I am a psql beginner and am using the libpq++ library to write a series of programs that access a database. My database is working well, my problem is with: PgCursor::Declare PgCursor CourseData(data, "Student_course_record_portal"); I create this cursor and am able to successfully do: CourseData.Declare(course_query.c_str()) CourseData.Fetch() CourseData.GetValue(i, course_fnum) It is when I want to repeat this process that I have problems. I want to Declare a different string for the same PgCursor. and then fetch from this new string's value (a select stmt) If I just do one or the other things work correctly, but the repeating of Declare and Fetch cause: NOTICE: (transaction aborted): queries ignored until END which then leads to the Fetch not working..... I have also tried to just create a different PgCursor - but this leads to an error about not being in the default state. Does anyone know of a fix - or am I making a stupid mistake?
