![]() You can use above "foo" table data in your "see_me" table and perform read or write operations. INTO OUTFILE 'C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/out.txt' // out.txt will automatically created by mysqlīY running above commands you can perform read and write operations. Writing content to file(in "C:/ProgramData/MySQL/MySQL Server 8.0/Uploads" directory ) SELECT * FROM foo So it will copy entire txt data in 1st row of "content" column of "foo" table) by running above command entire txt data came to content column (mysql created only 1 row bcz we didn't mention lines terminated by. LINES STARTING BY '' TERMINATED BY '' // mysql creates new record for every line #FIELDS TERMINATED BY '' ENCLOSED BY '' ESCAPED BY '' LOAD DATA INFILE 'C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/check.txt' Longblob) // created temporary table called "foo" Later created a temporary table in which I am storing the data in check.txt CREATE TEMPORARY TABLE foo (id INT NOT NULL PRIMARY KEY AUTO_INCREMENT,content Read data from txt file (I have already created check.txt in "C:/ProgramData/MySQL/MySQL Server 8.0/Uploads"). Now we are ready to read file and create files using mysql. SHOW VARIABLES LIKE "secure_file_priv" //you will see path as 'C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/uploads' Now let's check directory of secure-file-priv it should 'C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/uploads' run the below command If it shows OFF we have to make it ON using following command. SHOW GLOBAL VARIABLES LIKE 'local_infile' ![]() I went to mysql workbench and checked some properties. I went to this location ( C:\ProgramData\MySQL\MySQL Server 8.0\my.ini) and checked the path secure-file-priv="C:/ProgramData/MySQL/MySQL Server 8.0/Uploads" and this location I created a file "check.txt" in which I have content. 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. First thing is we have to make sure whether we have proper permissions to read files from specific directory. So their respective column names from the table are listed in a comma-separated list within parentheses at the end of the statement.After working a lot the following thing worked for me. They are in a different order than found in the table. 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: To have MySQL ignore the first lines of text, add the IGNORE clause to the end of the LOAD DATA INFILE statement like this: Sometimes the first row of a data text file will contain column headings. 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. 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'). The first line of this statement specifies the path and the name of the file to import. 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. ![]()
