Constructor Details

ChDictionary

public ChDictionary(String name)

Creates a new ClickHouse dictionary with the specified name.

Parameters:

name - the name of the dictionary

Method Details

getStatementType

public DbObjType getStatementType()

Description copied from interface: IStatement

Gets the type of this database object.

Specified by:

getStatementType in interface IStatement

Returns:

the database object type

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

setSourceType

public void setSourceType(String sourceType)

setLifeTime

public void setLifeTime(String lifeTime)

setLayOut

public void setLayOut(String layOut)

setPk

public void setPk(String pk)

setRange

public void setRange(String range)

addColumn

public void addColumn(ChColumn column)

Adds a column to this dictionary.

Parameters:

column - the column to add

addSource

public void addSource(String key,
 String value)

addOption

public void addOption(String option,
 String value)

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
