SQL Server 变量定义

Posted 2020-11-22 筱筱的春天

  declare @id int
declare @name char(10) --注意：char（10）为10位，要是位数小了会让数据出错
set @id=1
set @name=\'sssss\'
select @id valu,@name nam

 

 

 

 

下面是我同事的一个情况， 要把一堆字符里面的表都给粘出来， 里面用到了变量的定义

declare @str varchar(max) =\'jgguf${wlsld2}  dhslsla${wlsld3}dhsl

sla${wlsld5}dh

dlsla${wlsgsld6} dlsla${wslsld7} dsgdlsla \'

 

select value from string_split(replace(@str, \' \', \'#\'), \'$\')

--{wlsld2}dhslsla

 

select substring(k.value2, 1, k.len1) as value3 from

(select substring(value, 2, charindex(\'}\', value)) as value2,

              len(substring(value, 2, charindex(\'}\', value))) - 2 as len1 from string_split(replace(@str, \' \', \'#\'), \'$\')

) as k

where k.len1 > 0

go
