If it is required to sort columns like this
1A 1a 10A 9B 21C 1C 1D
And Our desired Result is
1A 1C 1D 1a 9B 10A 21C
We can use casting, but casting will not sort 1A, 1B,1C properly. To overcome this issue we are first converting this column to binary and sorting the binary combined with tbl_column.
hehe,,, after doing some headbanging just did it with casting too... and using same logic... damn why I didnt thought of that.
- BIN Way
- ===================================
- SELECT
- tbl_column,
- BIN(tbl_column) AS binray_not_needed_column
- FROM db_table
- ORDER BY binray_not_needed_column ASC , tbl_column ASC
- -----------------------
- Cast Way
- ===================================
- SELECT
- tbl_column,
- CAST(tbl_column as SIGNED) AS casted_column
- FROM db_table
- ORDER BY casted_column ASC , tbl_column ASC
