DBMS_STATS with Looping - oracle

Question

I just tried to learn new things. I just make a experiment to analyze tables with looping. But, I found error that said
'Invalid reference to variable 'indx'
. If I take out the DBMS_STATS 'thing' and just to print the result, it works. But when I tried to analyze the tables, the error came out.
CREATE OR REPLACE PROCEDURE ANALYZE_TABLE
AS
CURSOR table_cur IS
SELECT TABLE_NAME
FROM ALL_TABLES
WHERE TABLE_NAME LIKE 'STUDENT%';
table_nm table_cur%ROWTYPE;
TYPE table_nms IS TABLE OF table_nm%TYPE;
l_table table_nms;
BEGIN
OPEN table_cur;
FETCH table_cur BULK COLLECT INTO l_table;
CLOSE table_cur;
FOR indx IN 1..l_table.COUNT LOOP
IF (indx.table_name = 'STUDENT_DETAILS') THEN
dbms_stats.gather_table_stats(ownname => 'ADMIN', tabname => indx.table_name , estimate_percent => 100,
method_opt => 'for all indexed columns size auto',
degree => 4 ,cascade => TRUE );
ELSIF (indx.table_name = 'STUDENT_ALLOWANCE' OR indx.table_name = 'STUDENT_PAYMENT')
THEN
DBMS_STATS.GATHER_TABLE_STATS (ownname => 'ADMIN', tabname => indx.table_name , estimate_percent => 100,
method_opt => 'for all indexed columns size auto',
degree => 4 ,cascade => TRUE );
ELSE
DBMS_STATS.GATHER_TABLE_STATS (ownname => 'ADMIN', tabname => indx.table_name , estimate_percent => 100,
method_opt => 'for all indexed columns size auto',
degree => 4 ,cascade => TRUE );
END IF;
--DBMS_OUTPUT.PUT_LINE(l_table(indx).TABLE_NAME);
END LOOP;
END ANALYZE_TABLE;
Any suggestion? Or a better way to analyze tables with this loop?
Thank you in advance for anyone that helping me. :)

Answer 1

You need to reference the contents of your array, not the loop index. The loop index tells you which element in the array. So:
IF (l_table(indx).table_name = 'STUDENT_DETAILS') THEN
and so on

Answer 2

You should reference the values in your table as follows:
if (l_table(indx).table_name = 'STUDENT_DETAILS') ...
