How to compare two tables for differences in Navicat?

In Navicat, the difference between two tables is first used to identify row-level differences. 1. Open Navicat and connect to the database; 2. Select "Tools>Data Comparison"; 3. Specify source and target connections and tables; 4. Click to start analyzing the differences. The tool displays the differences line by line and generates synchronization scripts. If you are not sure whether the structure is consistent, you should first use the structure comparison function to check the column type, index, etc. The result view is divided into three parts: difference row, source row, and target row, which is easy to filter and view. Be careful when synchronizing operations to avoid accidentally overwriting data.

How to identify large tables in a database?

To find out the "big" tables in the database, the key is to check and calculate. First, use the system view or built-in function to view the physical storage size of the table. In PostgreSQL, you can query through pg_total_relation_size, and MySQL uses information_schema to obtain the table size; secondly, count the number of rows to determine the data volume of the table, and execute the COUNT(*) query, but it is recommended to use an estimation method for super-large tables; finally, based on the index usage and query frequency analysis performance impact, potential bottlenecks can be identified through slow query logs, pg_stat_statements and index scanning information. If the index is not effectively used and accessed frequently, the table may be a problem.
