mysql:tldr:58b37
This command is used to interactively execute a single SQL query or a set of SQL queries stored in a file using the MySQL command-line client.
Here is a breakdown of the command:
-
mysql
: This is the command to run the MySQL command-line client. -
-e "source ${filename-sql}"
: The-e
option allows you to specify a single query or a set of queries to execute. In this case, the query issource ${filename-sql}
. Thesource
command is used to execute SQL statements stored in a file.${filename-sql}
is a placeholder for the name of the SQL file you want to execute. -
${database_name}
: This is the name of the MySQL database you want to connect to. It specifies the database in which the queries will be executed.
To use this command, you need to replace ${filename-sql}
with the actual name of the SQL file you want to execute, and ${database_name}
with the name of your MySQL database. For example, if you have an SQL file named data.sql
and want to execute the queries in a database named mydatabase
, the command would look like this:
mysql -e "source data.sql" mydatabase
Executing this command will connect to the specified database and execute the SQL queries from the data.sql
file. The results or any error messages will be printed on the terminal.
