示例1: getUserColumnList
// -----------------------------------------------------------------------
// TableDesc::getUserColumnList()
// -----------------------------------------------------------------------
void TableDesc::getUserColumnList(ValueIdList &columnList) const
{
for (CollIndex i = 0; i < colList_.entries(); i++) {
ValueId valId = colList_[i];
NAColumn *column = valId.getNAColumn();
if (column->isUserColumn())
columnList.insert(valId);
}
}
示例2: setPrimaryKeyColumns
// this method sets the primary key columns. It goes through all the columns
// of the table, and collects the columns which are marked as primary keys
void TableDesc::setPrimaryKeyColumns()
{
ValueIdSet primaryColumns;
for ( CollIndex j = 0 ; j < colList_.entries() ; j++ )
{
ValueId valId = colList_[j];
NAColumn *column = valId.getNAColumn();
if ( column->isPrimaryKey() )
{
primaryColumns.insert(valId) ;
// mark column as referenced for histogram, as we may need its histogram
// during plan generation
if ((column->isUserColumn() || column->isSaltColumn() ) &&
(column->getNATable()->getSpecialType() == ExtendedQualName::NORMAL_TABLE) )
column->setReferencedForMultiIntHist();
}
}
