I was running this SQL create table in access 2016 database but I get syntax error in CONSTRAINT clause. It appears correct to me. What may be the error in the constraint clause.
CREATE TABLE COMPUTER(
SerialNumber Number NOT NULL,
Make Text(12) NOT NULL,
Model Text(24) NOT NULL,
ProcessorType Text(24) NULL,
ProcessorSpeed Number NOT NULL,
MainMemory Text(15) NOT NULL,
DiskSize Text(15) NOT NULL,
primary key(SerialNumber),
CONSTRAINT MAKE_CHECK (Make IN ('Dell', 'Gateway', 'HP', 'Other')),
CONSTRAINT SPEED_CHECK CHECK(ProcessorSpeed BETWEEN 1.0 AND 4.0))
Use the correct syntax:
CONSTRAINT MAKE_CHECK CHECK(Make IN ('Dell', 'Gateway', 'HP', 'Other')),

I am trying to create a table which references two other tables that I have planned to make, but have not made yet. I am wondering if that is the issue here or if there is a syntax error that I am missing. If anyone can help me out it would be greatly appreciated
mysql> CREATE TABLE items (
items$id INT NOT NULL AUTO_INCREMENT,
sales$id INT NOT NULL AUTO_INCREMENT,
img$id INT NOT NULL AUTO_INCREMENT,
name VARCHAR(255) NOT NULL,
desc VARCHAR(255) NOT NULL,
PRIMARY KEY(items$id),
FOREIGN KEY(sales$id) REFERENCES sales(sales$id),
FOREIGN KEY(img$id) REFERENCES image(img$id)
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'desc VARCHAR(255) NOT NULL,
PRIMARY KEY(items$id),
FOREIGN KEY(sales$id) REFEREN' at line 6
I tried to remove the references, as in just do 'FOREIGN KEY(sales$id)' and 'FOREIGN KEY(img$id)' to see if that would work (I am new to mysql), but that also did not work. Any help is appreciated.
The problem is your field name: desc
desc is a keyword in mysql see here
Your sql would be better like this:
CREATE TABLE items ( items$id INT NOT NULL AUTO_INCREMENT, sales$id INT NOT NULL AUTO_INCREMENT, img$id INT NOT NULL AUTO_INCREMENT, name VARCHAR(255) NOT NULL, descr VARCHAR(255) NOT NULL, PRIMARY KEY(items$id),
FOREIGN KEY(sales$id) REFERENCES sales(sales$id),
FOREIGN KEY(img$id) REFERENCES image(img$id))
Ps: you missed closing bracket ')' at the end of your sql query.
So I'm trying to migrate a table from MySQL to MSSQL (sql server migration assistant MySQL), but I get this error:
Migrating data...

I've just copied three rows from my table, and this is what they look like:
'1', 'Pump# TimeToService', NULL, NULL, 'A general test case comment ...', '0'
'2', 'Config.SlaveMinimumReplyDelay', NULL, NULL, NULL, '0'
'3', 'Config.RESERVED', NULL, NULL, NULL, '0'
If you are wondering how the colons in the MySQL table is setup, here you go:
Is is because right, left and comment can be null?
DDL of table
CREATE TABLE `testcase` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`TestCaseName` varchar(150) DEFAULT NULL,
`Left` int(11) DEFAULT NULL,
`Right` int(11) DEFAULT NULL,
`Comment` text,
`Hidden` tinyint(4) NOT NULL DEFAULT '0',
PRIMARY KEY (`id`),
UNIQUE KEY `Unique` (`Left`,`Right`)
) ENGINE=InnoDB AUTO_INCREMENT=10580 DEFAULT CHARSET=utf8
Had to remove the Unique part, since their are only NULL.
ALTER TABLE `testreportingdebug`.`testcase`
DROP INDEX `Unique`;
If you want the strict equivalent in SQL Server of your MySQL table you must create it like this :
CREATE TABLE testcase (
id int NOT NULL IDENTITY PRIMARY KEY,
TestCaseName varchar(150),
[Left] int,
[Right] int,
Comment VARCHAR(max),
[Hidden] tinyint DEFAULT 0,
);
CREATE UNIQUE INDEX X_testcase_right_left
ON testcase ([Left], [Right])
WHERE [Left] IS NOT NULL
AND [Right] IS NOT NULL;
By the way, column names "Right", "left", "hidden" are SQL / MS SQL Server reserved words and should not be used at anytime for SQL identifiers (table name, colum name, proc name...)

I made a EER diagram and I am trying to Forward Engineer it but I get this error and I can't find the mistake.

This is mysql version issue Remove the VISIBLE. and run the code manually . Or update mysql server and the client into same version .
(Wallets_idWallets ASC) VISIBLE into (Wallets_idWallets ASC)
can you add engine

Before you forward engineering tick the below options and continue the process,
Go to the option section > Under the set options for Database to be created
Skip creation of foreign keys
Skip creation of Indexes as well
generate separate create index statements
Generate Insert statement for table
And continue the forward engineering process.
Getting an error in the SQL script while exporting a model from MySQL workbench. Been looking around for a bit but can't find any answers that could help in this specific case.
Trying to export a script created in MySQL workbench to phpMyAdmin. Can anyone see what is wrong with this part of the script?

..it goes on but thats not where the errors coming up
..And I am trying to do this through a Delphi ADOQuery (though I dont think that's where the error is)
I believe the 'use' statement is only used in the mysql command line client to switch to another database. If you want to "use" another database, you'll probably need to use some API call or just reconnect directly to the newly created database.
