    SYSFUN functions. Table of functions that automatically appear in the SYSFUN schema. These functions are resolved to directly if no schema name is given, e.g. SELECT COS(angle) FROM ROOM_WALLS Adding a function here is suitable when the function defintion can have a single return type and fixed parameter types. Functions that need to have a return type based upon the input type(s) are not supported here. Typically those are added into the parser and methods added into the DataValueDescriptor interface. Examples are character based functions whose return type length is based upon the passed in type, e.g. passed a CHAR(10) returns a CHAR(10). This simple table can handle an arbitrary number of arguments and RETURNS NULL ON NULL INPUT. The scheme could be expanded to handle other function options such as other parameters if needed. [0] = FUNCTION name [1] = RETURNS type [2] = Java class [3] = method name and signature [4] = "true" or "false" depending on whether the function is DETERMINSTIC [5] = "true" or "false" depending on whether the function has VARARGS [6..N] = arguments (optional, if not present zero arguments is assumed)

    Scan indexNo index on a permission table catalog, looking for match(es) for the grantee column (given by granteeColnoInIndex for the catalog in question). The action argument can be either EXISTS or DROP (to check for existence, or to drop that row). There is no index on grantee column only on on any of the permissions tables, so we use the index which contain grantee and scan that, setting up a scan qualifier to match the grantee, then fetch the base row. If this proves too slow, we should add an index on grantee only.
    
    Parameters:
    
    authId - grantee to match against
    
    tc - transaction controller
    
    catalog - the underlying permission table to visit
    
    indexNo - the number of the index by which to access the catalog
    
    granteeColnoInIndex - the column number to match authId against
    
    action - drop matching rows (DROP), or return true if there is a matching row (EXISTS)
    
    Returns:

    Description copied from interface: DataDictionary
    
    This method does the job of transforming the trigger action plan text as shown below. DELETE FROM t WHERE c = old.c turns into DELETE FROM t WHERE c = org.apache.derby.iapi.db.Factory:: getTriggerExecutionContext().getOldRow(). getInt(columnNumberFor'C'inRuntimeResultset); In addition to that, for CREATE TRIGGER time, it does the job of collecting the column positions of columns referenced in trigger action plan through REFERENCEs clause. This information will get saved in SYSTRIGGERS table by the caller in CREATE TRIGGER case. It gets called either 1)at the trigger creation time for row level triggers or 2)if the trigger got invalidated by some other sql earlier and the current sql needs that trigger to fire. For such a trigger firing case, this method will get called only if it is row level trigger with REFERENCES clause. This work was done as part of DERBY-4874. Before DERBY-4874, once the stored prepared statement for trigger action plan was generated, it was never updated ever again. But, one case where the trigger action plan needs to be regenerated is say when the column length is changed for a column which is REFERENCEd as old or new column value. eg of such a case would be say the Alter table has changed the length of a varchar column from varchar(30) to varchar(64) but the stored prepared statement associated with the trigger action plan continued to use varchar(30). To fix varchar(30) in stored prepared statement for trigger action sql to varchar(64), we need to regenerate the trigger action sql. This new trigger action sql will then get updated into SYSSTATEMENTS table. If we are here for case 1) above, then we will collect all column references in trigger action through new/old transition variables. Information about them will be saved in SYSTRIGGERS table DERBY-1482 (if we are dealing with pre-10.7 db, then we will not put any information about trigger action columns in the system table to ensure backward compatibility). This information along with the trigger columns will decide what columns from the trigger table will be fetched into memory during trigger execution. If we are here for case 2) above, then all the information about column references in trigger action has already been collected during CREATE TRIGGER time and hence we can use that available information about column positions to do the transformation of OLD/NEW transient references. More information on case 1) above. DERBY-1482 One of the work done by this method for row level triggers is to find the columns which are referenced in the trigger action through the REFERENCES clause ie thro old/new transition variables. This information will be saved in SYSTRIGGERS so it can be retrieved during the trigger execution time. The purpose of this is to recognize what columns from the trigger table should be read in during trigger execution. Before these code changes, during trigger execution, Derby was opting to read all the columns from the trigger table even if they were not all referenced during the trigger execution. This caused Derby to run into OOM at times when it could really be avoided. We go through the trigger action text and collect the column positions of all the REFERENCEd columns through new/old transition variables. We keep that information in SYSTRIGGERS. At runtime, when the trigger is fired, we will look at this information along with trigger columns from the trigger definition and only fetch those columns into memory rather than all the columns from the trigger table. This is especially useful when the table has LOB columns and those columns are not referenced in the trigger action and are not recognized as trigger columns. For such cases, we can avoid reading large values of LOB columns into memory and thus avoiding possibly running into OOM errors. If there are no trigger columns defined on the trigger, we will read all the columns from the trigger table when the trigger fires because no specific columns were identified as trigger column by the user. The other case where we will opt to read all the columns are when trigger columns and REFERENCING clause is identified for the trigger but there is no trigger action column information in SYSTRIGGERS. This can happen for triggers created prior to 10.7 release and later that database got hard/soft-upgraded to 10.7 or higher release.

    Return a (single or list of) catalog row descriptor(s) from a system table where the access is from the index to the heap. This overload variant takes an explicit tc, in contrast to the normal one which uses the one returned by getTransactionCompile.
    
    Parameters:
    
    indexId - The id of the index (0 to # of indexes on table) to use
    
    keyRow - The supplied ExecIndexRow for search
    
    ti - The TabInfoImpl to use
    
    parentTupleDescriptor - The parentDescriptor, if applicable.
    
    list - The list to build, if supplied. If null, then caller expects a single descriptor
    
    returnType - The type of descriptor to return
    
    forUpdate - Whether or not to open the index for update.
    
    isolationLevel - Use this explicit isolation level. Only ISOLATION_REPEATABLE_READ (normal usage) or ISOLATION_READ_UNCOMMITTED (corner cases) supported for now.
    
    tc - Transaction controller
    
    Returns:
    
    The last matching descriptor. If isolationLevel is ISOLATION_READ_UNCOMMITTED, the base row may be gone by the time we access it via the index; in such a case a null is returned.
    
    Throws:

  - getSystemSQLName
```
public java.lang.String getSystemSQLName()
```
    Returns a unique system generated name of the form SQLyymmddhhmmssxxn yy - year, mm - month, dd - day of month, hh - hour, mm - minute, ss - second, xx - the first 2 digits of millisec because we don't have enough space to keep the exact millisec value, n - number between 0-9 The number at the end is to handle more than one system generated name request came at the same time. In that case, the timestamp will remain the same, we will just increment n at the end of the name. Following is how we get around the problem of more than 10 system generated name requestes at the same time: When the database boots up, we start a counter with value -1 for the last digit in the generated name. We also keep the time in millisec to keep track of when the last system name was generated. At the boot time, it will be default to 0L. In addition, we have a calendar object for the time in millisec That calendar object is used to fetch yy, mm, dd, etc for the string SQLyymmddhhmmssxxn When the first request for the system generated name comes, time of last system generated name will be less than the current time. We initialize the counter to 0, set the time of last system generated name to the current time truncated off to lower 10ms time. The first name request is the only time we know for sure the time of last system generated name will be less than the current time. After this first request, the next request could be at any time. We go through the following algorithm for every generated name request. First check if the current time(truncated off to lower 10ms) is greater than the timestamp for last system generated name If yes, then we change the timestamp for system generated name to the current timestamp and reset the counter to 0 and generate the name using the current timestamp and 0 as the number at the end of the generated name. If no, then it means this request for generated name has come at the same time as last one. Or it may come at a time less than the last generated name request. This could be because of seasonal time change or somebody manually changing the time on the computer. In any case, if the counter is less than 10(meaning this is not yet our 11th request for generated name at a given time), we use that in the generated name. But if the counter has reached 10(which means, this is the 11th name request at the same time), then we increment the system generated name timestamp by 10ms and reset the counter to 0 (notice, at this point, the timestamp for system generated names is not in sync with the real current time, but we need to have this mechanism to get around the problem of more than 10 generated name requests at a same physical time).

```
    Description copied from interface: DataDictionary
    
    Return the Java class to use for the VTI to which the received table descriptor maps. There are two kinds of VTI mappings that we do: the first is for "table names", the second is for "table function names". Table names can only be mapped to VTIs that do not accept any arguments; any VTI that has at least one constructor which accepts one or more arguments must be mapped from a table *function* name. An example of a VTI "table name" is the following: select * from SYSCS_DIAG.LOCK_TABLE In this case "SYSCS_DIAG.LOCK_TABLE" is the table name that we want to map. Since the corresonding VTI does not accept any arguments, this VTI table name can be used anywhere a normal base table name can be used. An example of a VTI "table function name" is the following: select * from TABLE(SYSCS_DIAG.SPACE_TABLE(?)) x In this case "SYSCS_DIAG.SPACE_TABLE" is the table function name that we want to map. Since the corresponding VTI can take either one or two arguments we have to use the TABLE constructor syntax to pass the argument(s) in as if we were making a function call. Hence the term "table function".
    
    Specified by:
    
    getVTIClass in interface DataDictionary
    
    Parameters:
    
    td - Table descriptor used for the VTI look-up.
    
    asTableFunction - If false then treat td's descriptor name as a VTI "table name"; if true, treat the descriptor name as a VTI "table function name".
    
    Returns:
    
    Java class name to which "td" maps, or null if no mapping is found.

  - dropAllPermDescriptors
```
public void dropAllPermDescriptors(UUID objectID,
                                   TransactionController tc)
                            throws StandardException
```
    Drops all permission descriptors for the object whose Id is given.
    
    Specified by:
    
    dropAllPermDescriptors in interface DataDictionary
    
    Parameters:
    
    objectID - The UUID of the object from which to drop all the permission descriptors
    
    tc - TransactionController for the transaction
    
    Throws:
    
    StandardException - Thrown on error
  - getIndexStatsRefresher
```
public IndexStatisticsDaemon getIndexStatsRefresher(boolean asDaemon)
```
    Returns the index statistics refresher.
    
    Specified by:
    
    getIndexStatsRefresher in interface DataDictionary
    
    Parameters:
    
    asDaemon - whether the usage is automatic (true) or explicit (false)
    
    Returns:
    
    The index statistics refresher instance, or null if disabled. If asDaemon is false, an instance will always be returned.
  - disableIndexStatsRefresher
```
public void disableIndexStatsRefresher()
```
    Disables automatic refresh/creation of index statistics at runtime.
    If the daemon is disabled, it can only be enabled again by rebooting the database. Note that this method concerns diabling the daemon at runtime, and only the automatic updates of statistics. If wanted, the user would disable the daemon at boot-time by setting a property (system-wide or database property).
    Usage note: This method was added to allow the index refresher itself to notify the data dictionary that it should be disabled. This only happens if the refresher/daemon experiences severe errors, or a large amount of errors. It would then disable itself to avoid eating up system resources and potentially cause side-effects due to the errors.
    
    Specified by:
    
    disableIndexStatsRefresher in interface DataDictionary
  - doCreateIndexStatsRefresher
```
public boolean doCreateIndexStatsRefresher()
```
    Tells if an index statistics refresher should be created for this database.
    The only reason not to create an index statistics refresher is if one already exists.
    
    Specified by:
    
    doCreateIndexStatsRefresher in interface DataDictionary
    
    Returns:
    
    true if an index statistics refresher should be created, false if one already exists.
  - createIndexStatsRefresher
```
public void createIndexStatsRefresher(Database db,
                                      java.lang.String dbName)
```
    Creates an index statistics refresher for this data dictionary.
    The index statistics refresher is used to create and refresh index cardinality statistics, either automatically or on user demand (i.e. by invoking SYSCS_UTIL.SYSCS_UPDATE_STATISTICS).
    
    Specified by:
    
    createIndexStatsRefresher in interface DataDictionary
    
    Parameters:
    
    db - the database object associated with this data dictionary
    
    dbName - the name of the database
