sql - 插入时出现 TSQL 错误 "String or binary data would be truncated"

Question

在下面的代码中，我将值插入表中并收到错误“字符串或二进制数据将被截断。”

我的表定义:

CREATE TABLE urs_prem_feed_out_control
( 
bd_pr_cntl_rec_type  char(7)  NULL ,
pd_pr_cntl_acctg_dte char(6)  NULL ,
bd_pr_cntl_run_dte   char(10)  NULL ,
bd_pr_cntl_start_dte char(10)  NULL ,
bd_pr_cntl_end_dte   char(10)  NULL ,
bd_pr_cntl_rec_count char(16)  NULL ,
bd_pr_tot_premium    char(16)  NULL ,
bd_pr_tot_commission char(16)  NULL ,
fd_ctl_nbr           integer  NOT NULL 
)

DECLARE @cur_fd_ctl_nbr INT = 2, 
@acctg_cyc_ym_2 CHAR(6) = '201402',
@rundate CHAR (10) = CONVERT(CHAR(10),GETDATE(),101),
@cycle_start_dt DATETIME = '2014-02-17',
@cycle_end_dt DATETIME = '2014-02-24',
@record_count INT = 24704,
@tot_pr_premium DECIMAL(18,2) = 476922242,
@tot_pr_comm DECIMAL(18,2) = 2624209257

插入代码(我已将变量声明为常量值以进行测试，我从运行时获取这些值):

INSERT INTO urs_prem_feed_out_control
SELECT fd_ctl_nbr = @cur_fd_ctl_nbr,
       bd_pr_cntl_rec_type      = 'CONTROL',
       bd_pr_cntl_acctg_dte     = @acctg_cyc_ym_2,
       bd_pr_cntl_run_dte       = @rundate,
       bd_pr_cntl_start_dte     = CONVERT(CHAR(10),@cycle_start_dt,101),    
       bd_pr_cntl_end_dte       = CONVERT(CHAR(10),@cycle_end_dt,101),   
       bd_pr_cntl_rec_count     = RIGHT('0000000000000000' +     RTRIM(CONVERT(CHAR(16),@record_count)),16),                                         
       bd_pr_tot_premium        = CASE       
                                     WHEN @tot_pr_premium < 0
                                        THEN '-' + SUBSTRING(RIGHT('000000000000000' + LTRIM(RTRIM(CONVERT(VARCHAR,ABS(@tot_pr_premium)*100))),18),1,15)
                                     ELSE
                                        '+' + SUBSTRING(RIGHT('000000000000000' + LTRIM(RTRIM(CONVERT(VARCHAR,ABS(@tot_pr_premium)*100))),18),1,15)
                                     END,                                        
        bd_pr_tot_commission    = CASE       
                                     WHEN @tot_pr_comm < 0
                                        THEN '-' + SUBSTRING(RIGHT('000000000000000' + LTRIM(RTRIM(CONVERT(VARCHAR,ABS(@tot_pr_comm)*100))),18),1,15)
                                     ELSE
                                        '+' + SUBSTRING(RIGHT('000000000000000' + LTRIM(RTRIM(CONVERT(VARCHAR,ABS(@tot_pr_comm)*100))),18),1,15)
                                     END

当我单独查看每个值时，它们似乎都在表的可变长度限制内。知道为什么我会收到此错误吗？

谢谢!

插入查询的问题是插入顺序:

SELECT fd_ctl_nbr = @cur_fd_ctl_nbr,

此列必须在 INSERT 的最后定义，因为它是在创建表脚本中定义的最后一列。

将您的查询更改为:

   INSERT INTO #urs_prem_feed_out_control (fd_ctl_nbr, bd_pr_cntl_rec_type, pd_pr_cntl_acctg_dte, bd_pr_cntl_run_dte, bd_pr_cntl_start_dte, bd_pr_cntl_end_dte, bd_pr_cntl_rec_count, bd_pr_tot_premium, bd_pr_tot_commission)
SELECT fd_ctl_nbr = @cur_fd_ctl_nbr,
       bd_pr_cntl_rec_type      = 'CONTROL',
       bd_pr_cntl_acctg_dte     = @acctg_cyc_ym_2,
       bd_pr_cntl_run_dte       = @rundate,
       bd_pr_cntl_start_dte     = CONVERT(CHAR(10),@cycle_start_dt,101),    
       bd_pr_cntl_end_dte       = CONVERT(CHAR(10),@cycle_end_dt,101),   
       bd_pr_cntl_rec_count     = RIGHT('0000000000000000' +     RTRIM(CONVERT(CHAR(16),@record_count)),16),                                         
       bd_pr_tot_premium        = CASE       
                                     WHEN @tot_pr_premium < 0
                                        THEN '-' + SUBSTRING(RIGHT('000000000000000' + LTRIM(RTRIM(CONVERT(VARCHAR,ABS(@tot_pr_premium)*100))),18),1,15)
                                     ELSE
                                        '+' + SUBSTRING(RIGHT('000000000000000' + LTRIM(RTRIM(CONVERT(VARCHAR,ABS(@tot_pr_premium)*100))),18),1,15)
                                     END,                                        
        bd_pr_tot_commission    = CASE       
                                     WHEN @tot_pr_comm < 0
                                        THEN '-' + SUBSTRING(RIGHT('000000000000000' + LTRIM(RTRIM(CONVERT(VARCHAR,ABS(@tot_pr_comm)*100))),18),1,15)
                                     ELSE
                                        '+' + SUBSTRING(RIGHT('000000000000000' + LTRIM(RTRIM(CONVERT(VARCHAR,ABS(@tot_pr_comm)*100))),18),1,15)
                                     END

这样做也可以。请注意，INSERT 中 SELECT 中的第一列正是您在问题中提供的方式。

希望这有帮助!!!
