as a dataset using the table () keyword. The following is a simple example: createtabletb1(knumber,vvarchar2(10)); insertintotb1(k,v)values(100,'aaa'); insertintotb1(k,v)values(200,'bbb'); insertintotb1(k,v)values(200,'ccc'); select*fromtb1; createtyperow_type1asobject(knumber,vvarchar2(10)); createtypetable_type1astableofrow_type1; createorreplacefunctionfun1returntable_type1pipelinedas vrow_type1; begin formyrowin(selectk,vfromtb1)loop v:=r

The methods defined by the oracle function return type as record may not be available to everyone. The following describes an oracle function return type as record-defined instance for your reference. CREATE OR REPLACE Package pkg_test /* Define the ref cursor type The return type is not added.

Replace (, [,]) C1, c2, and c3 are strings. The function uses c3 instead of c2 that appears in c1 and returns the result. Select replace (''uptown '', ''up'', ''down '') from dualreplacedowntown Stbstr (, [,]) C1 is a string, where I and j are integers. Starting from the I-bit of c1, a substring with the

In Oracle, The SYS_CONNECT_BY_PATH function is a very important function. The following describes an example of using the SYS_CONNECT_BY_PATH function. The example is as follows: Create table test (a varchar2 (10), B varchar2 (10 )); Insert into test (A, B) VALUES ('1', 'I '); Insert into test (A, B) VALUES ('1 '); Insert into test (A, B) VALUES ('2', '1 '); Insert into test (A, B) VALUES ('2', 'start '); COMMIT; Select a, B FROM TEST A B -------------------- 1.

information entropy not conducive to computer processing? I am afraid it is difficult to draw conclusions in this regard. Comparing the input speed of Chinese characters and English letters does not explain the problem, because "word" and "word" are different concepts. To compare two different texts in Chinese and English with the same content, calculate the difference of the number of keys.
