Can any body let me know the query?

Question

Hi
I want all the table names and all the column names from entire database which is having some pattern
Ex:i want table name and corresponding column names where the column data is having substring 'oracle'
if i have 'oracle' as substring data in 2 columns of 3 tables in my database then it should give me table name and corresponding column names in that table
Thanks in advance...

Answer 1

yes, i have tried with the following block
DECLARE
V_CURSOR VARCHAR2(4000);
V_TABLE_NAME VARCHAR2(4000);
V_COLUMN_NAME VARCHAR2(4000);
CURSOR GET_TABLE IS SELECT TABLE_NAME FROM user_tables;
CURSOR GET_COLUMN IS
SELECT COLUMN_NAME FROM USER_TAB_COLUMNS
WHERE TABLE_NAME IN (SELECT TABLE_NAME FROM USER_TABLES) AND DATA_TYPE='VARCHAR2';
BEGIN
FOR TAB IN GET_TABLE
LOOP
FOR COL IN GET_COLUMN
LOOP
EXECUTE IMMEDIATE 'SELECT '||TAB.TABLE_NAME||','||COL.COLUMN_NAME||' FROM '||TAB||','||COL||' WHERE '||COL.COLUMN_NAME||' LIKE '||'"%oracle%"'||'INTO '||V_TABLE_NAME||','||V_COLUMN_NAME;
DBMS_OUTPUT.PUT_LINE(V_TABLE_NAME||' '||V_COLUMN_NAME);
END LOOP;
END LOOP;
END;
But unable to proceed
