Member Function Documentation

◆ Close()

void KVSQLiteResult::Close ( Option_t * opt = "" )

finalvirtual

Close query result.

Implements TSQLResult.

Definition at line 57 of file KVSQLiteResult.cxx.

◆ GetFieldCount()

Int_t KVSQLiteResult::GetFieldCount ( )

finalvirtual

Get number of fields in result.

Implements TSQLResult.

◆ IsValid()

Bool_t KVSQLiteResult::IsValid ( Int_t field )

private

Check if result set is open and field index within range.

Definition at line 73 of file KVSQLiteResult.cxx.

◆ Next()

TSQLRow * KVSQLiteResult::Next ( void )

finalvirtual

Get next query result row. The returned object must be deleted by the user.

Implements TSQLResult.
