【问题描述】：

我有以下查询，用于动态插入数据到表中，我检查了表的数据类型和我传递的参数是否相同，但仍然出现以下错误：

4 1 消息 245，第 16 级，状态 1，第 43 行将 varchar 值 'insert 转换为 tblAccessRights (RoleId,CustomerId,IsCustomerExclusive,SubcustomerId,
IsSubCustomerExclusive,ClinicId,CreatedBy,CreatedDate,IsDeleted,IsActive)
values(' 到数据类型 int.

这是我的查询请检查

declare @SubcustomerId varchar(max)    
set @SubcustomerId = '4,5'  

declare @IsSubCustomerExclusive varchar(max)
set @IsSubCustomerExclusive = '1,0'
declare  
@RoleId int ,    
@CustomerId int,    
@IsCustomerExclusive int,    

@ClinicId varchar(max)=null,    
@CreatedBy int,    
@CreatedDate datetime,    
@ModifiedBy int,    
@ModifiedDate datetime,    
@IsDeleted bit,    
@IsActive bit,    
@RoleName varchar(50) 
set  
@RoleId =24     
set @IsCustomerExclusive =0    

set @ClinicId =null  
set @CreatedBy=null  
set @CreatedDate =null   
set @ModifiedDate =null    
set @IsDeleted=0    
set @IsActive =1    
set @RoleName='ts1'   


declare @sql varchar(max)    

while(len(@SubcustomerId) > 0 and LEN(@IsSubCustomerExclusive)>=0)  
begin    
  print left(@SubcustomerId, charindex(',', @SubcustomerId+',')-1)  
  print left(@IsSubCustomerExclusive, charindex(',', @IsSubCustomerExclusive+',')-1) 
 if(LEN(@IsSubCustomerExclusive)=0 )  
 begin  
   set @IsSubCustomerExclusive='0'  
 end  

   set @sql='insert into tblAccessRights        (RoleId,CustomerId,IsCustomerExclusive,SubcustomerId,    
IsSubCustomerExclusive,ClinicId,CreatedBy,CreatedDate,IsDeleted,IsActive)    
values('+@RoleId+','+@CustomerId+','+@IsCustomerExclusive+','+left(@SubcustomerId,   charindex(',', @SubcustomerId+',')-1)+',    
  '+left(@IsSubCustomerExclusive, charindex(',',  @IsSubCustomerExclusive+',')-1)+','+@ClinicId+','+@CreatedBy+','+@CreatedDate+','+@IsDeleted      +','+@IsActive+')'
print @sql    

   --exec(@sql)    
     set @SubcustomerId = stuff(@SubcustomerId, 1, charindex(',', @SubcustomerId+','), '')   
       set @IsSubCustomerExclusive = stuff(@IsSubCustomerExclusive, 1, charindex(',',  @IsSubCustomerExclusive+','), '')     
        end

我在查询中做错了吗？？？，请帮助

pid int 
RoleId  int 
CustomerId  int 
IsCustomerExclusive int 
SubcustomerId   varchar(MAX)    
IsSubCustomerExclusive  varchar(MAX)    
ClinicId    varchar(MAX)    
CreatedBy   varchar(50) 
CreatedDate datetime    
ModifiedBy  varchar(50) 
ModifiedDate    datetime    
IsDeleted   bit 
IsActive    bit

这是我的表结构

【问题讨论】：

您可以将您的 SQL 字符串作为参数传递，其中需要一个 int。
是mysql还是SQL server？您添加了两个标签。我猜是 SQL 服务器
@Pleun:它是sql server 2008

标签： sql-server sql-server-2008-r2 dynamicquery

【解决方案1】：

示例：

   SELECT field,CONVERT(SUBSTRING_INDEX(field,'-',-1),UNSIGNED INTEGER) AS num
    FROM table
    ORDER BY num;

convert text into number in mysql query

【解决方案2】：

你的 RoleID 是一个整数，所以你尝试做一个隐式转换：'insert into table ......' as int

你应该尝试做类似 'foo' + CONVERT(varchar,@RoleId) + ' ba' 比你得到的：'foo 24 ba'

http://technet.microsoft.com/en-us/library/aa226054%28v=sql.80%29.aspx

设置@sql='insert into tblAccessRights (RoleId,CustomerId,IsCustomerExclusive,SubcustomerId,
IsSubCustomerExclusive,ClinicId,CreatedBy,CreatedDate,IsDeleted,IsActive)
values(' + CONVERT(varchar, @RoleId) + ',' + CONVERT(varchar, @CustomerId) + ...

【讨论】：

您将 @RoleID 声明为 int。如果您尝试将 int 与 varchar 连接，dbms 会尝试将 varchar 转换为 int，但您想以另一种方式转换：int as varchar。
看看引用：technet.microsoft.com/en-us/library/aa276862%28v=sql.80%29.aspx 它说：返回具有最高优先级的参数的数据类型。有关详细信息，请参阅数据类型优先级。
