ORACLE BIPUBLISHER SQL Query taking too long to execute - sql

Question

Following is the query
Select
pu.username,
ROLE.ROLE_NAME,
(
CASE
WHEN ((ROLE.ORG_ID IS NOT NULL) AND ROLE.ORG_ID=fabuv.BU_ID) THEN FABUV.BU_NAME
WHEN ((ROLE.LEDGER_ID IS NOT NULL) AND ROLE.LEDGER_ID=gl.LEDGER_ID) THEN GL.NAME
WHEN ((ROLE.BOOK_ID IS NOT NULL) AND ROLE.BOOK_ID=fbc.BOOK_CONTROL_ID) THEN FBC.BOOK_TYPE_NAME
WHEN ((ROLE.SET_ID IS NOT NULL) AND ROLE.SET_ID=fssv.SET_ID) THEN FSSV.SET_NAME
WHEN ((ROLE.INV_ORGANIZATION_ID IS NOT NULL) AND ROLE.INV_ORGANIZATION_ID=iop.ORGANIZATION_ID) THEN IOP.ORGANIZATION_CODE
WHEN ((ROLE.CST_ORGANIZATION_ID IS NOT NULL) AND ROLE.CST_ORGANIZATION_ID=ccov.COST_ORG_ID) THEN CCOV.COST_ORG_CODE
WHEN ((ROLE.ACCESS_SET_ID IS NOT NULL) AND ROLE.ACCESS_SET_ID=gas.ACCESS_SET_ID) THEN GAS.NAME
WHEN ((ROLE.CONTROL_BUDGET_ID IS NOT NULL) AND ROLE.CONTROL_BUDGET_ID=xcb.CONTROL_BUDGET_ID) THEN XCB.NAME
WHEN ((ROLE.INTERCO_ORG_ID IS NOT NULL) AND ROLE.INTERCO_ORG_ID=fio.INTERCO_ORG_ID) THEN FIO.INTERCO_ORG_NAME
ELSE 'NOT_APPLICABLE'
END
) "Security_Context_Value"
from
fusion.per_users pu,
fusion.FA_BOOK_CONTROLS FBC,
fusion.FUN_ALL_BUSINESS_UNITS_V FABUV,
fusion.XCC_CONTROL_BUDGETS XCB,
fusion.CST_COST_ORGS_V CCOV,
fusion.gl_access_sets GAS,
fusion.FUN_INTERCO_ORGANIZATIONS FIO,
fusion.INV_ORG_PARAMETERS iOP,
fusion.GL_LEDGERS GL,
fusion.RCS_MFG_PARAMETERS RMP,
fusion.FUN_USER_ROLE_DATA_ASGNMNTS ROLE,
fusion.FND_SETID_SETS_VL FSSV
where
1=1
and pu.USERNAME=:Username
AND ROLE.ORG_ID != NULL
OR ROLE.LEDGER_ID != NULL
OR ROLE.BOOK_ID != NULL
OR ROLE.SET_ID != NULL
OR ROLE.INV_ORGANIZATION_ID != NULL
OR ROLE.CST_ORGANIZATION_ID != NULL
OR ROLE.ACCESS_SET_ID != NULL
OR ROLE.CONTROL_BUDGET_ID != NULL
OR ROLE.INTERCO_ORG_ID != NULL
And pu.USER_GUID=role.USER_GUID
It is the query required to extract roles assigned to users with Security_Context and Value.
I have tried different combinations of using IS NOT NULL in place of '!=' but it also didnt help, again Username is not taken into consideration when if it run.

I think what you're after is something like:
SELECT pu.username,
role.role_name,
CASE WHEN ROLE.ORG_ID IS NOT NULL THEN FABUV.BU_NAME
WHEN ROLE.LEDGER_ID IS NOT NULL THEN GL.NAME
WHEN ROLE.BOOK_ID IS NOT NULL THEN FBC.BOOK_TYPE_NAME
WHEN ROLE.SET_ID IS NOT NULL THEN FSSV.SET_NAME
WHEN ROLE.INV_ORGANIZATION_ID IS NOT NULL THEN IOP.ORGANIZATION_CODE
WHEN ROLE.CST_ORGANIZATION_ID IS NOT NULL THEN CCOV.COST_ORG_CODE
WHEN ROLE.ACCESS_SET_ID IS NOT NULL THEN GAS.NAME
WHEN ROLE.CONTROL_BUDGET_ID IS NOT NULL THEN XCB.NAME
WHEN ROLE.INTERCO_ORG_ID IS NOT NULL THEN FIO.INTERCO_ORG_NAME
ELSE 'NOT_APPLICABLE'
END "Security_Context_Value"
FROM fusion.per_users pu
INNER JOIN fusion.fun_user_role_data_asgnmnts role ON pu.user_guid = role.user_guid
LEFT OUTER JOIN fusion.fun_all_business_units_v fabuv ON role.org_id = fabuv.bu_id
LEFT OUTER JOIN fusion.gl_ledgers gl ON role.ledger_id = gl.ledger_id
LEFT OUTER JOIN fusion.fa_book_controls fbc ON role.book_id=fbc.book_control_id
LEFT OUTER JOIN fusion.fnd_setid_sets_vl fssv ON role.SET_ID=fssv.SET_ID

LEFT OUTER JOIN fusion.xcc_control_budgets xcb ON role.control_budget_id=xcb.control_budget_id
LEFT OUTER JOIN fusion.fun_interco_organizations fio ON role.interco_org_id=fio.interco_org_id
WHERE pu.username = :username
AND COALESCE(role.org_id,
role.ledger_id,
role.book_id,
role.set_id,
role.inv_organization_id,
role.cst_organization_id,
role.access_set_id,
role.control_budget_id,
role.interco_org_id) IS NOT NULL;
Note the use of the ANSI join syntax, which forces you to add in join conditions (unless you explicitly request a cross join).
Your original query was doing a cross join between your fabuv, gl, fbc, etc tables, meaning each row in fabuv was being joined to all rows in gl, and each of the resultant rows was being joined to every row in the fbc table and so on... that's a lot of rows - e.g. if there are 100 rows in each of the fabuv, gl, fbc, etc tables, you're going to end up with 100 x 100 x 100 x ... which ends up being way too many rows.
I've take a guess as to what the join conditions should be, based on your case statement - n.b. the rmp table wasn't being referenced at all, so I've excluded it from the from clause.
I also used the COALESCE function to simplify your where clause - this function returns the first not-null value.
