Executing sql in procedure with concatenated command string










0















I have this here:



create procedure test_ins(IN tab varchar(128))
Language sql
begin
DECLARE stmt_ins STATEMENT;
DECLARE v_query varchar(2048);
DECLARE test varchar(20);
DECLARE test_tab varchar(20);
set test = 'HERE IT IS';
set test_tab = tab;
set v_query= 'INSERT INTO '||test_tab||'(test, free) values (test,'''')';
PREPARE stmt_ins from v_query;
EXECUTE stmt_ins;

end@


The problem is that it seems to run (no error message) but there is nothing in the table....



Any ideas?
Thanks

    Oh found it, we are forgetting single quotes, should be like 'Here it is', which is '''||test||''' . Updated my answer, check that.

I think you need to change test to '||test||' in set v_query like below:



create procedure test_ins(IN tab varchar(128))
Language sql
begin
DECLARE stmt_ins STATEMENT;
DECLARE v_query varchar(2048);
DECLARE test varchar(20);
DECLARE test_tab varchar(20);
set test = 'HERE IT IS';
set test_tab = tab;
set v_query= 'INSERT INTO '||test_tab||'(test, free) values ( '''||test||''','''')';
PREPARE stmt_ins from v_query;
EXECUTE stmt_ins;

end@

    Debugger works fine for me, as local-admin, so you've got a different issue not related to your question. The exact code I show in my answer works correctly. Your code may differ. If the exact code above yields neither and insert nor an error, then you are omitting some information.
