Question

我的SQL查询是

SELECT *
  FROM fchost.iv_stock_details
 WHERE cod_stock = '16' AND cod_stock_branch = '1134'

它将返回多列结果，但我担心的是一个特定列，即库存状态，其值为UUUUIIII，总共会有200个数字

我需要计算I和U的数量

例如

UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUIUUIUUUUUUUUUUUUUUIUUUIUUUUUUUUUUUUUUUUUUUUUUIIUUUIUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUIIUUUUUUUUUUUUUUUUUUUUUUUUUIUUUUUUUUUUUUUUUUUUUUUIUUUUUUUUUUUUUUUIUUUUUIIIIIIII

在库存状态列中，结果将是这样，我需要分别计算该值并显示

例如，如果“ U”为180，我想显示位置值（从1到200）另外，如果“我”为20，则需要放置值并显示

您可以使用the regexp_count() function，它具有由您要查找的字符组成的非常简单的模式：

SELECT regexp_count(stock_status, 'U') as u_count,
       regexp_count(stock_status, 'I') as i_count
  FROM fchost.iv_stock_details
 WHERE cod_stock = '16' AND cod_stock_branch = '1134';

   U_COUNT    I_COUNT
---------- ----------
       180         20

需要在一个字段中计算值
