How to preview data before importing?

Previewing data files can detect problems such as format errors, field misalignment or missing values ??in advance. The specific methods include: 1. Use Excel, GoogleSheets or text editor to view the first few lines and check the table header alignment, garbled code, empty values ??and separator consistency; 2. Use database tools such as MySQLWorkbench to identify field types, adjust mappings and discover encoding conflicts; 3. Read some data through Python scripts (such as Pandas) to verify structure, missing values ??and blank rows; 4. Pay attention to hidden problems such as encoding format, line break differences and invisible characters, and use special tools to troubleshoot.

How to use the Schema Transfer feature?

SchemaTransfer is a function used to migrate database structure rather than data, and is suitable for development, testing, deployment and other scenarios. Its operation process includes: connecting the source and the target database, selecting migration functions, mapping objects, previewing and executing SQL scripts. When using it, you need to pay attention to character set, engine consistency, dependency objects, permission issues and incremental update settings. It is recommended to simulate and run first to avoid errors.

How to manage partitions in Navicat?

Database partitioning is to split large tables into small parts to improve performance and management efficiency. Common types include: 1. RANGE partition (by range), 2. LIST partition (by list), 3. HASH partition (determined by hash value), 4. KEY partition (using internal algorithm). The steps to create a partition in Navicat are: connect to the database, right-click the target table and select "Design Table", configure the partition type and expression in advanced settings and save the execution. Modifying existing partitions can be achieved by viewing the DDL structure, exporting modified table creation statements, or using SQL commands. Notes include: the partition field should be part of the primary key to avoid too many partitions and should not change the partition structure frequently.

How to compare database data?

To compare database data, first clarify the comparison target, such as inter-table, master-slave, or cross-database comparison, and determine the scope and unique identifier. Secondly, small data tables can be manually compared through SQL statements such as EXCEPT, FULLOUTERJOIN, etc. Third, use professional tools such as MySQLWorkbench, Navicat, and pt-table-sync to improve efficiency and automate processing. Finally, pay attention to the field order and null value issues to avoid misjudgment. Mastering these methods can effectively ensure data consistency.
