Question

我创建了以下存储过程以将数据插入数据库：

CREATE DEFINER=`PotatoHead`@`%` PROCEDURE `InsertIntoTable`(in    
            tablename varchar(45),in ID varchar(45),in Project 
            varchar(45),in Variant varchar(45),
            in ReleaseVersion varchar(45) ,
            in TestBenchID varchar(45) ,
            in TestCaseID int(11) ,
            in TestCaseNamespace varchar(100) ,
            in TestCaseName varchar(45),
            in TestCaseDomain varchar(45) ,
            in TestType varchar(45) ,
            in HardwareVersion varchar(4000) ,
            in SoftwareVersion varchar(4000),
            in Result varchar(45) ,
            in Comment varchar(4000),
            in Duration varchar(45) ,
            in StartTime varchar(45) ,
            in EndTime varchar(45)  )
BEGIN

  SET @sql = CONCAT('Insert into ', tablename );
  SET @sql = CONCAT('ID,Project,Variant,');
  SET @sql = CONCAT('ReleaseVersion,');
  SET @sql = CONCAT('TestBenchID ,');
  SET @sql = CONCAT('TestCaseID ,');
  SET @sql = CONCAT('TestCaseNamespace ,');
  SET @sql = CONCAT('TestCaseName ,');
  SET @sql = CONCAT('TestCaseDomain ,');
  SET @sql = CONCAT('TestType ,');
  SET @sql = CONCAT('HardwareVersion ,');
  SET @sql = CONCAT('SoftwareVersion ,');
  SET @sql = CONCAT('Result ,');
  SET @sql = CONCAT('Comment ,');
  SET @sql = CONCAT('Duration ,');
  SET @sql = CONCAT('StartTime ,');
  SET @sql = CONCAT('EndTime) VALUES (');
    SET @sql = CONCAT(ID,',',Project,',',Variant,',',
    ReleaseVersion,',',
    TestBenchID,',',
    TestCaseID,',',
    TestCaseNamespace ,',',
    TestCaseName ,',',
    TestCaseDomain ,',',
    TestType ,',',
    HardwareVersion ,',',
    SoftwareVersion ,',',
    Result ,',',
    Comment ,',',
    Duration ,',',
    StartTime ,',',
    EndTime,');');
PREPARE s FROM @sql;
EXECUTE s;
DEALLOCATE PREPARE s;

 END

当我尝试使用以下查询调用它时：

Call InsertIntoTable('oablp1992','id','project','variant',
    'releaseversion',
    'testbenchid',
    1,
    'testcasenamespace',
    'testcasename',
    'Domain',
    'type',
    'hardware',
    'software',
    'result',
    'comment',
    'Duration',
    'starttime',
    'endtime');


Insert into oablp1992(ID,Project,Variant,
    ReleaseVersion,
        TestBenchID ,
    TestCaseID ,
        TestCaseNamespace ,
    TestCaseName ,
    TestCaseDomain ,
    TestType ,
        HardwareVersion ,
        SoftwareVersion ,
    Result ,
    Comment ,
    Duration ,
    StartTime ,
    EndTime) VALUES('id','project','variant',
    'releaseversion',
    'testbenchid',
        '1',
        'testcasenamespace',
        'testcasename',
        'Domain',
        'type',
        'hardware',
        'software',
    'result',
        'comment',
        'Duration',
        'starttime',
        'endtime');

我收到以下错误：

错误代码：1064。您的SQL语法有错误;检查与MySQL服务器版本对应的手册，以便在第1行的'id，project，variant，releaseversion，testbenchid，1，testcasenamespace，testcasename，D'附近使用正确的语法

如何解决这个问题？

如果使用明确区分参数与列名的命名约定，那将更加清晰。但也许这就是你想要的。注意使用ascii字符39（单引号）。

drop procedure if exists `InsertIntoTable`;
delimiter $$
CREATE PROCEDURE `InsertIntoTable`(in    
            tablename varchar(45),
                in ID varchar(45),

                in Variant varchar(45),
            in ReleaseVersion varchar(45) ,
            in TestBenchID varchar(45) ,
            in TestCaseID int(11) ,
            in TestCaseNamespace varchar(100) ,

  'Result,' ,
  CHAR(96),'Comment',CHAR(96),',' ,

 Call InsertIntoTable('oablp1992','id','project','variant',
    'releaseversion',
    'testbenchid',
    1,
    'testcasenamespace',
    'testcasename',
    'Domain',
    'type',
    'hardware',
    'software',
    'result',
    'comment',
    'Duration',
    'starttime',
    'endtime');

哪个产生这个sql语句

Insert into oablp1992(
ID,Project,Variant,ReleaseVersion,TestBenchID,TestCaseID,TestCaseNamespace,
TestCaseName,TestCaseDomain,TestType,HardwareVersion,SoftwareVersion,
Result,`Comment`,Duration,StartTime,EndTime) 
values (
'id','project','variant','releaseversion','testbenchid','1','testcasenamespace',
'testcasename','Domain','type','hardware',
'software','result','comment','Duration','starttime','endtime');

当你希望将它传递给sql时，不要忘记删除注释掉的行。
