我想从包含大约十万条记录的文本文件中导入数据

我正在使用批量插入这样做

BULK
INSERT vw_bulk_insert_test
FROM '\\server\c$\csvtext.txt'--\\server\SQLEXPRESS\csvtest.txt'
WITH
(FIRSTROW=2,
check_CONSTRAINTS,
FIELDTERMINATOR = '~',
ROWTERMINATOR = '\n'
)
GO

但是在插入之前，我想在不使用游标的情况下验证每一列的值。就像第二行将包含除 unit_number(Column) 之外的所有字段的值一样，那么它应该创建一个错误日志，指定缺少 unit_number 值。

就个人而言，我会批量插入临时表，然后使用 TSQL 或 TSQL 以为此目的创建的存储过程的形式将临时表中的内容验证/转换到最终将驻留的表中。

你有这个语法

BULK INSERT 
   [ database_name . [ schema_name ] . | schema_name . ] [ table_name | view_name ] 
      FROM 'data_file' 
     [ WITH 
    ( 
   [ [ , ] BATCHSIZE = batch_size ] 
   [ [ , ] CHECK_CONSTRAINTS ] 
   [ [ , ] CODEPAGE = { 'ACP' | 'OEM' | 'RAW' | 'code_page' } ] 
   [ [ , ] DATAFILETYPE = 
      { 'char' | 'native'| 'widechar' | 'widenative' } ] 
   [ [ , ] FIELDTERMINATOR = 'field_terminator' ] 
   [ [ , ] FIRSTROW = first_row ] 
   [ [ , ] FIRE_TRIGGERS ] 
   [ [ , ] FORMATFILE = 'format_file_path' ] 
   [ [ , ] KEEPIDENTITY ] 
   [ [ , ] KEEPNULLS ] 
   [ [ , ] KILOBYTES_PER_BATCH = kilobytes_per_batch ] 
   [ [ , ] LASTROW = last_row ] 
   [ [ , ] MAXERRORS = max_errors ] 
   [ [ , ] ORDER ( { column [ ASC | DESC ] } [ ,...n ] ) ] 
   [ [ , ] ROWS_PER_BATCH = rows_per_batch ] 
   [ [ , ] ROWTERMINATOR = 'row_terminator' ] 
   [ [ , ] TABLOCK ] 
   [ [ , ] ERRORFILE = 'file_name' ] 
    )]
