Loadrunner測試數(shù)據(jù)庫性能,測試SQL語句性能的腳本例子

Loadrunner測試數(shù)據(jù)庫性能，測試SQL語句性能的腳本例子此代碼為Loadrunner8通過CAPI類型的Vuser測試MySQL性能，或者測試sql語句性能的腳本。這東西很少有人用，網(wǎng)上資料很少，一般測試B/S的很多。viewplaincopytoclipboardprint?/*需要的表結(jié)構(gòu)如下CREATETABLE、test_data、(、order_id'BIGINTUNSIGNEDNOTNULLCOMMENT'Ordernumbers.Mustbeunique.',、status、BOOLNOTNULLDEFAULT'O'COMMENT'Whetherdatahasbeenusedornot.Avalueof0meansFALSE.','date_used、DATETIMENULLCOMMENT'Date/timethatthedatawasused.',UNIQUE('order_id'))ENGINE=innodbCOMMENT='LoadRunnertestdata';*/Action(){intrc;intdb_connection;//數(shù)據(jù)庫連接intquery_result;//查詢結(jié)果集MYSQL_RESchar**result_row;//查詢的數(shù)據(jù)衕char*server="localhost";char*user="root";char*password="123456";char*database="test";intport=33O6;intunix_socket=NULL;intflags=O;//找到libmysql.dll的所在位置.rc=lr_load_dll("C:\\ProgramFiles\\MySQL\\MySQLServer5.1\\bin\\libmysql.dll");if(rc!=O){lr_error_message("Couldnotloadlibmysql.dll");lr_abort();}//創(chuàng)建MySQL對象db_connection=mysql_init(NULL);if(db_connection==NULL){lr_error_message("Insufficientmemory");lr_abort();}//連接到MySQL數(shù)據(jù)庫rc=mysql_real_connect(db_connection,server,user,password,database,port,unix_socket,flags);if(rc==NULL){lr_error_message("%s",mysql_error(db_connection));mysql_close(db_connection);lr_abort();}//向數(shù)據(jù)庫插入數(shù)據(jù)//此處的{ORDER_ID}是一個參數(shù)，簡單測試時可以用一個常數(shù)代替lr_save_string(lr_eval_string("INSERTINTOtest_data(order_id)VALUES({ORDER_ID})"),"paramInsertQuery");rc=mysql_query(db_connection,lr_eval_string("{paramInsertQuery}"));if(rc!=0){lr_error_message("%s",mysql_error(db_connection));mysql_close(db_connection);lr_abort();}//從數(shù)據(jù)庫讀取一個數(shù)據(jù)并顯示rc=mysql_query(db_connection,"SELECTorder_idFROMtest_dataWHEREstatusISFALSELIMIT1");if(rc!=0){lr_error_message("%s",mysql_error(db_connection));mysql_close(db_connection);lr_abort();}query_result=mysql_use_result(db_connection);if(query_result==NULL){lr_error_message("%s",mysql_error(db_connection));mysql_free_result(query_result);mysql_close(db_connection);lr_abort();}//如果結(jié)果集包含多行數(shù)據(jù)，需要多次調(diào)用mysql_fetch_row直到返回NULLresult_row=(char**)mysql_fetch_row(query_result);if(result_row==NULL){lr_error_message("Didnotexpecttheresultsettobeempty");mysql_free_result(query_result);mysql_close(db_connection);lr_abort();}//保存參數(shù)，用于刪除這行數(shù)據(jù)lr_save_string(result_row[0],"paramOrderID");lr_output_message("OrderIDis:%s",lr_eval_string("{paramOrderID}"));mysql_free_result(query_result);//在事務(wù)里更新一行數(shù)據(jù)，需要用InnoDB引擎rc=mysql_query(db_connection,"BEGIN");//啟動事務(wù)if(rc!=0){lr_error_message("%s",mysql_error(db_connection));mysql_close(db_connection);lr_abort();}//使用"FORUPDATE"鎖住要更新的數(shù)據(jù)行rc=mysql_query(db_connection,"SELECTorder_idFROMtest_dataWHEREstatusISFALSELIMIT1FORUPDATE");if(rc!=0){lr_error_message("%s",mysql_error(db_connection));mysql_close(db_connection);lr_abort();}query_result=mysql_use_result(db_connection);if(query_result==NULL){lr_error_message("%s",mysql_error(db_connection));mysql_free_result(query_result);mysql_close(db_connection);lr_abort();}result_row=(char**)mysql_fetch_row(query_result);if(result_row==NULL){lr_error_message("沒有查詢到結(jié)果");mysql_free_result(query_result);mysql_close(db_connection);lr_abort();}lr_save_string(result_row[0],"paramOrderID");lr_output_message("OrderIDis:%s",lr_eval_string("{paramOrderID}"));mysql_free_result(query_result);lr_save_string(lr_eval_string("UPDATEtest_dataSETstatus=TRUE,date_used=NOW()WHEREorder_id='{paramOrderID}'"),"paramUpdateQuery");rc=mysql_query(db_connection,lr_eval_string("{paramUpdateQuery}"));if(rc!=0){lr_error_message("%s",mysql_error(db_connection));mysql_close(db_connection);lr_abort();}rc=mysql_query(db_connection,"COMMIT");//提交事務(wù)if(rc!=0){lr_error_message("%s",mysql_error(db_connection));mysql_close(db_connection);lr_abort();}//再次查找數(shù)據(jù)，應(yīng)該為空了，因為前面的事務(wù)更新了標(biāo)志rc=mysql_query(db_connection,"SELECTorder_idFROMtest_dataWHEREstatusISFALSELIMIT1");if(rc!=0){lr_error_message("%s",mysql_error(db_connection));mysql_close(db_connection);lr_abort();}query_result=mysql_use_result(db_connection);if(query_result==NULL){lr_error_message("%s",mysql_error(db_connection));mysql_free_result(query_result);mysql_close(db_connection);lr_abort();}result_row=(char**)mysql_fetch_row(query_result);if(result_row==NULL){lr_output_message("Resultsetisemptyasexpected");mysql_free_result(query_result);}else{lr_error_message("Didnotexpecttheresultsettocontainanyrows");mysql_free_result(query_result);mysql_close(db_connection);lr_abort();//刪除數(shù)據(jù)lr_save_string(lr_eval_string("DELETEFROMtest_dataWHEREorder_id='{paramOrderID}'"),"paramDeleteQuery");rc=mysql_query(db_connection,lr_eval_string("{paramDeleteQuery}"));if(rc!=0){lr_error_message("%s",mysql_error(db_connection));mysql_close(db_connection);lr_abort();}//釋放MySQL資源mysql_close(db_connection);return0;}/*需要的表結(jié)構(gòu)如下CREATETABLE、test_data、(、order_id'BIGINTUNSIGNEDNOTNULLCOMMENT'Ordernumbers.Mustbeunique.',、status、BOOLNOTNULLDEFAULT'O'COMMENT'Whetherdatahasbeenusedornot.Avalueof0meansFA
