检查SDE版本健康情况的常用SQL语句
检查各版本的状态树长度。
SELECT v.owner||'.'||v.name "VERSION NAME", COUNT(sl.lineage_id) "LINEAGE LENGTH"
FROM sde.states s, sde.state_lineages sl, sde.versions v
WHERE s.lineage_name = sl.lineage_name
AND sl.lineage_id <= s.state_id
AND v.state_id = s.state_id
GROUP BY v.owner, v.name, sl.lineage_name
ORDER BY "LINEAGE LENGTH";
长度越短查询性能越好。
检查某一图层的Default版本中未压缩到基础表的变化记录以及相对其他版本的占比
1、 首先获得图层的注册ID。
SELECT registration_id
FROM sde.table_registry
WHERE owner = 'ADMIN' AND table_name = 'PRIMARYOH';
2、 查询Default版本的状态ID和状态树名称。
VARIABLE lineage_id NUMBER;
BEGIN
SELECT state_id INTO :lineage_id FROM sde.versions WHERE owner = 'SDE' AND name = 'DEFAULT';
END;
VARIABLE lineage_name NUMBER;
BEGIN
SELECT lineage_name INTO :lineage_name FROM sde.states WHERE state_id = :lineage_id;
END;
3、 查询Default版本未压缩的增量表记录，假设图层的注册ID为67。
SELECT
(SELECT COUNT(*) FROM admin.a67
WHERE sde_state_id IN
(SELECT lineage_id FROM sde.state_lineages
WHERE lineage_name = :lineage_name AND lineage_id <= :lineage_id)) AS "NUMBER OF ROWS",
ROUND((SELECT COUNT(*) FROM admin.a67
WHERE sde_state_id IN
(SELECT lineage_id FROM sde.state_lineages
WHERE lineage_name = :lineage_name AND lineage_id <= :lineage_id))
/(SELECT COUNT(*) FROM admin.a67) * 100, 2) AS "PERCENTAGE OF ROWS",
(SELECT COUNT(*) FROM admin.a67) AS "TOTAL ROWS"
FROM dual;
4、 查询Default版本未压缩的删除表记录，假设图层的注册ID为67。
SELECT
(SELECT COUNT(*) FROM admin.d67
WHERE deleted_at IN
(SELECT lineage_id FROM sde.state_lineages
WHERE lineage_name = :lineage_name AND lineage_id <= :lineage_id)) AS "NUMBER OF ROWS",
ROUND((SELECT COUNT(*) FROM admin.d67
WHERE deleted_at IN
(SELECT lineage_id FROM sde.state_lineages
WHERE lineage_name = :lineage_name AND lineage_id <= :lineage_id))
/(SELECT COUNT(*) FROM admin.d67) * 100, 2) AS "PERCENTAGE OF ROWS",
(SELECT COUNT(*) FROM admin.d67) AS "TOTAL ROWS"
FROM dual;
Default版本的变化表记录越少越好，应该尽早提交阻碍Default版本压缩的版本，并压缩数据库。
