查询中的单引号

Question

如何在查询中插入单引号？

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

在每个CAST我需要之前把单引号.我怎样才能做到这一点 ？

Answer 1

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
