Dear all,
I have below table
+-----+--------------------+---------------------+
| id | db |cr |
+-----+--------------------+---------------------+
|1 | | 200 |
|2 | 100 | |
|3 | 100 | |
|4 | 150 | |
|5 | | 200 |
I Would like to calc that balance, and look like
+-----+--------------------+---------------------+-----------+
| id | db |cr | bal |
+-----+--------------------+---------------------+-----------+
|1 | | 200 |200 |
|2 | 100 | |100 |
|3 | 100 | |0 |
|4 | 150 | |-150 |
|5 | | 200 |50 |
What can I do to get result like that
