The tool currently supports MySQL, PostgreSQL, SQLite, and SQL Server. ### Can I use this for complex table renames? Yes, select the 'Rename Table' option and provide the current and new table names to generate the appropriate SQL. ### Does this tool execute the SQL on my database? No, this tool only generates the SQL script. You must manually execute the generated code in your database management interface. ### Is the generated SQL production-ready? The generated SQL follows standard syntax, but you should always review and test the script in a staging environment before applying it to production. ### Can I add multiple columns at once? Yes, you can define multiple columns in the 'Changes / Column Definition' field according to your database's specific syntax requirements. ## Related tools - [Database Backup Generator](https://elysiatools.com/en/tools/database-backup-generator): Generate SQL backup scripts for database tables - [Table Schema Generator](https://elysiatools.com/en/tools/table-schema-generator): Generate SQL table schema definitions - [Database Schema Diff](https://elysiatools.com/en/tools/database-schema-diff): Compare two database schemas and generate migration-oriented change reports - [SQL Query Builder](https://elysiatools.com/en/tools/sql-query-builder): Build simple SQL queries visually - [CSV to Database Migration Planner](https://elysiatools.com/en/tools/csv-to-database-migration-planner): Infer a relational schema from CSV data and generate create-table plus ALTER migration plans for PostgreSQL, MySQL, SQLite, or SQL Server - [XLSX SQL Insert Generator](https://elysiatools.com/en/tools/xlsx-sql-insert-generator): Read Excel headers and rows to generate SQL INSERT statements for bulk loading - [SQL Performance Analyzer](https://elysiatools.com/en/tools/sql-performance-analyzer): Analyze SQL queries for potential performance issues - [SQL Formatter](https://elysiatools.com/en/tools/sql-formatter): Format SQL queries ## Samples - [MySQL Database Samples](https://elysiatools.com/en/samples/mysql-database-samples): Sample MySQL database scripts with various complexity levels from simple tables to enterprise ERP systems - [Android Database Java Samples](https://elysiatools.com/en/samples/android-database-java): Android Java database examples including SQLite connection, SQL queries, and transaction processing - [Android Database Kotlin Samples](https://elysiatools.com/en/samples/android-database-kotlin): Android Kotlin database examples including SQLite connection, SQL queries, and transaction processing - [macOS Database Objective-C Samples](https://elysiatools.com/en/samples/macos-database-objectivec): macOS Objective-C database examples including SQLite CRUD operations, queries, transactions, and connection management ## Related content - [Database Schema Migration](https://elysiatools.com/en/hubs/database-schema-migration): Plan a safe database migration by normalizing source data, reviewing schema changes, validating relationships, and preparing rollback assets.
