PostgreSQL到OracleSQL查询转换需要帮助(PostgreSQL to OracleSQL query convertion help needed)

我这里有一个PostgreSQL查询，它从“word”表列中计算大写字符：

sum(length(substring(word from '^[A-Z]*'))) as capitalized_sum;

我需要将其转换为Oracle SQL查询。

我试过了：

sum(length(regexp_like('^[A-Z]*'))) from word as capitalized_sum;

但这给了我“SQL命令没有正确结束”的消息。 有帮助吗？

I have a PostgreSQL query here that counts capitalized characters from a "word" table column:

sum(length(substring(word from '^[A-Z]*'))) as capitalized_sum;

I need to convert it to Oracle SQL query.

I tried:

sum(length(regexp_like('^[A-Z]*'))) from word as capitalized_sum;

but that gives me "SQL command not properly ended" message. Any help?

最满意答案

我想我找到了我需要的东西。 这是OracleSQL查询：

select sum(length(REGEXP_SUBSTR(word, '^[A-Z]*'))) as capitalized_sum from mytable;

I think I found what I need. Here is the OracleSQL query:

select sum(length(REGEXP_SUBSTR(word, '^[A-Z]*'))) as capitalized_sum from mytable;
