응용 프로그램에서 PosgreSQL 쿼리 (EF + Devart)가 실패하지만 PgAdmin에서 작동합니다.

Question

Devart 커넥터가있는 Entity Framework에서 생성 한 SQL (PostgreSQL) 쿼리 중 하나에 문제가 있습니다. 정확히 60초 (마다) 후, 나는 오류 얻을 : 내가 연결 문자열에서 타임 아웃을 실험하려

을하지만, 도움이되지 않았다. 이것은 (EF에 의해 생성) DbContext.DataBase.Connection.ConnectionString

User Id=myuser;Host=myhost;Port=5432;Database=mydatabase;Unicode=True;Connection Timeout=300;Default Command Timeout=300;SSLMode=Disable; 

이 쿼리는 매우 큰의 내용이다. 그것은 6500 줄 이상의 코드 (결과가없는 query)를 가지고 있으며 수많은 UNION 문장으로 구성됩니다.

약 120 초에 실행 된 PgAdmin에서 동일한 쿼리가 수동으로 실행되었습니다.

아이디어가 있으십니까?

Answer 1

Default Command Timeout=300;

당신은 send us 기본 명령 제한 시간 연결 문자열 매개 변수를 무시하고 함께 문제를 재생 해당 DDL/DML 스크립트가있는 작은 테스트 프로젝트시겠습니까?
