Question

DECLARE @H_TS MONEY
DECLARE @CLASS VARCHAR(50)='CLASS 04'   
DECLARE @TAB_NA VARCHAR(1000)='Classdata'
SET @SQL = 'SELECT @H_TS=SUM(CAST([HISTORY TOTAL$] AS MONEY)) FROM '+@TAB_NA+' WHERE SUBCLASS!=''TOTAL'' AND CLASS LIKE '+@CLASS+''
  EXECUTE SP_EXECUTESQL @SQL, N'@H_TS nvarchar(200) OUTPUT', @H_TS = @H_TS OUTPUT
PRINT @H_TS

我收到以下错误

Msg 102，Level 15，State 1，Line 1 '04'附近的语法不正确。

因为我的变量类包含空格有没有办法解决这个问题而不改变类值（不删除类中的空格）

Answer 1

我认为你只是缺少几个单引号：

SET @SQL = 'SELECT @H_TS=SUM(CAST([HISTORY TOTAL$] AS MONEY)) FROM '+@TAB_NA+' 
WHERE SUBCLASS!=''TOTAL'' AND CLASS LIKE ''' + @CLASS + '''' 

EXECUTE SP_EXECUTESQL @SQL, N'@H_TS nvarchar(200) OUTPUT', @H_TS = @H_TS OUTPUT

Answer 2

假设您正在尝试执行LIKE查询并需要您的％运算符，这可能就是您要查找的内容：

CREATE TABLE ClassData ([History Total$] int, SUBCLASS varchar(100), class varchar(100));

INSERT INTO ClassData VALUES (1, 'TOTAL', '1Class 04');
INSERT INTO ClassData VALUES (2, 'NOTTOTAL', '1Class 04 22');

DECLARE @H_TS MONEY
DECLARE @CLASS VARCHAR(50)='CLASS 04'   
DECLARE @TAB_NA VARCHAR(1000)='Classdata'
DECLARE @SQL NVARCHAR(MAX);

SET @SQL = 'SELECT @H_TS=SUM(CAST([HISTORY TOTAL$] AS MONEY)) FROM '+@TAB_NA+' WHERE SUBCLASS!=''TOTAL'' AND CLASS LIKE ''%' + @CLASS + '%''';

EXECUTE SP_EXECUTESQL @SQL, N'@H_TS nvarchar(200) OUTPUT', @H_TS = @H_TS OUTPUT
SELECT @H_TS

DROP TABLE ClassData

祝你好运。

我想从表中获取值按类动态过滤日期
