I want to insert a certain value into a certain field of five different rows altogether. But whenever I run this query it doesn't get executed. What's wrong with it, and how can I fix it?
INSERT INTO `employee`(`password`) VALUES ('abc') WHERE `id` IN (1,2,3,4,5);
An INSERT can't have a WHERE clause. It looks like you meant to do an update:
UPDATE `employee`
SET `password` = 'abc'
WHERE `id` IN (1,2,3,4,5);
Or perhaps a multi-row insert:
INSERT INTO `employee` (`id`, `password`)
VALUES (1, 'abc'), (2, 'abc'), (3, 'abc'), (4, 'abc'), (5, 'abc');
Also, FYI, you really shouldn't be storing passwords as plain text, which it looks like you may be doing.

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've seen this error mentioned on StackOverflow, but not in the context I am using. I am relatively new to Teradata and this behavior is throwing me for a loop. Here is code that works:
INSERT INTO test_table (this, that) VALUES (1, 2);
Here is code that throws the error:
INSERT INTO test_table (this, that) VALUES (1, 2), (3, 4);
This is super confusing to me because the Teradata docs have the following example:
INSERT INTO cities VALUES (2, 'San Jose'), (3, 'Oakland');
Could someone show me what am I missing here? Thanks!
Teradata only allows you to insert one record with a single values. You can see this in the syntax diagram for insert -- there is no "backloop".
Two inserts is a simple workaround:
INSERT INTO test_table (this, that)
VALUES (1, 2);
INSERT INTO test_table (this, that)
VALUES (3, 4);
I have a very long list of data that i need to insert into a table. I have a pre-formatted list of queries that does it, in which i go through each query and replace 'X' with part of an item number. Is there any way that i can save myself typing or copying the text dozens of times over by just replacing 'X' with the text I need?
My set of queries is much longer than this but looks like
Insert into Inventory_Ingredients
Values ('X300', 1001, '30label', 1, '0', 0)
Insert into Inventory_Ingredients
Values ('X300', 1001, '30b', 1, '0', 0)
Insert into Inventory_Ingredients
Values ('X300', 1001, 'Shrink30', 1, '0', .50/100)
Insert into Inventory_Ingredients
Values ('X300', 1001, 'recipeX', 1, '0', 1.00/100)
Insert into Inventory_Ingredients
Values ('X300', 1001, 'wiznic100', 0*30/100, '0', 2.00/100)
Insert into Inventory_Ingredients
Values ('X300', 1001, 'vg', 30-(select sum(inventory_ingredients.quantity)
from inventory_ingredients
where itemnum='recipeX'
group by itemnum)-(0*30/100), '0', 2.00/100)
Any reason dynamic SQL wouldn't work for what you're doing? Very useful in situations like this. Or if the X is just for values being inserted rather than for changing the query structure, variables would likely do the trick. Even so, I bet one of the two options will do it for you. Here's a good site for dynamic SQL help... https://www.mssqltips.com/sqlservertip/1160/execute-dynamic-sql-commands-in-sql-server/
I have a SQL script like this which I run from the command line using psql:
insert into "A"."B" values
(1, 'name=a', 'a#example.com', 'K')
How do I convert it into INSERT command inside a database?
INSERT INTO "A"."B" (first_column, second_c, third_c, fourth_1)
VALUES ('2', 'name=a', 'a#example.com.com', 'K');
Also what does "A"."B" do? I read somewhere that double quotes are needed when table name has Capitals. I seem to get an error with that when I run commands inside the database.
You said that your database name was DB and your table name was B.
You can simply use the table name alone:
INSERT INTO "B" (first_column, second_c, third_c, fourth_1)
VALUES ('2', 'name=a', 'a#example.com.com', 'K');
If you want to include the database name, then use:
INSERT INTO "DB"."B" (first_column, second_c, third_c, fourth_1)
VALUES ('2', 'name=a', 'a#example.com.com', 'K');
The double quotes are only required when the name of any entity (e.g. table, column, etc...) is a reserved word.
You can use this query where A is schema and B is table name.
INSERT INTO "A"."B" (first_column, second_c, third_c, fourth_1)
VALUES ('2', 'name=a', 'a#example.com.com', 'K');
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)
