我在这里:
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@
问题在于它似乎正在运行(没有错误消息),但是表中没有任何内容。...
有什么想法吗? 谢谢

似乎您没有使用调试器...请尝试在IBM Data Studio中使用调试器(免费download)。
create or replace procedure test_ins(IN tab varchar(128))
Language sql
specific test_ins
begin
DECLARE v_query varchar(2048);
DECLARE test varchar(20);
DECLARE test_tab varchar(20);
DECLARE stmt_ins STATEMENT;
set test = 'HERE IT IS';
set test_tab = tab;
set v_query= 'INSERT INTO '||test_tab||'(test, free) values (''test'','''')';
call dbms_output.put_line(v_query);
PREPARE stmt_ins from v_query;
EXECUTE stmt_ins;
end@

我认为您需要将测试更改为“ ||测试||”在如下所示的v_query集合中:
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@
