Migrating data from Access into SQL Server. SQL Server table defines inst_id, cons_code, and eff_date_time column as primary key. The eff_date_time data coming from access is not unique so I was attempting to increment the seconds field by one second so I would have a unique datetime. I can’t get DATEADD to increment the date by 1 second. Attached is my code. What am I doing wrong???

USE [CON-INST]  
GO

DECLARE  
@cv_InstId      VARCHAR(25),  
@cv_ConsCode    VARCHAR(10),  
@cv_EffDateTime DATETIME,  
@lv_count INT  

DECLARE BumpDate_Cursor CURSOR  
STATIC  
FOR  
          SELECT inst_id, cons_code, eff_date_time  
            FROM [CON-INST].[dba].[constants_temp]  
           ORDER BY inst_id  

OPEN BumpDate_Cursor

FETCH FIRST FROM BumpDate_Cursor  
 INTO @cv_InstId, @cv_ConsCode, @cv_EffDateTime

SET @lv_count = 1

// Debug statements  
PRINT '@cv_InstId = ' + @cv_InstId  
PRINT '@cv_ConsCode = ' + @cv_ConsCode  
PRINT '@cv_EffDateTime = ' + CONVERT(VARCHAR, @cv_EffDateTime)  
PRINT '@lv_count = ' + CONVERT(VARCHAR, @lv_count)  

-- Loop to iterate thru instruments identifying the various constant
types that are needed, i.e. the column names - constant 1, constant 2,
constant 3, station, offset, etc.  
WHILE @@FETCH_STATUS = 0  
-- do processing  
BEGIN  
  PRINT '@lv_count before = ' + CONVERT(VARCHAR, @lv_count)  
  PRINT CONVERT(VARCHAR, @cv_EffDateTime, 121)  
  IF (CONVERT(VARCHAR, @cv_EffDateTime,121) = '1901-01-01 17:00:00.000')  
     BEGIN  
        UPDATE [CON-INST].[dba].[constants_temp]  
           SET eff_date_time = DATEADD(second, @lv_count, eff_date_time)  
         WHERE inst_id = @cv_InstId and cons_code = @cv_ConsCode;  
        PRINT CONVERT(VARCHAR, @cv_EffDateTime, 121)  
     END  

  FETCH NEXT FROM BumpDate_Cursor  
   INTO @cv_InstId, @cv_ConsCode, @cv_EffDateTime  

  SET @lv_count = @lv_count + 1  
  PRINT '@lv_count after = ' + CONVERT(VARCHAR, @lv_count)  
END
