#!/bin/bash
#filename : create_db.sh
#use : create mysql database and tables

USER="root"
PASS="123456"
SOCKET="/data/mysqldata/3306/mysql.sock"

mysql -u $USER -p$PASS -S $SOCKET < /dev/null
create database students;
EOF

[ $? -eq 0 ] && echo Created DB || echo DB already exist
mysql -u $USER -p$PASS -S $SOCKET students < /dev/null
create table students(
id int,
name varchar(100),
mark int,
dept varchar(4)
);
EOF

[ $? -eq 0 ] && echo Created table students || echo Table students already exist

mysql -u $USER -p$PASS -S $SOCKET students <

腳本二、將數據插入數據表的腳本如下：
#!/bin/bash
#filename : write_to_db.sh
#use : read data from csv files and insert into mysql db

USER="root"
PASS="123456"
SOCKET="/data/mysqldata/3306/mysql.sock"

if [ $# -ne 1 ];
then
 echo $0 DATAFILE
 echo
 exit 2
fi
data=$1

while read line;
do
 oldIFS=$IFS
 IFS=,
 values=($line)
 values[1]="\"`echo ${values[1]} | tr ' ' '#' `\""
 values[3]="\"`echo ${values[3]}`\""

 query=`echo ${values[@]} | tr ' #' ', ' `
 IFS=$oldIFS
 
 mysql -u $USER -p$PASS -S $SOCKET students <

腳本三、查詢數據庫的腳本如下：
#!/bin/bash
#filename: read_db.sh
#use : read data from mysql db

USER="root"
PASS="123456"
SOCKET="/data/mysqldata/3306/mysql.sock"

depts=`mysql -u $USER -p$PASS -S $SOCKET students <

腳本按照順序執(zhí)行結果如下：
# chmod +x create_db.sh write_to_db.sh read_db.sh
# ./create_db.sh 
DB already exist
Table students already exist
# 
# ./write_to_db.sh studentdata.csv 
Wrote data into DB
# 
# ./read_db.sh
