sql - Show data that is only from a specific quarter -


I need to show the data that is any quarter of any year only. Where I am trying to use to_date in the segment but it is giving me an error, not sure which mistake I am getting. (Use Oracle 10g)

code: 

  select product_name, include a_product p a_item i p.product_id = i.product_id a_sales_order so many I.order_id = so.order_id join a_customer C. so.customer_id = c.customer_id Where regexp_like (PRODUCT_NAME, 'transducer') and ORDER_DATE = TO_DATE (2, 'Q')

And that part is where I'm having trouble, it is giving me a "format code date can not appear in the date format" ORDER_DATE is the table that I have to find out how to sell The use of what was done in the second quarter of the year was within the area.

You have the debate behind. I think you want to be: 

  and TO_CHAR (ORDER_DATE, 'Q') = '2'

The function TO_CHAR () (in this context) takes a date and it is a string Formatted as What is the string? In it, a string with a quarter, then you want to compare it to the price.

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
