It looks like you're working on a SQL script for an MMORPG database, specifically for the game SRO (Shaiya). The script is intended to perform certain actions based on specific conditions. Let's break down the script and ensure it is complete and correct. Explanation of the Script 1. Condition Check: - `@code2` should match a pattern: `'item_ch_' + @itemcodeprefix + '_a_rare'`. - `@optlevel` should be greater than or equal to `1 - @ck`. - `@cl1` should be `24670`. - `@cl2` should be `24669`. - `@clsl1` should be greater than `1`. - `@clsl2` should be greater than `1`. 2. Actions if Conditions are Met: - Retrieve the character name from the `_char` table. - Update the `_inventory` table to set `itemid` to `0` for a specific slot (`slot=13`) for the given character. - Decrease the `data` field in the `_items` table for items in slot `14` of the character's inventory. - The last part of the script seems incomplete, so we need to complete it. Complete Script ```sql if ( @code2 like 'item_ch_' + @itemcodeprefix + '_a_rare' and @optlevel >= 1 - @ck and @cl1 = 24670 and @cl2 = 24669 and @clsl1 > 1 and @clsl2 > 1 ) begin -- Retrieve the character name select @charname = charname16 from _char where charid = @charid; -- Update the inventory to set itemid to 0 for slot 13 update _inventory set itemid = 0 where charid = @charid and slot = 13; -- Decrease the data field in the _items table for items in slot 14 update sro_vt_shard.._items set data = data - 1 where id64 in (select itemid from sro_vt_shard.._inventory where slot = 14 and charid = @charid); -- If there are more actions to perform, add them here end ``` Additional Considerations 1. Error Handling: It might be useful to add error handling to ensure that the script runs smoothly and logs any issues. 2. Transaction Management: If these operations are critical, consider wrapping them in a transaction to ensure atomicity. 3. Logging: Logging the actions performed can be helpful for debugging and auditing. Example with Transaction and Logging ```sql begin transaction; if ( @code2 like 'item_ch_' + @itemcodeprefix + '_a_rare' and @optlevel >= 1 - @ck and @cl1 = 24670 and @cl2 = 24669 and @clsl1 > 1 and @clsl2 > 1 ) begin -- Retrieve the character name select @charname = charname16 from _char where charid = @charid; -- Log the action insert into log_table (action, charid, charname, timestamp) values ('Inventory Update', @charid, @charname, getdate()); -- Update the inventory to set itemid to 0 for slot 13 update _inventory set itemid = 0 where charid = @charid and slot = 13; -- Decrease the data field in the _items table for items in slot 14 update sro_vt_shard.._items set data = data - 1 where id64 in (select itemid from sro_vt_shard.._inventory where slot = 14 and charid = @charid); -- Commit the transaction commit transaction; end else begin -- Rollback the transaction if conditions are not met rollback transaction; end ``` This script ensures that all actions are performed atomically and logs the actions for future reference. Adjust the `log_table` and its columns as per your database schema. [2024-10-22 11:26:02 | AI写代码神器 | 969点数解答]
