Shell指令碼中執行mysql的幾種方式(轉)

對於自動化營運,諸如備份恢複之類的,DBA經常需要將SQL語句封裝到shell指令碼。本文描述了在Linux環境下mysql資料庫中,shell指令碼下調用sql語句的幾種方法,供大家參考。對於指令碼輸出的結果美化,需要進一步完善和調整。以下為具體的樣本及其方法。

1、將SQL語句直接嵌入到shell指令檔中

 

複製代碼 代碼如下:


--示範環境  
[[email protected] ~]# more /etc/issue  
CentOS release 5.9 (Final)  
Kernel \r on an \m  
  
[email protected][(none)]> show variables like ‘version‘;  
+---------------+------------+  
| Variable_name | Value      |  
+---------------+------------+  
| version       | 5.6.12-log |  
+---------------+------------+  
  
[[email protected] ~]# more shell_call_sql1.sh   
#!/bin/bash  
# Define log  
TIMESTAMP=`date +%Y%m%d%H%M%S`  
LOG=call_sql_${TIMESTAMP}.log  
echo "Start execute sql statement at `date`.">>${LOG}  
  
# execute sql stat  
mysql -uroot -p123456 -e "  
tee /tmp/temp.log  
drop database if exists tempdb;  
create database tempdb;  
use tempdb  
create table if not exists tb_tmp(id smallint,val varchar(20));  
insert into tb_tmp values (1,‘jack‘),(2,‘robin‘),(3,‘mark‘);  
select * from tb_tmp;  
notee  
quit"  
  
echo -e "\n">>${LOG}  
echo "below is output result.">>${LOG}  
cat /tmp/temp.log>>${LOG}  
echo "script executed successful.">>${LOG}  
exit;  
  
[[email protected] ~]# ./shell_call_sql1.sh   
Logging to file ‘/tmp/temp.log‘  
+------+-------+  
| id   | val   |  
+------+-------+  
|    1 | jack  |  
|    2 | robin |  
|    3 | mark  |  
+------+-------+  
Outfile disabled.  

 

2、命令列調用單獨的SQL檔案

 

複製代碼 代碼如下:


[[email protected] ~]# more temp.sql   
tee /tmp/temp.log  
drop database if exists tempdb;  
create database tempdb;  
use tempdb  
create table if not exists tb_tmp(id smallint,val varchar(20));  
insert into tb_tmp values (1,‘jack‘),(2,‘robin‘),(3,‘mark‘);  
select * from tb_tmp;  
notee  
  
[[email protected] ~]# mysql -uroot -p123456 -e "source /root/temp.sql"  
Logging to file ‘/tmp/temp.log‘  
+------+-------+  
| id   | val   |  
+------+-------+  
|    1 | jack  |  
|    2 | robin |  
|    3 | mark  |  
+------+-------+  
Outfile disabled.  

 

3、使用管道符調用SQL檔案

 

複製代碼 代碼如下:


[[email protected] ~]# mysql -uroot -p123456 </root/temp.sql  
Logging to file ‘/tmp/temp.log‘  
id      val  
1       jack  
2       robin  
3       mark  
Outfile disabled.  
  
#使用管道符調用SQL檔案以及輸出日誌  
[[email protected] ~]# mysql -uroot -p123456 </root/temp.sql>/tmp/temp.log  
[[email protected] ~]# more /tmp/temp.log  
Logging to file ‘/tmp/temp.log‘  
id      val  
1       jack  
2       robin  
3       mark  
Outfile disabled.  

 

4shell指令碼中MySQL提示符下調用SQL

 

複製代碼 代碼如下:


[[email protected] ~]# more shell_call_sql2.sh  
#!/bin/bash  
mysql -uroot -p123456 <<EOF  
source /root/temp.sql;  
select current_date();  
delete from tempdb.tb_tmp where id=3;  
select * from tempdb.tb_tmp where id=2;  
EOF  
exit;  
[[email protected] ~]# ./shell_call_sql2.sh  
Logging to file ‘/tmp/temp.log‘  
id      val  
1       jack  
2       robin  
3       mark  
Outfile disabled.  
current_date()  
2014-10-14  
id      val  
2       robin  

 

5shell指令碼中變數輸入與輸出

 

複製代碼 代碼如下:


[[email protected] ~]# more shell_call_sql3.sh  
#!/bin/bash  
cmd="select count(*) from tempdb.tb_tmp"  
cnt=$(mysql -uroot -p123456 -s -e "${cmd}")  
echo "Current count is : ${cnt}"  
exit   
[[email protected] ~]# ./shell_call_sql3.sh   
Warning: Using a password on the command line interface can beinsecure.  
Current count is : 3  
  
[[email protected] ~]# echo "select count(*) from tempdb.tb_tmp"|mysql -uroot-p123456 -s  
3  
  
[[email protected] ~]# more shell_call_sql4.sh  
#!/bin/bash  
id=1  
cmd="select count(*) from tempdb.tb_tmp where id=${id}"  
cnt=$(mysql -uroot -p123456 -s -e "${cmd}")  
echo "Current count is : ${cnt}"  
exit   
  
[[email protected] ~]# ./shell_call_sql4.sh   
Current count is : 1

下面附上通過shell命令列非互動操作資料庫的方法:

mysql -hhostname -Pport -uusername -ppassword -e 相關mysql的sql語句,不用在mysql的提示符下運行mysql,即可以在shell中操作mysql的方法。

#!/bin/bash

HOSTNAME="192.168.111.84"  #資料庫資訊

PORT="3306"

USERNAME="root"

PASSWORD=""

 

DBNAME="test_db_test"  #資料庫名稱

TABLENAME="test_table_test" #資料庫中表的名稱

 

#建立資料庫

create_db_sql="create database IF NOT EXISTS ${DBNAME}"

mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} -e"${create_db_sql}"

 

#建立表

create_table_sql="create table IF NOT EXISTS ${TABLENAME} ( namevarchar(20), id int(11) default 0 )"

mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e"${create_table_sql}"

 

#插入資料

insert_sql="insert into ${TABLENAME} values(‘billchen‘,2)"

mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e"${insert_sql}"

 

#查詢

select_sql="select * from ${TABLENAME}"

mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e"${select_sql}"

 

#更新資料

update_sql="update ${TABLENAME} set id=3"

mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e"${update_sql}"

mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e"${select_sql}"

 

#刪除資料

delete_sql="delete from ${TABLENAME}"

mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e"${delete_sql}"

mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e"${select_sql}"
