📋 Table of Contents
The 'Calculate total row count' feature in DBeaver is malfunctioning, causing an error message that affects users who rely on this function. The error occurs when attempting to execute the query with a large number of rows, resulting in a syntax error.
This issue can be frustrating for users who need to quickly determine the number of rows in a table. Fortunately, DBeaver provides alternative methods to resolve this problem.
🔍 Why This Happens
- The primary cause of this error is a syntax issue related to the use of temporary tables in MySQL. When DBeaver attempts to calculate the total row count using the 'Calculate total row count' feature, it may not properly handle large datasets or temporary tables, leading to a syntax error.

Disable the 'Calculate total row count' feature and use an alternative method
