Function Reference


Fast encodes binary data (exclusively) for use in SQLite statements

#include <SQLite.au3>
_SQLite_FastEncode ( $vData )


$vData Data To be encoded (Binary only)

Return Value

Success: an encoded binary string.
Failure: an empty string and sets the @error flag to non-zero.
@error: 1 - Data is not a binary type


The encoded string is already wrapped with single quotes.
For example Chr(0) & Chr(1) would look like X'0001'.
The encoded string can be decoded by Sqlite and stored in binary state as a BLOB.
For strings to be stored as TEXT, use _SQLite_Escape().
For numeric value to be stored as such, use simple concatenation.
