Default Re: [REL] MySQL Plugin (Now on github!)

The project has been moved from ******code to github

This plugin allows you to use MySQL in PAWN. It's currently being developed by Pain123/maddinat0r; you'll find all older versions, including source codes and sample scripts, from R5 to R7 at the bottom of this post and the latest release here.




How to install:


Move mysql.dll (windows) or mysql.so (linux) to your 'plugins/' directory. On windows you'll have to download the mysql library (libmysql.dll, see downloads) and move it to your main server directory. The server configuration (server.cfg) has to be edited aswell.
  • Windows
    Code:
    plugins mysql
  • Linux
    Code:
    plugins mysql.so


PAWN Scripting R5-R7: (a_mysql.inc)
  • Native functions: (All parameters in squared brackets are optional)
  • * = R5, R6 (supports threaded and non-threaded scripts)
  • * = R7 (supports only threaded scripts)
  • Caching guide - Click!

    • mysql_affected_rows( [connectionHandle = 1] ) **
    • mysql_close( [connectionHandle = 1] ) **
      • Make sure you call this on OnGameModeExit()/OnFilterscriptExit()
    • mysql_connect( const host[], const user[], const database[], const password[] ) *
    • mysql_connect( const host[], const user[], const database[], const password[] [, port = 3306] ) *
      • Returns a connection handle you can use for multiple connections
    • mysql_debug( enable = 1 ) **
      • Enables the debug modus and creates a log file named mysql.log
    • mysql_errno( [connectionHandle = 1] ) **
    • mysql_fetch_int( [connectionHandle = 1] ) *
    • mysql_fetch_field_row( string[], const fieldname[] [,connectionHandle = 1] ) **
    • mysql_fetch_float( &Float:result [,connectionHandle = 1] ) *
    • mysql_fetch_row_format( string[], const delimiter[] = "|" [,connectionHandle = 1] ) **
    • mysql_field_count( [connectionHandle = 1] ) **
    • mysql_format( connectionHandle, output[], format[], {Float,_}:... ) * (works on R6-2 aswell)
      pawn Code:
      Supported formats: (including precisions)
      - %e (escapes a string at once, no mysql_real_escape_string() needed)
      - %s (string)
      - %d / %i (integer)
      - %f (float)
      - %x (hex)
      - %b (binary)

      new szDestination[100];
      mysql_format(connectionHandle, szDestination, "SELECT * FROM `%s` WHERE `bar` = '%e' AND `foobar` = '%.2f' LIMIT %d", "foobar", "escape'me\"please", 1.2345, 1337);
      // the variable 'szDestination' contains now the formatted query (including the escaped string)
      mysql_query(szDestination);
    • mysql_free_result( [connectionHandle = 1] ) **
    • mysql_get_charset( destination[] [,connectionHandle = 1] ) **
    • mysql_insert_id( [connectionHandle = 1] ) **
    • mysql_num_rows( [connectionHandle = 1] ) **
    • mysql_num_fields( [connectionHandle = 1] ) **
    • mysql_ping( [connectionHandle = 1] ) **
      • Returns true (1) if the connection is alive, else (-1)
    • mysql_query( query[] [,resultid = (-1), extraid = (-1), connectionHandle = 1] ) *
      • Setting result id to something else than (-1), triggers the OnQueryFinish callback
    • mysql_query_callback( index, query[], callback[] [, extraid = (-1), connectionHandle = 1] ) **
      • Allows you to create custom callbacks for better structured coding (See sample_script.pwn below)
    • mysql_real_escape_string( const source[], destination[] [,connectionHandle = 1] ) **
    • mysql_reconnect( [connectionHandle = 1] ) **
    • mysql_reload( [connectionHandle = 1] ) **
    • mysql_retrieve_row( [connectionHandle = 1] ) **
      • Returns true (1) incase there are still rows to retrieve, else false (0)
    • mysql_set_charset( charset[] [,connectionHandle = 1] ) **
    • mysql_stat( const destination[] [,connectionHandle = 1] ) **
    • mysql_store_result( [connectionHandle = 1] ) **
    • mysql_warning_count( [connectionHandle = 1] ) **
    • cache_get_row( row, idx, dest[] [, connectionHandle = 1] ) *
    • cache_get_field( field_index, dest[] [, connectionHandle = 1] ) *
    • cache_get_data( &num_rows, &num_fields [, connectionHandle = 1] ) *
    • cache_get_field_content( row, const field_name[], dest[] [, connectionHandle = 1] ) *
    • enable_mutex( bool:enable ) *
      • Disable mutexes incase you experience random crashes. (seems to happen on some linux distros only)
    • mysql_function_query( connectionHandle, query[], bool:cache, callback[], format[], {Float,_}:... ) *
      pawn Code:
      mysql_function_query(connectionHandle, "UPDATE `foo` SET `bar` = 1", false, "CustomResponse", "dsf", 1337, "string", 1.5634);

      public CustomResponse(integer, string[], Float:float)
      {
          printf("Query successful executed. Data: %d | %s | %f", integer, string, float);
          return 1;
      }

  • Pawn Callback:
    • OnQueryFinish( query[], resultid, extraid, connectionHandle ) * - Sample usage (updated)
      • This is just called if you used the 'resultid' parameter in the query function
    • OnQueryError( errorid, error[], resultid, extraid, callback[], query[], connectionHandle ) *
    • OnQueryError( errorid, error[], callback[], query[], connectionHandle ) *


Compiling Notes:
  • Windows: Open the project file with Microsoft Visual C++ and click the build button. (MySQL Visual Studio/C++ is required of course)
  • Linux: Install gcc, gpp & mysql-client and type "make" in the source files folder.

Downloads: (for newer updates, use the github project site above!)

NOTE: DON'T USE VERSION R7 OR ABOVE IF YOU HAVE NO IDEA WHAT THREADING MEANS OR HOW IT WORKS. YOU MIGHT HARM YOUR SERVER WHEN USING IT NOT PROPERLY.
