一、查询表
1、oracle
SELECT * FROM all_all_tables WHERE table_name = '表名';
2、sqlserver
select * from sysobjects where name='表名'
二、查询表字段
1、oracle
SELECT owner, table_name, column_name
FROM all_tab_columns WHERE column_name='字段名'
2、sqlserver
select A.[name] AS TABNAME,B.name AS COLNAME from sysobjects A,syscolumns B
where A.id =B.id AND B.name LIKE '%MAIN%'
三、查询表内容
1、oracle
SET SERVEROUTPUT ON SIZE 100000;
DECLARE
match_count INTEGER;
v_sql varchar2(2000);
BEGIN
FOR t IN (SELECT owner, table_name, column_name
FROM all_tab_columns
WHERE owner = 'xxxx' ---schema
and data_type LIKE '%VARCHAR%' ---datatype
AND table_name NOT LIKE '%copy%' )LOOP
match_count:=0;
v_sql:= 'SELECT COUNT(*) FROM ' || t.owner || '.' || t.table_name || ' WHERE '||t.column_name||' = :1';
--- dbms_output.put_line( t.owner || '.' || t.table_name) ;
EXECUTE IMMEDIATE v_sql INTO match_count USING '查询的内容';
IF match_count > 0 THEN
dbms_output.put_line( t.table_name ||' '||t.column_name||' '||match_count );
END IF;
END LOOP;
END;
2、sqlserver
create PROCEDURE [dbo].[SP_FindValueInDB]
(
@value VARCHAR(1024)
)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
DECLARE @sql VARCHAR(1024)
DECLARE @table VARCHAR(64)
DECLARE @column VARCHAR(64)
CREATE TABLE #t (
tablename VARCHAR(64),
columnname VARCHAR(64)
)
DECLARE TABLES CURSOR
FOR
SELECT o.name, c.name
FROM syscolumns c
INNER JOIN sysobjects o ON c.id = o.id
WHERE o.type = 'U' AND c.xtype IN (167, 175, 231, 239)
ORDER BY o.name, c.name
OPEN TABLES
FETCH NEXT FROM TABLES
INTO @table, @column
WHILE @@FETCH_STATUS = 0
BEGIN
SET @sql = 'IF EXISTS(SELECT NULL FROM [' + @table + '] '
SET @sql = @sql + 'WHERE RTRIM(LTRIM([' + @column + '])) LIKE ''%' + @value + '%'') '
SET @sql = @sql + 'INSERT INTO #t VALUES (''' + @table + ''', '''
SET @sql = @sql + @column + ''')'
EXEC(@sql)
FETCH NEXT FROM TABLES
INTO @table, @column
END
CLOSE TABLES
DEALLOCATE TABLES
SELECT *
FROM #t
DROP TABLE #t
End
exec SP_FindValueInDB '查找内容'
