Answer 1

语法错误是因为在Oracle中if else应该采用如下所示的格式。

IF condition1 THEN
   {...statements to execute when condition1 is TRUE...}

ELSIF condition2 THEN
   {...statements to execute when condition2 is TRUE...}

ELSE
   {...statements to execute when both condition1 and condition2 are FALSE...}

END IF;

PL SQL LOOP逻辑if if else
