Constructor Details

MsIndex

public MsIndex(String name)

Creates a new Microsoft SQL index.

Parameters:

name - the index name

Method Details

setColumnstore

public void setColumnstore(boolean isColumnstore)

addOrderCol

public void addOrderCol(String orderCol)

Adds a column to the ORDER clause for columnstore indexes.

Parameters:

orderCol - the column specification for ordering

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

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

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 AbstractIndex

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 AbstractIndex

Parameters:

hasher - the hasher instance to use for hash computation

getDbType

public DatabaseType getDbType()

Overrides:

getDbType in class PgStatement
