I use Postgres and I've integration app which write data to database. My column should not be null but my app send null value. I tried to set default value but query override this rule with null value. How can i handle this change without code.
My Column configuration looks like this.
If you won't or can't change the query in code, you have to use trigger
If you can change code structure and query:
If the column has a default value, then no need to send NULL value to query
-- Before change
insert into your_table (id, name, default_col) values
(1, 'name', null);
-- After change (remove null data)
insert into your_table (id, name) values
(1, 'name');
Or send default value in insert query
-- Before change
insert into your_table (id, name, default_col) values
(1, 'name', null);
-- After change (Use default keyboard)
insert into your_table (id, name, default_col) values
(1, 'name', default);
I want to insert rows into a SQLite3 table using the knex.raw method. Unfortunately I get a 'SQLITE_RANGE' error, which makes my test fail.
I have verified the bindings passed to the raw query in the following fashion:
They respect the order of the INSERT statement
They respect the specified column types
They respect the number of bindings requested in the raw query
Beyond that I have looked online, but couldn't find a solution to my issue. Below are the details of the operation attempted:
Engine: sqlite3 ^3.1.13
SQL Client: knex ^0.14.4
Environment: electron ^1.7.11
Error:
SQLITE_RANGE: bind or column index out of range errno: 25, code: 'SQLITE_RANGE'
Table definition:
-- --------------------------------------------------------
--
-- Table structure for table `ds13odba`
--
CREATE TABLE IF NOT EXISTS `ds13odba` (
`SURGERY_CODE` VARCHAR(6) ,
`TYPE` VARCHAR(1) ,
`FP59STALIB` VARCHAR(6) ,
`ID` INT UNSIGNED NOT NULL ,
`createdAt` DATETIME DEFAULT CURRENT_TIMESTAMP NOT NULL,
`updatedAt` DATETIME DEFAULT CURRENT_TIMESTAMP NOT NULL
);
-- --------------------------------------------------------
*Take note that the column types defined here are affinity types, i.e. MySQL types. These are valid in SQLite3 and are casted and optimized by the engine to their equivalent in SQLite3.
Query:
INSERT INTO `ds13odba` (FP59STALIB, ID, SURGERY_CODE, TYPE) VALUES (?,?,?,?);
INSERT INTO `ds13odba` (FP59STALIB, ID, SURGERY_CODE, TYPE) VALUES (?,?,?,?);
INSERT INTO `ds13odba` (FP59STALIB, ID, SURGERY_CODE, TYPE) VALUES (?,?,?,?);
Bindings:
[
'047202', 1, '000001', 'D',
'047203', 2, '000002', 'D',
'047204', 3, '000003', 'D'
]
Calling code:
await knex.raw(...convertToInsertSQL(records));
Which resolves to:
await knex.raw(insertStatements.join('\n'), bindings);
Could you help me with this issue?

The issue stems from SQLite3's lack of support of multi-statements per exec() call, as documented here.
After some testing on my end, I discovered that the SQLite3 engine will assign automatically all the bindings to the first statement of the prepared SQL. Any following statements will be ignored.
This still applies for transactions, as the bindings will be applied to the 'BEGIN TRANSACTION;' statement rather than to the following statements.
The solution is to use a compound INSERT statement with bindings.
Hence this:
INSERT INTO `ds13odba` (FP59STALIB, ID, SURGERY_CODE, TYPE) VALUES (?,?,?,?);
INSERT INTO `ds13odba` (FP59STALIB, ID, SURGERY_CODE, TYPE) VALUES (?,?,?,?);
INSERT INTO `ds13odba` (FP59STALIB, ID, SURGERY_CODE, TYPE) VALUES (?,?,?,?);
becomes this:
INSERT INTO `ds13odba` (FP59STALIB, ID, SURGERY_CODE, TYPE)
VALUES (?,?,?,?), (?,?,?,?), (?,?,?,?);
*Bear in mind that compound INSERT statements are only available as of version 3.7.11 of the SQLite3 engine.
I don't see anything obviously wrong with the info you've posted, but you haven't posted the actual .raw() statements, which would help with debugging.
So attempting to assist, I would suggest that you add an .on('query-error'... clause like that below, which will log the SQL that is failing. Many times this will make the problem obvious.
knex.raw(...your-stuff...)
.on('query-error', function(ex, obj) {
console.log("KNEX-query-error ex:", ex, "obj:", obj);
})
Good luck!
I get an error when trying to run this SQL query in MS Access:
INSERT INTO Learner (learnerPersonIDPKFK, registrationDate)
VALUES (1, 21/09/2015);
INSERT INTO Learner (learnerPersonIDPKFK, registrationDate, recommendedByLearnerPersonIDFK)
VALUES (2, 05/03/2016, 1);
This is the error:
enter image description here
The Learner table looks like this:
CREATE TABLE Learner
(
learnerPersonIDPKFK INT NOT NULL PRIMARY KEY,
registrationDate DATETIME,
recommendedByLearnerPersonIDFK INT NOT NULL,
CONSTRAINT fk_recommendedByLearnerPersonIDFK
FOREIGN KEY(recommendedByLearnerPersonIDFK)
REFERENCES Learner (learnerPersonIDPKFK)
);
Try wrapping your dates in single quotes:
INSERT INTO Learner (learnerPersonIDPKFK, registrationDate)
VALUES (1, '21/09/2015');
INSERT INTO Learner (learnerPersonIDPKFK, registrationDate, recommendedByLearnerPersonIDFK)
VALUES (2, '05/03/2016', 1);
Depending on your localization settings for the DATETIME format, you may need to use the MM/DD/YYYY format. Remember, your passing in a varchar and letting SQL try to "guess" how to implicitly convert it:
INSERT INTO Learner (learnerPersonIDPKFK, registrationDate)
VALUES (1, '09/21/2015');
INSERT INTO Learner (learnerPersonIDPKFK, registrationDate, recommendedByLearnerPersonIDFK)
VALUES (2, '03/05/2016', 1);
Use a simple tester to verify if SQL can "guess" your date formating:
SELECT CAST('09/21/2015' AS DATETIME)
I wish to insert into an SQL table in a field whose data type is text. However I am informed of an error saying ' check datatype' my Name field is of type nvarchar and my job field is of type text.
INSERT INTO Table1 (Name, Job) VALUES ('John', 'Clerk')
In MS SQL Server, you wont be able to insert string values(with more than 1 characters) in table if the column of type nvarchar. You can only insert only one character using nvarchar.
If you wish to insert some text, please specify the some size with nvarchar.
For example in your case:
Create table Table1(Name nvarchar(5), Job Text)
Insert into Table1(Name, Job) values ('John','Clerk')
This will work.
Hope it will help you out.
I tried to insert some rows into SQL server database and throws an error:
Conversion failed when converting the varchar value 'null' to data type bit
Could anyone explain what is this for?
This is not in a program.
What you might be trying
INSERT INTO TESTTABLE(BITCOLUMN) VALUES('NULL')
What should it actually be..
INSERT INTO TESTTABLE(BITCOLUMN) VALUES(NULL)
If you want to insert a null value into a column, you need to write NULL, and not 'NULL' (wrapping it in quotes indicates that it is a VARCHAR containing the letters N, U, L L - not a null value).
That is what the error message is telling you: you're trying to insert the VARCHAR value 'NULL' into a column that will only accept bit data.
Change the 'NULL' in your insert query to NULL.
You need something like this:
INSERT INTO TableName(ColumnName) VALUES(NULL); --this is the right way
Instead of this:
INSERT INTO TableName(ColumnName) VALUES('NULL'); --this is the wrong way
