rquindt | Hello
I need in my Program partly only 1 byte long variables.
yet help I me with a 1 characters String.
How see it really with the Speicherplatzbedarf from?
would be I instead of String Integer take, wären the 4 Bytes.
is evtl at nächten XProfan-Update at a expansion the
variables-Types virtual ?
In Firebird go byte supported. |

H.Brill | If it really about Platzbedarf goes, I really
not suspect, can too a area take.
with Dim area, 1 is the then really only one byte
large.
comes always hereon on, what hineinschreiben
would like. for a z.B. individual letters power
But not plenty sense. If one now but one byte
need, circa any states (0|1) To Save,
takes is a normal Integervariable. one remember
itself : 1 byte = 8 bit. one has of course 32 bit available,
but one need Yes only soviele bit To occupy, How one
need.
with whom Memory-Variables has it whom disadvantage, that one
then too The functions to that reading and write
using must. in the entrapment one Buchstabens must then
with the ASCII-code hantiert go. or one takes
a Bereichs-String. there comes one but always on
2 Bytes : the eigentliche characters + Chr$(0).
means would for a Bytefeld in Firebird only one byte-area
in question come. |

W. | by the automatic conversion is a byte as Datentyp not necessary.
for the reading/write in binären Files uses one GetByte/PutByte.
SQL
with Select and Insert go The Integerwerte automatically transformed. want one ensuring, the it To keinem Überlauf comes, then testing one The values with Between() or bring tappt im dunkeln into suitable area with brat().
there's many Examples in the Help Firebird. |
