PL/SQL Oracle dbms_output 使均匀 output

Question

我试图寻找答案，但没有找到。

即使每篇文章的文章长度不同，我也很乐意让我的 output 均匀。 这就是长度不同时我所拥有的

这是有兴趣的人看的代码

set serverout ON format WORD_WRAPPED;

将您的 output 行更改为类似

DBMS_OUTPUT.PUT_LINE(LPAD(rec_facture.d_qty, 3))         || -- d_qty : 3 characters
                     RPAD(' ', 21)                       || -- blanks
                     RPAD(rec_facture.p_description, 29) || -- p_description : 29 chars
                     LPAD(rec_facture.d_prix, 13)        || -- d_prix : 13 chars
                     RPAD(' ', 23)                       || -- blanks
                     LPAD(rec_facture.d_prixTotal, 13));    -- d_prixTotal : 13 chars
