mysql - 从 Infobright 上的脚本运行时加载 DATA INFILE 错误

Question

在 infobright 提示符下运行时，查询执行得非常好：

mysql> LOAD DATA INFILE '/tmp/test.agg' IGNORE INTO TABLE tb_message_content FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"' ESCAPED BY '\\'LINES TERMINATED BY '\n';
Query OK, 2 rows affected

但是，从 shell 脚本运行时，相同的查询会出错：这就是脚本解释查询的方式

mysql -u amr_ts_scripts -pamr_ts_scripts MVR4_ETL_DB -S /tmp/mysql-ib.sock -N -e 
$'LOAD DATA INFILE \'/tmp/test.agg\'
 IGNORE INTO TABLE tb_message_content \n      
 FIELDS TERMINATED BY \',\' \n             
 OPTIONALLY ENCLOSED BY \'"\' \n             
 ESCAPED BY \'\\\'\n      
 LINES TERMINATED BY \'\\n\';'

引用的错误是：

ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''\'
      LINES TERMINATED BY ''' at line 4
PAGER set to stdout

谁能指出我面临的问题？

Answer 1

stmt="LOAD DATA INFILE '$1' IGNORE INTO TABLE $2 FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"' ESCAPED BY '\\\\' LINES TERMINATED BY '\n';

脚本中的上述语句有效，因为需要 ESCAPED BY '\\' 来转义每个 '\'。
