Android - SQLite - no such column error (greenDAO)

问题

I created my table structure with greenDAO and when updating the following table, I'm getting the follwing error:

android.database.sqlite.SQLiteException: no such column: BODY_LOG_ENTRY._id: ,
 while compiling: UPDATE BODY_LOG_ENTRY SET 
'BODY_LOG_ENTRY._id'=?,

'BODY_LOG_ENTRY.THIGHES_RIGHT'=?,
'BODY_LOG_ENTRY.CALVES_LEFT'=?,
'BODY_LOG_ENTRY.CALVES_RIGHT'=? 
WHERE BODY_LOG_ENTRY.'_id'=?

I already checked if all columns exist, and they do!
I checked the names of the columns and they match
I checked if a column name matches one keyword, but I did not find one (http://www.sqlite.org/lang_keywords.html)

does anybody have any idea what the problem could be?

Following is the current create table query:

public static void createTable(SQLiteDatabase db, boolean ifNotExists) {
    String constraint = ifNotExists? "IF NOT EXISTS ": "";
    db.execSQL("CREATE TABLE " + constraint + "'BODY_LOG_ENTRY' (" + //
            " '_id' INTEGER PRIMARY KEY ," + // 0: id

            " 'BODY_FAT_FORMULA_DATA2' REAL NOT NULL ," + // 8: bodyFatFormulaData2
            " 'BODY_FAT_FORMULA_DATA3' REAL NOT NULL ," + // 9: bodyFatFormulaData3

            " 'FOREARM_LEFT' REAL NOT NULL ," + // 24: forearmLeft
            " 'FOREARM_RIGHT' REAL NOT NULL ," + // 25: forearmRight
            " 'BUTT' REAL NOT NULL ," + // 26: butt
            " 'THIGHES_LEFT' REAL NOT NULL ," + // 27: thighesLeft
            " 'THIGHES_RIGHT' REAL NOT NULL ," + // 28: thighesRight
            " 'CALVES_LEFT' REAL NOT NULL ," + // 29: calvesLeft
            " 'CALVES_RIGHT' REAL NOT NULL );"); // 30: calvesRight
    // Add Indexes
    db.execSQL("CREATE INDEX " + constraint + "IDX_BODY_LOG_ENTRY_FK_DAY ON BODY_LOG_ENTRY" +
            " (FK_DAY);");
    db.execSQL("CREATE INDEX " + constraint + "IDX_BODY_LOG_ENTRY_DAY_ORDER ON BODY_LOG_ENTRY" +
            " (DAY_ORDER);");
}

PS: all I can say is, that the table prefix should not be part of the update query, because without them, the query works... but the weird thing is, that all my other (>20) tables work... just this one does not

回答1:

When you update any fields, this updates don't refresh in the actual DB. A solution that worked for me, is delete all tables in the DB and then create all tables again. In my case, my database was empty.

See the next link: How to clean/delete greenDao database

Other option is do ALTER TABLE on existing database.

回答2:

I just encountered the same problem,you can try this : check the table which is a new table or a old table ,because we always create table with "if not exists". PS: 1.I am from China,my English is poor , Pray you can understand my words. 2.the answer is for someone who will meet the same question after me.
