Import CSV File Into My. SQL Table. This tutorial shows you how to use the LOAD DATA INFILE statement to import CSV file into My. SQL table. The  LOAD DATA INFILE statement allows you to read data from a text file and import the files data into a database table very fast. Before importing the file, you need to prepare the following A database table to which the data from the file will be imported. A CSV file with data that matches with the number of columns of the table and the type of data in each column. The account, which connects to the My. SQL database server, has FILE and INSERT privileges. Suppose we have a table named discounts with the following structure We use CREATE TABLE statement to create the discounts table as follows. CREATE TABLE discounts. INT NOT NULL AUTOINCREMENT. Softwares De Conforto. VARCHAR2. 55 NOT NULL. DATE NOT NULL. amount DECIMAL1. NULL. PRIMARY KEY id. INTNOT NULLAUTOINCREMENT,    title. VARCHAR2. 55NOT NULL,    expireddate.

Explanation First, we create the dialog by calling the appropriate Constructor. Then, we call ShowModal. That opens the dialog Modal means that the user cannot. DATENOT NULL,The following  discounts. The following statement imports data from the  c tmpdiscounts. LOAD DATA INFILE c tmpdiscounts. INTO TABLE discounts. FIELDS TERMINATED BY ,. ENCLOSED BY. LINES TERMINATED BY n. IGNORE 1 ROWS LOAD DATAINFILEc tmpdiscounts. The field of the file is terminated by a comma indicated by  FIELD TERMINATED BY, and enclosed by double quotation marks specified by ENCLOSED BY. Each line of the CSV file is terminated by a newline character indicated by LINES TERMINATED BY n. Because the file has the first line that contains the column headings, which should not be imported into the table, therefore we ignore it by specifying  IGNORE 1 ROWS option. Now, we can check the discounts table to see whether the data is imported. Transforming data while importing. Sometimes the format of the data does not match the target columns in the table. In simple cases, you can transform it by using the SET clause in the  LOAD DATA INFILE statement. Suppose the expired date column in the  discount2. Safe 12 2 Full Cracked'>Safe 12 2 Full Cracked.

It is possible to import data from client local computer to a remote My. SQL database server using the LOAD DATA INFILE statement. When you use the LOCAL option in the LOAD DATA INFILE, the client program reads the file on the client and sends it to the My. SQL server. The file will be uploaded into the database server operating systems temporary folder e. C windowstemp on Windows or  tmp on Linux. This folder is not configurable or determined by My. SQL. Lets take a look at the following example. LOAD DATA LOCAL INFILE c tmpdiscounts. INTO TABLE discounts. FIELDS TERMINATED BY ,. ENCLOSED BY. LINES TERMINATED BY n. IGNORE 1 ROWS LOAD DATALOCALINFILE  c tmpdiscounts. The only difference is the LOCAL option in the statement. If you load a big CSV file, you will see that with the LOCAL option, it will be a little bit slower to load the file because it takes time to transfer the file to the database server. The account that connects to My. SQL server doesnt need to have the FILE privilege to import the file when you use the LOCAL option. Importing the file from client to a remote database server using  LOAD DATA LOCAL has some security issues that you should be aware of to avoid potential security risks. Importing CSV file using My. SQL Workbench. My. SQL workbench provides a tool to import data into a table. It allows you to edit data before making changes. The following are steps that you want to import data into a table Open table to which the data is loaded. Click Import button, choose a CSV file and click Open button. Review the data, click Apply button. My. SQL workbench will display a dialog  Apply SQL Script to Database, click Apply button to insert data into the table. We have shown you how to import CSV into My. SQL table using LOAD DATA LOCAL and using My. SQL Workbench. With these techniques, you can load data from other text file formats such as tab delimited.
