Therefore, when a BULK INSERT command is initiated by a login using SQL Server authentication, the connection to the data is made using the security context of the SQL Server process account (the account used by the SQL Server Database Engine service). To successfully read the source data ...
4. 使用BULK INSERT导入数据 使用BULK INSERT语句将数据从文件导入到临时表中。可以使用以下代码执行导入操作: stringbulkInsertQuery="BULK INSERT #TempTable FROM 'data.txt' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\\n')";using(SqlCommandcommand=newSqlCommand(bulkInsertQuery,connection)){command.E...
Therefore, when a BULK INSERT command is initiated by a login using SQL Server authentication, the connection to the data is made using the security context of the SQL Server process account (the account used by the SQL Server Database Engine service)....
下面介绍SQL Server支持的两种批量数据插入方法:Bulk和表值参数(Table-Valued Parameters)。 运行下面的脚本,建立测试数据库和表值参数。 --Create DataBase create database BulkTestDB; go use BulkTestDB; go --Create Table Create table BulkTestTable( Idint primary key, UserName nvarchar(32), Pwd varcha...
在SQL Server 中插入一条数据使用Insert语句,但是如果想要批量插入一堆数据的话,循环使用Insert不仅效率低,而且会导致SQL一系统性能问题。下面介绍SQL Server支持的两种批量数据插入方法:Bulk和表值参数(Table-Valued Parameters)。 运行下面的脚本,建立测试数据库和表值参数。
These optimizations are similar to those available with the BULK INSERT command. For more information, see Table Hints (Transact-SQL). Data Types When you insert rows, consider the following data type behavior: If a value is being loaded into columns with a char, varchar, or varbinary data ...
If a user uses a SQL Server login, the security profile of the SQL Server process account is used. A login using SQL Server authentication can't be authenticated outside of the Database Engine. Therefore, when a BULK INSERT command is initiated by a login using SQL Server authentication, ...
