I have a query which will return one row. Is there any way I can find the row index of the row I'm querying when the table is sorted?
I've tried rowid
but got #582 when I was expecting row #7.
Eg:
CategoryID Name
I9GDS720K4 CatA
LPQTOR25XR CatB
EOQ215FT5_ CatC
K2OCS31WTM CatD
JV5FIYY4XC CatE
--> C_L7761O2U CatF <-- I want this row (#5)
OU3XC6T19K CatG
L9YKCYAYMG CatH
XKWMQ7HREG CatI
I've tried rowid with unexpected results:
SELECT rowid FROM Categories WHERE CategoryID = 'C_L7761O2U ORDER BY Name
EDIT: I've also tried J Cooper's suggestion (below), but the row numbers just aren't right.
using (var cmd = conn.CreateCommand()) {
cmd.CommandText = string.Format(@"SELECT (SELECT COUNT(*) FROM Recipes AS t2 WHERE t2.RecipeID <= t1.RecipeID) AS row_Num
FROM Recipes AS t1
WHERE RecipeID = 'FB3XSAXRWD'
ORDER BY Name";
cmd.Parameters.AddWithValue("@recipeId", id);
idx = Convert.ToInt32(cmd.ExecuteScalar());
In the cell, type the formula = ROW() and press enter. The ROW function returns the row number 7 as given in the argument. Similarly, if you try writing = ROW(M9), the formula returns the row number 9 as the row number is already given in the argument. It's as easy as that.
ROW_NUMBER function is a SQL ranking function that assigns a sequential rank number to each new record in a partition. When the SQL Server ROW NUMBER function detects two identical values in the same partition, it assigns different rank numbers to both.
Here is a way to get the row number in Sqlite:
SELECT CategoryID,
Name,
(SELECT COUNT(*)
FROM mytable AS t2
WHERE t2.Name <= t1.Name) AS row_Num
FROM mytable AS t1
ORDER BY Name, CategoryID;
