequence body SQL definition.

Specified by:

fillSequenceBody in class AbstractSequence

Parameters:

sbSQL - the StringBuilder to append the sequence body to

appendAlterSQL

public ObjectState appendAlterSQL(PgStatement newCondition,
 SQLScript script)

Description copied from class: PgStatement

Fill script with object changes and return change type

Specified by:

appendAlterSQL in class PgStatement

Parameters:

newCondition - new object state

script - script to collect changes

Returns:

object change type

setDataType

public void setDataType(String dataType)

Overrides:

setDataType in class AbstractSequence

setMinMaxInc

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

Description copied from class: AbstractSequence

Sets the minimum, maximum, and increment values for this sequence.

Specified by:

setMinMaxInc in class AbstractSequence

Parameters:

inc - the increment value

max - the maximum value

min - the minimum value

dataType - the data type of the sequence

precision - the precision for numeric types

setCached

public void setCached(boolean isCached)

compare

public boolean compare(PgStatement obj)

Description copied from class: PgStatement

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

Overrides:

compare in class AbstractSequence

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

Overrides:

computeHash in class AbstractSequence

Parameters:

hasher - the hasher instance to use for hash computation

getDbType

public DatabaseType getDbType()

Overrides:

getDbType in class PgStatement
