1. Oracle获取表sql
1.1 有DBA权限获取方式
select distinct TABLE_NAME from dba_tables where OWNER ='库名' and owner NOT IN ('SYS','SYSTEM','OUTLN','XDB','WMSYS','CTXSYS','MDSYS')
1.2 普通权限获取方式
select distinct TABLE_NAME from all_tables where OWNER ='库名' and owner NOT IN ('SYS','SYSTEM','OUTLN','XDB','WMSYS','CTXSYS','MDSYS')
2. Oracle获取表字段sql
2.1 有DBA权限获取方式
SELECT UPPER(T.TABLE_NAME),NVL(cc.comments, ''),C.COLUMN_NAME,CC.COMMENTS,C.DATA_TYPE,C.DATA_LENGTH,C.DATA_PRECISION,C.DATA_SCALE ,NULLABLE,CASE WHEN PK.CONSTRAINT_TYPE = 'P' THEN 'y' ELSE 'n' END FROM DBA_tables T JOIN DBA_TAB_COLUMNS C ON T.TABLE_NAME = C.TABLE_NAME AND T.OWNER = C.OWNER LEFT JOIN DBA_COL_COMMENTS CC ON C.OWNER = CC.OWNER AND C.TABLE_NAME = CC.TABLE_NAME AND C.COLUMN_NAME = CC.COLUMN_NAME LEFT JOIN (SELECT CONS.TABLE_NAME, CONS.OWNER, COLS.COLUMN_NAME, CONS.CONSTRAINT_TYPE FROM DBA_CONSTRAINTS CONS JOIN DBA_CONS_COLUMNS COLS ON CONS.CONSTRAINT_NAME = COLS.CONSTRAINT_NAME WHERE CONS.CONSTRAINT_TYPE = 'P' ) PK ON C.OWNER = PK.OWNER AND C.TABLE_NAME = PK.TABLE_NAME AND C.COLUMN_NAME = PK.COLUMN_NAME where UPPER(T.TABLE_NAME) in ( 逗号分隔的表名 ) and t.OWNER NOT IN ('SYS', 'SYSTEM', 'OUTLN', 'XDB', 'WMSYS', 'CTXSYS', 'MDSYS') ORDER BY T.TABLE_NAME, C.COLUMN_ID
2.2 普通权限获取方式
SELECT UPPER(T.TABLE_NAME),NVL(cc.comments, ''),C.COLUMN_NAME,CC.COMMENTS,C.DATA_TYPE,C.DATA_LENGTH,C.DATA_PRECISION,C.DATA_SCALE ,NULLABLE,CASE WHEN PK.CONSTRAINT_TYPE = 'P' THEN 'y' ELSE 'n' END FROM all_tables T JOIN ALL_TAB_COLUMNS C ON T.TABLE_NAME = C.TABLE_NAME AND T.OWNER = C.OWNER LEFT JOIN ALL_COL_COMMENTS CC ON C.OWNER = CC.OWNER AND C.TABLE_NAME = CC.TABLE_NAME AND C.COLUMN_NAME = CC.COLUMN_NAME LEFT JOIN (SELECT CONS.TABLE_NAME, CONS.OWNER, COLS.COLUMN_NAME, CONS.CONSTRAINT_TYPE FROM ALL_CONSTRAINTS CONS JOIN ALL_CONS_COLUMNS COLS ON CONS.CONSTRAINT_NAME = COLS.CONSTRAINT_NAME WHERE CONS.CONSTRAINT_TYPE = 'P' ) PK ON C.OWNER = PK.OWNER AND C.TABLE_NAME = PK.TABLE_NAME AND C.COLUMN_NAME = PK.COLUMN_NAME where UPPER(T.TABLE_NAME) in ( 逗号分隔的表名 ) and t.OWNER NOT IN ('SYS', 'SYSTEM', 'OUTLN', 'XDB', 'WMSYS', 'CTXSYS', 'MDSYS') ORDER BY T.TABLE_NAME, C.COLUMN_ID
3. Oracle获取视图sql
3.1 有DBA权限获取方式
select distinct view_name from all_views where owner not in ('SYS','SYSTEM','OUTLN','XDB','WMSYS','CTXSYS','MDSYS') and OWNER ='库名';
3.2 普通权限获取方式
select distinct view_name from all_views where owner not in ('SYS','SYSTEM','OUTLN','XDB','WMSYS','CTXSYS','MDSYS') and OWNER ='库名';
4. Oracle获取视图字段sql
4.1 有DBA权限获取方式
SELECT c.table_name AS view_name, NVL ( cm.comments, '' ) AS cmt, c.column_name, cm.comments, c.data_type, c.data_length, c.data_precision, c.data_scale, c.nullable, 'n' AS is_primary_key FROM dba_tab_columns c LEFT JOIN dba_col_comments cm ON c.OWNER = cm.OWNER AND c.table_name = cm.table_name AND c.column_name = cm.column_name WHERE c.OWNER = '库名' AND c.table_name IN ( 逗号分隔的表名 ) ORDER BY c.table_name,c.column_id
4.2 普通权限获取方式
SELECT c.table_name AS view_name, NVL ( cm.comments, '' ) AS cmt, c.column_name, cm.comments, c.data_type, c.data_length, c.data_precision, c.data_scale, c.nullable, 'n' AS is_primary_key FROM all_tab_columns c LEFT JOIN all_col_comments cm ON c.OWNER = cm.OWNER AND c.table_name = cm.table_name AND c.column_name = cm.column_name WHERE c.OWNER = '库名' AND c.table_name IN ( 逗号分隔的表名 ) ORDER BY c.table_name,c.column_id
