I am trying to create a table in Oracle SQL Developer but I am getting error ORA-00902.
Here is my schema for the table creation
CREATE TABLE APPOINTMENT(
Appointment NUMBER(8) NOT NULL,
PatientID NUMBER(8) NOT NULL,
DateOfVisit DATE NOT NULL,
PhysioName VARCHAR2(50) NOT NULL,
MassageOffered BOOLEAN NOT NULL, <-- the line giving the error -->
CONSTRAINT APPOINTMENT_PK PRIMARY KEY (Appointment)
);
What am I doing wrong?
Thanks in advance
Last I heard there were no boolean type in oracle. Use number(1) instead!
Oracle does not support the boolean data type at schema level, though it is supported in PL/SQL blocks. By schema level, I mean you cannot create table columns with type as boolean, nor nested table types of records with one of the columns as boolean. You have that freedom in PL/SQL though, where you can create a record type collection with a boolean column.
As a workaround I would suggest use CHAR(1 byte) type, as it will take just one byte to store your value, as opposed to two bytes for NUMBER format. Read more about data types and sizes here on Oracle Docs.
Oracle doesn't support boolean for table column datatype. You should probably use a CHAR(1) (Y/N)

i think u got a below good result
http://docs.oracle.com/cd/E11882_01/appdev.112/e25519/datatypes.htm#CJACJGBG
When using an Entity class to create the schema, defining the boolean value as below will help
#Column(columnDefinition = "number default 0")
private boolean picked;

I'm trying to create a table containing opening hours (for cafeteria's)
However I am having some issues with implementing the constraint. For each resto, the openinghours cannot overlap.
CREATE table openinghours(
id serial PRIMARY key,
start timestamp NOT NULL,
duration interval NOT NULL,
resto_naam varchar REFERENCES resto(naam),
constraint openingstijden_duplicate_check EXCLUDE USING GIST (
resto_naam WITH =,
/* Check wether there is no overlap between the dates */
tsrange(start, start + duration) WITH &&
)
);
when I try to execute this SQL I get the following error:
ERROR: data type character varying has no default operator class for access method "gist"
HINT: You must specify an operator class for the index or define a default operator class for the data type.
SQL state: 42704
Any help would be appreciated!
You need the btree_gist extension for this to work. Execute create btree_gist and try again.
Best regards,
Bjarni
Situation
My data is stored on a PostgreSQL server on my network. I've linked an ODBC data source to create linked tables to my data. The table in concern is one that is designed to track classes and their session details - including attendance. The table's design is so:
CREATE TABLE ClassSession
(
id integer NOT NULL DEFAULT nextval('"seq_ClassSession_id"'::regclass),
teacher_id integer NOT NULL,
class_name character varying(50) NOT NULL,
clients_in_attendance integer[],
date_of_session date DEFAULT CURRENT_DATE,
CONSTRAINT "ClassSession_pkey" PRIMARY KEY (id)
)
Problem
MS Access interprets integer[] data types as Short Text (pictured below). This isn't really a big deal as long as I can match the correct format of integer enclosed in { and } - with each being separated by a ,. An example would be: {12,34,56,67,78}.
Integer arrays as Short Text in Access - design view
Query example of Access interpreting integer arrays as short text/format
Question
I was looking for some direction on how to design a form in Access that can insert data into this table while restricted to this format (using the {, }, and , in plaintext) without having the user type the brackets, each number, and comma to separate the client_id values. Is anyone able to help?
I have a table with a column nif which has to be exactly 9 digits long, after I tried to do:
CREATE TABLE fornecedor(
nif numeric(9) PRIMARY KEY,
nome varchar(64) NOT NULL,
CONSTRAINT nif_tamanho CHECK (length(to_char(nif, 'FM999MI')) = 9));
INSERT INTO fornecedor(nif, nome) VALUES (123456789, 'Pmsmm');
It returns an error saying:
ERROR: new row for relation "fornecedor" violates check constraint "nif_tamanho"
How do I make it so that the inserted number is verified having 9 digits exactly ?
Thanks in advance
As you mention in your comment, you need a string data type if you don't want to lose leading zeroes.
But I think that the correct solution depends on how you want to use the column. It is always good to choose the data type according to the column's semantics.
If you need to do arithmetic or numeric comparisons with the data, choose integer by all means (you can add a check constraint on nif < 100000000). You can always format the value with leading zeroes when you convert it to a string for output.
If you need to do string operations on the value (e.g. substrings), storing the data as a sting type is preferable.
I am trying to create a SQL table in Netbeans 8.0 with one of its columns meant to store a byte[] (so VARBINARY is the type I am looking for). The wizard for the creation of a new table offers me the option of VARCHAR FOR BIT DATA, which should work, but it raises a syntax error when creating the table:
create table "BANK".Accounts
(
id NUMERIC not null,
pin VARCHAR FOR BIT DATA not null,
primary key(id)
)
The error is due to the presence of the word FOR, so I manually change the statement so that it is
create table "BANK".Accounts
(
id NUMERIC not null,
pin "VARCHAR FOR BIT DATA" not null,
primary key(id)
)
but now the problem is that the type does not exist. Any ideas?
Thank you.
Here's the manual page for VARCHAR FOR BIT DATA: http://db.apache.org/derby/docs/10.10/ref/rrefsqlj32714.html
Note the section that says:
Unlike the case for the CHAR FOR BIT DATA type, there is no default length for a VARCHAR FOR BIT DATA type. The maximum size of the length value is 32,672 bytes.
So the problem is that you haven't specified a length.
If your byte array is, say, 256 bytes long, you could specify
pin VARCHAR (256) FOR BIT DATA NOT NULL,
You might also consider using BLOB if that fits your requirements. You can see all the Derby data types here: http://db.apache.org/derby/docs/10.10/ref/crefsqlj31068.html
I am new to writing SQL and using Oracle... so I'm sorry if this is obvious but I can't figure it out. It's telling me that I'm missing a right parenthesis but as far as I can tell they are all there. It seems to be a problem with the VARBINARY line but I don't know why.
CREATE TABLE DATA_VALUE
(
DATA_ID VARCHAR2(40) NOT NULL,
POSITION INT NOT NULL,
VALUE VARCHAR2(50),
BINARY_VALUE VARBINARY(50),
DATA_TYPE VARCHAR2(20),
CONSTRAINT DATA_VALUE_PK PRIMARY KEY(DATA_ID, POSITION)
);
VARBINARY is not an Oracle data type. A quick search suggests MySQL and SQL Server have it, at least, but not Oracle. Perhaps you need to explain what you want to store in that field. The closest I can think you might mean is RAW.
The valid built-in datatypes are listed in the documentation:
The RAW and LONG RAW data types store data that is not to be
explicitly converted by Oracle Database when moving data between
different systems. These data types are intended for binary data or
byte strings.
This Microsoft article suggests you should be using RAW as a replacement for VARBINARY too, at least for the size you're talking about.
CREATE TABLE DATA_VALUE
(
DATA_ID VARCHAR2(40) NOT NULL,
POSITION INT NOT NULL,
VALUE VARCHAR2(50),
BINARY_VALUE RAW(50),
DATA_TYPE VARCHAR2(20),
CONSTRAINT DATA_VALUE_PK PRIMARY KEY(DATA_ID, POSITION)
);
table DATA_VALUE created.
