Question

我有以下查询，用于动态地向表中插入数据，我检查了表和参数的数据类型，我通过两者是相同的，但仍然有以下错误：

4 1 Msg 245，Level 16，State 1，Line 43 将varchar值'insert转换为tblAccessRights（RoleId，CustomerId，IsCustomerExclusive，SubcustomerId，
）时转换失败 IsSubCustomerExclusive，ClinicId，CreatedBy，CreatedDate，请将isDeleted，IsActive）
values（'到数据类型int。

这是我的查询plz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????，plz help

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

Answer 1

样本：

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

convert text into number in mysql query

Answer 2

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

你应该尝试像'foo'+ CONVERT（varchar，@ RoleId）+'ba'这样的事情比你得到的''foo 24 ba'

将@ sql ='insert插入tblAccessRights（RoleId，CustomerId，IsCustomerExclusive，SubcustomerId，
IsSubCustomerExclusive，ClinicId，CreatedBy，CreatedDate，请将isDeleted，IsActive）
值（'+ CONVERT（varchar，@ RoleId）+'，'+ CONVERT（varchar，@ CustomerId）+ ...

使用动态插入数据类型varchar插入数据时出错无法转换为int
