If you're not sure of your regular expressions (either search and/or replace), then backup your file.ģ) the circumflex (^) is part of the regular expression search pattern. In the case where one wishes to run multiple commands at once.Ģ) -i means perform the edit "inplace" - no new file is created. $> mysql -u my_user -pmy_password my_schema mysql_stuff.txt (bash or cygwin)Īnd then add SOURCE ( space) to the beginning of each lineġ) -e not strictly necessary in this case, see here. Or, you can use the mysql client from the shell. To load the text file pet.txt into the pet table, use this statement: mysql> LOAD DATA LOCAL INFILE /path/pet. So their respective column names from the table are listed in a comma-separated list within parentheses at the end of the statement.Mysql> SOURCE mysql_stuff.txt or mysql> \. They are in a different order than found in the table. Insert text file into MySQL import java.io.File import java.io.FileInputStream import import import java.sql. In this example, only three of the columns possible are contained in the data text file. Below is an example of how this might look: If the fields in the data text file are not in the same order or the file doesn't contain the same number of columns as the receiving table, a list of columns and their order needs to be given. ![]() LOAD DATA LOW_PRIORITY INFILE '/tmp/data.txt' If the fields in the data text file are surrounded by characters like double-quotes, add the ENCLOSED BY clause like so: The data is a CSV file with comma as separator and timestamp and string field value quoted by single quoteshow can i insert it into TDengine I am now using SQL to achieve that Single row or multiple rows specified with VALUES can be inserted into a specific table. To have MySQL ignore the first lines of text, add the IGNORE clause to the end of the LOAD DATA INFILE statement like this: MySQL Database name: XmlDate Database table: PerformanceReport I have already created the table with all the destination fields. The statement would need to be entered like this: Suppose also that the fields are terminated with a. However, suppose that the rows in the text file start and end with double-quotes and a Windows hard-return (i.e., a return and a line-feed). If lines are terminated by a line-feed ( \n), it doesn't need to be specified since it's the default. The third line above specifies the vertical bar as the field delimiter.įor some text files, you may need to specify the line terminator. INTO OUTFILE can also be used with a TABLE statement when you want to dump all columns of a table into a text file. The INTO TABLE clause specifies the database and the table to import into. For a Windows server, the forward-slashes are still used for the file's path, but a drive may need to be specified at the beginning of the path (e.g, 'c:/tmp/prospects.txt'). In this article we describe the process of importing data from a text file into a database, and also we discuss questions concerning problems with MySQL import and the ways of solving these problems. The first line of this statement specifies the path and the name of the file to import. 1 14706 When working with databases it is always necessary to import data or schemas. Below is what you might enter through the mysql client to import the data into the table table1 Suppose further that within the file there is one record per line and that the fields of each are separated by a vertical bar. As an example, suppose that you have a text file called data.txt in the /tmp directory. If you have a plain text file that contains data, the LOAD DATA INFILE statement can be used to import it into MySQL. How do I import data into MySQL from a simple text file?. ![]()
