  - 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
```

  - 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, ... FROM ADDRESS WHERE (ADDRESS_ID = ?) FOR UPDATE on SQLServer platform (method returns false): SELECT ADDRESS_ID, ... FROM ADDRESS WITH (UPDLOCK) WHERE (ADDRESS_ID = ?)
    
    Overrides:
