Method Summary

Modifier and Type	Method	Description
DbAttribute	buildAttribute(String name, String typeName, int type, int size, int scale, boolean allowNulls)	Creates and returns a DbAttribute based on supplied parameters (usually obtained from database meta data).
protected void	configureExtendedTypes(ExtendedTypeMap map)	Called from JdbcAdapter.initExtendedTypes(List, List, List, ValueObjectTypeRegistry) to load adapter-specific types into the ExtendedTypeMap right after the default types are loaded, but before the DI overrides are.
String	createFkConstraint(DbRelationship rel)	Returns a SQL string that can be used to create a foreign key constraint for the relationship.
protected PkGenerator	createPkGenerator()	Creates and returns a primary key generator.
String	createTable(DbEntity ent)	Returns a SQL string that can be used to create database table corresponding to ent parameter.
String	getBatchTerminator()	Returns word "go".
QualifierTranslator	getQualifierTranslator(QueryAssembler queryAssembler)	Returns OpenBase-specific translator for queries.
SelectTranslator	getSelectTranslator(SelectQuery<?> query, EntityResolver entityResolver)	Returns a SelectTranslator that works with the adapter target database.
String	tableTypeForView()	Returns null, since views are not yet supported in openbase.

Method Details

getSelectTranslator

public SelectTranslator getSelectTranslator(SelectQuery<?> query,
EntityResolver entityResolver)

Description copied from interface: DbAdapter

Returns a SelectTranslator that works with the adapter target database.

Specified by:

getSelectTranslator in interface DbAdapter

Overrides:

getSelectTranslator in class JdbcAdapter

Since:

4.0

configureExtendedTypes

protected void configureExtendedTypes(ExtendedTypeMap map)

Description copied from class: JdbcAdapter

Called from JdbcAdapter.initExtendedTypes(List, List, List, ValueObjectTypeRegistry) to load adapter-specific types into the ExtendedTypeMap right after the default types are loaded, but before the DI overrides are. This method has specific implementations in JdbcAdapter subclasses.

Overrides:

configureExtendedTypes in class JdbcAdapter

buildAttribute

public DbAttribute buildAttribute(String name,
String typeName,
int type,
int size,
int scale,
boolean allowNulls)

Description copied from interface: DbAdapter

Creates and returns a DbAttribute based on supplied parameters (usually obtained from database meta data).

Specified by:

buildAttribute in interface DbAdapter

Overrides:

buildAttribute in class JdbcAdapter

Parameters:

name - database column name

typeName - database specific type name, may be used as a hint to determine the right JDBC type.

type - JDBC column type

size - database column size (ignored if less than zero)

scale - database column scale, i.e. the number of decimal digits (ignored if less than zero)

allowNulls - database column nullable parameter

getBatchTerminator

public String getBatchTerminator()

Returns word "go".

Specified by:

getBatchTerminator in interface DbAdapter

Overrides:

getBatchTerminator in class JdbcAdapter

tableTypeForView

public String tableTypeForView()

Returns null, since views are not yet supported in openbase.

Specified by:

tableTypeForView in interface DbAdapter

Overrides:

tableTypeForView in class JdbcAdapter

getQualifierTranslator

public QualifierTranslator getQualifierTranslator(QueryAssembler queryAssembler)

Returns OpenBase-specific translator for queries.

Specified by:

getQualifierTranslator in interface DbAdapter

Overrides:

getQualifierTranslator in class JdbcAdapter

createPkGenerator

protected PkGenerator createPkGenerator()

Creates and returns a primary key generator. Overrides superclass implementation to return an instance of OpenBasePkGenerator that uses built-in multi-server primary key generation.

Overrides:

createPkGenerator in class JdbcAdapter

createTable

public String createTable(DbEntity ent)

Returns a SQL string that can be used to create database table corresponding to ent parameter.

Specified by:

createTable in interface DbAdapter

Overrides:

createTable in class JdbcAdapter

createFkConstraint

public String createFkConstraint(DbRelationship rel)

Returns a SQL string that can be used to create a foreign key constraint for the relationship.

Specified by:

createFkConstraint in interface DbAdapter

Overrides:

createFkConstraint in class JdbcAdapter
