From this tutorial developers will obtain functional advises about insertion of Bulk data using SQL BULK Insert statement in Microsoft SQL Server.
The t-sql bulk insert is process that is produced by DBMS (Database Management System). T sql bulk insert is operation, activity or procedure given by a DBMS (database management system) to load multiple rows of data in form of text files into a database table directly.
BULK insert Statement is a Transact – SQL (Server Query Language) statement that implement a sized data – loading procedure. Through BULK statement multiple rows, bundle of rows added or insert into SQL Server tables. Data can read from external back – to – back file using BULK Statement.
SQL BULK INSERT Query:
Bulk insert Table – name
From ‘Path of text File’
ROWS_PER_BATCH = 10000,
This is Bulk insert Query of SQL server database. Where
Table – name is database table name that is created in SQL Server. Path of text File Suppose we have a text file having name Bulktbl.txt in E Directory of computer then we provide path in this format ’E:\Bulktbl.txt’
The further aspects of the BULK Insert SQL Command are available here BULK Insert
Actually, the sql BULK insert Query is a rich T-SQL (Transact SQL) command which have logic to setup error, batch – size, activate, and so on.
Method of run SQL BULK insert Query:
Here we discuss the sql bulk insert example. If we want to add some personal data of some client in database table like we want to add client id, client name, client contact Number etc . Then we discuss the method to apply BULK insert Query in SQL SERVER in following these steps:
- Create a text file or sql bulk insert format file included values that we want to add in database table like in this format show in picture below.
- Open SQL server right click on database and choose new database option give the name of database. However, Database has been created.
- Open created database and then right click on table choose new table create three columns first one ID column 2nd Name column 3rd Contact Number column. Save table and give the database table name. We set primary key to first ID column because every client have separate client ID. Shown in picture below:
- Click on New Query on top left of SQL Server blank field shown. Now right BULK insert query in this format.
Bulk insert Bulktbl
From ‘E:\ Bulktbl.txt’
Click on Execute button. OOOh there is problem sql bulk insert error file shown below:
This sql bulk insert error handle or this problem remove when we select our database on top left list text box by rolling below.
Finally text file sql bulk insert data has been added in SQL Server database. Right click on database table Clienttbl and choose the option top 1000 rows. Open the table and data have been added.
Use Try Catch block to handle rollback and transaction. Try catch block also use for sql bulk insert distinct like that:
BULK INSERT TABLE – NAME
FROM ‘PATH OF TEXT FILE’
FIELDTERMINATOR = ‘,’,
ROWTERMINATOR = ‘\n’,
ROWS_PER_BATCH = 10000,
SQL BULK INSERT Benefits :
Results after using BULK insert process better than if a coder use Insert statement individually for each row added in Database. The performance is also better through this process. LOC (Line of code also) also sum-up using this statement and save time.
BULK Insert statement fills data into a database table from data file. This process is like that BCP Command provided by the in option. Although, SQL server read the data file.
