Constructor	Description
Oracle()	Creates the Oracle backend.

Method Summary

Modifier and Type	Method	Description
void	buildSelectSql(StringBuilder sqlBuilder, boolean writeLock, int limit, int offset)	Creates a select statement string from an inner sql string.
protected String	extractWhereClause(String sql, int whereOffset)	Extracts the where clause from a given sql.
String	getName()	Gets the name of the backend.
boolean	isDeprecated()	Returns whether this backend is deprecated and superseded by a newer implementation. Deprecated backends are omitted from BackendFactory.getAllBackends().
void	validateVersion(int databaseMajorVersion, int databaseMinorVersion)	Verifies that the major and minor version of the connection's metadata is compatible with this backend. If the latest backend is not compatible, the URL may be post-fixed with a backend type for an older version, for example:

Constructor Details

Oracle

public Oracle()

Creates the Oracle backend.

Method Details

isDeprecated

public boolean isDeprecated()

Description copied from interface: Backend

Returns whether this backend is deprecated and superseded by a newer implementation.
Deprecated backends are omitted from BackendFactory.getAllBackends().

Specified by:

isDeprecated in interface Backend

Overrides:

isDeprecated in class Oracle8

Returns:

true if deprecated

getName

public String getName()

Description copied from interface: Backend

Gets the name of the backend.

Specified by:

getName in interface Backend

Overrides:

getName in class Oracle8

Returns:

the name

validateVersion

public void validateVersion(int databaseMajorVersion,
 int databaseMinorVersion)

Description copied from interface: Backend

Verifies that the major and minor version of the connection's metadata is compatible with this backend.
If the latest backend is not compatible, the URL may be post-fixed with a backend type for an older version, for example:

   jdbc:oracle:thin:@//localhost:1521/xe|Oracle8
 

Throws BackendException if incompatible.

Specified by:

validateVersion in interface Backend

Overrides:

validateVersion in class AbstractBackend

Parameters:

databaseMajorVersion - the major version

databaseMinorVersion - the minor version

• BackendInfo(String, String, char[], String[])

buildSelectSql

public void buildSelectSql(StringBuilder sqlBuilder,
 boolean writeLock,
 int limit,
 int offset)

Description copied from interface: Backend

Creates a select statement string from an inner sql string.

sqlBuilder is anything as [SELECT] FROM... WHERE... ORDER BY....
It is decorated with a leading SELECT, if missing, plus optional clauses like for the given parameters.

Specified by:

buildSelectSql in interface Backend

Overrides:

buildSelectSql in class Oracle8

Parameters:

sqlBuilder - the sql builder, initially containing the inner sql without leading SELECT.

writeLock - true select should write lock

limit - the limit value, ≤ 0 if no limit clause

offset - the offset value, ≤ 0 if no offset clause

extractWhereClause

protected String extractWhereClause(String sql,
 int whereOffset)

Description copied from class: AbstractBackend

Extracts the where clause from a given sql.

Overrides:

extractWhereClause in class Oracle8

Parameters:

sql - the sql statement

whereOffset - the location of WHERE in sql

Returns:

the where clause without the keyword WHERE
