I just can't see what needs to be changed in this code:
create table tblGirlScout (
GirlScout_ID varchar(10,0) not null,
GirlScoutFirstName varchar(25) not null,
GirlScoutLastName varchar(25),
GirlScoutAddress varchar(30),
GirlScoutCity varchar(20),
GirlScoutState char(2),
GirlScoutPostalCode varchar(9),
Constraint tblGirlScout_PK Primary Key(GirlScout_ID)
);
I believe you wanted to set GirlScout_ID column as a number, not a varchar. This is what causes the problem. Here is a fix
create table tblGirlScout (
GirlScout_ID number(10,0) not null,
GirlScoutFirstName varchar(25) not null,
GirlScoutLastName varchar(25),
GirlScoutAddress varchar(30),
GirlScoutCity varchar(20),
GirlScoutState char(2),
GirlScoutPostalCode varchar(9),
Constraint tblGirlScout_PK Primary Key(GirlScout_ID)
);

This is the code that created the table.
CREATE TABLE CUSTOMERS
(
Customer_ID INT NOT NULL,
CHECK(Customer_ID <= 11),
First_Name varchar(20) NOT NULL,
Last_Name varchar(30),
Home_Street varchar(30),
Home_City varchar(20),
Home_State varchar(2),
Home_Zip varchar(5),
PhoneNumber varchar(11) NOT NULL
);
ALTER TABLE CUSTOMERS
ADD CONSTRAINT PK_CUSTOMERS PRIMARY KEY(Customer_ID);
Then I try to insert data (using this code) into the table and that is where I get this error.
INSERT INTO dbo.CUSTOMERS(Customer_ID, First_Name, Last_Name, Home_Street, Home_City, Home_State, Home_Zip, PhoneNumber)
VALUES (11223344556, 'John', 'Doe', '1234 Hand Street', 'Wahiawa', 'HI', 96786, 2535551267);
What am I doing wrong and what can I do to fix this issue?
AS per my understanding you are checking length of Customer_ID <=11 so you should mention len(Customer_ID)<=11 it will work and you should alter datatype of Customer_ID int to bigint
CREATE TABLE CUSTOMERS
(
Customer_ID bigINT NOT NULL,
CHECK(len(Customer_ID)<=11),
First_Name varchar(20) NOT NULL,
Last_Name varchar(30),
Home_Street varchar(30),
Home_City varchar(20),
Home_State varchar(2),
Home_Zip varchar(5),
PhoneNumber varchar(11) NOT NULL
);
ALTER TABLE CUSTOMERS
ADD CONSTRAINT PK_CUSTOMERS
PRIMARY KEY(Customer_ID);
INSERT INTO dbo.CUSTOMERS(Customer_ID,First_Name,Last_Name,Home_Street,
Home_City,Home_State,Home_Zip,PhoneNumber)
VALUES(11223344556,'John','Doe','1234 Hand Street',
'Wahiawa','HI',96786,2535551267);
You need customer id to be bigint:
CREATE TABLE CUSTOMERS
(
Customer_ID BIGINT NOT NULL,
CHECK(Customer_ID<=11),
First_Name varchar(20) NOT NULL,
Last_Name varchar(30),
Home_Street varchar(30),
Home_City varchar(20),
Home_State varchar(2),
Home_Zip varchar(5),
PhoneNumber varchar(11) NOT NULL
);
ALTER TABLE CUSTOMERS
ADD CONSTRAINT PK_CUSTOMERS
PRIMARY KEY(Customer_ID);
The problem may be due to CHECK(Customer_ID<=11) since Customer_ID id integer datatype the server may check for integer validation and not length validation. Try to change the validation.
This may be a stupid mistake but I'm new to Informix and I can't seem to figure out why none of my CREATE TABLE statements won't run. I keep getting a syntax error on all of my CREATE TABLE statements.

);
create table state(
state_code CHAR(2) NOT NULL,

CONSTRAINT state_pk PRIMARY KEY(state_code)
);
Any help will be appreciated.
For reasons I don't understand, Informix requires the constraint name after the constraint, whereas standard SQL requires the constraint name before the constraint.
Thus, in addition to changing zip-code to zip_code (as pointed out by daniel.shih in an answer), you need:
CREATE TABLE customer(
store_num INTEGER NOT NULL,
store_name VARCHAR(20) NOT NULL,
addr VARCHAR(20),
addr2 VARCHAR(20),
city VARCHAR(15),
state VARCHAR(2),
zip_code VARCHAR(5),
contact_name VARCHAR(30),
phone VARCHAR(18),
PRIMARY KEY(store_num) CONSTRAINT cust_pk
);
You can try customer's field zip_code instead of zip-code
bit confusing question here:
I am trying to create a composite FK from a composite PK. I'll show you my tables in question that I'm having problems with;
CREATE TABLE Weapons (
Weapon_ID VARCHAR(10) NOT NULL,
Weapon_Name VARCHAR(30),
Range_In_Meters INT,
Maximum_Number_Of_Uses INT,
Damage_Factor INT,
Cost INT,
primary key(Weapon_ID));
CREATE TABLE WeaponInventory (
Inventory_ID VARCHAR(30) NOT NULL,
WeaponInventory_ID Varchar(10) NOT NULL,
Weapon_ID VARCHAR(10) REFERENCES Weapons(Weapon_ID) NOT NULL,
primary key(Inventory_ID, WeaponInventory_ID));
CREATE TABLE Avatars (

Weapon_ID VARCHAR(10) NOT NULL,
Player_ID VARCHAR(10) NOT NULL,
PRIMARY KEY (Avatar_ID),
FOREIGN KEY (Inventory_ID, Weapon_ID)
REFERENCES WeaponInventory (Inventory_ID, Weapon_ID));
In the table Avatars, I have been trying to create this Foreign key but I'm having no luck. I have errors such as:
ORA-02270: no matching unique or primary key for this column-list
and:
ORA-02270: no matching unique or primary key for this column-list
Any help would be greatly appreciated! I just keep getting confused and ending up in the same place! (:
I think you planned to reference column WeaponInventory_ID (instead of Weapon_ID) in table WeaponInventory:
FOREIGN KEY (Inventory_ID, Weapon_ID)
REFERENCES WeaponInventory (Inventory_ID, WeaponInventory_ID) -- see here
Note that Weapon_ID is not part of the PK in WeaponInventory:
CREATE TABLE WeaponInventory (
Inventory_ID VARCHAR(30) NOT NULL,
WeaponInventory_ID Varchar(10) NOT NULL,
Weapon_ID VARCHAR(10) REFERENCES Weapons(Weapon_ID) NOT NULL,
primary key(Inventory_ID, WeaponInventory_ID) -- Weapon_ID is not part of PK
);

I have designed a database for online donation. I have not added foreign key relationships because first I want to achieve a simple design. It's currently 11 tables, and it seems already more complicated than necessary.
The first one is registration table. The other 8 are different item types which will be donated by donors or by receivers, and 1 will be for post table it means when the user or receiver wants donate they will post what they want to donate or what they want ask others to give them. The last one will be for comment, the comment might be on the post by donors or receivers.
Can any one can help me re-design this in a simpler way?

I have this sql
CREATE TABLE PATIENTS

);
I have no idea why I keep getting this error. I have search a lot but still nothing that can solve it. Any ideas?
Thanks
You have to specify column from HEALTH_INSURANCES table in FOREIGN KEY caluse.
You should also remove ON UPDATE CASCADE. You can use a trigger on update instead of this clause.
CREATE TABLE PATIENTS
(
patientID NUMBER NOT NULL,
healthInsID NUMBER,
fname VARCHAR(20) NOT NULL,
minit VARCHAR(15),
lname VARCHAR(30) NOT NULL,
gender CHAR(2),
email VARCHAR(40),
street VARCHAR(40),
postalCode NUMBER,

country VARCHAR(20),
PRIMARY KEY (patientID),
FOREIGN KEY (healthInsID) REFERENCES HEALTH_INSURANCES (healthInsID)
ON DELETE SET NULL
);
