I have a CSV file which consists of one column. I want to insert (not import) all the elements in the columns into the database table. I know that if I wanted to insert few elements, then I can use the below statement to insert individually.
INSERT INTO table(column_name )
VALUES (element1);
But is there a method that I can insert all the elements at once?
You can just comma separate the values like below. I sometimes use Excel to do the formatting if you have a lot of values.
INSERT INTO table
(column_name)
VALUES
(element1), (element2)
I have a local db that I'm trying to insert multiple rows of data, but I do not want duplicates. I do not have a second db that I'm trying to insert from. I have an sql file. The structure is this for the db I'm inserting into:
(db)artists
(table)names-> ID | ArtistName | ArtistURL | Modified
I am trying to do this insertion:
INSERT names (ArtistName, Modified)
VALUES (name1, date),
(name2, date2),
...
(name40, date40)
The question is, how can I insert data and avoid duplication by checking a specific column to this list of data that I want inserted using SQL?
Duplicate what? Duplicate name? Duplicate row? I'll assume no dup ArtistName.
Have UNIQUE(ArtistName) (or PRIMARY KEY) on the table.
Use INSERT IGNORE instead of IGNORE.
(No LEFT JOIN, etc)
I ended up following the advice of #Hart CO a little bit by inserting all my values into a completely new table. Then I used this SQL statement:
SELECT ArtistName
FROM testing_table
WHERE !EXISTS
(SELECT ArtistName FROM names WHERE
testing_table.ArtistName = testing_table.ArtistName)
This gave me all my artist names that were in my data and not in the name table.
I then exported to an sql file and adjusted the INSERT a little bit to insert into the names table with the corresponding data.
INSERT IGNORE INTO `names` (ArtistName) VALUES
*all my values from the exported data*
Where (ArtistName) could have any of the data returned. For example,
(ArtistName, ArtistUrl, Modified). As long as the values returned from the export has 3 values.
This is probably not the most efficient, but it worked for what I was trying to do.
I want to copy the content of one column in table A and replace the contents (not insert into it - the number of rows will be the same) of another column in another table.
I can't a where condition, the table has only just been created at this point with one empty timestamp column. it will be populated via pyodbc class after the timestamps have been added - this query will fill the timestamps for me
What is the SQL command for this?
Thanks!
After discussion, this is the query needed : INSERT INTO OCAT_test_table (DateTimeStamp) SELECT DateTimeStamp FROM DunbarGen
I have a a table with the structure:
I also have a csv containing all the coupon codes only.
I want to use the same values for the other fields (except id of course).
What would be the be the sql required to insert these rows?
Using phpMyAdmin You can insert data from CSV only if it contains all of the required (NOT NULL column) values - the other (when missing) will be filled with defaults, NULL or auto_incremeneted. But Using this tool it is not possible to insert only codes from CSV and use some same values for the other fields. So here You have two options: either set the default values of that columns not being updated from CSV to the desired ones or create a PHP import script, that will do that for You (if You do not want to change the DB table schema).
I have INVOICE TABLE
I want to insert value by not specifying column names
using SQL Server, I have tried this but it is not working..please help
INSERT INTO INVOICE
VALUES( 1,1,KEYBOARD,1,15,5,75)
As long as you have the right number of columns in your INSERT statement, and as long as all the values except KEYBOARD are some numeric data type, and as long as you have suitable permissions, this should work.
INSERT INTO INVOICE VALUES( 1,1,'KEYBOARD',1,15,5,75);
SQL requires single quotes around text values.
But not using column names isn't a good practice. It's not unheard of for people to change the order of columns in a table. Changing the order of columns isn't a good practice, either, but some people insist on doing it anyway.
If somebody does that, and swaps the 5th and 7th columns in your table, your INSERT statement will still succeed--both those columns are numeric--but the INSERT will screw up your data.
Why would you want to do this? Not specifying column names is bad coding practice.
In your case, though, keyboard needs to be surrounded by single quotes:
INSERT INTO INVOICE VALUES( 1,1, 'KEYBOARD',1,15,5,75)
If you just don't want to type the column names, you can get them easily in SQL Server Management Studio. Open the "Object Browser", open the database, and choose "Tables". Choose the Invoice table. One of the options is "Columns".
Just click on the "Columns" name (no need to open it) and drag it into a query window. It will insert the list of columns.
yes you can directly insert values into table as follows:
insert into `schema`.`tablename` values(val1,val2,val3);
INSERT INTO INVOICE VALUES( 1,1,'KEYBOARD',1,15,5,75);
you forget to include the single quotes in keyboard,text required single quotes in sql
