Binary encodes a string, number or binary data for use as BLOB in SQLite statements
#include <SQLite.au3>
_SQLite_Encode ( $vData )
| $vData | Data To be encoded (String, Number or Binary) |
| Success: | an encoded string. |
| Failure: | an empty string and sets the @error flag to non-zero. |
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.
