Learn Oracle: Datatypes for SQL and PL/SQL, Numbers An associative array (INDEX BY TABLE) index. Both PLS_INTEGER and BINARY_INTEGER allow whole numbers only. Decimal fractions are rounded to the nearest whole number. There performance benefits to using PLS_INTEGER or BINARY_INTEGER is some places (as opposed to a NUMBER). Using the TABLE Operator with Locally Defined Types in PL/SQL Using the TABLE Operator with Locally Defined Types in PL/SQL. In Oracle 12c, the TABLE operator can now be used in PL/SQL with locally defined types. In previous releases, the TABLE operator would only work with locally defined types if they were used within pipelined table functions. The removal of this restriction means this functionality is Collections -Associated Arrays(index by Table),Nested ... Your program needs small lookups; The collection can be made at runtime in the memory when the package/ procedure is initialized; The data volume is unknown beforehand

PLS_INTEGER is more efficient than BINARY_INTEGER so it's … Binary integer decimal - Wikipedia In the binary integer decimal (BID) encoding, it is encoded as a binary number. Format. Using the fact that 2 10 = 1024 is only slightly more than 10 3 = 1000, 3n-digit decimal numbers can be efficiently packed into 10n binary bits. However, the IEEE formats have significands of 3n+1 digits, which would table of varchar2(200) index by binary_integer : Varchar ...
BINARY_INTEGER - defined in the STANDARD package as a subtype of INTEGER. Variables declared as BINARY_INTEGER can be assigned values between -2 31 +1 .. 2 31-1, aka -2,147,483,647 to 2,147,483,647. Prior to Oracle9i Database Release 2, BINARY_INTEGER was the only indexing datatype allowed for associative arrays (aka, index-by tables), as in:

Nov 24, 2016 · index by binary_integer; If the element type is a record type, every field in the record must have a scalar datatype such as CHAR, DATE, or NUMBER. To specify the element type, you can use %TYPE to provide the datatype of a variable or database column Linear programming - Wikipedia Linear programming (LP, also called linear optimization) is a method to achieve the best outcome (such as maximum profit or lowest cost) in a mathematical model whose requirements are represented by linear relationships. Linear programming is a special case of mathematical programming (also known as mathematical optimization). Declare Table - Oracle PL/SQL - SS64.com DECLARE . Declare TABLE TYPE variables in a PL/SQL declare block. Table variables are also known as index-by table or array.
