Can you help me with my code? Because I am creating a table logs for my project. So I include a TRIGGER in my table but there's an error with my sql code. Here's my sql codes.
CREATE TABLE `sales_category` (
`salescatid` BIGINT(20) UNSIGNED NOT NULL AUTO_INCREMENT,
`salescatname` VARCHAR(128) NOT NULL,
`salescatdesc` VARCHAR(512) NOT NULL,
UNIQUE INDEX `salescatname` (`salescatname`),
UNIQUE INDEX `salescatid` (`salescatid`)
)
COLLATE='latin1_swedish_ci'
ENGINE=InnoDB
CREATE TABLE `category_log` (
`action` ENUM('CREATE','UPDATE','DELETE') NULL DEFAULT NULL,
`id` INT(10) UNSIGNED NOT NULL,
`salescatname` VARCHAR(255) NOT NULL,
`salescatdesc` VARCHAR(255) NOT NULL,
INDEX `id` (`id`)
)
COLLATE='latin1_swedish_ci'
ENGINE=InnoDB;
//Here's the error: SQL error 1054: Unknown column 'id' in 'NEW'
DELIMITER #
CREATE TRIGGER ai_category
AFTER INSERT ON sales_category
FOR EACH ROW
BEGIN
INSERT INTO category_log(action,id,salescatname,salescatedesc)
VALUES('CREATE',NEW.id,NEW.salescatname,NEW.salescatdesc);
END;#
Please help me with this thanks. I can't spot where did I go wrong with my code.
Ok i found my error. I just rename the fields in category_log exactly the sa me as my sales_category table.

I am trying to convert the following sql into sqlite via sqlite3.exe but it keeps giving me this error:
Error: near line 1: near "SET": syntax error
I'm not entirely sure what this means or why. Here is my sql script:
SET SQL_MODE = 'NO_AUTO_VALUE_ON_ZERO',
time_zone = '+00:00';
CREATE TABLE `px` (
`x` int(11) NOT NULL,
`y` int(11) NOT NULL,
`colour` varchar(30) NOT NULL,
`time` varchar(30) NOT NULL,
`id` int(10) UNSIGNED NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
ALTER TABLE `px`
ADD PRIMARY KEY (`id`);
ALTER TABLE `px`
MODIFY `id` int(10) UNSIGNED NOT NULL AUTO_INCREMENT;
I'm sure i'm overlooking a simple syntax error. Any help would be much appreciated!
You can 't just run a MySQL script in SQLite. These are two different databases, whose syntax differ.
In SQLite, a relatively close syntax to the MySQL script would be:
CREATE TABLE `px` (
`x` integer NOT NULL,
`y` integer NOT NULL,
`colour` varchar(30) NOT NULL,
`time` varchar(30) NOT NULL,
`id` integer NOT NULL PRIMARY KEY AUTOINCREMENT
);

SQL query:
CREATE TABLE `usersinputs` (
`ID` int(11) NOT NULL,
`name` varchar(20) NOT NULL,
`email` varchar(30) NOT NULL,
`message` varchar(100) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1
MySQL said: Documentation
#1050 - Table 'usersinputs' already exists
Your error says it all. There is already a table named as userinputs in your database. You need to create a table with a different name or if there is any datatype change or any other alteration to the table then you need to ALTER the table.
Instead of creating a table which already exists try one with another name.
You can however alter or check if the table exists:
CREATE TABLE IF NOT EXISTS `usersinputs` (
`ID` int(11) NOT NULL,
`name` varchar(20) NOT NULL,
`email` varchar(30) NOT NULL,
`message` varchar(100) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1
The error is due to the table usersinputs is already exists in your database.
If you really want to CREATE a new table with the different columns and data types you can DROP the existing table and CREATE the new table by DROP TABLE IF EXISTS `usersinputs`;
So your code will be:
DROP TABLE IF EXISTS `usersinputs`;
CREATE TABLE `usersinputs` (
`ID` int(11) NOT NULL,
`name` varchar(20) NOT NULL,
`email` varchar(30) NOT NULL,
`message` varchar(100) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1
Or simply want to change any column name or data type use ALTER TABLE
I am new to MySQL and am uploading a database for the first time. I am not uploading the data, just the columns for now. The issue is that I get an error for every line of code provided:
#1064 - You have an error in your SQL syntax;
I can understand if I was getting the message for just one or two lines of the code, but I am beginning to think I misformatted all the database file since I'm getting that error message for every line.
I previously changed the primary/foreign keys
CONSTRAINT `PurchasePK` PRIMARY KEY (`P_ORDERNO`)
CONSTRAINT `PurchaseFK` FOREIGN KEY (`SUPPLY_CODE`)
to: P_ORDERNO int(5) NOT NULL auto_increment PRIMARY KEY,
And still get errors.
I would appreciate if someone took a look at the contents of the .sql file below and let me know if there is something I am missing that is giving me consistent errors.
-- Table structure for table `Purchase`
CREATE TABLE IF NOT EXISTS `Purchase` (
`P_ORDERNO` int(5) NOT NULL auto_increment PRIMARY KEY,
`SUPPLY_CODE` int(5) NOT NULL auto_increment FOREIGN KEY,
`P_ORDER_DATE` timestamp NOT NULL,
`P_ORDER_AMT` int(5) NOT NULL,
`SUPPLY_DESC` varchar(50) NULL,
`SUPPLY QTY` int(5) NOT NULL,
);
ENGINE = InnoDB;
-- Table structure for table `Vendor`
CREATE TABLE IF NOT EXISTS `Vendor` (
`VENDORNO` int(5) NOT NULL auto_increment PRIMARY KEY,
`VENDOR_NAME` varchar(50) NULL,
`VENDOR_STREET` varchar(50) NULL,
`VENDOR_CITY` varchar(50) NULL,
`VENDOR_STATE` varchar(2) NULL,
`VENDOR_ZIP` varchar(3) NULL,
`VENDOR_AREA_CODE` varchar(5) NULL,
`VENDOR_PHONE` varchar(10) NULL,
);
ENGINE = InnoDB;
-- Table structure for table `Supply`
CREATE TABLE IF NOT EXISTS `Supply` (
`SUPPLY_CODE` int(5) NOT NULL auto_increment PRIMARY KEY,
`SUPPLY_DESC` varchar(50) NULL,
`SUPPLY QTY` int(5) NOT NULL,
);
ENGINE = InnoDB;
You have trailing commas
`SUPPLY QTY` int(5) NOT NULL,
^---here
);
in each of the table definitions. That makes the DB server expect another field definition, but instead it runs into );
I'm new to sql, currently I am using phpMyAdmin via XAMP, I think that uses mysql so correct me if I'm wrong by saying that. Anywhos, I'm trying to import a schema.sql data file into my database I created called "test" but I got an error upon importing it:
It says
Import has been successfully finished, 1 queries executed.
(schema.sql)
But then it also gives me an error message:
CREATE TABLE `population` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`location` varchar(150) NOT NULL,
`slug` varchar(150) NOT NULL,
`population` int(10) unsigned NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8
MySQL said: Documentation
1075 - Incorrect table definition; there can be only one auto column and it must be defined as a key
and :
Notice in .\import.php#704 Undefined variable: import_text Backtrace
I'm not sure what the issue is. The database I created is completely and has nothing in it.
Column id is the auto-column in question; auto-columns need to be defined as a key, for example as a unique key or a primary key. In your case, a primary key is a good idea because - well, it's your id-column.
CREATE TABLE `population` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`location` varchar(150) NOT NULL,
`slug` varchar(150) NOT NULL,
`population` int(10) unsigned NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
Please have a look at the following code
INSERT INTO `test2.key_word` SELECT * from `test.key_word`
I am using PHPMyAdmin. This query simply gives the error No Database Selected when run inside the server 127.0.0.1 area. If I run this inside query inside the SQL Query in test2.key_word, then it says Table 'test2.test2.key_word' doesn't exist.
Below is how the test.key_word table is created
CREATE TABLE `key_word` (
`primary_key` bigint(20) NOT NULL AUTO_INCREMENT,
`indexVal` int(11) NOT NULL,
`hashed_word` char(3) NOT NULL,
PRIMARY KEY (`primary_key`),
KEY `hashed_word` (`hashed_word`,`indexVal`)
) ENGINE=InnoDB AUTO_INCREMENT=28570982 DEFAULT CHARSET=latin1
Below is how the test2.key_word table is created
CREATE TABLE `key_word` (
`primary_key` bigint(20) NOT NULL,
`indexVal` int(11) NOT NULL,
`hashed_word` char(3) NOT NULL,
PRIMARY KEY (`primary_key`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1
Why this is not getting copied? Please help.
Use as per below, you have made db and tablename as a single name encsoling by db.table.
INSERT INTO test2.key_word SELECT * from test.key_word;
Note: Make sure no of columns should be same in source and target table.
