define external function SQLSetArrayAsString
( read-only SQL_array_type Array,
value integer ElementPos,
value stream StreamValue )
Sets an element in the data area of the SQL_array_type variable to the specified stream value. The input stream must contain only text data, with no embedded nulls. The stream length is identified by the end of the stream or the first detected null byte.
Input arguments:
The following code demonstrates how to use SQLSetArrayAsString to set the element string value.
local SQL_Array_type Array local SQL_Array_type ArrayCopy local stream ArrayStringValue local integer ArrayStringLen local integer i SQLSetArraySize( Array, 20, 5 )
In the following code, SQLGetArrayAsString to check initial values.
set i to 0
repeat
set ArrayStringValue to SQLGetArrayAsString( Array, i )
set ArrayStringLen to (length of ArrayStringValue)
output "Initial string value[%d(i)] = %g(ArrayStringValue) "
output "(length = %d(ArrayStringLen))%n"
increment i
exit when i=5
again
Next, SQLSetArrayAsString sets the stream values.
set i to 0
repeat
set ArrayStringValue to "*" ||* (i+1) || "%0#- post null"
SQLSetArrayAsString( Array, i, ArrayStringValue )
increment i
exit when i=5
again
Finally, SQLGetArrayAsString is used to check the current values of the stream.
set i to 0
repeat
set ArrayStringValue to SQLGetArrayAsString( Array, i )
set ArrayStringLen to (length of ArrayStringValue)
output "Current string value[%d(i)] = %g(ArrayStringValue) "
output "(length = %d(ArrayStringLen))%n"
increment i
exit when i=5
again
