Możesz to zrobić za pomocą kolekcji:
CREATE TYPE VARCHAR2s_Table IS TABLE OF VARCHAR2(100);
/
Następnie wprowadź swoje dane w ten sposób:
SELECT *
FROM table_name
WHERE user_data MEMBER OF VARCHAR2s_Table( 'abc123','xyz456','pqr789' );
Alternatywnie :
Możesz utworzyć funkcję do dzielenia danych i generowania kolekcji:
CREATE TYPE VARCHAR2_TABLE AS TABLE OF VARCHAR2(4000);
/
CREATE OR REPLACE FUNCTION split_String(
i_str IN VARCHAR2,
i_delim IN VARCHAR2 DEFAULT ','
) RETURN VARCHAR2_TABLE DETERMINISTIC
AS
p_result VARCHAR2_TABLE := VARCHAR2_TABLE();
p_start NUMBER(5) := 1;
p_end NUMBER(5);
c_len CONSTANT NUMBER(5) := LENGTH( i_str );
c_ld CONSTANT NUMBER(5) := LENGTH( i_delim );
BEGIN
IF c_len > 0 THEN
p_end := INSTR( i_str, i_delim, p_start );
WHILE p_end > 0 LOOP
p_result.EXTEND;
p_result( p_result.COUNT ) := SUBSTR( i_str, p_start, p_end - p_start );
p_start := p_end + c_ld;
p_end := INSTR( i_str, i_delim, p_start );
END LOOP;
IF p_start <= c_len + 1 THEN
p_result.EXTEND;
p_result( p_result.COUNT ) := SUBSTR( i_str, p_start, c_len - p_start + 1 );
END IF;
END IF;
RETURN p_result;
END;
/
Następnie możesz zrobić:
SELECT *
FROM table_name
WHERE user_data MEMBER OF split_String( 'abc123,xyz456,pqr789', ',' );
lub:
SELECT *
FROM table_name
WHERE user_data MEMBER OF split_String( TRIM( '''' FROM '''abc123'',''xyz456'',''pqr789''' ), ''',''' );
