![]() ![]() ![]() PDO is probably much better solution, but you can also use '' for escaping: $rs5 = $db->GetAll($sql) Insert text dynamically with single quotes in PostgreSQL concat() or concat_ws() are typically no good for this purpose as those do not escape nested single quotes and backslashes.format() with the format specifier %L is equivalent to quote_nullable().There is also quote_ident() to double-quote strings where needed to get valid SQL identifiers. quote_literal() or quote_nullable() - the latter outputs the string NULL for null input.When dealing with values inside the database, there are a couple of useful functions to quote strings properly: SQL injection in Postgres functions vs prepared queries.It cannot alleviate the need to use prepared statements or some other method to safeguard against SQL injection in your application when user input is possible, though. That is all very useful for writing plpgsql functions or ad-hoc SQL commands. This is not the case with standard PostgreSQL clients like psql or pgAdmin. Pay attention if the $ character should have special meaning in your client software. Which can be nested any number of levels: $token2$Inner string: $token1$escape ' with ''$token1$ is nested$token2$ To further avoid confusion among dollar-quotes, add a unique token to each pair: $token$escape ' with ''$token$ If you have to deal with many single quotes or multiple layers of escaping, you can avoid quoting hell in PostgreSQL with dollar-quoted strings: 'escape '' with ''''' In old versions or if you still run with standard_conforming_strings = off or, generally, if you prepend your string with E to declare Posix escape string syntax, you can also escape with the backslash \: E'user\'s log'īackslash itself is escaped with another backslash. Plain single quotes (ASCII / UTF-8 code 39), mind you, not backticks `, which have no special purpose in Postgres (unlike certain other RDBMS) and not double-quotes ", used for identifiers. You can now configure Media Server to connect to the database (see Configure Media Server).Insert text with single quotes in PostgreSQLĮscaping single quotes ' by doubling them up → '' is the standard way and works of course: 'user's log' - incorrect syntax (unbalanced quote).In the ODBC Data Source Administrator dialog box, click OK to close the dialog box. In the MySQL Connector/ODBC Data Source Configuration dialog box, click OK to close the dialog box. If the connection failed, use the information in the message to resolve any issues.Ĭlick OK to close the Connection Test box. The Connection Test box opens containing a message describing whether the connection was successful. The name of the database that you created in Step 2. The password for the user account that connects to the database server. The user name to connect to the database server with. ![]() ![]() The port to use to communicate with the database server.

Is the user name that Media Server will connect as. GRANT EXECUTE ON databaseName.* TO userName GRANT SELECT, INSERT, UPDATE, DELETE ON databaseName.* TO userName Run the GRANT commands: GRANT CREATE TEMPORARY TABLES ON databaseName.* TO userName If security is not a consideration, grant all privileges. Grant privileges to the user that Media Server will connect as. Running the script non-interactively from the terminal ensures that the script terminates if an error occurs. Is the name of the database you created in Step 2. In the Windows Command Prompt, run the following command: mysql -u userName -p -v -D databaseName -e "source path/my.sql" This script sets up the database schema that Media Server requires. Run the my.sql script provided in the Media Server installation directory. Database nameĪny that is compatible with the encoding.įor example: CREATE DATABASE myDatabase CHARACTER SET utf8 COLLATE utf8_unicode_ci Run a CREATE DATABASE command to create a new database. In the Windows Command Prompt, run the command: mysql -u userName -p If the directory path is not added to the PATH variable, you must specify the mysql.exe file path in the Command Prompt to start psql. This step enables you to use the command mysql to start the mysql command-line tool from the Windows Command Prompt. ![]()
