利用Shell將MySQL數據表導出爲csv文件
完整的Shell代碼以下：mysql
#!/bin/bash
MYSQL=`which mysql`
#show databases in mysql
echo "database in mysql:"
echo "*******************"
$MYSQL -u root -p****** << EOF
show databases;
EOF
echo "*******************"
#choose a database
read -t 60 -p "choose a database:" database
#show tables in the database
echo "tables in $database"
echo "*******************"
$MYSQL -u root -p****** << EOF
use $database
show tables;
EOF
echo "*******************"
#choose a table
read -t 60 -p "choose a table:" table
statement="use $database;select * from $table;"
#write the table into 1.log file
$MYSQL -u root -p****** >1.log << EOF
$statement
EOF
echo "Downloading $table from $database in mysql..."
sleep 1
echo "now converting it to csv file..."
sleep 1
#cat the 1.log file and convert it to csv file
cat 1.log | while read line
do
echo $line | tr " " ","
done > $database"_"$table.csv
sleep 1
#remove the temporal file 1.log
rm -rf 1.log
#echo the infomation
echo "Convert $table into $database"_"$table.csv."
sleep 1
echo "Done successfully!Please check the file!"
其中$MYSQL -u root -p******的「******」爲mysql登錄密碼。
