SQL queries can be a source of frustration, especially when they don't seem to work as expected. This post addresses a frequent user error and walks through how to fix a SQL query related to counting entries by examining timestamp fields. If you've run into an error like "Incorrect syntax near unmatchedTranCounts", you're in the right place!

Common Mistakes

Missing spaces: The phrase tablesloadedtodayfrom should contain spaces before FROM. Proper spacing is crucial in SQL, as it delineates different components of the query.

Incorrect table alias reference: The reference to u before WHERE is not necessary. You should directly refer to the columns in the result set generated by the Common Table Expression (CTE) without needing a table alias as it's already defined.

The Corrected SQL Code

After identifying the issues, let's present the corrected SQL code clearly. Here’s the refined version of the SQL query:
