问题 I have a procedure that takes an input of 2 Associative arrays and after some basic count checks, does a FORALL statement to insert the data into a table. Here is the procedure: PROCEDURE INSERT_RECS(P_PROD_TYP IN prod_type, P_PROD_ADD_PK IN prod_pk_type) IS uniq_key EXCEPTION; PRAGMA EXCEPTION_INIT(uniq_key, -00001); loc_cnt NUMBER; BEGIN IF P_PROD_TYP.COUNT = P_PROD_ADD_PK.COUNT THEN FORALL i IN P_PROD_TYP.FIRST .. P_PROD_TYP.LAST INSERT INTO product_table ( pk, id, created_by, created_on,

问题 Problem I'm trying to refactor a low-performing MERGE statement to an UPDATE statement in Oracle 12.1.0.2.0. The MERGE statement looks like this: MERGE INTO t USING ( SELECT t.rowid rid, u.account_no_new FROM t, u, v WHERE t.account_no = u.account_no_old AND t.contract_id = v.contract_id AND v.tenant_id = u.tenant_id ) s ON (t.rowid = s.rid) WHEN MATCHED THEN UPDATE SET t.account_no = s.account_no_new It is mostly low performing because there are two expensive accesses to the large (100M rows

问题 This question already has an answer here : Oracle get checksum value for a data chunk defined by a select clause (1 answer) Closed 2 years ago . We need to be able to compute table hashes for an external environment and compare it to pre-computed hash from an internal environment. The use of this is to ensure that data in the external environment is not tampered by a "rogue" database administrator. Users insist this feature . Currently, we do this by computing the individual hashes of each

问题 Does Oracle let me include columns to index (like SQL Server INCLUDE clause in CREATE INDEX ) ? Thanks. 回答1: No. An index in Oracle either includes the column in the index itself or it doesn't. Depending on the problem you are trying to solve, however, an index-organized table may be the appropriate analogue in Oracle. 回答2: CREATE TABLE test ( a VARCHAR2(400 char) NOT NULL PRIMARY KEY, b NUMBER(33) NOT NULL ); CREATE TABLE test_2 ( a VARCHAR2(400 char) NOT NULL, b NUMBER(33) NOT NULL );
