Examples

Reading Data (Using inline)

new stmt_readloop = MySQL_PrepareStatement(MySQLHandle, "SELECT * FROM spawns");

// Run Threaded on statement
inline OnSpawnsLoad() {
    new
        spawnID,
        Float:spawnX,
        Float:spawnY,
        Float:spawnZ,
        Float:spawnA;

    MySQL_BindResultInt(stmt_readloop, 0, spawnID);
    MySQL_BindResultFloat(stmt_readloop, 1, spawnX);
    MySQL_BindResultFloat(stmt_readloop, 2, spawnY);
    MySQL_BindResultFloat(stmt_readloop, 3, spawnZ);
    MySQL_BindResultFloat(stmt_readloop, 4, spawnA);

    while(MySQL_Statement_FetchRow(stmt_readloop)) {
        printf("%i, %.3f, %.3f, %.3f", spawnID, spawnX, spawnY, spawnZ, spawnA);
    }
    MySQL_StatementClose(stmt_readloop);
}
MySQL_ExecuteThreaded_Inline(stmt_readloop, using inline OnSpawnsLoad);

Writing Data

new Statement:stmt_insert = MySQL_PrepareStatement(MySQLHandle, "INSERT INTO accounts(username, password, salt, money, kills, deaths) VALUES (?,?,?,?,?,?)");

// Arrow values in questions (first 0, second is 1, etc ...)
MySQL_Bind(stmt_insert, 0 , "patrickgtr");
MySQL_Bind(stmt_insert, 1 , "patrickgtrpassword");
MySQL_Bind(stmt_insert, 2 , "pgtrhash");
MySQL_BindInt(stmt_insert, 3, 100);
MySQL_BindInt(stmt_insert, 4, 200);
MySQL_BindInt(stmt_insert, 5, 300);

MySQL_ExecuteParallel(stmt_insert);
MySQL_StatementClose(stmt_insert);
