Member Function Documentation

dbQueryClause * dbQueryField::clone (   )  const [virtual]

Implements dbQueryClause.

dbQueryClause * dbQueryField::cloneReplacingTable (  const dbTable *  inTable, const dbTable *  repTable )  const [virtual]

conditionally clone if embedded query requires replacement. Reimplemented from dbQueryClause.

void dbQueryField::describe (  std::ostream &   )  const [virtual]

Implements dbQueryClause.

const dbField* dbQueryField::field (   )  const [inline]

void dbQueryField::getSearchTables (  const dbTable *  inSchTable, dbTable *&  outDiffFieldTable, dbTable *&  outRelatedTable )  const [virtual]

Find tables on which we are searching, if not simply the field's table. Copes with two situations: 1) a search is being performed given a clause written on a different table, and we just need to map tables across 2) searches on related tables Reimplemented from dbQueryClause.

bool dbQueryClause::isSimpleIndexedSearch (   )  const [inherited]

Reimplemented in dbQueryBinary.
