MySQL的 - LOAD DATA LOCAL INFILE - 問題如果數據庫表名有連字符

Question

我在PHP中使用腳本中

$sqlQueryImport = "LOAD DATA LOCAL INFILE '".$fileNewDataImportInDB."' INTO TABLE " .$sqlTableName 
     . " CHARACTER SET UTF8" 
     . " FIELDS TERMINATED BY ';'" 
     . " ENCLOSED BY '\"'"    
     . " LINES TERMINATED BY '\n'"; 

我總是錯誤導入CSV到數據庫表中：

You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'tbl-test' CHARACTER SET UTF8 FIELDS TERMINATED BY ';' ENCLOSED BY '"' LINES T' at line 1"

爲了測試它，我直接在phpmyadmin中將csv導入到數據庫表中並且它可以正常工作。

然後我將數據庫表名「tbl-test」更改爲「tbl_test」並且沒有錯誤。

不允許在數據庫表名中使用「 - 」嗎？或者我必須爲它編寫一個特殊的代碼？

Answer 1

您可以嘗試使用反引號轉義表名稱。所以，你的LOAD DATA聲明是這樣的：

LOAD DATA LOCAL INFILE someFile.csv INTO TABLE `tbl-test` 
CHARACTER SET UTF8 
FIELDS TERMINATED BY ';' 
ENCLOSED BY '\"' 
LINES TERMINATED BY '\n' 

的完整代碼：

$sqlQueryImport = "LOAD DATA LOCAL INFILE '".$fileNewDataImportInDB."' INTO TABLE `" .$sqlTableName 
     . "` CHARACTER SET UTF8" 
     . " FIELDS TERMINATED BY ';'" 
     . " ENCLOSED BY '\"'"    
     . " LINES TERMINATED BY '\n'";
