C program mysql

Header files are required for program compilation and shared libraries are used at run-time. To check whether the package is already installed by this command. Before doing any database operation, we need to connect to the database server. This portion of the code does that. The returned pointer would be used as the handle for subsequent database operations. To access any database element like tables or any field of a table, we have to first connect to the database server.

If you want to access database running on a remote machine, you can specify the domain name or IP Address of the remote machine. Also we have to specify user id, password and database name. The above piece of code gets all the table names from the connected MySQL database. So, this while loop will return all available tables and print them. The outer while loop iterated through the rows and the inner for loop prints all columns of a row.

This will reduce your build time! Do I need libarys for that? And is that secure? Because some one said you should never store passwords in a file. Given that it's a source file that will be compiled into a binary, which is presumably going to be distributed, it's reasonably secure. Also, you'll need the mysql library, detailed on the linked page. It's not secure. It's easy to extract all strings from a binary to get the password.

But this is not the level at which security should happen. Kara 5, 15 15 gold badges 49 49 silver badges 56 56 bronze badges. Mats Stijlaart Mats Stijlaart 4, 7 7 gold badges 39 39 silver badges 58 58 bronze badges.

We provide connection handler, host name, user name and password parameters to the function.

The other four parameters are the database name, port number, unix socket and finally the client flag. We need superuser priviliges to create a new database. In our case, the statement creates a new database. Before we create a new table, we create a user that we will be using in the rest of the tutorial. We don't use any new MySQL function call here. We connect to testdb database. The fifth parameter is the database name.

Sometimes, we need to determine the id of the last inserted row. A new table is created. Three rows are inserted into the table. We determine the last inserted row id. We print the first three rows from the cars table. We also include the column headers. The first row contains the column headers. We get the column header names from this structure.
