问题 Lets say I have a table and a procedure that accepts one argument of the tables rowtype: CREATE TABLE t (a NUMBER, b NUMBER); CREATE PROCEDURE p (x t%ROWTYPE) IS BEGIN NULL; END; Can I call that procedure using a rowtype literal, that is without explicitly creating a rowtype variable (or at least not explicitly listing and assigning every field of it)? The two following approaches both generate the below error: p(1, 2); p((1, 2)); PLS-00306: wrong number or types of arguments in call to 'P'

plpgsql function that returns multiple columns gets called multiple times

阅读更多关于 plpgsql function that returns multiple columns gets called multiple times

问题 I'm running PostgreSQL 9.2.1 and have a plpgsql function that returns 3 columns. It's called like this (simplified): SELECT (my_function(b.input)).*, a.other, b.columns FROM table_a a JOIN table_b b ON a.id = b.id WHERE ... The function prints out a WARNING message and I was surprised to find it printed 3 times. It looks like the function gets called 3 times - presumably once for each column. This can't be good for performance! How can I make sure it's called only once? It's already marked

How to pass an entire row (in SQL, not PL/SQL) to a stored function?

阅读更多关于 How to pass an entire row (in SQL, not PL/SQL) to a stored function?

问题 I am having the following (pretty simple) problem. I would like to write an (Oracle) SQL query, roughly like the following: SELECT count(*), MyFunc(MyTable.*) FROM MyTable GROUP BY MyFunc(MyTable.*) Within PL/SQL, one can use a RECORD type (and/or %ROWTYPE), but to my knowledge, these tools are not available within SQL. The function expects the complete row, however. What can I do to pass the entire row to the stored function? Thanks! 回答1: Don't think you can. Either create the function with

How to use %ROWTYPE when inserting into Oracle table with identity column?

阅读更多关于 How to use %ROWTYPE when inserting into Oracle table with identity column?

问题 I have an Oracle 12c database with a table containing an identity column: CREATE TABLE foo ( id NUMBER GENERATED ALWAYS AS IDENTITY PRIMARY KEY, bar NUMBER ) Now I want to insert into the table using PL/SQL. Since in practice the table has many columns, I use %ROWTYPE : DECLARE x foo%ROWTYPE; BEGIN x.bar := 3; INSERT INTO foo VALUES x; END; However, it give me this error: ORA-32795: cannot insert into a generated always identity column ORA-06512: at line 5 Since it is very good for code

问题 Is it possible to create a rowtype for a table name which is passed as a parameter to a Stored-Procedure and also how do i know the columns to address them in the DBMS_OUUTPUT.PUT_LINE() statement. The end user can give any user name(schema) and table name I want to do something as below but it does not work.

问题 I've got an Oracle procedure, that I want to be somehow generic. I would like to: pass a table name as a varchar parameter use EXECUTE IMMEDIATE to dynamically select data store the result in the %ROWTYPE variable of passed type The third point seems to be a problem. I'm not sure if i can create a type dynamically inside the procedure body. It would be great to have something like this: procedure CHANGE_GENERIC(tableName in VARCHAR2, someOldVal in integer, someNewVal in integer) is v_sql

I have one table called event , and created another global temp table tmp_event with the same columns and definition with event. Is it possible to insert records in event to tmp_event using this ? DECLARE v_record event%rowtype; BEGIN Insert into tmp_event values v_record; END; There are too many columns in event table, I want to try this because I don't want to list all the columns. Forget to mention: I will use this in the trigger, can this v_record be the object :new after insert on EVENT table ? To insert one row- DECLARE v_record event%rowtype; BEGIN SELECT * INTO v_record from event

how to declare %ROWTYPE of a variable that is a weakly typed SYS_REFCURSOR?

阅读更多关于 how to declare %ROWTYPE of a variable that is a weakly typed SYS_REFCURSOR?

W.r.t code below I can not declare the type of fetch-into-variable as the underlying table's %ROWTYPE because the SYS_REFCURSOR is on a select that joins two tables and also selects a few functions called on the attributes of the underlying two tables; i.e I can't declare as L_RECORD T%ROWTYPE --- DECLARE P_RS SYS_REFCURSOR; L_RECORD P_RS%ROWTYPE; BEGIN CAPITALEXTRACT( P_RS => P_RS ); OPEN P_RS; LOOP BEGIN FETCH P_RS INTO L_RECORD; EXIT WHEN P_RS%NOTFOUND; ... EXCEPTION WHEN OTHERS THEN ... END; END LOOP; CLOSE P_RS; END; -------- CREATE or REPLACE PROCEDURE CAPITALEXTRACT ( p_rs OUT SYS
