通过以表名作为参数并执行配置单元查询来编写shell脚本

Question

我在尝试构建以table_name作为参数并运行以下配置单元查询的shell脚本。

INSERT OVERWRITE DIRECTORY '/data/table_name' 
row format delimited 
FIELDS TERMINATED BY ',' 
SELECT * FROM table_name 

Answer 1

也许你需要它：

#!/bin/bash 
if [ -z "$1" ]; then exit 1; fi  
printf -v TAB "%q" "$1" 
/usr/bin/mysql -NBe "INSERT OVERWRITE DIRECTORY '/data/table_$TAB' row format delimited FIELDS TERMINATED BY ',' SELECT * FROM $TAB"
