public java.util.Vector getNativeTableInfo(java.lang.String table,

                                           org.eclipse.persistence.internal.sessions.AbstractSession session)
Return the catalog information through using the native SQL catalog selects. This is required because many JDBC driver do not support meta-data. Willcards can be passed as arguments.


getOutputProcedureToken

public java.lang.String getOutputProcedureToken()
This method is used to print the output parameter token when stored procedures are called

Overrides:
getOutputProcedureToken in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

getProcedureArgumentString

public java.lang.String getProcedureArgumentString()
Used for sp defs.

Overrides:
getProcedureArgumentString in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

Specified by:
getTimestampQuery in interface org.eclipse.persistence.internal.databaseaccess.Platform
Overrides:
getTimestampQuery in class org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform

getSelectForUpdateString

public java.lang.String getSelectForUpdateString()
INTERNAL: Lock. UPDLOCK seems like the correct table hint to use: HOLDLOCK is too weak - doesn't lock out another read with HOLDLOCK, XLOCK is too strong - locks out another read which doesn't use any locks. UPDLOCK seems to behave exactly like Oracle's FOR UPDATE: locking out updates and other reads with FOR UPDATE but allowing other reads without locks. SQLServer seems to decide itself on the granularity of the lock - it could lock more than the returned rows (for instance a page). It could be forced to obtain to make sure to obtain row level lock: WITH (UPDLOCK, ROWLOCK) However this approach is strongly discouraged because it can consume too much resources: selecting 900 rows from and requiring a "personal" lock for each row may not be feasible because of not enough memory available at the moment - in that case SQLServer will wait until the resource becomes available.

Overrides:
getSelectForUpdateString in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

getSelectForUpdateNoWaitString

public java.lang.String getSelectForUpdateNoWaitString()
INTERNAL: This syntax does no wait on the lock.

Overrides:
getSelectForUpdateNoWaitString in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

executeStoredProcedure

public java.lang.Object executeStoredProcedure(org.eclipse.persistence.internal.databaseaccess.DatabaseCall dbCall,
                                               java.sql.PreparedStatement statement,
                                               org.eclipse.persistence.internal.databaseaccess.DatabaseAccessor accessor,
                                               org.eclipse.persistence.internal.sessions.AbstractSession session)
                                        throws java.sql.SQLException
because each platform has different requirements for accessing stored procedures and the way that we can combine resultsets and output params the stored procedure call is being executed on the platform. This entire process needs some serious refactoring to eliminate the chance of bugs.

Overrides:
executeStoredProcedure in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform
Throws:
java.sql.SQLException

shouldPrintLockingClauseAfterWhereClause

public boolean shouldPrintLockingClauseAfterWhereClause()
INTERNAL: Indicates whether locking clause should be printed after where clause by SQLSelectStatement. Example: on Oracle platform (method returns true): SELECT ADDRESS_ID, ...
