**SQL Code Explanation**
|
|
==========================
|
|
|
|
### Table Update: `AddnlPROC`
|
|
|
|
This SQL code updates the values in the `WC2` column of the `AddnlPROC` table based on specific conditions.
|
|
|
|
```markdown
|
|
**UPDATE AddnlPROC SET AddnlPROC.WC2 = "304"**
|
|
|
|
* Updates the value in the `WC2` column.
|
|
* The new value is set to `"304"`.
|
|
|
|
**WHERE Condition**
|
|
--------------------
|
|
|
|
The update operation is restricted by a complex condition that must be met before any changes can be made to the `WC2` value. The condition is:
|
|
|
|
```markdown
|
|
**WHERE (((AddnlPROC.WC2)="330") AND ((AddnlPROC.WC3)="035") AND ((AddnlPROC.WC4)="035"))**
|
|
|
|
* Checks if the current value in the `WC2` column is equal to `"330"`.
|
|
* If this condition is not met, the update operation will be skipped.
|
|
* After verifying that `WC2` equals `"330"`, it checks if the current value in the `WC3` column equals `"035"` and also verifies that the value in the `WC4` column equals `"035"`.
|
|
* If either of these conditions is not met, the update operation will be skipped.
|
|
+ For example, if `WC2` is `"330"` but `WC3` or `WC4` has a different value than specified, the update will not proceed.
|
|
* Only when all three conditions are met (`WC2 = "330"`, `WC3 = "035"`, and `WC4 = "035"`), the update operation for the `WC2` column with the new value `"304"` is performed.
|
|
|
|
### Summary
|
|
|
|
This SQL code updates the `WC2` column in the `AddnlPROC` table to `"304"` only if three specific conditions are met:
|
|
- The current value of `WC2` equals `"330"`.
|
|
- The current value of `WC3` equals `"035"`.
|
|
- The current value of `WC4` equals `"035"`.
