好的,請參考下面的程式碼,然後我會提出我的問題。
#!/usr/bin/bash
#scirpt to connect with db
master_db_user='root'
master_db_passwd='123'
master_db_port='3306'
master_db_host='localhost'
master_db_name='uppcldashboard'
Now=$(date +"%d-%m-%Y")
date=$(date +"%F")
#Preparing script
#SQL_Query='select * from test_table;'
#MySql Command to connect to a database
#mysql -u$master_db_user -p$master_db_passwd -D$master_db_name -e "select * from uppcl_amount_details into outfile '/created_files/uppcl.csv' fields terminated by ',' lines terminated by '\n';"
mysql -u$master_db_user -p$master_db_passwd -D$master_db_name -e "select * from uppcl_amount_details where posting_date='$date' into outfile '/created_files/uppcl.csv' fields terminated by ',' lines terminated by '\n';"
mv /created_files/uppcl.csv /created_files/offline_collection$Now.csv
sed -i "1i id","Cashier_id","Cheque_no","collection_amount","collection_type","Posting_date","Discom","Division_Code","Division_Name","Head_cashier_id","ref_3","ref_4","ref_5","ref_6","ref_7","ref_8","Tran_Date","Status","Posting_Updated_Date" /created_files/offline_collection$Now.csv
echo "End of the Script"
好的,我可以取得日期為 2020-04-15 00:00:00 的日期,但我無法取得日期為 2020-04-15 12:12:10 的資料。
所以我在想是否有一種方法可以從資料庫中以這種格式 %Y-%m-%d 獲取數據,然後使用我的日期變數($Now)來提取所有數據。
有什麼辦法嗎
盡快需要協助。
謝謝和問候, 薩加爾·曼達爾

預設情況下,如果我們只為日期時間參數提供日期值,則sql 將採用。使用通配符列出該日期以來的所有日誌。
嘗試作為
posting_date LIKE '$date%'
