问题描述
我在prepareStatment中使用以下查询。之前我在PL / sql过程中使用了相同的查询。
INSERT INTO dynamicentitygtt
(entity_type,entity_id,entity_code,synonyms,action)
WITH data_view AS
( -- ITEM table
SELECT 'ITEMENTITY' entity_type,-- This separates inserted values
item_id data_id,item_name data_name,item_desc data_desc,creation_date
FROM itemde
UNION ALL
-- ORG table
SELECT 'ORGENTITY' entity_type,-- This separates inserted values
org_id,org_name,org_desc,creation_date
FROM orgde
UNION ALL
-- Feature table
SELECT 'FEATUREENTITY' entity_type,-- This separates inserted values
FEATURE_id data_id,FEATURE_NAME data_name,FEATURE_DESC data_desc,CREATION_DATE
FROM FEATURESDE
)
SELECT upper(t.entity_type),t.data_id,t.data_name,t.data_desc,CASE UPPER(p_update_mode)
WHEN 'INCREMENTAL' THEN
CASE
WHEN t.creation_date > b.last_update_date THEN
'modify'
WHEN t.creation_date < b.last_update_date THEN
'add'
END
WHEN 'FULL' THEN
'add'
END action
FROM data_view t
LEFT JOIN ODA_REFRESH_DETAILS b
ON b.entity_type = t.entity_type
AND lower(p_update_mode )='INCREMENTAL'
WHERE (upper(p_entity_type) = t.entity_type OR p_entity_type IS NULL)
AND (UPPER(p_update_mode) = 'FULL'
OR (UPPER(p_update_mode) = 'INCREMENTAL' AND b.entity_type IS NOT NULL)
);
我从上游收到2个变量p_entity_type和p_update_mode。因此我正在使用?设置这些值。
我的代码如下。无论这些变量放在哪里，我都将?放在后面，然后设置相应的值。
public int insertDataToGTT(String p_entity_type,String p_update_mode) throws Exception
{
String sql= "INSERT INTO dynamicentitygtt
(entity_type,action)
WITH data_view AS( -- ITEM table
SELECT 'ITEMENTITY' entity_type,-- This separates inserted values
item_id data_id,creation_date
FROM itemde
UNION ALL
-- ORG table
SELECT 'ORGENTITY' entity_type,-- This separates inserted values
org_id,creation_date
FROM orgde
UNION ALL
-- Feature table
SELECT 'FEATUREENTITY' entity_type,-- This separates inserted values
FEATURE_id data_id,CREATION_DATE
FROM FEATURESDE
)
SELECT upper(t.entity_type),CASE UPPER(?) //p_update_mode
WHEN 'INCREMENTAL' THEN
CASE
WHEN t.creation_date > b.last_update_date THEN
'modify'
WHEN t.creation_date < b.last_update_date THEN
'add'
END
WHEN 'FULL' THEN
'add'
END action
FROM data_view t
LEFT JOIN ODA_REFRESH_DETAILS b
ON b.entity_type = t.entity_type
AND lower(?)='INCREMENTAL' //p_update_mode
WHERE (upper(?) = t.entity_type OR ? IS NULL) //p_entity_type(both places)
AND (UPPER(?) = 'FULL' //p_update_mode
OR (UPPER(?) = 'INCREMENTAL' AND b.entity_type IS NOT NULL) //p_update_mode
) "
PreparedStatement statement= connection.prepareStatement(sql);
statement.setString(1,p_update_mode);
statement.setString(2,p_update_mode);
statement.setString(3,p_update_mode);
statement.setString(4,p_entity_type);
statement.setString(5,p_entity_type);
statement.setString(6,p_update_mode);
int x=statement.executeUpdate();
System.out.println("Number of rows inserted: "+x);
return x;
}
这给了我以下例外。我检查了我设置正确的参数。实际上，我在多个地方使用相同的值。反正有什么更好的办法吗？
