如果有人想使用powershell导入csv

## Install module if not installed, this is a one time install.
Install-Module SqlServer

## Input SQL Server Variables and CSV path
$csvPath = "D:\Orders.csv"
$csvDelimiter = ","
$serverName = "DESKTOP-DOG5T0Q\SQLEXPRESS"
$databaseName = "OrderDetails"
$tableSchema = "dbo"
$tableName = "Orders"

## Truncate Table
Invoke-Sqlcmd -ServerInstance $serverName -Database $databaseName -Query "TRUNCATE TABLE $tableSchema.$tableName"

## Import CSV into SQL
Import-Csv -Path $csvPath -header "Id","Country","Price","OrderQuantity" -Delimiter $csvDelimiter | Write-SqlTableData -ServerInstance $serverName -DatabaseName $databaseName -SchemaName $tableSchema -TableName $tableName -Force

导入csv到SQL server(使用SSMS查询或不查询)

2)如果客户端从excel中创建了csv，那么有数据 逗号被括在"…(双引号)[如下所示 那么导入如何处理这个问题呢?

你应该使用FORMAT = 'CSV'， FIELDQUOTE = '"'选项:

BULK INSERT SchoolsTemp
FROM 'C:\CSVData\Schools.csv'
WITH
(
    FORMAT = 'CSV', 
    FIELDQUOTE = '"',
    FIRSTROW = 2,
    FIELDTERMINATOR = ',',  --CSV field delimiter
    ROWTERMINATOR = '\n',   --Use to shift the control to next row
    TABLOCK
)

All of the answers here work great if your data is "clean" (no data constraint violations, etc.) and you have access to putting the file on the server. Some of the answers provided here stop at the first error (PK violation, data-loss error, etc.) and give you one error at a time if using SSMS's built in Import Task. If you want to gather all errors at once (in case you want to tell the person that gave you the .csv file to clean up their data), I recommend the following as an answer. This answer also gives you complete flexibility as you are "writing" the SQL yourself.

注意:我将假设您运行的是Windows操作系统，并且能够访问Excel和SSMS。如果没有，我相信你可以调整这个答案来满足你的需求。

Using Excel, open your .csv file. In an empty column you will write a formula that will build individual INSERTstatements like =CONCATENATE("INSERT INTO dbo.MyTable (FirstName, LastName) VALUES ('", A1, "', '", B1,"')", CHAR(10), "GO") where A1 is a cell that has the first name data and A2 has the last name data for example. CHAR(10) adds a newline character to the final result and GO will allow us to run this INSERT and continue to the next even if there are any errors. Highlight the cell with your =CONCATENATION() formula Shift + End to highlight the same column in the rest of your rows In the ribbon > Home > Editing > Fill > Click Down This applies the formula all the way down the sheet so you don't have to copy-paste, drag, etc. down potentially thousands of rows by hand Ctrl + C to copy the formulated SQL INSERT statements Paste into SSMS You will notice Excel, probably unexpectedly, added double quotes around each of your INSERT and GO commands. This is a "feature" (?) of copying multi-line values out of Excel. You can simply find and replace "INSERT and GO" with INSERT and GO respectively to clean that up. Finally you are ready to run your import process After the process completes, check the Messages window for any errors. You can select all the content (Ctrl + A) and copy into Excel and use a column filter to remove any successful messages and you are left with any and all the errors.

这个过程肯定会比这里的其他答案花费更长的时间，但是如果您的数据是“脏的”并且充满SQL违规，您至少可以一次性收集所有错误并将它们发送给提供数据的人(如果您的场景是这样的话)。

也许不是你想要的，但另一种选择是为notepad++使用CSV Lint插件

该插件可以事先验证csv数据，这意味着检查坏数据，如缺少引号、不正确的十进制分隔符、日期时间格式错误等。而不是BULK INSERT，它可以将csv文件转换为SQL插入脚本。

SQL脚本将为每1000条记录的csv行包含INSERT语句，并调整任何datetime和十进制值。该插件自动检测csv中的数据类型，它将包括一个CREATE TABLE部分，其中包含每个列的正确数据类型。

如上所述，您需要添加FORMAT和FIELDQUOTE选项来批量将. csv数据插入SQL Server。对于你的case, SQL语句是这样的:

BULK INSERT SchoolsTemp
FROM 'C:\CSVData\Schools.csv'
WITH
(
    FORMAT = 'CSV', 
    FIELDQUOTE = '""',
    FIRSTROW = 2,
    FIELDTERMINATOR = ',',
    ROWTERMINATOR = '\n',
    TABLOCK
)

虽然SSMS中的BULK INSERT非常适合一次性导入作业，但根据您的用例，您可能需要SSMS内部或使用第三方的其他选项。下面是一个详细的指南，描述了将CSV文件导入SQL Server的各种选项，包括自动化(我的意思是计划)过程和为CSV位置指定FTP或文件存储的方法。

解决数据中逗号问题的最好、最快和最简单的方法是在将Windows的列表分隔符设置为逗号以外的内容(如管道)后，使用Excel保存一个逗号分隔的文件。这将为您生成一个管道(或其他)分离文件，然后您可以导入该文件。这里描述了这一点。
