Question

I am trying to import SQL file attached in the module to create Personal Finance tables in Cloud Database but I am getting below error: 
 
 -- --------------------------------------------------------

--
-- Table structure for table `PF_ACCOUNT`
--

CREATE TABLE `PF_ACCOUNT` (
 `ACCOUNT_ID` int(11) NOT NULL,
 `TYPE_ID` int(11) DEFAULT NULL,
 `BALANCE` double DEFAULT NULL,
 `NAME` varchar(255) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb3 COLLATE=utf8mb3_general_ci;

MySQL said: 
 #1173 - This table type requires a primary key

Can anyone help me here.

hi bhuvneshg0001 database table must have a primary key for the Option to insert, update, restore, or delete data from a database table. CREATE TABLE `PF_ACCOUNT` (
 `ACCOUNT_ID` int(11) NOT NULL,
 `TYPE_ID` int(11) DEFAULT NULL,
 `BALANCE` double DEFAULT NULL,
 `NAME` varchar(255) DEFAULT NULL,
 PRIMARY KEY (`ACCOUNT_ID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb3 COLLATE=utf8mb3_general_ci

CREATE TABLE `PF_ACCOUNT` (
 `ACCOUNT_ID` int(11) NOT NULL AUTO_INCREMENT, 
 `TYPE_ID` int(11) DEFAULT NULL,
 `BALANCE` double DEFAULT NULL,
 `NAME` varchar(255) DEFAULT NULL,
 PRIMARY KEY (`ACCOUNT_ID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb3 COLLATE=utf8mb3_general_ci; bhuvneshg0001 You can't create table without primary key. I assumed that 'ACCOUNT_ID' will be a primary key. A primary key is a crucial element in a relational database table, and MySQL requires it for InnoDB tables (the engine you're using).
