Question

My app crashes in the update query with following error

10-26 12:35:59.219: E/AndroidRuntime(23078): Caused by: android.database.sqlite.SQLiteException: no such column: current_Playlist.xml: , while compiling: UPDATE FileRevisionHistory SET FileRevision=? WHERE FileName=current_Playlist.xml

The code for updation is

public void updateFileRevision(FileRevision  inFileRevision) {
    ContentValues values = new ContentValues();
    values.put(MySQLiteHelper.KEY_REVISION, inFileRevision.mRevision);
    long updatetId = database.update(MySQLiteHelper.TABLE_REVISION_HISTORY, values,MySQLiteHelper.KEY_NAME + "=" + inFileRevision.mFileName,null);
    Log.i("DbExampleLog", "The file's rev is: " + updatetId);

What is wrong in my query ?

Answer 1

As the filename you specify is a string, it should be inside single quotes. Try this

long updatetId = database.update(MySQLiteHelper.TABLE_REVISION_HISTORY, values,MySQLiteHelper.KEY_NAME + "='" +inFileRevision.mFileName+ "'",null);
