Replace Into Mysql Load From File With Update Query

Import CSV file to temporary table and then run the UPDATE.

DELAYED inserts and replaces were deprecated in MySQL 5.6. In MySQL 8.4, DELAYED is not supported. The server recognizes but ignores the DELAYED keyword, handles the replace as a nondelayed replace, and generates an ER_WARN_LEGACY_SYNTAX_CONVERTED warning REPLACE DELAYED is no longer

LOAD DATA LOCAL INFILE Loads data from the file path you specify. The LOCAL keyword allows you to read a file located on the client system not necessarily the server. INTO TABLE my_table Target table where the data will be inserted. Replace my_table with the actual table name.

I inherited a system in which all updates even to a single rowrecord to MySQL tables are not done using UPDATE table_name SET. Rather, they are done by Exporting the existing table to a CSV text file. Modifying the corresponding rows in the CSV file. Reloading the CSV file using LOAD DATA REPLACE INTO TABLE.

mysql -e quotLOAD DATA INFILE 'employee2.txt' INTO TABLE employee FIELDS TERMINATED BY ','quot 92 -u root -pMySQLPassword thegeekstuff Or, you can put that inside a shell script as shown below. In this example, the load-data.sh shell script has the above mysql command.

The non-LOCAL rules mean that the server reads a file named as .myfile.txt relative to its data directory, whereas it reads a file named as myfile.txt from the database directory of the default database.For example, if the following LOAD DATA statement is executed while db1 is the default database, the server reads the file data.txt from the database directory for db1, even though the

You should not do REPLACE because it is a mechanical DELETE and INSERT. As the MySQL Documentation says about REPLACE. Paragraph 2. REPLACE is a MySQL extension to the SQL standard.
