如何把以下 MySql 语句转换为 Oracle 语句？

[国产星期八]

MySql 语句如下：

set SQL_STR :=CONCAT('SELECT COUNT(DISTINCT CALLERPHONE) into @T_VAR_DOWN_USERSTAT FROM ',USER_MONTH_TABLE ,' where DISCOVER_WAY =1');
     CALL EXECUTE_IMMEDIATE( SQL_STR );
     SET VAR_DOWN_USERSTAT=@T_VAR_DOWN_USERSTAT;

如何把上面 MySql 语句转换为 Oracle 语句？

看这结帖率也是醉了~

SQL_STR :='SELECT COUNT(DISTINCT CALLERPHONE) into :a ' || USER_MONTH_TABLE || ' where DISCOVER_WAY =1';
      EXECUTE_IMMEDIATE SQL_STR USING VAR_DOWN_USERSTAT;

话说mysql不太熟，你试试吧 PS：看不上concat，能用||就用||，其实concat应该不用改的。
