如何在查询中插入单引号？查询中的单引号
例
select *, 'INSERT INTO San_Endereco (Endereco_Id, Logradouro_Id, Bairro_Id, CEP, Logradouro, Livre) VALUES
(' + CAST(Endereco_Id as varchar) + ','
+ CAST(Logradouro_Id as varchar) + ','
+ CAST(Bairro_Id as varchar) + ','
+ CAST (CEP as varchar) + ','
+ CAST(Logradouro as varchar) + ','
+ CAST(Livre as varchar) + ')' as teste
FROM San_Endereco
每个CAST我需要把单引号之前。我怎样才能做到这一点 ？
使用两个单引号：''
select *, 'INSERT INTO San_Endereco (Endereco_Id, Logradouro_Id, Bairro_Id, CEP, Logradouro, Livre) VALUES
(''' + CAST(Endereco_Id as varchar) + ''','''
+ CAST(Logradouro_Id as varchar) + ''','''
+ CAST(Bairro_Id as varchar) + ''','''
+ CAST (CEP as varchar) + ''','''
+ CAST(Logradouro as varchar) + ''','''
+ CAST(Livre as varchar) + ''')''' as teste
FROM San_Endereco
select *, 'INSERT INTO San_Endereco (Endereco_Id, Logradouro_Id, Bairro_Id, CEP, Logradouro, Livre) VALUES
(''' + CAST(Endereco_Id as varchar) + ''','
+ ....
使用双单引号''
如果一个单引号包含在实际数据要插入，命令经常被损坏。为了解决这个问题，只需用两个引号替换任何单引号（不是双引号字符，而是两个单引号字符）。

你必须在字符串使用'两次：
declare @var varchar(100)
select @var = 'txt'
select ' '[email protected]+' ' -- without single quote
select ''''[email protected]+'''' -- with single quote
declare @var varchar(100)
select @var = 'txt'
select char(39)[email protected]+char(39) -- with single quote
