I’ve recently encountered a peculiar issue and was hoping to get some insights or solutions from this community.
Background: I have a database table with several columns. For optimization purposes, I have created separate secondary indexes on a few of these columns, and they work perfectly fine. However, I’ve run into a problem with the latest column I indexed.
The Issue: After creating an index on a specific column (let’s call it
ColumnX), when I perform a search based on that column, it returns no results. The strange part is, I am certain that the data I’m searching for exists in the table because when I search for the same data in a different field (say
ColumnY), I can locate the desired entry.
Steps Taken So Far:
- Verified that the index was created successfully without any errors.
- Ensured that the data I’m searching for in
ColumnXdoes exist in the table.
- Checked the query to ensure that there aren’t any typos or logical errors.
- Reindexed the column to see if it resolves the issue (it didn’t).
- Version: 3.0.8
- Index Query:
CREATE INDEX idx_db1_cl1 ON main.db1 (cl1);
- Query Used:
SELECT * FROM main.db1 WHERE cl1 = '0123';
I’m baffled as to why this is happening, especially since I’ve indexed other columns in the same manner without any issues. Has anyone else encountered this problem or have any suggestions on how to fix it? Any help or insights would be greatly appreciated.
Thank you in advance!
