declarations
prices: array(1001..1004) of real
colors: array(1001..1004) of string
allcolors: set of string
end-declarations
OCIexecute("select color from pricelist", allcolors)
OCIexecute("select articlenum,color,price from pricelist",
[colors,prices])
OCIexecute("create table newtab (ndx integer, price double)")
OCIexecute("insert into newtab (ndx, price) values (:1,:2)", prices)
Further information
1. This procedure executes the given SQL command. The user is referred to the Oracle documentation for further information on PL/SQL.
2. For output commands (like
insert into) this procedure accepts arrays, sets and lists of basic types (integer, real, string or Boolean) as well as module types for which from/to string convertions are available. Record types composed of scalars or other records can also be used (the fields that cannot be handled are silently ignored). It is also possible to use a list of arrays of basic types (all arrays must be indexed by the same sets) or a list of scalar elements of different basic or module types.
3. For input commands (like
select from) the same restrictions apply for arrays,lists and list of arrays but sets must be of a basic type.
