=== 6. SQL 檔案 === SQL 檔案:關聯式資料庫的匯出格式,內容為多列的 SQL 語法(如 {{kbd | key=<nowiki>INSERT INTO ...</nowiki>}}),可直接匯入至資料庫。 SQL 檔案本身沒有筆數上限,格式本身只是純文字,限制同樣來自開啟或匯入它的工具。 常見問題是 * (1) 檔案過大:大量資料匯出後動輒數 GB,用文字編輯器開啟會導致當機或無回應。 * (2) 跨資料庫相容性:不同資料庫引擎(如 MySQL、PostgreSQL、SQLite)的 SQL 語法有差異,從 A 引擎匯出的 .sql 檔案,未必能直接匯入另一個引擎。可參考 [[排除_MySQL_技術疑難問題#從_MySQL_資料轉移至_MSSQL | 從_MySQL_資料轉移至_MSSQL]] 如果只需要搬移資料而非還原完整資料庫結構,建議改用 CSV 或 Parquet,避免上述相容性問題。
