InformixDatabase

public InformixDatabase()

Method Details

getSystemViews

protected Set<String> getSystemViews()

Description copied from class: AbstractJdbcDatabase

Returns system (undroppable) views.

Overrides:

getSystemViews in class AbstractJdbcDatabase

getPriority

public int getPriority()

getDefaultDatabaseProductName

protected String getDefaultDatabaseProductName()

Specified by:

getDefaultDatabaseProductName in class AbstractJdbcDatabase

getDefaultPort

public Integer getDefaultPort()

setConnection

public void setConnection(DatabaseConnection connection)

Specified by:

setConnection in interface Database

Overrides:

setConnection in class AbstractJdbcDatabase

getDefaultDriver

public String getDefaultDriver(String url)

Description copied from interface: Database

If this database understands the given url, return the default driver class name. Otherwise return null.

getShortName

public String getShortName()

Description copied from interface: Database

Returns an all-lower-case short name of the product. Used for end-user selecting of database type such as the DBMS precondition.

isCorrectDatabaseImplementation

public boolean isCorrectDatabaseImplementation(DatabaseConnection conn)
                                        throws DatabaseException

Description copied from interface: Database

Is this AbstractDatabase subclass the correct one to use for the given connection.

Throws:

DatabaseException

supportsInitiallyDeferrableColumns

public boolean supportsInitiallyDeferrableColumns()

Description copied from interface: Database

Returns whether this database support initially deferrable columns.

supportsTablespaces

public boolean supportsTablespaces()

getViewDefinition

public String getViewDefinition(CatalogAndSchema schema,
 String viewName)
                         throws DatabaseException

Specified by:

getViewDefinition in interface Database

Overrides:

Throws:

DatabaseException

getAutoIncrementClause

public String getAutoIncrementClause(BigInteger startWith,
 BigInteger incrementBy,
 String generationType,
 Boolean defaultOnNull)

Description copied from interface: Database

Returns database-specific auto-increment DDL clause.

Specified by:

getAutoIncrementClause in interface Database

Overrides:

getAutoIncrementClause in class AbstractJdbcDatabase

getDateLiteral

public String getDateLiteral(String isoDate)

Description copied from class: AbstractJdbcDatabase

Return a date literal with the same value as a string formatted using ISO 8601.

Note: many databases accept date literals in ISO8601 format with the 'T' replaced with a space. Only databases which do not accept these strings should need to override this method.

Implementation restriction: Currently, only the following subsets of ISO8601 are supported: yyyy-MM-dd hh:mm:ss yyyy-MM-ddThh:mm:ss

Specified by:

getDateLiteral in interface Database

Overrides:

getDateLiteral in class AbstractJdbcDatabase

public boolean supportsRestrictForeignKeys()

Specified by:

supportsRestrictForeignKeys in interface Database

Overrides:

supportsRestrictForeignKeys in class AbstractJdbcDatabase

public String escapeObjectName(String catalogName,
 String schemaName,
 String objectName,
 Class<? extends DatabaseObject> objectType)

Specified by:

escapeObjectName in interface Database

Overrides:

escapeObjectName in class AbstractJdbcDatabase

getSystemSchema

public String getSystemSchema()

Specified by:

getSystemSchema in interface Database

Overrides:

getSystemSchema in class AbstractJdbcDatabase

quoteObject

public String quoteObject(String objectName,
 Class<? extends DatabaseObject> objectType)

Overrides:

quoteObject in class AbstractJdbcDatabase

getConnectionSchemaName

protected String getConnectionSchemaName()

Description copied from class: AbstractJdbcDatabase

Overwrite this method to get the default schema name for the connection. If you only need to change the statement that obtains the current schema then override

Overrides:

getConnectionSchemaName in class AbstractJdbcDatabase

See Also:

• AbstractJdbcDatabase.getConnectionSchemaNameCallStatement()

supportsCatalogInObjectName

public boolean supportsCatalogInObjectName(Class<? extends DatabaseObject> type)

Specified by:

supportsCatalogInObjectName in interface Database

Overrides:

supportsCatalogInObjectName in class AbstractJdbcDatabase

supportsCreateIfNotExists

public boolean supportsCreateIfNotExists(Class<? extends DatabaseObject> type)

Description copied from interface: Database

Does the database support the "if not exits" syntax?

Parameters:

type - the DatabaseObject type to be checked.

Returns:

true if the "if not exists" syntax is supported, false otherwise.
