I am trying to find a count of 1st day of the month between two dates in oracle sql, similar to the INTCK function in SAS. *EXAMPLE: */
/* CHRG_OFF_DT = 1/15/2023 */
/* EFF_DT = 4/27/2023 */
/* */
/* FIRST OF MONTHS: */
/* 1) 02/01/2023 */
/* 2) 03/01/2023 */
/* 3) 04/01/2023 */
/* */
/* MONTHS SINCE CHARGE OFF = 3
