This code does not run:
alter table States
add Key varchar(400) character set utf8 not null
The error:
Error in query (1064): Syntax error near 'varchar(400) character set utf8 not null' at line 2
What is wrong in this code?
Key is a reserved keyword in MySql (hence in MariaDB too), so to use it as an identifier you must enclose it in backticks. This will do:
alter table `States` add `Key` varchar(400) character set utf8 not null
I've also enclosed States in backticks, just for the sake of consistency, even though it's not really required.
An option would be to use another name for the new column, so to avoid the same problem in queries involving it afterwards.
I'm new at SQLite and i'm trying to add a column into a table which is exist or not exist with the statement below.
ALTER TABLE
table1
ADD
columnx TEXT NULL
WHERE
type = "table"
i've got the SQLiteException: near "WHERE": syntax error (code 1) error. What is wrong with that statement? What is the correct way of adding new column into a table with checking the existance of the table?
I am a completely new to SQL and I am follow a tutorial verbatim to try and create a new table in my first database. However I am getting the following error.
USE menu;
CREATE TABLE Burgers
(
`Burger Number` TINYINT,
Burger VARCHAR(50),
Price DECIMAL(5,2),
Description VARCHAR(300),
);
Yields SQL Error 1064:
SQL Error (1064): You have an errror in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ')' at line 8
I made sure to use commas to separate each column and used parenthesis to what I understand is the proper way to do so. I am not sure if version is relevant but I am using version 10.5.8 of MariaDB. Any insight is appreciated!
You have one comma too many.
...
Description VARCHAR(300),
);
You need commas between each column, index, or constraint within the CREATE TABLE statement, except for the last one before the closing parenthesis.
It should be like this:
...
Description VARCHAR(300)
);
General tip about syntax errors: They tell you exactly where to look for the problem, because it reports the place in your SQL statement where the syntax parser got confused.
In this case it reported:
...right syntax to use near ')' at line 8
This tells you the problem is at that point in the syntax. The ) didn't belong there, because the syntax was expecting something else. Because commas separate columns, it was expecting another column definition following a comma.
We use pervasive Database with Zen Contol-Center And want to perform the following SQl-Statenemt:
insert into MWlog
(Signatur,Datum,Uhrzeit,Auftrag,Probe,Parameter,Matrix,`Messwert neu`,Zugriff,`Messwert alt`,Aenderungsgrund)
values
('ML','2020-12-01','15:04:50','230176','230176','Bas. wirk.','TM','5.62','5','5.62','Neuer Import')
We get the following error-message:

What is wrong in the SQL Statement?
(We found out that the problem are the spaces in the field-Names)
We are using
Zen Control Center
Zen Install Version 14.10.035.
Java Version 1.8.0_222.
Gord Thompson is correct. You need to use double quotes around field names with spaces or field names that are reserved key words. You statements should be:
insert into MWlog
(Signatur,Datum,Uhrzeit,Auftrag,Probe,Parameter,Matrix,"Messwert neu",Zugriff,"Messwert alt",Aenderungsgrund)
values
('ML','2020-12-01','15:04:50','230176','230176','Bas. wirk.','TM','5.62','5','5.62','Neuer Import')
I'm currently trying to connect my R session to a MySQL server using the RMySQL package.
One of the tables on the server is called "order", I already searched how you can import a table called order with MySQL (by putting it into ''), yet the syntax does not work for the RMySQL query.
when I run the following statement:
order_query = dbSendQuery(mydb,"SELECT * FROM 'order'")
It returns the following error:
Error in .local(conn, statement, ...) : could not run statement:
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 ''order'' at line 1
Anyone knows how to get around this in R?
Single quotes in MySQL indicate string literals, and you should not be putting them around your table names. Try the query without the quotes:
order_query = dbSendQuery(mydb,"SELECT * FROM `order`")
If you did, for some reason, need to escape your table name, then use backticks, e.g.
SELECT * FROM `some table` -- table name with a space (generally a bad thing)
Edit:
As #Ralf pointed out, in this case you do need backticks because ORDER is a MySQL keyword and you should not be using it to name your tables and columns.
