Constructor Summary

Constructors

Constructor	Description
MariaDb()	Creates the MariaDb backend.

Method Summary

Modifier and Type	Method	Description
String	getDriverClassName()	Gets the JDBC driver class name.
String	getName()	Gets the name of the backend.
protected boolean	isDropIfExistsSupported()	Adds "IF EXISTS" to drop clauses, if supported by the backend. Makes migration a little more robust in case the same SQL scripts are applied to different databases than those used to generate the migration scripts for.
boolean	isMatchingUrl(String url)	Checks whether the backend belongs to the given jdbc url. If multiple backend implementations are provided for the same database type, only one backend should match the URL.
boolean	isSequenceSupported()	True if backend provides locking-free sequences. Sequences must not take part in transactions, i.e.
String	sqlCreateSequence(String name, Long start, Long increment)	Creates the SQL string to create a sequence.
String	sqlNextFromSequence(String name)	Creates the SQL string to retrieve the next id from a sequence.

Constructor Details

MariaDb

public MariaDb()

Creates the MariaDb backend.

Method Details

isMatchingUrl

public boolean isMatchingUrl(String url)

Description copied from interface: Backend

Checks whether the backend belongs to the given jdbc url.
If multiple backend implementations are provided for the same database type, only one backend should match the URL. The others must be selected via name.

Specified by:

isMatchingUrl in interface Backend

Overrides:

isMatchingUrl in class MySql

Parameters:

url - the jdbc url

Returns:

true if matches

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 MySql

Returns:

the name

getDriverClassName

public String getDriverClassName()

Description copied from interface: Backend

Gets the JDBC driver class name.

Specified by:

getDriverClassName in interface Backend

Overrides:

getDriverClassName in class MySql

Returns:

the class name

isDropIfExistsSupported

protected boolean isDropIfExistsSupported()

Description copied from class: AbstractBackend

Adds "IF EXISTS" to drop clauses, if supported by the backend.
Makes migration a little more robust in case the same SQL scripts are applied to different databases than those used to generate the migration scripts for.

Overrides:

isDropIfExistsSupported in class AbstractBackend

Returns:

true if supported

isSequenceSupported

public boolean isSequenceSupported()

Description copied from interface: Backend

True if backend provides locking-free sequences.
Sequences must not take part in transactions, i.e. no read- or write-locks!

Specified by:

isSequenceSupported in interface Backend

Overrides:

isSequenceSupported in class AbstractSql92Backend

Returns:

true if database supports sequences

sqlNextFromSequence

public String sqlNextFromSequence(String name)

Description copied from interface: Backend

Creates the SQL string to retrieve the next id from a sequence.

Specified by:

sqlNextFromSequence in interface Backend

Overrides:

sqlNextFromSequence in class AbstractSql92Backend

Parameters:

name - the name of the sequence

Returns:

the SQL code

sqlCreateSequence

public String sqlCreateSequence(String name,
 Long start,
 Long increment)

Description copied from interface: Backend

Creates the SQL string to create a sequence.

Specified by:

sqlCreateSequence in interface Backend

Overrides:

sqlCreateSequence in class AbstractSql92Backend

Parameters:

name - the sequence name

start - the optional start value, defaults to 1

increment - the optional increment, defaults to 1

Returns:

the SQL code
