Question

下午，

任何人都可以帮助我。我不是100％熟悉存储过程，但我一直在尝试使用下面的内容，但是对于我的生活无法弄清楚如何设置变量，我得到以下错误：

“过程或函数”SearchAllTables'需要参数'@SearchStr'，这是未提供的。“

ALTER PROC SearchAllTables
@SearchStr nvarchar(100)
AS
BEGIN
DECLARE @dml nvarchar(max) = N''        
IF OBJECT_ID('tempdb.dbo.#Results') IS NOT NULL DROP TABLE dbo.#Results
CREATE TABLE dbo.#Results
 ([tablename] nvarchar(100), 
  [ColumnName] nvarchar(100), 
  [Value] nvarchar(max))  
SELECT @dml += ' SELECT ''' + s.name + '.' + t.name + ''' AS [tablename], ''' + 
                c.name + ''' AS [ColumnName], CAST(' + QUOTENAME(c.name) + 
               ' AS nvarchar(max)) AS [Value] FROM ' + QUOTENAME(s.name) + '.' + QUOTENAME(t.name) +
               ' (NOLOCK) WHERE CAST(' + QUOTENAME(c.name) + ' AS nvarchar(max)) LIKE ' + '''%' + @SearchStr + '%'''
FROM sys.schemas s JOIN sys.tables t ON s.schema_id = t.schema_id
                   JOIN sys.columns c ON t.object_id = c.object_id
                   JOIN sys.types ty ON c.system_type_id = ty.system_type_id AND c .user_type_id = ty .user_type_id
WHERE t.is_ms_shipped = 0 AND ty.name NOT IN ('timestamp', 'image', 'sql_variant')

INSERT dbo.#Results
EXEC sp_executesql @dml

SELECT *
FROM dbo.#Results
END

提前致谢，非常感谢您的帮助！
