我想从多个表格中删除有条件的内容。
DELETE
FROM table_1
WHERE lst_mod_ymdt = 2011-01-01
The problem is that, the number of table is 400, from table_1 to table_400. Can I apply the query to all the tables in a single query?

如果你重新使用2005年服务器,然后你可以尝试像这样的东西(其他版本和RDMS也有类似的办法这样做):
DECLARE @sql VARCHAR(MAX)
SET @sql = (SELECT DELETE FROM [ + REPLACE(Name, , ) + ] WHERE lst_mod_ymdt = + @lst_mod_ymdt + ; FROM sys.tables WHERE Name LIKE table_% FOR XML PATH( ))
--PRINT @sql;
EXEC ( @sql );
和总是有活力的缩略语一样,记住要躲避<条码>>。
如果你说的是表341,其中tt有lst_mod_ymdt
栏,则这很可能被搁置。
