I have a table in SQL Server with some columns and a text file. I need to import data of two columns of text file into SQL table (two columns exist in SQL table for do it and no need two insert columns). How can I do it?
Use the SQL Server Importing Wizard and just ignore the columns in the mapping that are not required.
See link.
SQL Server Management Studio (SSMS) provides the Import Wizard task which you can use to copy data from one data source to another. You can choose from a variety of source and destination data source types, select tables to copy or specify your own query to extract data, and save your work as an SSIS package. In this section we will go through the Import Wizard and import data from an Excel spreadsheet into a table in a SQL Server database.

FOR CSV
// THIS IS THE DATA IN THE CSV FILE
Name,Class
Prabhat,4
Prabhat1,5
Prabhat2,6
// end OF CSV FILE
THE QUERY
CREATE TABLE CSVTest (Name varchar(100) , class varchar(10))
BULK
INSERT CSVTest
FROM 'C:\New folder (2)\testcsv.txt'
WITH
(
FIELDTERMINATOR = ',',
ROWTERMINATOR = '\n'
)
GO
--Check the content of the table.
SELECT *
FROM CSVTest
GO
--Drop the table to clean up database.
DROP TABLE CSVTest

I am brand new to Dbeaver and came from using Microsoft SQL Server. Right now I am just using it to connect to a csv file.
I want to create a temp table from the table I have in there that was brought in from a csv file. In SQL Server I would have done this:
select *
into #temptable
from mytable
What's the equivalent in Dbeaver?
I'm new to PostgreSQL and and looking for some guidance and best practice.
I have created a table by importing data from a csv file. I then altered the table by creating multiple generated columns like this:
ALTER TABLE master
ADD office VARCHAR(50)
GENERATED ALWAYS AS (CASE WHEN LEFT(location,4)='Chic' THEN 'CHI'
ELSE LEFT(location,strpos(location,'_')-1) END) STORED;
But when I try to import new data into the table I get the following error:
ERROR: column "office" is a generated column
DETAIL: Generated columns cannot be used in COPY.
My goal is to be able to import new data each day to the table and have the generated columns automatically populate in order to transform the data as I would like. How can I do so?
CREATE TEMP TABLE master (location VARCHAR);
ALTER TABLE master
ADD office VARCHAR
GENERATED ALWAYS AS (
CASE
WHEN LEFT(location, 4) = 'Chic' THEN 'CHI'
ELSE LEFT(location, strpos(location, '_') - 1)
END
) STORED;
--INSERT INTO master (location) VALUES ('Chicago');
--INSERT INTO master (location) VALUES ('New_York');
COPY master (location) FROM $$d:\cities.csv$$ CSV;
SELECT * FROM master;
Is this the structure and the behaviour you are expecting? If not, please provide more details regarding your table structure, your importable data and your importing commands.
Also, maybe when you try to import the csv file, the columns are not linked properly, or maybe the delimiter is not properly set. Try to specify each column in the exact order that appear in your csv file.
https://www.postgresql.org/docs/12/sql-copy.html
Note: d:\cities.csv contains:
Chicago
New_York
EDIT:
If columns positions are mixed up between table and csv, the following operation may come in handy:
1. create temporary table tmp (csv_column1 <data_type>, csv_column_2 <data_type>, ...); (including ALL csv columns)
2. copy tmp from '/path/to/file.csv';
3. insert into master (location, other_info, ...) select csv_column_3 as location, csv_column_7 as other_info, ... from tmp;
Importing data using an intermediate table may slow things down a little, but gives you a lot of flexibility.
I was getting the same error when importing to PG from a csv - I found that even though my column was generated, I still had to have it in the imported data, just left it empty. Worked fine when the column name was in there and mapped to my DB col name.
I have a list of data in excel list , how can i import them and insert into current created table. May i know the sql query for import excel data and insert into table ??Any help would be appreciated.
My excel list .CSV
table describe
new table with 0 record (13 columns same as excel list)
DB2 has the IMPORT and LOAD for getting external data into tables. In your case I would recommend IMPORT.
This would be the general statement:
import from yourfile of del insert into mytable
When you go to the documentation there are so-called "file type modifiers" that can be used to tell DB2 about the format of the data, the codepage, separators between the columns and more.
I want to bulk insert columns of a csv file to specific columns of a destination table.
Description - destination table has more columns than my csv file. So, I want the csv file columns to go to the right target columns using BULK INSERT.
Is this possible ? If yes, then how do I do it ?
I saw the tutorial and code at - http://blog.sqlauthority.com/2008/02/06/sql-server-import-csv-file-into-sql-server-using-bulk-insert-load-comma-delimited-file-into-sql-server/
and http://www.codeproject.com/Articles/439843/Handling-BULK-Data-insert-from-CSV-to-SQL-Server
BULK INSERT dbo.TableForBulkData
FROM 'C:\BulkDataFile.csv'
WITH
(
FIELDTERMINATOR = ',',
ROWTERMINATOR = '\n'
)
They don't show you how you can control where data is inserted.
Yes, you can do this. The easiest way is to just create a View that Selects from the target table, listing the columns that you want the data to go to, in the order that they appear in the source file. Then BULK INSERT to your View instead of directly to the Table.
When extracting data from a table (schema and data) I can do this by right clicking on the database and by going to tasks->Generate Scripts and it gives me all the data from the table including the create script, which is good.
This though gives me all the data from the table - can this be changed to give me only some of the data from the table? e.g only data on the table after a certain dtmTimeStamp?
Thanks,
I would recommend extracting your data into a separate table using a query and then using generate scripts on this table. Alternatively you can extract the data separately into a flatfile using the export data wizard (include your column headers and use comma seperators with double quote field delimiters).
To make a copy of your table:
SELECT Col1 ,Col2
INTO CloneTable
FROM MyTable
WHERE Col3 = #Condition
(Thanks to #MarkD for adding that)
