cursor loop and continue statement : unexpected behaviour

由 ≡放荡痞女 提交于 2019-12-07 04:10:09
问题 I might be overlooking something due to deadline stress. But this behaviour amazes me. It looks as if the cursor caches 100 rows and the continue statement flushes the cache and begins with the first record of a new cache fetch. I narrowed it down to the following script: drop table test1; create table test1 (test1_id NUMBER); begin for i in 1..300 loop insert into test1 values (i); end loop; end; / declare cursor c_test1 is select * from test1; begin for c in c_test1 loop if mod(c.test1_id

Fetch and bulk collect from a REF CURSOR returned by a procedure

由 两盒软妹~` 提交于 2019-12-07 00:17:25
I have a stored procedure that has a SYS_REFCURSOR as an OUT parameter. The signature is, for example, as follows: PROCEDURE myProc(p_someID IN INTEGER, p_cursor OUT SYS_REFCURSOR); I call this procedure from a function, where I have to copy a column named clientID from the p_cursor to a scalar nested table. I am doing as follows: CREATE OR REPLACE FUNCTION myFunction RETURN sys_refcursor IS someID INTEGER := 1234; myCursor SYS_REFCURSOR; TYPE t_clientID_nt IS TABLE OF NUMBER(16,0); clientID_nt t_clientID_nt; otherID SYS_REFCURSOR; BEGIN myProc (someID, myCursor); FOR i IN myCursor LOOP

Which I later found out that I should have given the path to java.exe inside oracle folder. Now every time I run it doesn't ask me for java.exe

increment function in plsql

由 末鹿安然 提交于 2019-12-06 18:31:42
问题 In most programming languages you have a fast way to write an increment for a variable like the following examples: inc(variableName); variableName++; variableName += 1; Which ways are there in Oracle Pl/Sql to do this instead of using the following: variableName := variableName + 1; 回答1: The operators are listed in the documentation. There is no equivalent of ++ or += . I'm afraid you have to do it the long way. You could write your own inc() function but that would probably make your code
