SQLite에 다음 표가 있습니다.제약 조건 실패 - SQLite 3 - Android
StringBuilder createSql = new StringBuilder();
createSql.append("create table LIBRARY (");
createSql.append("id integer primary key, ");
createSql.append("title text, ");
createSql.append("author text, ");
createSql.append("publisher text, ");
createSql.append("thumbnailUrl text, ");
createSql.append("formatType text, ");
createSql.append("contentUrl text, ");
createSql.append("publicationType text, ");
createSql.append("favorite text, ");
createSql.append("started text, ");
createSql.append("normalizedTitle text, ");
createSql.append("downloaded integer, ");
createSql.append("wasDownloaded text ");
createSql.append(");");
다음 코드는이 테이블에 값을 삽입합니다.
public void addLibrary(LibraryItem item) {
ContentValues row = new ContentValues();
row.put("title", item.getTitle());
row.put("author", item.getAuthor());
row.put("publisher", item.getPublisher());
row.put("thumbnailUrl", item.getThumbnail());
row.put("formatType", item.getFormat());
row.put("contentUrl", item.getContentUrl());
row.put("publicationType", item.getPublicationType());
row.put("favorite", item.isFavorite() ? "YES" : "NO");
row.put("id", item.getItemId());
row.put("normalizedTitle", StringUtil.normalize(item.getTitle()));
row.put("downloaded", Calendar.getInstance().getTimeInMillis());
row.put("wasdownloaded", item.hasContent() ? "YES" : "NO");
long id = db.insert("LIBRARY", null, row);
add(id, item.getCategories());
}
그러나 실행할 때 다음 오류가 발생합니다.
Error inserting id=255 formatType=null author=null title=A Cabana contentUrl=/sdcard/Digital Editions/A Cabana.pdf publicationType=Livro thumbnailUrl=https://api-dls.homolog.abrildigital.com.br/images/22/android_cover_201103092041.jpg wasdownloaded=NO downloaded=1302631109426 normalizedTitle=A Cabana favorite=NO publisher=null
