freeTDS bash:在Microsoft SQL Server中执行sql查询

Question

我可以通过Mint Linux VM使用freeTSD和命令行连接到Microsoft SQL Server 2008实例,以在其上执行sql语句.现在我想在bash脚本中自动执行此操作.我能够成功登录我的bash脚本:

TDSVER=8.0 tsql -H servername -p 1433 -D dbadmin -U domain\\Administrator -P password

然后我有我的SQL查询:

USE dbname GO delete from schema.tableA where ID > 5 GO delete from schema.tableB where ID > 5 GO delete from schema.tableC where ID > 5 GO exit

这通过freeTSD命令行手动执行时有效,但是当我放入bash文件时则不行.我关注这篇文章:freeTSD&bash.

这是我的bash脚本示例:

echo "USE dbname GO delete from schema.tableA where userid > 5 go delete from schema.tableB where userid > 5 go delete from schema.tableC where ID > 5 GO exit" > tempfile | TDSVER=8.0 tsql -H servername -p 1433 -D dbname -U domain\\Administrator -P password < tempfile

bash脚本的输出是:

locale is "en_US.UTF-8"
locale charset is "UTF-8"
Default database being set to sbdb
1> 2> 3> 4> 5> 6> 7> 8> 

然后我的脚本的其余部分被执行.

有人能给我一步一步解答我的问题吗？

我不确定你的示例如何工作。

这是我的 bash 脚本示例：

echo "USE dbname .... exit" > tempfile | TDSVER=8.0 tsql -H servername -p 1433 -D dbname -U domain\\Administrator -P password < tempfile
# ------------------------------------^^^^ ---- pipe char?

尝试使用“;” 字符。

echo "USE dbname .... exit" > tempfile ; TDSVER=8.0 tsql -H servername -p 1433 -D dbname -U domain\\Administrator -P password < tempfile
# ------------------------------------^^^^ ---- semi-colon

更好的是，使用 shell 的“此处文档”。

TDSVER=8.0 tsql -H servername -p 1433 -D dbname -U domain\\Administrator -P password <<EOS
     USE dbname 
     GO 
     delete from schema.tableA where userid > 5 
     go 
     delete from schema.tableB where userid > 5 
     go 
     delete from schema.tableC where ID > 5 
     GO 
     exit
  EOS

IHTH。

当前命令行输入：

echo "delete from table where userid > 5
go
delete from table where userid > 5
go
delete from table where ID > 5
GO
exit" < /tmp/tempfile; TDSDUMP=/tmp/freetds.log TDSVER=8.0 tsql -H servername -p 1433 -D dbname -U Administrator -P password <<EOS
