CREATE TABLE table_name_19 (decimal VARCHAR2, max_memory__kwords_ VARCHAR2, byte_string VARCHAR2, memory_map VARCHAR2)

What is the decimal value when the memory map and byte string are standard, and the max memory is 512?
SELECT decimal FROM table_name_19 WHERE byte_string = "standard" AND memory_map = "standard" AND max_memory__kwords_ = 512
SELECT "decimal" FROM "table_name_19" WHERE "byte_string" = "standard" AND "max_memory__kwords_" = 512 AND "memory_map" = "standard"
