I have the following SQL code to create a table.
-- Table: Yelp_User
-- ADDED TO JAVA FILE
CREATE TABLE Yelp_User (
Yelp_Id char(22) NOT NULL,
Yelping_since date NOT NULL,
Name varchar2(50) NOT NULL,
Average_Stars number(51,50) NOT NULL,
CONSTRAINT Yelp_User_pk PRIMARY KEY (Yelp_Id)
) ;
However, I get the following error, which I suspect is coming from the average_stars attribute.
ORA-01727: numeric precision specifier is out of range (1 to 38)
Examples of average_stars values are as follows (from a JSON file I will be parsing):
3.8300000000000001
3.9700000000000002
4.4000000000000004
3.7799999999999998

I am trying to create a table in SQL and every time it I get the following error message:
ORA-00902: invalid datatype
SQL> create table BUSINESS (
2 B_IDINTEGER PRIMARY KEY,
3 B_CITYchar(20) not null,
4 B_NAMECHAR (20) NOT NULL,
5 B_CATEGORY(S) CHAR (25),
6 B_ACCTCHAR (25)
7 );
B_CITYchar(20) not null,
*
ERROR at line 3:
ORA-00902: invalid datatype
It is supposed to say table created but I don't know what is wrong with line 3.
You have several errors in your code. Try something like this:
create table BUSINESS (
B_ID INTEGER PRIMARY KEY,
B_CITY varchar2(20) not null,
B_NAME varchar2(20) NOT NULL,
B_CATEGORY varchar2(25),
B_ACCT varchar2(25)
);
Note that you should generally use variable length strings unless you know the value has a fixed length (which might be true of b_acct but is not true for b_city).
I am experimenting with PostgreSQL coming from SQL using MySQL and I simply wish to create a table with this piece of code which is valid SQL:
CREATE TABLE flat_10
(
pk_flat_id INT(30) DEFAULT 1,
rooms INT(10) UNSIGNED NOT NULL,
room_label CHAR(1) NOT NULL,
PRIMARY KEY (flat_id)
);
I get the error
ERROR: syntax error at or near "("
LINE 3: pk_flat_id integer(30) DEFAULT 1,
I have conducted searches on the web and found no answer and I cant seem to find an answer in the PostgreSQL manual. What am I doing wrong?
I explicitly want to set a limit to the number of digits that can be inserted into the "pk_flat_id" field

Your current table definition does not impose a "size limit" in any way. In MySQL the parameter for the intdata type is only a hint for applications on the display width of the column when displaying it.
You can store the value 2147483647 in an int(1) without any problems.
If you want to limit the values to be stored in an integer column you can use a check constraint:
CREATE TABLE flat_10
(
pk_flat_id bigint DEFAULT 1,
rooms integer NOT NULL,
room_label CHAR(1) NOT NULL,
PRIMARY KEY (flat_id),
constraint valid_number
check (pk_flat_id <= 999999999)
);
The answer is that you use numeric or decimal types. These are documented here.
Note that these types can take an optional precision argument, but you don't want that. So:
CREATE TABLE flat_10
(
pk_flat_id DECIMAL(30) DEFAULT 1,
rooms DECIMAL(10) NOT NULL,
room_label CHAR(1) NOT NULL,
PRIMARY KEY (pk_flat_id)
);
Here is a SQL Fiddle.
I don't think that Postgres supports unsigned decimals. And, it seems like you really want serial types for your keys and the long number of digits is superfluous.
Changing integer to numeric works.
CREATE TABLE flat_10
(
pk_flat_id bigint DEFAULT 1,
rooms numeric NOT NULL,
room_label CHAR(1) NOT NULL,
);
I am new to MSSQL 2014 Server, my professor listed these steps to make a table, I don't know the proper steps to create tables in the pictures listed below, please help.
Create and populate (insert values) the following tables per table description and data values provided
DEPARTMENT
EMPLOYEE
PROJECT
ASSIGNMENT
Add a SQL Comment to include /* * Your First Name_Your Last Name* */ when inserting corresponding values for each table.
What I tried so far:
CREATE TABLE DEPARTMENT(
DepartmentName Text(35) PRIMARY KEY,
BudgetCode Text(30) NOT NULL,
OfficeNumber Text(15) NOT NULL,
Phone Text(12) NOT NULL, );
I have put this to my query and the error is
Msg 2716, Level 16, State 1, Line 1 Column, parameter, or variable #1: Cannot specify a column width on data type text.
Try this(I assume that your table exists in dbo schema):
IF OBJECT_ID(N'dbo.DEPARTMENT', N'U') IS NOT NULL
BEGIN
DROP TABLE DEPARTMENT
END
GO
CREATE TABLE DEPARTMENT(
DepartmentName varchar(35) PRIMARY KEY,
BudgetCode varchar(30) NOT NULL,
OfficeNumber varchar(15) NOT NULL,
Phone varchar(12) NOT NULL
);
You can not define width for Text data type. In case which you need to define width you can use char or varchar data types. Also keep in mind that if you need to work with Unicode characters then you will need to use nchar or nvarchar instead.

I keep trying to create a basic table. Every time I try to create the table I get the error
literal does not match format string
I'm trying to limit the years of the tournament between 2005 and 2100. The error is between DATE '2005'.
This is my code:
Create table Tournament_T
(Tournament_name VARCHAR (50) PRIMARY KEY NOT NULL,
Tournament_year INTEGER NOT NULL,
CONSTRAINT RANGE CHECK (Tournament_year BETWEEN DATE '2005' AND '2100'),
Tournament_rules CLOB NOT NULL,
Tournament_fee VARCHAR(1000) NOT NULL,
Tournment_eligibility VARCHAR (1000) NOT NULL );
COMMIT;
Your constraint is using the date keyword, but you don't need it. Just do:
CONSTRAINT RANGE CHECK (Tournament_year BETWEEN 2005 AND 2100),
Your column is an integer, not a date.
