Question

在我的存储过程中，我定义了以下部分：

SET @table = 'table_name'
SET @column = 'table_column'
WHILE (SELECT COUNT(1) FROM @table WHERE @column LIKE @filter) > 0
BEGIN
  SELECT TOP (1) @email = @column FROM @table WHERE @column LIKE @filter
  EXEC sp_OAMethod @object, 'Replace', @result OUT, @email, @employeeNewEmail
  UPDATE TOP (1) @table SET @column = @result WHERE @column LIKE @filter
END

这需要在许多表上完成，所以我想将WHILE语句包装到动态sql查询中

SET @query =
'WHILE (SELECT COUNT(1) FROM '+@table+' WHERE '+@column+' LIKE '+@filter+') > 0
BEGIN
  SELECT TOP (1) '+@email+' = '+@column+' FROM '+@table+' WHERE '+@column+' LIKE '+@filter+'
  EXEC sp_OAMethod '+@object+', ''Replace'', '+@result+' OUT, '+@email+', '+@employeeNewEmail+'
  UPDATE TOP (1) '+@table+' SET '+@column+' = '+@result+' WHERE '+@column+' LIKE '+@filter+'
END'

然后简单地

SET @table = 'table_name'
SET @column = 'table_column'
EXEC (@query)

不幸的是，这不起作用，我总是收到错误：

将varchar值'，'转换为数据类型int。
时转换失败

我错过了什么？

SET @table = 'table_name'
SET @column = 'table_column'

WHILE (SELECT COUNT(1) FROM '+@table+' WHERE '+@column+' LIKE '+@filter+') > 0
BEGIN
    SET @query ='SELECT TOP (1) '+@email+' = '+@column+' FROM '+@table+' WHERE '+@column+' LIKE '+@filter+'
    EXEC sp_OAMethod '+@object+', ''Replace'', '+@result+' OUT, '+@email+', '+@employeeNewEmail+'
    UPDATE TOP (1) '+@table+' SET '+@column+' = '+@result+' WHERE '+@column+' LIKE '+@filter+''
    exec(@query)
END

如何在EXEC中执行sp_OAMethod（@sql）
