createStore

public static IDBStore createStore(IMappingStrategy mappingStrategy,
                                   org.eclipse.net4j.db.IDBAdapter dbAdapter,
                                   org.eclipse.net4j.db.IDBConnectionProvider dbConnectionProvider)

createMappingStrategy

public static IMappingStrategy createMappingStrategy(java.lang.String type)

Can only be used when Eclipse is running. In standalone scenarios create the mapping strategy instance by directly calling the constructor of the mapping strategy class.

Since:

2.0

#createHorizontalMappingStrategy()

getLong

public static long getLong(CDOID id)

Get the long value of a CDOID (by delegating to CDOIDUtil.getLong(org.eclipse.emf.cdo.common.id.CDOID)) In addition, provide a check for external IDs which are not supported by the DBStore

Parameters:

id - the ID to convert to long

Returns:

the long value of the ID

Throws:

java.lang.IllegalArgumentException - if the ID is not convertibla

Since:

2.0

sqlUpdate

public static int sqlUpdate(java.sql.PreparedStatement stmt,
                            boolean exactlyOne)
                     throws java.sql.SQLException

Execute update on the given prepared statement and handle common cases of return values.

Parameters:

stmt - the prepared statement

exactlyOne - if true, the update count is checked to be 1. Else the update result is only checked so that the update was successful (i.e. result code != Statement.EXECUTE_FAILED).

Returns:

the update count / execution result as returned by PreparedStatement.executeUpdate(). Can be used by the caller to perform more advanced checks.

Throws:

java.sql.SQLException - if PreparedStatement.executeUpdate() throws it.

java.lang.IllegalStateException - if the check indicated by excatlyOne indicates an error.
