我有一个如下所示的批处理文件:
ECHO OFF
set /P sn= Enter Customer ID:
sqlcmd -S C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\Trial -i
deletesql.sql -o delete.txt -v delete=%sn%
数据库名称为Trial
我的 deletesql.sql 文件搜索数据库并删除用户输入的特定ID的每条记录。例如,如果用户键入 1 ,代码应在数据库中搜索包含 CustomerID 作为列的每个表,并将 1 作为值
这是我的deletesql.sql代码:
declare @columnName nvarchar(255)
declare @intValue int
set @columnName = 'CustomerId' --COLUMN NAME WHERE VALUE IS LOCATED
set @intValue = 2 --VALUE TO BE DELETED
declare @DeleteValue varchar(10)
set @DeleteValue = convert(varchar(10), @intValue)
declare @sql nvarchar(max) = ''
select @sql = @sql + 'delete ' + object_name(c.object_id) + ' where ' + @columnName + ' = ' + @DeleteValue + ';'
from sys.columns c
where c.name = @columnName
select @sql
exec sp_executesql @sql
代码完全由它自己运行,但我试图让它与.bat文件中的用户输入一起工作正如你所看到的,我硬编码了列名和值我的.sql文件。
如何更改我的.sql和.bat文件,以便我的.sql文件取决于我的.bat文件输入(列名和值)
我的bat文件中还有3个错误:
Sqlcmd: Error: Microsoft SQL Server Native Client 11.0 : SQL Server Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF]. .
Sqlcmd: Error: Microsoft SQL Server Native Client 11.0 : Login timeout expired.
