@Rocky attempting to drop and recreate a partition and getting this error SQL Error [1507] [HY000]: Error in list of partitions to [p20260714]

Based on the error code 1507 (HY000) in StarRocks, this error specifically means you are attempting to drop a partition that does not exist, and you haven't included the

IF EXISTS

clause in your statement. Why this is happening The error message

Error in list of partitions to [p20260714]

(where

p20260714

is your partition name) occurs when the system attempts to resolve the partition you've targeted for deletion but cannot find it in the table metadata. How to resolve it 1. Check if the partition exists Run the following command to see the actual list of partitions and their names:

sql
SHOW PARTITIONS FROM your_table_name;

Verify that the name

p20260714

is spelled correctly and exists in the

PartitionName

column. 2. Use the

IF EXISTS

clause To avoid this error (especially in scripts where you are dropping and recreating), add

IF EXISTS

to your

DROP

statement. This ensures the command succeeds even if the partition is already gone:

sql
ALTER TABLE your_table_name DROP PARTITION IF EXISTS p20260714;

3. Check for Batch Drop Syntax (v3.4+) If you are trying to drop multiple partitions at once, ensure you are using the correct parentheses syntax:

sql
-- Correct
ALTER TABLE your_table_name DROP PARTITIONS (p20260713, p20260714);

-- Incorrect (may cause list resolution errors)
ALTER TABLE your_table_name DROP PARTITION p20260713, p20260714;

Note on recreating If you successfully drop the partition and then fail to recreate it (e.g., with an "Already Exists" error), keep in mind that: * Trash Interval: By default, dropped partitions are moved to the "Trash" for 24 hours. While they are in the trash, you can't create a new partition with the same range/values if they overlap, but you can usually create one with the same name once the metadata is cleared. * Force Drop: If you want to skip the trash and immediately clear the metadata, use the

FORCE

keyword (use with caution):

sql
    ALTER TABLE your_table_name DROP PARTITION p20260714 FORCE;
