DECLARE @S NVARCHAR(1000)
DECLARE C CURSOR FOR --不区分大小写
    SELECT 'ALTER TABLE ['+B.NAME+'] ALTER COLUMN ['+A.NAME+'] '+ TYPE_NAME(A.XTYPE)+
        CASE WHEN TYPE_NAME(A.XTYPE) IN('TEXT','NTEXT') THEN '' ELSE
            QUOTENAME(A.LENGTH,'(')
        END +' COLLATE CHINESE_PRC_CI_AS' 
    FROM SYSCOLUMNS A
        JOIN SYSOBJECTS B ON A.ID=B.ID AND B.TYPE='U'
    WHERE TYPE_NAME(A.XTYPE) IN('VARCHAR','CHAR','NVARCHAR','NCHAR','TEXT','NTEXT')
OPEN C
FETCH C INTO @S
WHILE @@FETCH_STATUS=0
BEGIN
    EXEC(@S)
    FETCH C INTO @S
END
CLOSE C
DEALLOCATE C
