Question

I’m trying to create an sql table called ‘cartable’. I’m currently using phpmyadmin via MAMP(Mac Version of WAMP).

When I click on the save button this error appears:

    SQL query:

CREATE TABLE `cardatabase`.`CARTABLE` (
`ID` VARCHAR( 10 ) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ,
`SLOTNUMBER` VARCHAR( 10 ) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ,
`STATUS` ENUM( 1 ) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ,
`LATITUDE` DECIMAL( 20 ) NOT NULL ,
`LONGITUDE` DECIMAL( 20 ) NOT NULL ,
`LOCATION` VARCHAR( 40 ) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ,
`DEVICEID` VARCHAR( 20 ) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL
) ENGINE = InnoDB CHARACTER SET utf8 COLLATE utf8_general_ci;

MySQL said: Documentation
#1064 - 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 '1) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `LATITUDE` DECIMAL(20) N' at line 1 

It seems to be a problem with the double data type as when I change it to varchar the table is created. Is there any other way around it? Thanks in advance, any help is much appreciated.

Your problem lies here:

`STATUS` ENUM( 1 ) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ,

An enum type is supposed to be a string object, not a numeric one.

From the MySQL doco,

An ENUM is a string object with a value chosen from a list of permitted values that are enumerated explicitly in the column specification at table creation time.

An enumeration value must be a quoted string literal; it may not be an expression, even one that evaluates to a string value.
