i have small problem, i googled it many times but i couldn't get it...
i'm using a query (sqlite) to retrieve some data ..
in this query their is Date() used to increase certain date dynamic number of days (coming from column in the same table) ..
if i put this days static (1,2,3,.....) it works fine but if i put column name it doesn't.
this query fails and i want it to work:
String selectQuery = "SELECT DISTINCT * FROM " + TABLE_NAME + " WHERE "
+ DATE + " = date('" + targetDate + "',' " + REPETITIONS + " day') ";
this works fine :
String selectQuery = "SELECT DISTINCT * FROM " + TABLE_NAME + " WHERE "
+ DATE + " = date('" + targetDate + "','2 day') ";
where
targetDate: date entered by user to get events of that date
DATE: date of every event in the table
REPETETIONS: dynamic number (column in the same table)
the problem is using REPETITIONS in the date function...
create statement
String SQL_CREATE_EVENT_TABLE = "CREATE TABLE " + TABLE_NAME + " ( " +
ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
TITLE + " TEXT ," +
DATE + " TEXT , " +
IS_NOTIFY + " INTEGER , " +
NOTIFICATION_TIME + " TEXT ," +
REPEAT + " INTEGER ," +
REPEAT_DURATION + " INTEGER ," +
REPETITIONS + " INTEGER ," +
CERTAIN_DATE + " TEXT ," +
NOTE + " TEXT ," +
IS_SPOKEN + " INTEGER " +
" );";
and this is the selecting statement
String selectQuery = "SELECT DISTINCT * FROM " + TABLE_NAME + " WHERE " + DATE + " = '" + targetDate
+ "' OR (( " + REPEAT + " = '1' AND " + REPEAT_DURATION + " = '0' ) AND " + DATE + " <= '" + targetDate + "')"
+ " OR( " + REPEAT + " = '1' AND " + REPEAT_DURATION + " = '3' ) AND " + DATE + " <= '" + targetDate + "' AND " + CERTAIN_DATE + " >= '" + targetDate + "'"
+ " OR (" + REPEAT + " = '1' AND " + REPEAT_DURATION + "= '2' ) AND " + targetDate + " >= '" + DATE + "' AND "+ targetDate+ " <= date('" + DATE + "','" + REPETITIONS + " days')";
The variable REPETITIONS in this statement:
String selectQuery = "SELECT DISTINCT * FROM " + TABLE_NAME + " WHERE "
+ DATE + " = date('" + targetDate + "',' " + REPETITIONS + " day') ";
should be a number and not a column name.
The date function in SQLite has various syntaxes but you use this one:
SELECT date('2014-10-23','+7 day');
you must supply a number before day.
Edit try this:
String selectQuery = "SELECT DISTINCT * FROM " + TABLE_NAME + " WHERE "
+ DATE + " = date('" + targetDate + "', " + REPETITIONS + " || ' day') ";
In sqlite date() function, the NNN days is a string modifier and not an expression. Therefore you cannot use column names or even || string concatenation there.
You can format the modifier string in your code and place it in the SQL. This requires additional query to the database, which is likely not what you want.
If you can assume each day is 24 hours (which is not always true, consider e.g. DST events), you could try something like
... date(strftime('%s', '" + targetDate + "', " + REPETITIONS + "*24*60*60, 'unixepoch') ...
where strftime('%s', ...) converts to seconds and date(..., 'unixepoch') converts back to datestamp.
But seriously I'd consider redesigning the schema to better support your functional requirements.

In my SpringBoot project I have CrudRepository with next method:

}
All query works well, but it ignores "order by" with case expression and list comes in inordered way. I am sending values as "lr.iban", "c.name" to orderBy parameter, and if translate it to sql, it works. But in JPQL it does not work.
So, where am I wrong? How can I solve it?
Also, if change last part with CASE expression to the next:
order by CASE WHEN :isAscending = true THEN c.name END ASC
It also works, well in JPQL. List comes in ordered way.
Could you please help what wrong with this query when calling from Java. When I run the same query in PL/SQL developer it runs perfectly but not when i call from java,.

Please note the PreparedStatement is from com.splwg.base.api.sql.PreparedStatement
I think you are passing different date formats in your where clause. Please try matching the date format of crE_dttm with To_Date('2016-03-10','YYYY-MM-DD')
e.g. to_date(crE_dttm, 'YYYY-MM-DD') < To_Date('2016-03-10','YYYY-MM-DD')

I have a table - event_log which has a field in Timestamp format. Some of the example entries are - '2016-01-28 12:37:48' , '2016-01-28 15:26:51'
Now I want to write a query that will select some rows between startTime and endTime. When I fire this Query in an SQL client
SELECT Time,Data
FROM event_log
WHERE Data IN ('player disconnected','Player connected to server')
AND Player_Details_ID = '1'
AND Time > '2016-01-28 11:46:49' AND Time < '2016-02-09 14:38:39'
ORDER BY Time;
it gives me the desired output. But when I write a similar query in Java it fails to give me the result.
sqlQuery = "Select e.Time,e.Data"
+ " from event_log e "
+ "where e.Data IN ('player disconnected','Player connected to server') "
+ "and e.Player_Details_ID = '1' and "
+ "e.TIME > " + "' + startSqlDate + '" + " and e.TIME < " + "' + endSqlDate + '"
+ " order by e.Time";
Where am I going wrong?
Regardless of the values of any 'startSqlDate' and 'endSqlDate' variables you may have defined, the query submitted to the database will invariably be:
Select e.Time,e.Data from event_log e where e.Data IN ('player disconnected','Player connected to server') and e.Player_Details_ID = '1' and e.TIME > ' + startSqlDate + ' and e.TIME < ' + endSqlDate + ' order by e.Time
That is because your variables names are in the string. Change it to this:
"Select e.Time,e.Data" + " from event_log e " + "where e.Data IN ('player disconnected','Player connected to server') " + "and e.Player_Details_ID = '1' and " + "e.TIME > '" + startSqlDate + "' and e.TIME < '" + endSqlDate + "' order by e.Time"
Your 5th line should be:
+ "e.TIME > '" + startSqlDate + "' and e.TIME < '" + endSqlDate + "'"
(Provided your variables are Strings in the right format.)
Your version doesn't use your variables at all, but compiles to a static String.
"e.TIME > " + "' + startSqlDate + '" + " and e.TIME < " + "' + endSqlDate + '"
instead of this , try below
"e.TIME > '"+ startSqlDate + "' and e.TIME < '"+ endSqlDate + '"+ " order by e.Time";
In my opinion you need to write \' than '.
This should avoid some problems with strings.
Also as you can see you have variable names in string.
Something like that should work:
sqlQuery = "SELECT e.Time,e.Data"
+ " FROM event_log e "
+ "WHERE e.Data IN (\'player disconnected\',\'Player connected to server\') "
+ "AND e.Player_Details_ID = \'1\' AND "
+ "e.TIME > " + "\'" + startSqlDate + "\'" + " AND e.TIME < " + "\'" + endSqlDate + "\'"
+ " ORDER BY e.Time";
I have a sample sqlite database that currently has 7 entries which is queried via:
String selectQuery = "SELECT * FROM " + TABLE_TRANSACTIONS + " x " +
"JOIN (SELECT " + KEY_TYPE_ID + ", COUNT(*) count FROM " + TABLE_TRANSACTIONS + " GROUP BY " + KEY_TYPE_ID + " ORDER BY count DESC) y " +
"ON x.type_id = y.type_id " + //type_id vs. KEY_TYPE_ID as alias won't recognize KEY_TYPE_ID
"WHERE x.type_id = " + TagData.TYPE_EXPENSE;
The output is:
Type A = 2500
Type A = 2599
Type B = 45000
Type C = 299
Type C = 2699
Type C = 10000
Type C = 12000
which correctly groups my types by their respective values. However, the ideal output would be:
Type B = 45000
Type C = 24998
Type A = 5099
where each type is then ordered by the sum of each type. Is this possible? If so what else should I be doing in my query? I'm relatively new to SQL and haven't been able to figure this out yet. Thank you in advance for any insight.
EDIT
Based on your input #CL. I now have a more simplified query:
String selectQuery = "SELECT *, SUM(" + KEY_AMOUNT + ") AS amount_sum " +
"FROM " + TABLE_TRANSACTIONS + " " +
"GROUP BY " + KEY_LABEL_ID + " " +
"ORDER BY amount_sum DESC";
which works as expected when I use sqlfiddle at http://www.sqlfiddle.com/#!5/b3615/1 but not when I use the query in Android. In Android, only the most recent entry for each label type is returned. The SUM doesn't seem to actually do its job.
What am I missing here?
Moving the aggregation and ordering into a subquery does not make sense.
If you want to get the count of all expense transactions per type, just use a simple aggregation:
SELECT Type_ID,
COUNT(*) count
FROM TRANSACTIONS
WHERE TYPE_IF = 'TYPE_EXPENSE'
GROUP BY TYPE_ID
ORDER BY count DESC
This is an aggregation query. Fortunately, SQLite supports CTEs, so you can just do something like this:
with t as (
<your query here>
)
select type, sum(value) as sumv
from t
group by type
order by sumv desc;
Even without the with clause, you could just use your query as a subquery.
You would, of course, use the appropriate column names in the query.
#CL. Your response led me down the correct path, for those interested here is the resulting query that achieved what I was after:
String selectQuery = "SELECT " + KEY_LABEL_ID + ", " + " SUM(" + KEY_AMOUNT + ") as total, " + KEY_TYPE_ID + " " +
"FROM (" +
"SELECT " + KEY_LABEL_ID + ", " + KEY_AMOUNT + ", " + KEY_TYPE_ID + " " +
"FROM " + TABLE_TRANSACTIONS + " " +
") as trans_table " +
"WHERE " + KEY_TYPE_ID + " = " + TagData.TYPE_EXPENSE + " " +
"GROUP BY " + KEY_LABEL_ID + " " +
"ORDER BY total DESC";
Lets assume, that we have some 2 tables in SQLite: TBL_PRODUCT and TBL_PRODUCT_ALIASES. Now, I want to query some data from joined two tables:
String sql = "SELECT " + TBL_PRODUCT + "." + C_PROD_PKEY_ID + ", " + TBL_PRODUCT_ALIASES + "." + C_PROD_ALIASES_PKEY_ID +
" FROM " + TBL_PRODUCT + " LEFT JOIN " + TBL_PRODUCT_ALIASES + " ON " + TBL_PRODUCT + "." + C_PROD_PKEY_ID + " = " + TBL_PRODUCT_ALIASES + "." + C_PROD_ALIASES_PKEY_ID +
" WHERE " + C_PROD_SERVER_ID + " = ? LIMIT 1";
Cursor cursor = SQLiteDataHelper.getInstance().rawQuery(sql, new String[] {"" + js_CartProduct.getLong("prod_id")});
Thats works great without any problem. And then I want to acquire some data from the returned cursor:
if (cursor.getCount() > 0) {
cursor.moveToFirst();
Long prodId = cursor.getLong(cursor.getColumnIndexOrThrow(TBL_PRODUCT + "." + C_PROD_PKEY_ID));
//... Some other code
}
Now, here is the problem: C_PROD_PKEY_ID and C_PROD_ALIASES_PKEY_ID are in the real world the same Strings: "_id". And as the result getLong() returns long not from the needed column of cursor.
How should I correctly address to the needed column? Are there other methods besides using AS in sql query OR/AND using definite numbers in cursor.getLong(0) instead of cursor.getLong(cursor.getColumnIndexOrThrow(TBL_PRODUCT + "." + C_PROD_PKEY_ID))?
Update:
cursor.getColumnNames() returns this: [_id, _id].
